here is my test code
```
(module
(func (result i32)
(i32.add (i32.const 624485) (i32.const 2))))
```
LEB of 624485 [should be 0xE58E26](https://en.wikipedia.org/wiki/LEB128#Unsigned_LEB128)
But from the prototype if get
```
; function 0
....
0000014: 0a ; OPCODE_I32_CONST
0000015: 6587 0900 ; u32 literal
....
```
how is 0x65870900 derived?

I have a test that generated the following code, and fed it into sexpr-wasm
(module
(func $foomore(call $foo (i32.const 0x0)) )
(func $foo (param i32)(nop))
)
Note the lack of space between $foomore and its opening paren. Sometime between rev 64fb062d and rev 7601228b this stopped being accepted by the parser, which now issues the following confusing error:
<filename>:2:23: expected '(', not "$foo"
It looks like the "(call" is getting sucked into the "$foomore" token.
I don't actually know what the rules of s-expressions are in that case; maybe this is the correct behavior?

The spec interpreter reports assertion errors with line numbers from the source. This would be really handy for debugging codegen issues (e.g. in a test suite with hundreds of assertions, which one is failing?). Currently WAOT just tracks and prints the count (i.e. "assertion number X failed") but a line number would be even better. That would have more immediate utility but at some point it might become nice to have line information for expressions too (maybe I want to generate debug info?) That's sort of a speculative use case and may not matter during the time horizon that sexpr-wasm matters, but something that might be nice to have in mind. I'd be happy for asserts for now.
I don't know if it would be better just to hang SourceLocations off of some existing data structure, or pass extra callback args or what, it doesn't matter much to me, I don't think.

I have the following snippet in my code, with the idea of creating a compilation error if an impossible set of defines are set:
```
%if LABEL && ALTLABEL
%error cant have LABEL and ALTLABEL together
%endif
```
In nasm this behaves as expected. In yasm I get the message, but then yasm returns with exit code 0, with the broken code as output.
I can workaround it by specifying "-Werror": "Treat warnings as errors". But it already is an error.
I think the error is here:
https://github.com/yasm/yasm/blob/121ab150b3577b666c79a79f4a511798d7ad2432/modules/preprocs/nasm/nasm-pp.c#L2875
should be ERR_FATAL instead of ERR_NONFATAL
|
%error macro only leads to a warning/different behaviour than nasm

I might be asking this in the wrong place, but after creating an installer using this tool, how do I get the newly created installer to run silently without any user interaction?

Which flag allows for silent installation?

This seems to appear every time I pass `-Werror` to yasm. It not only seems redundant, but it also makes it harder to visually identify any actual errors. What's the intention of this message? Is it possible to suppress it? `nasm` doesn't seem to print this.

In nasm `mov a, [foo wrt ..got]` (or `..gotpc`?) creates a GOTPCREL relocation, but yasm specifies this as `mov a, [foo wrt ..gotpcrel]`. Is the syntax difference intentional?

x86-64 GOTPCREL wrt syntax doesn't match nasm

I enabled "generate debug information: Yes (-g cv8)", breakpoints do not work in asm file.
Used this to install yasm in VS2017:
https://github.com/ShiftMediaProject/VSYASM
asm file:
```
section .text
global _my_asmz
_my_asmz:
push ebp ; save base pointer
mov ebp, esp ; set up new base pointer
mov eax, [ebp+8] ; get first argument
add eax, 1 ; add 1 to it
mov esp, ebp ; restore stack pointer
pop ebp ; restore base pointer
ret ; return the value in eax
```
main.cpp:
```
#include <iostream>
extern "C" int my_asmz(int);
//using namespace std;
int main()
{
int x = 43;
int y = my_asmz(x);
std::cout << "x = " << x << ", y = " << y << std::endl;
std::system("pause");
return 0;
}
```
|
Does yasm integrated in VS2017 support breakpoint in mixed cpp and asm file?

hi!
* i am looking for some alternate to the Turbo Assembled (tasm)
* for doing the practical for the subject of MicroProcessors 8086 (so, i want to see the value of registers, flags, segments etc)
* using VSCodium or some dedicated IDE.
I found yasm via [alternativeto][yasm-alt2] & i have read the [yasm-site] but i can't find which one to use.
[yasm-site]: http://yasm.tortall.net
[yasm-alt2]: https://alternativeto.net/browse/search/?q=nasm#item-3949c529-0955-e211-9c6a-0025902c7e73

differences from nasm and which one to use?

