This requires using -Dstatic-llvm and setting the search prefix and the
target, just like it is required for building stage2 and stage3. This
prevents Zig from trying to integrate with the system, which would
trigger an error due to the `cc` command not being installed.
closes#12144
* Use a debug build of stage3 instead of a debug build of stage2 for
our self-hosted compiler test coverage.
* Move coverage from stage1 to stage3 for:
- building self-hosted without LLVM
- building self-hosted for 32-bit arm
- test-compiler-rt
- test-behavior
- test-std
- test-compare-output
- test-asm-link
- test-fmt
* 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.
stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"
We can't yet run the behavior tests with stage3, but at least we can run
them with stage2, and we can use the proper test matrix.
This commit also adds use_llvm and ofmt to the zig build system.
This change adds a "--exclude" parameter to zig format, which can be
used to make sure that it does not process certain files or folders
when recursively walking a directory.
To do this, we simply piggy-back on the existing "seen" logic in zig
fmt and mark these files/folders as seen before processing begins.
using the provided -L directories before checking if we need to integrate
with system library paths. This prevents false positive of invoking
system cc to find native paths when in fact all dependencies are
satisfied by -L (or --search-prefix to zig build).
* build.zig: remove detour through zig0. I'll add it back as an option
later. This means you can build stage1 with a freshly built zig
without detouring through zig0 again.
* remove unused file windows_script.bat
* drone.yml: remove unnecessary steps
* ninja doesn't need a jobs parameter
* build the release version of zig with zig build instead of cmake.
* build stage2 with -Dstatic-llvm -Duse-zig-libcxx
* 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.
- Correctly load slice value on stack
- Implement WrapErrorUnionErr and payload
- Implement trunc, fix sliceLen and write undefined
- Implement slice as return type and argument
Note: This also fixes a memory leak for inferred error sets, and for usingnamespace
This reverts commit 725267f7c2, reversing
changes made to 2dae860de3.
This test is failing:
```zig
pub fn main() u8 {
var e = foo();
const i = e catch 69;
return i;
}
fn foo() anyerror!u8 {
return 5;
}
```
It's returning 69 instead of the expected value 5.
from zig-specific options to generally recognized zig build options that
any project can take advantage of. See the updated usage text for more
details.
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`.
A new zsf-hosted server is being brought online.
This should be enough for linux build, test and packaging pipeline.
Currently this pipeline does not not post artifacts.
Upstream LLVM fixes#8597, no longer need `-Dskip-debug` and others.
Additionally, due to the nature of drone.io server pool, it is
beneficial to know which aarch64 CPU brand is in use.
- drop `-Dskip-debug` and others
- invoke `lscpu` prior to build
- enable more testsuite consistent with ci azure
- remove workaround for (already closed) #6830closes#8597
