Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases. - Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code
Fixes https://github.com/dotnet/runtime/issues/66273

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

/// This is a thread-safe hash table which maps string keys to values of type TValue. It is assumed that the string key is embedded in the hashed value
/// and can be extracted via a call to ExtractKeyDelegate (in order to save space and allow cleanup of key if value is released due to a WeakReference
/// TValue releasing its target).
/// </summary>
/// <remarks>
/// All methods on this class are thread-safe.
///
/// When the hash table fills up, it is necessary to resize it and rehash all contents. Because this can be expensive,
/// a lock is taken, and one thread is responsible for the resize. Other threads which need to add values must wait
/// for the resize to be complete.
///
/// Thread-Safety Notes
/// ===================
///
/// 1. Because performance and scalability are such a concern with the global name table, I have avoided the use of
/// BIFALOs (Big Fat Locks). Instead, I use CompareExchange, Interlocked.Increment, memory barriers, atomic state objects,
/// etc. to avoid locks. Any changes to code which accesses these variables should be carefully reviewed and tested,
/// as it can be *very* tricky. In particular, if you don't understand the CLR memory model or if you don't know
/// what a memory barrier is, DON'T attempt to modify this code. A good discussion of these topics can be found at
/// <![CDATA[http://discuss.develop.com/archives/wa.exe?A2=ind0203B&L=DOTNET&P=R375]]>.
///
/// 2. Because I am not sure if the CLR spec has changed since versions 1.0/1.1, I am assuming the weak memory model that
/// is described in the ECMA spec, in which normal writes can be reordered. This means I must introduce more memory
/// barriers than otherwise would be necessary.
///
/// 3. There are several thread-safety concepts and patterns I utilize in this code:
/// a. Publishing -- There are a small number of places where state is exposed, or published, to multiple threads.
/// These places are marked with the comment "PUBLISH", and are key locations to consider when
/// reviewing the code for thread-safety.
///
/// b. Immutable objects -- Immutable objects initialize their fields once in their constructor and then never modify
/// them again. As long as care is taken to ensure that initial field values are visible to
/// other threads before publishing the immutable object itself, immutable objects are
/// completely thread-safe.
///
/// c. Atomic state objects -- Locks typically are taken when several pieces of state must be updated atomically. In
/// other words, there is a window in which state is inconsistent, and that window must
/// be protected from view by locking. However, if a new object is created each time state
/// changes (or state changes substantially), then during creation the new object is only
/// visible to a single thread. Once construction is complete, an assignment (guaranteed
/// atomic) can replace the old state object with the new state object, thus publishing a
/// consistent view to all threads.
///
/// d. Retry -- When several threads contend over shared state which only one is allowed to possess, it is possible
/// to avoid locking by repeatedly attempting to acquire the shared state. The CompareExchange method
/// is useful for atomically ensuring that only one thread succeeds, and other threads are notified that
/// they must retry.
///
/// 4. All variables which can be written by multiple threads are marked "SHARED STATE".

/// TValue releasing its target).
/// </summary>
/// <remarks>
/// All methods on this class are thread-safe.
///
/// When the hash table fills up, it is necessary to resize it and rehash all contents. Because this can be expensive,

/// for the resize to be complete.
///
/// Thread-Safety Notes
/// ===================
///
/// 1. Because performance and scalability are such a concern with the global name table, I have avoided the use of
/// BIFALOs (Big Fat Locks). Instead, I use CompareExchange, Interlocked.Increment, memory barriers, atomic state objects,
/// etc. to avoid locks. Any changes to code which accesses these variables should be carefully reviewed and tested,
/// as it can be *very* tricky. In particular, if you don't understand the CLR memory model or if you don't know
/// what a memory barrier is, DON'T attempt to modify this code. A good discussion of these topics can be found at
/// <![CDATA[http://discuss.develop.com/archives/wa.exe?A2=ind0203B&L=DOTNET&P=R375]]>.
///
/// 2. Because I am not sure if the CLR spec has changed since versions 1.0/1.1, I am assuming the weak memory model that
/// is described in the ECMA spec, in which normal writes can be reordered. This means I must introduce more memory
/// barriers than otherwise would be necessary.
///
/// 3. There are several thread-safety concepts and patterns I utilize in this code:
/// a. Publishing -- There are a small number of places where state is exposed, or published, to multiple threads.
/// These places are marked with the comment "PUBLISH", and are key locations to consider when
/// reviewing the code for thread-safety.
///
/// b. Immutable objects -- Immutable objects initialize their fields once in their constructor and then never modify
/// them again. As long as care is taken to ensure that initial field values are visible to
/// other threads before publishing the immutable object itself, immutable objects are
/// completely thread-safe.
///
/// c. Atomic state objects -- Locks typically are taken when several pieces of state must be updated atomically. In
/// other words, there is a window in which state is inconsistent, and that window must
/// be protected from view by locking. However, if a new object is created each time state
/// changes (or state changes substantially), then during creation the new object is only
/// visible to a single thread. Once construction is complete, an assignment (guaranteed
/// atomic) can replace the old state object with the new state object, thus publishing a
/// consistent view to all threads.
///
/// d. Retry -- When several threads contend over shared state which only one is allowed to possess, it is possible
/// to avoid locking by repeatedly attempting to acquire the shared state. The CompareExchange method
/// is useful for atomically ensuring that only one thread succeeds, and other threads are notified that
/// they must retry.
///
/// 4. All variables which can be written by multiple threads are marked "SHARED STATE".

