* CMakeLists: pass `-Dstrip` for release zig builds
* pass -target and -mcpu to zig1. works around llvm on freebsd
incorrectly detecting "freestanding" instead of "freebsd" for the
native OS.
* ci.ziglang.org is now responsible for creating aarch64-macos tarballs
rather than Azure.
* test/link: initial wasm support
This adds basic parsing and dumping of wasm section so they
can be tested using the new linker-test infrastructure.
* test/link: all wasm sections parsing and dumping
We now parse and dump all sections for the wasm binary format.
Currently, this only dumps the name of a custom section.
Later this should also dump symbol table, name, linking metadata and relocations.
All of those live within the custom sections.
* Add wasm linker test
This also fixes a parser mistake in reading the flags.
* test/link: implement linker tests wasm & fixes
Adds several test cases to test the wasm self-hosted linker.
This also introduces fixes that were caught during the implementation
of those tests.
* test-runner: obey omit_stage2 for standalone
When a standalone test requires stage2, but stage2 is omit
from the compiler, such test case will not be included as part
of the test suite that is being ran. This is to support CI's
where we omit stage2 to lower the memory usage.
Prior to this change we would assume the ABI for Apple targets to
be GNU which could result in subtle errors in LLVM emitting calls
to non-existent system libc provided functions such as `_sincosf`
which is a GNU extension and as such is not provided by macOS for example.
This would result in linker errors where the linker would not be
able to find the said symbol in `libSystem.tbd`.
With this change, we now correctly identify macOS (and other Apple
platforms) as having ABI `unknown` which translates to unspecified
in LLVM under-the-hood:
```
// main.ll
target triple = "aarch64-unknown-macos-unknown"
```
Note however that we never suffix the target OS with target version
such as `macos11` or `macos12` which means we fail to instruct LLVM
of potential optimisations provided by the OS such as the availability
of function `___sincosf_stret`. I suggest we investigate that in a
follow-up commit.
* migrate runtime safety tests to the new test harness
- this required adding compare output / execution support for stage1
to the test harness.
* rename `zig build test-stage2` to `zig build test-cases` since it now
does quite a bit of stage1 testing actually. I named it this way
since the main directory in the source tree associated with these
tests is "test/cases/".
* add some documentation for the test manifest format.
* Test everything on the Linux CI even if we can't run it, because it's
our fastest machine.
* Test stage2 using a build of stage2 (instead of using `-fno-stage1`)
so that compiler-rt is also built with stage2.
* Additionally test running x86_64-macos on the macOS CI, both the LLVM
backend and x86_64 backend.
Add additional search paths pointing at homebrew prefixes as Apple
doesn't ship a static libncurses for linking - only a stub for dynamic
linking `libncurses.tbd`.
NetBSD CI is disabled because it is not yet supported in
zig-bootstrap. Once NetBSD has proper zig-bootstrap support, it can be
re-enabled.
Windows is not solved here yet; will be pushing a separate commit for
that.
This way, we can explicitly signal if a test requires the presence
of macOS SDK to build. For instance, when testing our in-house
MachO linker for correctly linking Objective-C, we require the
presence of the SDK on the host system, and we can enforce this
with `-Denable-macos-sdk` flag to `zig build test-standalone`.
On CI, we have been running into OOM issues when running the test
suite on Windows for quite some time.
Unfortunately, we are very close to having the same issues on Linux
as well. Some additional comptime work immediately makes these builds
fail as well.
Add a new `test-toolchain` step, that tests everything except `std.*`
and documentation.
On CI, call `test-toolchain`, `test-std` and `docs` separately
instead of the `test` big hammer that emcompasses all of them.
Change the special case we made for Windows to the same code as other
platforms.
This is a stopgap measure that stage2 will eventually make useless.
Until then, it gives us some headroom.
Change `linux_script` by the way to only output the log of failing
steps. This shrinks the Linux CI log from a bazilion lines down to
something more humanely manageable.
