This allows emitting object files for s390x-zos (GOFF) and powerpc(64)-aix
(XCOFF).
Note that GOFF emission in LLVM is still being worked on upstream for LLVM 21;
the resulting object files are useless right now. Also, -fstrip is required, or
LLVM will SIGSEGV during DWARF emission.
* Accept -fsanitize-c=trap|full in addition to the existing form.
* Accept -f(no-)sanitize-trap=undefined in zig cc.
* Change type of std.Build.Module.sanitize_c to std.zig.SanitizeC.
* Add some missing Compilation.Config fields to the cache.
Closes#23216.
* This has not seen meaningful development for about a decade.
* The Linux kernel port was never upstreamed.
* The glibc port was never upstreamed.
* GCC 15.1 recently deprecated support it.
It may still make sense to support an ILP32 ABI on AArch64 more broadly (which
we already have the Abi.ilp32 tag for), but, to the extent that it even existed
in any "official" sense, the *GNU* ILP32 ABI is certainly dead.
This is fairly straightforward; the actual compiler changes are limited
to the CLI, since `Compilation` already supports this combination.
A new `std.Build` API is introduced to allow representing this. By
passing the `emit_object` option to `std.Build.addTest`, you get a
`Step.Compile` which emits an object file; you can then use that as you
would any other object, such as either installing it for external use,
or linking it into another step.
A standalone test is added to cover the build system API. It builds a
test into an object, and links it into a final executable, which it then
runs.
Using this build system mechanism prevents the build system from
noticing that you're running a `zig test`, so the build runner and test
runner do not communicate over stdio. However, that's okay, because the
real-world use cases for this feature don't want to do that anyway!
Resolves: #23374
Compile log output is now separated based on the `AnalUnit` which
perfomred the `@compileLog` call, so that we can omit the output for
unreferenced ("dead") units. The units are also sorted when collecting
the `ErrorBundle`, so that compile logs are always printed in a
consistent order, like compile errors are. This is important not only
for incremental compilation, but also for parallel analysis.
Resolves: #23609
* Fix compile error in Fuzzer web-ui
The error was:
```
error: expected type '?mem.Alignment', found 'comptime_int'
```
* Apply suggestions from code review
`.of` call is shorter and clearer

Closes#11909.
They are, themselves, static libraries even if the resulting artifact strictly
speaking requires dynamic linking to the corresponding system DLLs to run. Note,
though, that there's no libc-provided dynamic linker on Windows like on POSIX,
so this isn't particularly problematic.
This matches x86_64-w64-mingw32-gcc behavior.