Fix some exception messages for BindHandle-like cases

- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code
Fixes https://github.com/dotnet/runtime/issues/66273

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix some exception messages for BindHandle-like cases
|
- Updated `ThrowHelper.ThrowApplicationException` to get and include an error message
- CoreCLR seems to have special code for producing exception messages from HRs and differs a bit from `Marshal.GetExceptionForHR`, forked to throw from the native side in CoreCLR to retain the previous messages
- Enabled the disabled tests, disabled a `BindHandle` test on Unixes where it now throws `PNSE` before `ArgumentNullException`, kept some tests disabled for Mono since the tests check for specific parts of exception messages that are specific to CoreCLR's code

Fix code coverage gaps in RegexGenerator and fix RegexCompiler bug
|
Noticed some easily-fillable gaps in code coverage for RegexGenerator. In adding those tests, found and fixed a bug in RegexCompiler where we were incorrectly using `Call(s_spanIndexOfSpan)` instead of `Call(s_spanIndexOfAnySpan)`.

// RegexWriter; the interpreter would then sit in a loop processing those opcodes, and the RegexCompiler iterated through the
// opcodes generating code for each equivalent to what the interpreter would do albeit with some decisions made at compile-time
// rather than at run-time. This approach, however, lead to complicated code that wasn't pay-for-play (e.g. a big backtracking
// jump table that all compilations went through even if there was no backtracking), that didn't factor in the shape of the
// tree (e.g. it's difficult to add optimizations based on interactions between nodes in the graph), and that didn't read well
// when decompiled from IL to C# or when directly emitted as C# as part of a source generator.

// This implementation is instead based on directly walking the RegexNode tree and outputting code for each node in the graph.
// A dedicated for each kind of RegexNode emits the code necessary to handle that node's processing, including recursively
// calling the relevant function for any of its children nodes. Backtracking is handled not via a giant jump table, but instead
// by emitting direct jumps to each backtracking construct. This is achieved by having all match failures jump to a "done"
// label that can be changed by a previous emitter, e.g. before EmitLoop returns, it ensures that "doneLabel" is set to the
// label that code should jump back to when backtracking. That way, a subsequent EmitXx function doesn't need to know exactly
// where to jump: it simply always jumps to "doneLabel" on match failure, and "doneLabel" is always configured to point to
// the right location. In an expression without backtracking, or before any backtracking constructs have been encountered,
// "doneLabel" is simply the final return location from the TryMatchAtCurrentPosition method that will undo any captures and exit, signaling to

// RegexWriter; the interpreter would then sit in a loop processing those opcodes, and the RegexCompiler iterated through the
// opcodes generating code for each equivalent to what the interpreter would do albeit with some decisions made at compile-time
// rather than at run-time. This approach, however, lead to complicated code that wasn't pay-for-play (e.g. a big backtracking
// jump table that all compilations went through even if there was no backtracking), that didn't factor in the shape of the
// tree (e.g. it's difficult to add optimizations based on interactions between nodes in the graph), and that didn't read well
// when decompiled from IL to C# or when directly emitted as C# as part of a source generator.

// This implementation is instead based on directly walking the RegexNode tree and outputting code for each node in the graph.
// A dedicated for each kind of RegexNode emits the code necessary to handle that node's processing, including recursively
// calling the relevant function for any of its children nodes. Backtracking is handled not via a giant jump table, but instead
// by emitting direct jumps to each backtracking construct. This is achieved by having all match failures jump to a "done"
// label that can be changed by a previous emitter, e.g. before EmitLoop returns, it ensures that "doneLabel" is set to the
// label that code should jump back to when backtracking. That way, a subsequent EmitXx function doesn't need to know exactly
// where to jump: it simply always jumps to "doneLabel" on match failure, and "doneLabel" is always configured to point to
// the right location. In an expression without backtracking, or before any backtracking constructs have been encountered,
// "doneLabel" is simply the final return location from the TryMatchAtCurrentPosition method that will undo any captures and exit, signaling to

Fix code coverage gaps in RegexGenerator and fix RegexCompiler bug
|
Noticed some easily-fillable gaps in code coverage for RegexGenerator. In adding those tests, found and fixed a bug in RegexCompiler where we were incorrectly using `Call(s_spanIndexOfSpan)` instead of `Call(s_spanIndexOfAnySpan)`.

