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.
new pipeline `BuildMacOS_arm64`
- `vmImage: 'macOS-10.15' `
new `macos_arm64_script`
- switch from using `make` to `ninja`
- select xcode 12.4
- set zig-cache env variables
- build host-zig binary with xcode, link against llvm for x86_64 (target macos 10.15)
- build arm64-zig binary with xcode and host-zig, link against llvm for arm64 (target macos 11.0)
- ad-hoc codesign arm64 binary with linker
- use host-zig for docgen
- use host-zig for experimental std lib docs
- sync final `release/` hierarchy with `linux_script`
- use gnu-tar for good-practices (set owner, set sort)
enhance `CMakeLists.txt`
- do not build `zig0` when cross-compiling
- disable `BYPRODUCTS` directive `zig1.o` to avoid `ninja` error
see #8265
I got this error when re-running the cmake line setting
-DZIG_EXECUTABLE:
```
ninja: warning: multiple rules generate zig1.o. builds involving
this target will not be correct; continuing anyway
[-w dupbuild=warn]
```
But it works fine with make.
* no longer depend on apt.llvm.org, instead we rely on a zig-bootstrap
tarball with pre-built Zig, LLVM, LLD, and Clang. Similar to the
Windows Dev Kit but for Linux. This also makes the script no longer
depend on Docker, libxml2, or GCC.
* remove bash retry logic; it was only needed for flaky apt.llvm.org
and isn't needed for the other resources we download.
* build and upload the experimental std lib automatically generated
docs. langref.html is moved to docs/langref.html because the std lib
docs are in docs/std/.
* the superfluous "zig" directory in $prefix/lib/zig/std/std.zig is
removed from the tarball.
* update_download_page makes a commit in the www.ziglang.org repository
updating data/releases.json so that repository can manage deploys.
