This does not completely ignore static asserts - they are validated by aro
during parsing; any failures will render an error and non-zero exit code.
Emit a warning comment that _Static_asserts are not translated - this
matches the behavior of the existing clang-based translate-c.
Aro currently does not store source locations for _Static_assert
declarations so I've hard-coded token index 0 for now.
The core functionalities are now in two general functions
`extremeInSubtreeOnDirection()` and `nextOnDirection()` so all the other
traversing functions (`getMin()`, `getMax()`, and `InorderIterator`) are
all just trivial calls to these core functions.
The added two functions `Node.next()` and `Node.prev()` are also just
trivial calls to these.
* std.Treap traversal direction: use u1 instead of usize.
* Treap: fix getMin() and getMax(), and add tests for them.
This is a misfeature that we inherited from LLVM:
* https://reviews.llvm.org/D61259
* https://reviews.llvm.org/D61939
(`aarch64_32` and `arm64_32` are equivalent.)
I truly have no idea why this triple passed review in LLVM. It is, to date, the
*only* tag in the architecture component that is not, in fact, an architecture.
In reality, it is just an ILP32 ABI for AArch64 (*not* AArch32).
The triples that use `aarch64_32` look like `aarch64_32-apple-watchos`. Yes,
that triple is exactly what you think; it has no ABI component. They really,
seriously did this.
Since only Apple could come up with silliness like this, it should come as no
surprise that no one else uses `aarch64_32`. Later on, a GNU ILP32 ABI for
AArch64 was developed, and support was added to LLVM:
* https://reviews.llvm.org/D94143
* https://reviews.llvm.org/D104931
Here, sanity seems to have prevailed, and a triple using this ABI looks like
`aarch64-linux-gnu_ilp32` as you would expect.
As can be seen from the diffs in this commit, there was plenty of confusion
throughout the Zig codebase about what exactly `aarch64_32` was. So let's just
remove it. In its place, we'll use `aarch64-watchos-ilp32`,
`aarch64-linux-gnuilp32`, and so on. We'll then translate these appropriately
when talking to LLVM. Hence, this commit adds the `ilp32` ABI tag (we already
have `gnuilp32`).
The flag makes compiler_rt and libfuzzer be in debug mode.
Also:
* fuzzer: override debug logs and disable debug logs for frequently
called functions
* std.Build.Fuzz: fix bug of rerunning the old unit test binary
* report errors from rebuilding the unit tests better
* link.Elf: additionally add tsan lib and fuzzer lib to the hash
This flag makes the build runner rebuild unit tests after the pipeline
finishes, if it finds any unit tests.
I did not make this integrate with file system watching yet.
The test runner is updated to detect which tests are fuzz tests.
Run step is updated to track which test indexes are fuzz tests.
This was added as an architecture to LLVM's target triple parser and the Clang
driver in 2015. No backend ever materialized as far as I can see (same for GCC).
In 2016, other code referring to it started using "Myriad" instead. Ultimately,
all code related to it that isn't in the target triple parser was removed. It
seems to be a real product, just... literally no one seems to know anything
about the ISA. I figure after almost a decade with no public ISA documentation
to speak of, and no LLVM backend to reference, it's probably safe to assume that
we're not going to learn much about this ISA, making it useless for Zig.

This was used for LoongArch64, where:
* `gnuf64` -> `ilp32d` / `lp64d` (full hard float)
* `gnuf32` -> `ilp32f` / `lp64f` (hard float for `f32` only)
* `gnusf` -> `ilp32` / `lp64` (soft float)
But Loongson eventually settled on just `gnu` for the first case since that's
what most people will actually be targeting outside embedded scenarios. The
`gnuf32` and `gnusf` specifiers remain in use.
Remove --debug-incremental
This flag is also added to the build system. Importantly, this tells
Compile step whether or not to keep the compiler running between
rebuilds. It defaults off because it is currently crashing
zirUpdateRefs.
Changes the `make` function signature to take an options struct, which
additionally includes `watch: bool`. I intentionally am not exposing
this information to configure phase logic.
Also adds global zig cache to the compiler cache prefixes.
Closes#20600
Makes the build runner compile successfully for non-linux targets;
printing an error if you ask for --watch rather than making build
scripts fail to compile.
Updates the build runner to unconditionally require a zig lib directory
parameter. This parameter is needed in order to correctly understand
file system inputs from zig compiler subprocesses, since they will refer
to "the zig lib directory", and the build runner needs to place file
system watches on directories in there.
The build runner's fanotify file watching implementation now accounts
for when two or more Cache.Path instances compare unequal but ultimately
refer to the same directory in the file system.
Breaking change: std.Build no longer has a zig_lib_dir field. Instead,
there is the Graph zig_lib_directory field, and individual Compile steps
can still have their zig lib directories overridden. I think this is
unlikely to break anyone's build in practice.
The compiler now sends a "file_system_inputs" message to the build
runner which shares the full set of files that were added to the cache
system with the build system, so that the build runner can watch
properly and redo the Compile step. This is implemented for whole cache
mode but not yet for incremental cache mode.