The 1.3.0 release provides [yasm-1.3.0-win64.exe](http://www.tortall.net/projects/yasm/releases/yasm-1.3.0-win64.exe), which needs `MSVCRT100.dll`.
However, this dll is not installed by default on the Windows-2022 Github runners.
So it would be useful to, when a next release is done, to provide binaries that don't need any system C library.

Provide MSVC runtime-free binary releases

Hello Yasm developers,
We recently conducted a fuzzing test on yasm and discovered a heap-buffer-overflow bug. We would like to provide a detailed description of the bug and seek your assistance in addressing it.
version:
Yasm: 1.3.0
gcc:gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)
ubuntu: 20.04
command to reproduce:
yasm [HBO](https://github.com/shinibufa/crash_seeds/blob/main/yasm/HBO)

It seems that yasm's `-l` (listing) option does not include bytes for a `rep` prefix if the `rep` is on the same line as the affected `stos`.
## Steps to reproduce
Create `hello.S`:
```
.code64
rep ; stosq
```
Run:
```
$ yasm -p gas -L nasm -l hello.list hello.S
```
## Observed output
`hello.list`:
```
1 .code64
2 00000001 48AB rep ; stosq
3
```
`hello` (output file hex dump):
```
00000000 f3 48 ab |.H.|
```
Note that `F3` is missing from `hello.list`.
## Expected output
`hello.list`:
```
1 .code64
2 00000000 F348AB rep ; stosq
3
```
`hello` (output file hex dump):
```
00000000 f3 48 ab |.H.|
```
## More information
This bug does not happen if the `rep` and the `stos` are on separate lines:
```
.code64
rep
stosq
```
```
1 .code64
2 00000000 F3 rep
3 00000001 48AB stosq
4
```
I am using yasm version 1.3.0.

According to the NASM docs https://www.nasm.us/xdoc/2.15.05/html/nasmdoc3.html#section-3.4.2
> Strings enclosed in backquotes support C-style \–escapes for special characters.
This does not appear to be the case with yasm:
```nasm
; hello.asm
global _start
section .text
_start:
mov rax, 1
mov rdi, 1
mov rsi, message
mov rdx, messageLen
syscall
mov rax, 60
xor rdi, rdi
syscall
section .data
message db `Hello, World!\n`
messageLen equ $-message
```
`nasm -f elf64 hello.asm && ld hello.o && ./a.out` runs successfuly and prints `Hello, World!` (with a newline at the end)
`yasm -f elf64 hello.asm && ld hello.o && ./a.out` fails with the following log:
```
hello.asm:16: warning: ignoring unrecognized character ``'

Is there an extra flag that i need to pass for this feature to work, or is it just not supported in yasm? if the latter, i'd like to see the support for it added.

Add `TRASHIT()` macro to set pointer to NULL in `libyasm/compat-queue.h`.
This is just a hardening measure to make sure stale pointers are not left in next/prev struct members.
Also fixed here:

Hi,
When i used -f dosexe option, I found that yasm crashed.
<img width="437" alt="image" src="https://user-images.githubusercontent.com/39018042/172167231-dcb55bf1-3068-4697-ae50-15205868dac0.png">
Here is the command : ```./yasm -f dosexe ./poc```
My poc : https://gist.githubusercontent.com/naihsin/cc5318fd1f0655e60288eabeff6da930/raw/892829b7351a45eca138c30a071fc5d3736e5c2e/poc

I compiled the yasm code by these option
```
./autogen.sh; make distclean

error description:
when the argument is set to " -o . " (there are other effective conditions to crash when using with VS2022l)
the function "yasm__createpath(objdir_pathname)" returns 0xffffffff which is -1 as index,
objdir_pathname[i] = '/';
objdir_pathname[i + 1] = '\0';
will write the byte before objdir_pathname[0] and therefore cause crash while freeing this range of memory.
my solution:
if (((int)i) < 0) {
objdir_pathname[0] = '\0';
}
else
{
objdir_pathname[i] = '/';
objdir_pathname[i + 1] = '\0';
}

On this page:
https://en.wikipedia.org/wiki/Comparison_of_assemblers#x86-64_assemblers
Yasm is listed as "not in active development". This stopped me considering it until I went to github and saw that development is continuing. But I didn't want to change that status myself in case you're just maintaining?

