* There was an edge case where the arena could be destroyed twice on
error: once from the arena itself and once from the decl destruction.
* The type of the created decl was incorrect (it should have been the
pointer child type), but it's not required anyway, so it's now just
initialized to anyopaque (which more accurately reflects what's
actually at that memory, since e.g. [*]T may correspond to nothing).
* A runtime bitcast of the pointer was performed, meaning @extern didn't
work at comptime. This is unnecessary: the decl_ref can just be
initialized with the correct pointer type.
Fixes#13970.
This fix makes test runners resolve package paths relative to the
directory the test runner is in. This means it is not possible to import
a file from outside the file tree root at the directory containing the
test runner.
This makes the following changes for i386:
long long and unsigned long long have 4 byte alignment on non-Windows
f64 (double) has 4-byte alignment on non-Windows
long double is 80 bits and has 4 byte alignment on mingw
long double on android is 64 bits, not 80: https://www.uclibc.org/docs/psABI-i386.pdfFixes#12453Fixes#12987
Extern functions were missing attributes such as "readonly" on
non-optional pointers, and "byval" which is required to match C ABI.

closes#12683
A self-defined macro is one of the form `#define FOO FOO`
Those types of macros have never been translated; this change will cause
any macros which refer to them to be translated as `@compileError` instead
of referring to a non-existent identifier.
Closes#12471
This reverts commit baead472d7641bdd96130354bafadc1fb1ed223b.
Let's go through the proposal process on this one. I want to push back
on this. My position is that, at the very least, a full trace of command
lines of sub-processes should be printed on failure, with the exception
of opt-in flags such as `--prominent-compile-errors`.
Address https://github.com/ziglang/zig/issues/3477
This provides a mechanism for builds to fully report an error to the user and prevent zig from piling on extra noise.
This commit introduces tools/update_glibc.zig to update the start files
for next time.
Some notable changes in recent glibc:
* abi-note.S has been changed to abi-note.c but we resist the change to
keep it easier to compile the start files.
* elf-init.c has been deleted upstream. Further testing should be done
to verify that binaries against glibc omitting elf-init.c still run
properly on oldel glibc linux systems.
Closes#4926
* add support for compiling Objective-C++ code
Prior to this change, calling `step.addCSourceFiles` with Obj-C++ file extensions
(`.mm`) would result in an error due to Zig not being aware of that extension.
Clang supports an `-ObjC++` compilation mode flag, but it was only possible to use
if you violated standards and renamed your `.mm` Obj-C++ files to `.m` (Obj-C) to
workaround Zig being unaware of the extension.
This change makes Zig aware of `.mm` files so they can be compiled, enabling compilation
of projects such as [Google's Dawn WebGPU](https://dawn.googlesource.com/dawn/) using
a `build.zig` file only.
