This fixes a bug where, at least with the LLVM backend, `@extern` calls
which had the same name as a normal `extern` in the same Zcu would
result in the `@extern` incorrectly suffixing the identifier `.2`.
Usually, the LLVM backend has a system to change the generated globals
to "collapse" them all together, but it only works if `updateDecl` is
called!
This commit adds several fixes and improvements for the Zig compiler
test harness.
1. -Dskip-translate-c option added for skipping the translate-c tests.
2. translate-c/run-translated-c tests in test/cases/* have been added to
the steps test-translate-c and test-run-translated-c. Closes#18224.
3. Custom name added to the CheckFile step for the translate-c step to
better communicate which test failed.
4. Test manifest key validation added to return an error if a manifest
contains an invalid key.
* `linux.IO_Uring` -> `linux.IoUring` to align with naming conventions.
* All functions `io_uring_prep_foo` are now methods `prep_foo` on `io_uring_sqe`, which is in a file of its own.
* `SubmissionQueue` and `CompletionQueue` are namespaced under `IoUring`.
This is a breaking change.
The new file and namespace layouts are more idiomatic, and allow us to
eliminate one more usage of `usingnamespace` from the standard library.
2 remain.
Some of the structs I shuffled around might be better namespaced under
CONTEXT, I'm not sure. However, for now, this approach preserves
backwards compatibility.
Eliminates one more usage of `usingnamespace` from the standard library.
3 remain.
Thanks to Zig's lazy analysis, it's fine for these symbols to be
declared on platform they won't exist on. This is already done in
several places in this file; e.g. `pthread` functions are declared
unconditionally.
Eliminates one more usage of `usingnamespace` from the standard library.
4 remain.
Searching GitHub indicated that the only use of these types in the wild is
support in getty-zig, and testing for that support. This eliminates 3 more uses
of usingnamespace from the standard library, and removes some unnecessarily
complex generic code.
This usage of `usingnamespace` was removed fairly trivially - the
resulting code is, IMO, more clear.
Eliminates one more usage of `usingnamespace` from the standard library.
This is a trivial change - this code did `usingnamespace` into an
otherwise empty namespace, so the outer namespace was just unnecessary.
Eliminates one more usage of `usingnamespace` from the standard library.
Previously, when multiple modules had builtin modules with identical
sources, two distinct `Module`s and `File`s were created pointing at the
same file path. This led to a bug later in the frontend. These modules
are now deduplicated with a simple hashmap on the builtin source.
This fixes an issue with the implementation of #18816. Consider the
following code:
```zig
pub fn Wrap(comptime T: type) type {
return struct {
pub const T1 = T;
inner: struct { x: T1 },
};
}
```
Previously, the type of `inner` was not considered to be "capturing" any
value, as `T1` is a decl. However, since it is declared within a generic
function, this decl reference depends on the context, and thus should be
treated as a capture.
AstGen has been augmented to tunnel references to decls through closure
when the decl was declared in a potentially-generic context (i.e. within
a function).
