dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

Commit 2 is a quick fix for part of https://github.com/dotnet/roslyn/issues/56044. | 333fred | "2021-09-03T00:32:48Z" | "2021-09-14T23:49:39Z" | 7bc2467b978ba0d6df8576e241c9ed13e05a6c08 | d4315a175368888f7d6baf4804d1ae9b57fcb68d | Use SpillSequences when appropriate instead of Sequences. Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.

dotnet/roslyn | 56,153 | Use SpillSequences when appropriate instead of Sequences | Fixes https://github.com/dotnet/roslyn/issues/54704. This means that, instead of expressions that need to `&& true` in the case of builders with void returns but a bool constructor parameter, we now generate `if (builderConstructorSuccess) { appendCalls }`. As part of this, I simplified the code around how the sequence/spillsequence is actually generated to reduce unnecessary sequence nesting, but that had no affect on the final codegen.