It seems that immediate operands using characters are unsupported.
```
$ cat >| fuck.s
.globl main
main:
movb $'\n', %eax
ret
$ as -fatal-warnings -o /dev/null fuck.s
$ yasm -Werror -felf64 -pgas -o /dev/null fuck.s
: error: warnings being treated as errors
fuck.s:3: error: unexpected end of file in string
$ sed -i "s/'\\\\n'/10/" fuck.s
$ yasm -Werror -felf64 -pgas -o /dev/null fuck.s
: error: warnings being treated as errors
$
```
Is that due to the following code, or will I need to fiddle around with `parse_expr()`, `parse_operand()` and friends? Probably both, right?

Here is a small example of how I can reliably trigger it:
```c
#include <libyasm/bitvect.h>
#include <stdlib.h>
int main() {
wordptr v = BitVector_Create(64, 1);
BitVector_Destroy(v);
void* p = malloc(1024);
free(p);
return 0;
}
```
Running it gives me:
```
small.o: malloc.c:2539: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Aborted (core dumped)
```
I'm using: `gcc (SUSE Linux) 11.1.1 20210721 [revision 076930b9690ac3564638636f6b13bbb6bc608aea]` and `GNU C Library (GNU libc) release release version 2.33 (git 9826b03b74)`. I compiled libyasm myself with the same tools.
Upon exploring the sources I found out that when you create a bitvector with bitsize 64, it calculates the wrong word and byte sizes of 64 and 167 for it, and when you try to fill the vector, it overwrites heap structures causing heap corruption.

Regarding `UWOP_SET_FPREG`, according to https://docs.microsoft.com/en-us/cpp/build/exception-handling-x64?view=msvc-160:
> The operation info field is reserved and shouldn't be used.
But yasm appears to set it to the frame pointer register: https://github.com/yasm/yasm/blob/41762bead150fdae59687b35c8acd1c4ae0f1575/modules/objfmts/coff/coff-objfmt.c#L2078
It's an open question whether this is actually a problem! - I just noticed this while checking my own unwind data against yasm's output.

`endbr64` is a new psuedo-instruction (well, it's a real instruction on some CPUs that is) used for control flow information using what was previously a multibyte nop encoding:
`\xf3\x0f\x1e\xfa`
|
No support for endbr64 instruction

I built yasm with cmake on zsh and installed to a directory "/usr/local/git".
And I could find "/usr/local/git/bin/yasm" and "/usr/local/git/lib/libyasm.dylib".
I set the library path as "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/git/lib" in zshrc.
But yasm command cannot find libyasm.dylib. How can I fix it?
```
hoge@hoge % yasm
dyld: Library not loaded: libyasm.dylib
Referenced from: /usr/local/git/bin/yasm
Reason: image not found
zsh: abort yasm
hoge@hoge %
```

Hi guys,
Recently, I want to update yasm in vcpkg ([#12324](https://github.com/microsoft/vcpkg/pull/12324)) to solve some issues, but I got the error message on the pipeline machine:
```
D:\installed\x64-windows\share\vs-yasm\yasm.targets(50,5): error MSB3721: The command ""D:/downloads/tools/yasm/1.3.0.6/x64/"yasm.exe -Xvc -f win64 -o "D:\buildtrees\gmp\x64-windows-rel\adcc6b3cc4-2b6258d695.clean\SMP\obj\ReleaseDLL\x64\libgmp\addaddmul_1msb0.obj" -rraw -pgas "D:\buildtrees\gmp\x64-windows-rel\adcc6b3cc4-2b6258d695.clean\SMP\mpn\x86_64\addaddmul_1msb0.s"" exited with code -1073741515. [D:\buildtrees\gmp\x64-windows-rel\adcc6b3cc4-2b6258d695.clean\SMP\libgmp.vcxproj]
```
This command invokes symlink from other disks. If symlink is not used, this problem will not occur.
Anyone can solve this issue or give me some solutions?
Thanks.

Description: Access violation near NULL on source operand
Short description: SourceAvNearNull (16/22)
Explanation: The target crashed on an access violation at an address matching the source operand of the current instruction. This likely indicates a read access violation, which may mean the application crashed on a simple NULL dereference to data structure that has no immediate effect on control of the processor.

Extra Data:
Description: Heap error
Short description: HeapError (10/22)
Explanation: The target's backtrace indicates that libc has detected a heap error or that the target was executing a heap function when it stopped. This could be due to heap corruption, passing a bad pointer to a heap function such as free(), etc. Since heap errors might include buffer overflows, use-after-free situations, etc. they are generally considered exploitable.
