The new `--error-style` option decides how build failures are printed.
The default mode "verbose" prints all context including the step graph
fragment and the failed command (if any). The alternative mode "minimal"
prints only the failed step itself, and does not print the failed
command. There are also "verbose_clear" and "minimal_clear" modes, which
have the distinction that the output is cleared (through ANSI escape
codes) between updates, preventing different updates from being confused
in the output. If `--error-style` is not specified, the environment
variable `ZIG_BUILD_ERROR_STYLE` is checked before falling back to the
default of "verbose"; this means the value can effectively be chosen
system-wide since it is generally a personal preference.
Also introduced is a `--multiline-errors` option which decides how to
print errors which span multiple lines. By default, non-initial lines
are indented to align with the first. Alternatively, a leading newline
can be printed to align everyting on the first column, or no special
treatment can be applied, resulting in misaligned output. Again, there
is an environment variable (`ZIG_BUILD_MULTILINE_ERRORS`) to specify a
preferred default if the option is not explicitly provided.
Resolves: #23472
This is a major refactor to `Step.Run` which adds new functionality,
primarily to the execution of Zig tests.
* All tests are run, even if a test crashes. This happens through the
same mechanism as timeouts where the test processes is repeatedly
respawned as needed.
* The build status output is more precise. For each unit test, it
differentiates pass, skip, fail, crash, and timeout. Memory leaks are
reported separately, as they do not indicate a test's "status", but
are rather an additional property (a test with leaks may still pass!).
* The number of memory leaks is tracked and reported, both per-test and
for a whole `Run` step.
* Reporting is made clearer when a step is failed solely due to error
logs (`std.log.err`) where every unit test passed.
For now, there is a flag to `zig build` called `--test-timeout-ms` which
accepts a value in milliseconds. If the execution time of any individual
unit test exceeds that number of milliseconds, the test is terminated
and marked as timed out.
In the future, we may want to increase the granularity of this feature
by allowing timeouts to be specified per-step or even per-test. However,
a global option is actually very useful. In particular, it can be used
in CI scripts to ensure that no individual unit test exceeds some
reasonable limit (e.g. 60 seconds) without having to assign limits to
every individual test step in the build script.
Also, individual unit test durations are now shown in the time report
web interface -- this was fairly trivial to add since we're timing tests
(to check for timeouts) anyway.
This commit makes progress on #19821, but does not close it, because
that proposal includes a more sophisticated mechanism for setting
timeouts.

This is very likely full of wrong stuff. It's effectively just a copy of the
x86_64 file - needed because the former stopped using usize/isize. To be clear,
this is no more broken than the old situation was; this just makes the
brokenness explicit.

This reverts commit fcfdf99122b17a928c144c3d70418b35e6b1620e.
This added too much load to the x86_64-linux machines, resulting in timeouts
pretty much across the board.
This is a rewrite of the BLAKE3 implementation, with vectorization.
On Apple Silicon, the new implementation is about twice as fast as the previous one.
With AVX2, it is more than 4 times faster.
With AVX512, it is more than 7.5x faster than the previous implementation (from 678 MB/s to 5086 MB/s).
The return address points to the call instruction on SPARC, so the actual return
address is 8 bytes after. This means that we shouldn't do the return address
adjustment that we normally do.
The FP would point to the register save area for the previous frame, while the
SP points to the register save area for the current frame. So use the latter.
I have no idea if this is a QEMU bug or real kernel behavior. Either way, the
register save area specifically exists for asynchronous spilling of incoming and
local registers, so there should be no harm in doing this.
