67d5bfef removed std.ChildProcess tests, suggesting to make them
standalone instead. This commit does exactly that after the
bug creating SIGPIPE in ReleaseFast is no more with LLVM 15.0.5.
Thanks to @x1ddos for the idea with the compile artifacts and PR
improvements.
This adds a standalone test case to ensure the runtime does not trap
when performing a memory.copy or memory.fill instruction while the
destination or source address is out-of-bounds and the length is 0.
* use the same hash function as the rest of the steps
* fix race condition due to a macOS oddity.
* fix race condition due to file truncation (rename into place instead)
* integrate with marking Step.result_cached. check if the file already
exists with fs.access before doing anything else.
* use a directory so that the file basename can be "options.zig"
instead of a hash digest.
* better error reporting in case of file system failures.
This test has a few problems:
* I don't want to vendor third party projects into the main compiler
repository such as kuba-zip just for test cases. If we want to test
third party projects, that should be a separate repository dedicated
to that purpose.
* Ideally tests would be isolated to test a particular thing, rather
than have a lot of unrelated logic that is not what is primarily
being tested.
* Ideally tests will not be named after GitHub issues, but named after
the thing that is being tested. And not testing for the absence of a
bug, but for the existence of correct behavior.
Aside from these issues, it's also failing in the LLVM 16 branch:
```
kuba-zip/zip.c:276:16: error: call to undeclared function 'fileno'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
kuba-zip/zip.c:277:14: error: call to undeclared function 'ftruncate'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
kuba-zip/zip.c:364:11: error: call to undeclared function 'symlink'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
```
These are not interesting failures related to the thing actually being
tested; this is busywork related to the fact that we vendor third party
code. So, that is why I chose to delete this test case instead of repair
it.
This was from master branch commit
c93e0d86187cb589d6726acd36f741f3d87a96be. Since standalone test are
completely reworked, I had to resolve the merge conflict later, in this
commit.
* There was an edge case where the arena could be destroyed twice on
error: once from the arena itself and once from the decl destruction.
* The type of the created decl was incorrect (it should have been the
pointer child type), but it's not required anyway, so it's now just
initialized to anyopaque (which more accurately reflects what's
actually at that memory, since e.g. [*]T may correspond to nothing).
* A runtime bitcast of the pointer was performed, meaning @extern didn't
work at comptime. This is unnecessary: the decl_ref can just be
initialized with the correct pointer type.
Fixes#13970.
This fix makes test runners resolve package paths relative to the
directory the test runner is in. This means it is not possible to import
a file from outside the file tree root at the directory containing the
test runner.
This makes the following changes for i386:
long long and unsigned long long have 4 byte alignment on non-Windows
f64 (double) has 4-byte alignment on non-Windows
long double is 80 bits and has 4 byte alignment on mingw
long double on android is 64 bits, not 80: https://www.uclibc.org/docs/psABI-i386.pdfFixes#12453Fixes#12987
Extern functions were missing attributes such as "readonly" on
non-optional pointers, and "byval" which is required to match C ABI.

closes#12683
A self-defined macro is one of the form `#define FOO FOO`
Those types of macros have never been translated; this change will cause
any macros which refer to them to be translated as `@compileError` instead
of referring to a non-existent identifier.
Closes#12471
