to avoid getting OOM killed. It's been happening regularly recently. We
need to have a high number of GitHub Actions runners simultaneously
active, otherwise the hardware ends up underutilized. But with zig build
running in parallel now, this sometimes results in memory usage spikes
that have been causing the runner to get killed.
This number is the total physical memory (126G) divided by the number of
runners we have active (6).
This reverts commit a34752c941.
With #15277 merged, the macOS CI will still run the self-hosted x86_64
tests even with -Dskip-non-native. This was the main motivation for the
commit.
It would be nice to keep this flag enabled, however, we don't have
enough CI computing power, and the macOS CI lags behind with these extra
tests enabled.
I find myself quite often creating ReleaseSafe builds and putting them
to production for certain experiments:
- Debug info are for stack traces. An ongoing example where those would
help is #14815.
- Safety checks would have saved a couple of mine and @kubkon's hours in
#15098.
This is a breaking change for scripts that make Zig releases -- I will
submit another PR to zig-bootstrap and release-cutter after this is
merged.
Zig's build script has several race conditions preventing proper
concurrent builds from working. By using -j1 for now, finishing this
branch (concurrent zig builds) is untangled from the separate problem of
correcting concurrency issues with zig's own build script.
In other words, let's solve one problem at a time.
- cbe: Implement linksection support, to support TLS when not linking libc
- cbe: Support under-aligned variables / struct fields
- cbe: Support packed structs (in the C definition of packed)
- windows: Fix regression with x86 _tls_array
- compiler_rt: Add 128-bit atomics to compiler_rt
- tests: Re-enable threadlocal tests on cbe+windows, and llvm+x86
- tests: Re-enable f80 tests that now pass
- ci: change windows ci to run the CBE behaviour tests with -lc, to match how the compiler is bootstrapped
- update zig1.wasm
This allows using `zig ar` for `CMAKE_AR`. Unfortunately, it requires a
patch to CMakeLists.txt and cannot be done merely with flags to the
cmake line.
I messed up the spelling of '-stack_size' making it '-stack' instead.
Will need to fix on master branch. But let's test this here before
making another master branch commit.
In particular, these two changes are relevant:
* zig cc: support -stack in addition to --stack for linker arg
- Fixes stack overflow when running zig2 on aarch64-macos.
* compiler_rt: avoid using weak aliases
- Fixes duplicate symbol when linking zig2 on aarch64-linux.
In the CI system, I copied the old tarball and then applied
05c21a26cb2d5daf06191bd996d0770192704b66 to its compiler_rt
implementation.
After this is verified we can drop this commit and regenerate the
tarballs from a master branch commit.
Override the cache directories because they won't actually help other CI
runs which will be testing alternate versions of zig, and ultimately
would just fill up space on the hard drive for no reason.
In practice we did see one of the CI servers fill up too many files
inside ~/.cache/zig, which caused certain file system operations to
start returning ENOSPC, despite the hard drive having plenty of space
left.
