Introduces `disable_zig_progress` which prevents the build runner from
assigning the child process a progress node.
This is needed for the empty_env test which requires the environment to
be completely empty.
You don't know if it's possible to run a binary until you try. The build
system already integrates with executors and has the
`skip_foreign_checks` for exactly this use case.
This reverts commit a7de02e052.
This did not implement the accepted proposal, and I did not sign off
on the changes. I would like a chance to review this, please.
Fixes regression introduced by 5d5e89aa8d
Turns out since landing that PR we haven't run any tests requiring
symlinks or any Apple SDK on a macOS host. Not great.
Previously the error had a note suggesting to use `try`, `catch`, or
`if`, even for error sets where none of those work.
Instead, in case of an error set the way you can handle the error
depends very much on the specific case. For example you might be in a
`catch` where you are discarding or ignoring the error set capture
value, in which case one way to handle the error might be to `return`
the error.
So, in that case, we do not attach that error note.
Additionally, this makes the error tell you what kind of an error it is:
is it an error set or an error union? This distinction is very relevant
in how to handle the error.
Maybe I'm just being pedantic here (most likely) but I don't like how we're
just telling the user here how to "suppress this error" by "assigning the value to '_'".
I think it's better if we use the word "discard" here which I think is
the official terminology and also tells the user what it actually means
to "assign the value to '_'".
Also, using the value would also be a way to "suppress the error".
It is just one of the two options: discard or use.
this one is even harder to document then the last large overhaul.
TLDR;
- split apart Emit.zig into an Emit.zig and a Lower.zig
- created seperate files for the encoding, and now adding a new instruction
is as simple as just adding it to a couple of switch statements and providing the encoding.
- relocs are handled in a more sane maner, and we have a clear defining boundary between
lea_symbol and load_symbol now.
- a lot of different abstractions for things like the stack, memory, registers, and others.
- we're using x86_64's FrameIndex now, which simplifies a lot of the tougher design process.
- a lot more that I don't have the energy to document. at this point, just read the commit itself :p
LLVMABIAlignmentOfType(i128) reports 16 on this target, however the C
ABI uses align(4).
Clang in LLVM 17 does this:
%struct.foo = type { i32, i128 }
Clang in LLVM 18 does this:
%struct.foo = type <{ i32, i128 }>
Clang is working around the 16-byte alignment to use align(4) for the C
ABI by making the LLVM struct packed.
This allows running commands that take an output directory argument. The
main thing that was needed for this feature was generated file subpaths,
to allow access to the files in a generated directory. Additionally, a
minor change was required to so that the correct directory is created
for output directory args.
* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
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
