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.
