This was originally introduced in 4d48948b526337947ef59a83f7dbc81b70aa5723
but broken immediately afterwards in c8af00c66e8b6f62e4dd6ac4d86a3de03e9ea354.
Before this commit, glibc headers did the following mapping:
* (zig) mipsel-linux-gnu => (glibc) mipsel-linux-gnu
* (zig) mipsel-linux-gnu-soft => (glibc) (none)
* (zig) mips-linux-gnu => (glibc) mips-linux-gnu
* (zig) mips-linux-gnu-soft => (glibc) (none)
While the glibc ABI stubs used the (zig) gnueabi and gnueabihf ABIs,
and the stage2 available_libcs array listed:
* (zig) mipsel-linux-gnu
* (zig) mips-linux-gnu
The problem is the mismatch between the ABI component of the headers and
the stubs.
This commit makes the following clarifications:
* (zig) mips-linux-gnueabi means soft-float
* (zig) mipsel-linux-gnueabi means soft-float
* (zig) mips-linux-gnueabihf means hard-float
* (zig) mipsel-linux-gnueabihf means hard-float
Consequently, the glibc headers now do this mapping:
* (zig) mips-linux-gnueabihf => (glibc) mips-linux-gnu
* (zig) mipsel-linux-gnueabihf => (glibc) mipsel-linux-gnu
* (zig) mips-linux-gnueabi => (glibc) mips-linux-gnu-soft
* (zig) mipsel-linux-gnueabi => (glibc) mipsel-linux-gnu-soft
The glibc ABI stubs are unchanged, and the stage2 available_libcs
array's 2 entries are modified and it gains 2 more:
* (zig) mipsel-linux-gnueabi
* (zig) mipsel-linux-gnueabihf
* (zig) mips-linux-gnueabi
* (zig) mips-linux-gnueabihf
Now everything is consistent. Zig no longer recognizes a `mips-linux-gnu`
triple; one must use `mips-linux-gnueabi` (soft float) or
`mips-linux-gnueabihf` (hard float).

This also modifies tools/update-linux-headers.zig to remove these same
files for next time to prevent a regression.
closes#10249
* Add missing Linux headers. Closes#9837
* Update existing headers to latest Linux.
* Consolidate headers that are the same for multiple Zig target CPU
architectures. For example, Linux has only an x86 directory for both
x86_64 and x86 CPU architectures. Now Zig only ships an x86 directory
for Linux headers, and will emit the proper corresponding -isystem
flags.
* tools/update-linux-headers.zig is now available for upgrading to
newer Linux headers, and the update process is now documented on the
wiki.
This commit also corrects a mistake from commit
6dc2236054dfcf911ce848f67a4078740a90783a which did not properly delete
files when upgrading to the 1.2.2 musl headers.
Rename include dir to match the convention:
from `wasm32-wasi` to `wasm-wasi-musl`
Add building stubs which will be used to build and cache WASI
libc sysroot.
The reason this is required is for two reasons: 1) the libc
targeting `aarch64` macOS is slightly newer than that targeting
`x86_64`, and 2) `OSAtomic.h` uses relative imports rather than
system-wide imports for accompanying headers which clearly is an
oversight on Apple's part. Until such time when `libkern` headers
between `x86_64` and `aarch64` are identical, this will require a
manual intervention to duplicate the relevant headers between the
respective architectures.
See #5854
Some tiny tweaks too:
* Use `wasm-freestanding-musl` instead of `wasm32-freestanding-musl`,
making it pointer-size-agnostic.
* Fix trying to build non-existent wasm musl start files.
See ziglang/fetch-them-macos-headers#2 for more details. The path
forward looks like one of the following:
* Ony provide headers for the oldest supported macOS (currently 10.13
but soon to be bumped to 10.14).
* Provide headers for multiple versions, and select based on the Zig
target OS version range minimum.
* Don't try to provide macOS headers.
If we don't tackle the version problem, we would have to re-introduce
the ability to detect and depend on native system headers if we wanted
to support C/C++ code that used newer OS definitions.
This patch also adds support for `#include <mach/mach_time.h>`.
Also related: #5236
these new files are generated by recursively including:
sysexits.h
mach/mach.h
sys/attr.h
sys/mount.h
crt_externs.h
execinfo.h
all of which are depended on by LLVM libraries.
This reverts commit bb9c3118ed5fdc16b8e2d9882375005c2a62d0cc, reversing
changes made to 7015d84e0ca6f02fede45621571084df98dda712.
This is missing quite a few headers
