The added comment explains the issue here relatively well. The new
progress API made this bug obvious because it became visibly clear that
certain Compile steps were seemingly "hanging" until other steps
completed. As it turned out, these child processes had raced to spawn,
and hence one had inherited the other's stdio pipes, meaning the `poll`
call in `std.Build.Step.evalZigProcess` was not identifying the child
stdout as closed until an unrelated process terminated.
This was a "fake" type used to handle C varargs parameters, much like
generic poison. In fact, it is treated identically to generic poison in
all cases other than one (the final coercion of a call argument), which
is trivially special-cased. Thus, it makes sense to remove this special
tag and instead use `generic_poison_type` in its place. This fixes
several bugs in Sema related to missing handling of this tag.
Resolves: #19781
Adds an `include_paths` field to RcSourceFile that takes a slice of LazyPaths. The paths are resolved and subsequently appended to the -rcflags as `/I <resolved path>`.
This fixes an accidental regression from https://github.com/ziglang/zig/pull/19174. Before that PR, all Win32 resource compilation would inherit the CC flags (via `addCCArgs`), which included things like include directories. After that PR, though, that is no longer the case.
However, this commit intentionally does not restore the previous behavior (inheriting the C include paths). Instead, each .rc file will need to have its include paths specified directly and the include paths only apply to one particular resource script. This allows more fine-grained control and has less potentially surprising behavior (at the cost of some convenience).
Closes#19605
This function incorrectly assumed that module name subsections, function
name subsections, and local name subsections are encoded the same,
however according to
[the specification](https://webassembly.github.io/spec/core/appendix/custom.html)
they are encoded differently.
This commit adds support for parsing module name subsections correctly,
which started appearing after upgrading to LLVM 18.
As of Clang 18, calling memcpy() with a misaligned pointer trips UBSAN,
even if the length is zero. This unfortunately includes any call to
`@memcpy` when source or destination are undefined and the length is
zero.
This patch makes the C backend avoid calling memcpy when the length is
zero, thereby avoiding undefined behavior.
A zig1.wasm update will be needed in the llvm18 branch to activate this
code.
wheras on NetBSD, only 2 PT_LOAD are usually produced by other compilers
(tested with host gcc and clang).

* Fix the ELF binaries for freestanding target created with the self-hosted linker.
The ELF specification (generic ABI) states that ``loadable process segments must have congruent
values for p_vaddr and p_offset, modulo the page size''. Linux refuses to load binaries that
don't meet this requirement (execve() fails with EINVAL).
A volume can be mounted as a NTFS path, e.g. as C:\Mnt\Foo. In that case, IOCTL_MOUNTMGR_QUERY_POINTS gives us a mount point with a symlink value something like `\??\Volume{383da0b0-717f-41b6-8c36-00500992b58d}`. In order to get the `C:\Mnt\Foo` path, we can query the mountmgr again using IOCTL_MOUNTMGR_QUERY_DOS_VOLUME_PATH.
Fixes#19731
* Adjust buffer length a bit.
* Fix detecting if file is a script. Logic below was unreachable,
because 99% of scripts failed "At least 255 bytes long" check and were detected as ELF files.
It should be "At least 4" instead (minimum value of "ELF magic length" and "smallest possible interpreter path length").
* Fix parsing interpreter path, when text after shebang:
1. does not have newline,
2. has leading spaces and tabs,
3. separates interpreter and arguments by tab or NUL.
* Remove empty error set from `defaultAbiAndDynamicLinker`.