// In .NET Framework and up through .NET Core 3.1, the code generated for RegexOptions.Compiled was effectively an unrolled
// version of what RegexInterpreter would process. The RegexNode tree would be turned into a series of opcodes via
// RegexWriter; the interpreter would then sit in a loop processing those opcodes, and the RegexCompiler iterated through the
// opcodes generating code for each equivalent to what the interpreter would do albeit with some decisions made at compile-time
// rather than at run-time. This approach, however, lead to complicated code that wasn't pay-for-play (e.g. a big backtracking
// jump table that all compilations went through even if there was no backtracking), that didn't factor in the shape of the
// tree (e.g. it's difficult to add optimizations based on interactions between nodes in the graph), and that didn't read well
// when decompiled from IL to C# or when directly emitted as C# as part of a source generator.
//
// This implementation is instead based on directly walking the RegexNode tree and outputting code for each node in the graph.
// A dedicated for each kind of RegexNode emits the code necessary to handle that node's processing, including recursively
// calling the relevant function for any of its children nodes. Backtracking is handled not via a giant jump table, but instead
// by emitting direct jumps to each backtracking construct. This is achieved by having all match failures jump to a "done"
// label that can be changed by a previous emitter, e.g. before EmitLoop returns, it ensures that "doneLabel" is set to the
// label that code should jump back to when backtracking. That way, a subsequent EmitXx function doesn't need to know exactly
// where to jump: it simply always jumps to "doneLabel" on match failure, and "doneLabel" is always configured to point to
// the right location. In an expression without backtracking, or before any backtracking constructs have been encountered,
// "doneLabel" is simply the final return location from the TryMatchAtCurrentPosition method that will undo any captures and exit, signaling to

// In .NET Framework and up through .NET Core 3.1, the code generated for RegexOptions.Compiled was effectively an unrolled
// version of what RegexInterpreter would process. The RegexNode tree would be turned into a series of opcodes via
// RegexWriter; the interpreter would then sit in a loop processing those opcodes, and the RegexCompiler iterated through the
// opcodes generating code for each equivalent to what the interpreter would do albeit with some decisions made at compile-time
// rather than at run-time. This approach, however, lead to complicated code that wasn't pay-for-play (e.g. a big backtracking
// jump table that all compilations went through even if there was no backtracking), that didn't factor in the shape of the
// tree (e.g. it's difficult to add optimizations based on interactions between nodes in the graph), and that didn't read well
// when decompiled from IL to C# or when directly emitted as C# as part of a source generator.
//
// This implementation is instead based on directly walking the RegexNode tree and outputting code for each node in the graph.
// A dedicated for each kind of RegexNode emits the code necessary to handle that node's processing, including recursively
// calling the relevant function for any of its children nodes. Backtracking is handled not via a giant jump table, but instead
// by emitting direct jumps to each backtracking construct. This is achieved by having all match failures jump to a "done"
// label that can be changed by a previous emitter, e.g. before EmitLoop returns, it ensures that "doneLabel" is set to the
// label that code should jump back to when backtracking. That way, a subsequent EmitXx function doesn't need to know exactly
// where to jump: it simply always jumps to "doneLabel" on match failure, and "doneLabel" is always configured to point to
// the right location. In an expression without backtracking, or before any backtracking constructs have been encountered,
// "doneLabel" is simply the final return location from the TryMatchAtCurrentPosition method that will undo any captures and exit, signaling to

Fix code coverage gaps in RegexGenerator and fix RegexCompiler bug
|
Noticed some easily-fillable gaps in code coverage for RegexGenerator. In adding those tests, found and fixed a bug in RegexCompiler where we were incorrectly using `Call(s_spanIndexOfSpan)` instead of `Call(s_spanIndexOfAnySpan)`.

Fix code coverage gaps in RegexGenerator and fix RegexCompiler bug

Noticed some easily-fillable gaps in code coverage for RegexGenerator. In adding those tests, found and fixed a bug in RegexCompiler where we were incorrectly using `Call(s_spanIndexOfSpan)` instead of `Call(s_spanIndexOfAnySpan)`.

Fix code coverage gaps in RegexGenerator and fix RegexCompiler bug

Noticed some easily-fillable gaps in code coverage for RegexGenerator. In adding those tests, found and fixed a bug in RegexCompiler where we were incorrectly using `Call(s_spanIndexOfSpan)` instead of `Call(s_spanIndexOfAnySpan)`.
