* add zig build option `-Dskip-libc` to skip tests that build libc
(e.g. if you don't want to wait for musl to build)
* add `-Denable-wine` option which uses wine to run cross compiled
windows tests on non-windows hosts
* add `-Denable-qemu` option which uses qemu to run cross compiled
foreign architecture tests
* add `-Denable-foreign-glibc=path` option which combined with
`-Denable-qemu` enables running cross compiled tests that link
against glibc. See
https://github.com/ziglang/zig/wiki/Updating-libc#glibc for how to
produce this directory.
* the test matrix is done manually. release test builds are only
enabled by default for the native target. this should save us some CI
time, while still providing decent coverage of release builds.
- add test coverage for `x86_64-linux-musl -lc` (building musl libc)
- add test coverage for `x86_64-linux-gnu -lc` (building glibc)
- add test coverage for `aarch64v8_5a-linux-none`
- add test coverage for `aarch64v8_5a-linux-musl -lc` (building musl libc)
- add test coverage for `aarch64v8_5a-linux-gnu -lc` (building glibc)
- add test coverage for `arm-linux-none`
- test coverage for `arm-linux-musleabihf -lc` (building musl libc) is
disabled due to #3286
- test coverage for `arm-linux-gnueabihf -lc` (building glibc) is disabled
due to #3287
- test coverage for `x86_64-windows-gnu -lc` (building mingw-w64) is
disabled due to #3285
* enable qemu testing on the Linux CI job. There's not really a good
reason to enable wine, since we have a Windows CI job as well.
* remove the no longer needed `--build-file ../build.zig` from CI
scripts
* fix bug in glibc compilation where it wasn't properly reading the abi
list txt files, resulting in "key not found" error.
* std.build.Target gains:
- isNetBSD
- isLinux
- osRequiresLibC
- getArchPtrBitWidth
- getExternalExecutor
* zig build system gains support for enabling wine and enabling qemu.
`artifact.enable_wine = true;`, `artifact.enable_qemu = true;`. This
communicates that the system has these tools installed and the build
system will use them to run tests.
* zig build system gains support for overriding the dynamic linker of
an executable artifact.
* fix std.c.lseek prototype. makes behavior tests for
arm-linux-musleabihf pass.
* disable std lib tests that are failing on ARM. See #3288, #3289
* provide `std.os.off_t`.
* disable some of the compiler_rt symbols for arm 32 bit. Fixes
compiler_rt tests for arm 32 bit
* add __stack_chk_guard when linking against glibc. Fixes std lib tests
for aarch64-linux-gnu
* workaround for "unable to inline function" using `@inlineCall`. Fixes
compiler_rt tests for arm 32 bit.
* Reuse bytes of async function frames when non-async functions
make `noasync` calls. This prevents explosive stack growth.
* Zig now passes a stack size argument to the linker when linking ELF
binaries. Linux ignores this value, but it is available as a program
header called GNU_STACK. I prototyped some code that memory maps
extra space to the stack using this program header, but there was
still a problem when accessing stack memory very far down. Stack
probing is needed or not working or something. I also prototyped
using `@newStackCall` to call main and that does work around the
issue but it also brings its own issues. That code is commented out
for now in std/special/start.zig. I'm on a plane with no Internet,
but I plan to consult with the musl community for advice when I get a
chance.
* Added `noasync` to a bunch of function calls in std.debug. It's very
messy but it's a workaround that makes stack traces functional with
evented I/O enabled. Eventually these will be cleaned up as the root
bugs are found and fixed. Programs built in blocking mode are
unaffected.
* Lowered the default stack size of std.io.InStream (for the async
version) to 1 MiB instead of 4. Until we figure out how to get
choosing a stack size working (see 2nd bullet point above), 4 MiB
tends to cause segfaults due to stack size running out, or usage of
stack memory too far apart, or something like that.
* Default thread stack size is bumped from 8 MiB to 16 to match the
size we give for the main thread. It's planned to eventually remove
this hard coded value and have Zig able to determine this value
during semantic analysis, with call graph analysis and function
pointer annotations and extern function annotations.
- Replace @intCast with a checked version (std/debug.zig)
- Replace @intCast with i64() when casting from a smaller type (std/fs/file.zig)
- Replace `nakedcc` with appropriate calling convention for linking with c (std/os/linux/arm-eabi.zig)
- Only check if hwcap contains TLS when the hwcap field actually exists (std/os/linux/tls.zig)
This reverts commit ec7d7a5b14540ea3b2bab9f11318630338467965, reversing
changes made to 81c441f8855d4c58f0b2ff86d3d007cf0bf395d3.
It looks like this broke colors in Windows Command Prompt (#3147)
and this method of detecting native C ABI isn't working well (#3121).
- Use sys_*stat*64 instead of sys_*stat* where appropriate
- Fix overflow when calculating atime, ctime and mtime on File.stat()
- Fix compilation error casting getEndPos to usize.
