x86_64: liveness independent fixes
|
|
Native targets are, by definition, not cross-compiling targets.
|
|
Also reenable stage2_x86_64 windows behavior tests in case it is failing
for the same reason.
Closes #15324

* wasm32-wasi compiler_rt tests
* std lib tests with the C backend
|
|
The CI now runs C backend tests in addition to compiling them. It uses
-std=c99 -pedantic -Werror in order to catch non-conformant C code.
This necessitated disabling a test case that caused a C compile error,
in addition to disabling a handful of warnings that are already being
triggered by Zig's C backend output for the behavior tests.
The upshot is that I was able to, very cleanly, integrate the C backend
tests into the build system, so that it communicates via the test runner
protocol along with all the other behavior tests.
|
|
Make the test targets use options that match the actual options of
CompileStep. This makes the code more straightforward, and ends up
making fewer tests incorrectly skipped. For example, now the CI runner
on Windows will no longer skip self-hosted x86_64 backend tests.
|
|
* remove setName, setFilter, and setTestRunner. Please set these
options directly when creating the CompileStep.
* removed unused field
* remove computeOutFileNames and inline the logic, making clear the
goal of avoiding state mutations after the build step is created.
|
|
These functions are problematic in light of dependencies because they
run and install, respectively, for the *owner* package rather than for
the *user* package. By removing these functions, the build script is
forced to provide the *Build object to associate the new step with,
making everything less surprising.
Unfortunately, this is a widely breaking change.

It is reasonable to pass -Dskip-non-native when unable to run foreign
binaries, however there is no option for being able to run foreign
static binaries but unable to run foreign dynamic binaries. This can
occur when qemu is installed but not cross glibc.

std.Build.addTest creates a CompileStep as before, however, this kind of
step no longer actually runs the unit tests. Instead it only compiles
it, and one must additionally create a RunStep from the CompileStep in
order to actually run the tests.
RunStep gains integration with the default test runner, which now
supports the standard --listen=- argument in order to communicate over
stdin and stdout. It also reports test statistics; how many passed,
failed, and leaked, as well as directly associating the relevant stderr
with the particular test name that failed.
This separation of CompileStep and RunStep means that
`CompileStep.Kind.test_exe` is no longer needed, and therefore has been
removed in this commit.
* build runner: show unit test statistics in build summary
* added Step.writeManifest since many steps want to treat it as a
warning and emit the same message if it fails.
* RunStep: fixed error message that prints the failed command printing
the original argv and not the adjusted argv in case an interpreter
was used.
* RunStep: fixed not passing the command line arguments to the
interpreter.
* move src/Server.zig to std.zig.Server so that the default test runner
can use it.
* the simpler test runner function which is used by work-in-progress
backends now no longer prints to stderr, which is necessary in order
for the build runner to not print the stderr as a warning message.

Without this, aarch64-linux tried to compile this test for
aarch64-windows with the same CPU settings, which is not an intended
test combination.

Instead of using `zig test` to build a special version of the compiler
that runs all the test-cases, the zig build system is now used as much
as possible - all with the basic steps found in the standard library.
For incremental compilation tests (the ones that look like foo.0.zig,
foo.1.zig, foo.2.zig, etc.), a special version of the compiler is
compiled into a utility executable called "check-case" which checks
exactly one sequence of incremental updates in an independent
subprocess. Previously, all incremental and non-incremental test cases
were done in the same test runner process.
The compile error checking code is now simpler, but also a bit
rudimentary, and so it additionally makes sure that the actual compile
errors do not include *extra* messages, and it makes sure that the
actual compile errors output in the same order as expected. It is also
based on the "ends-with" property of each line rather than the previous
logic, which frankly I didn't want to touch with a ten-meter pole. The
compile error test cases have been updated to pass in light of these
differences.
Previously, 'error' mode with 0 compile errors was used to shoehorn in a
different kind of test-case - one that only checks if a piece of code
compiles without errors. Now there is a 'compile' mode of test-cases,
and 'error' must be only used when there are greater than 0 errors.
link test cases are updated to omit the target object format argument
when calling checkObject since that is no longer needed.
The test/stage2 directory is removed; the 2 files within are moved to be
directly in the test/ directory.

It's simpler and it takes advantage of
`std.Build.addAnonymousDependency`, which has a number of benefits,
including concurrenc and preventing extra zig-cache and zig-out
directories being created.
4 tests are ported over as an example.
|
|
These were mostly already using the correct build API. I cleaned up the
code a bit and unconditionally disabled LTO for these tests since that
actually tests the intended behavior better.
|
|
CLI tests are now ported over to the new std.Build API and thus work
properly with concurrency.
* add `std.Build.addCheckFile` for creating a
`std.Build.CheckFileStep`.
* add `std.Build.makeTempPath`. This function is intended to be called
in the `configure` phase only. It returns an absolute directory path,
which is potentially going to be a source of API breakage in the
future, so keep that in mind when using this function.
* add `std.Build.CheckFileStep.setName`.
* `std.Build.CheckFileStep`: better error message when reading the
input file fails.
* `std.Build.RunStep`: add a `has_side_effects` flag for when you need
to override the autodetection.
* `std.Build.RunStep`: add the ability to obtain a FileSource for the
directory that contains the written files.
* `std.Build.WriteFileStep`: add a way to write bytes to an arbitrary
path - absolute or relative to the package root. Be careful with this
because it updates source files. This should not be used as part of
the normal build process, but as a utility occasionally run by a
developer with intent to modify source files and then commit those
changes to version control. A file added this way is not available
with `getFileSource`.

* RunStep: ability to set stdin
* RunStep: ability to capture stdout and stderr as a FileSource
* RunStep: add setName method
* RunStep: hash the stdio checks

Rework std.Build.Step to have an `owner: *Build` field. This
simplified the implementation of installation steps, as well as provided
some much-needed common API for the new parallelized build system.
--verbose is now defined very concretely: it prints to stderr just
before spawning a child process.
Child process execution is updated to conform to the new
parallel-friendly make() function semantics.
DRY up the failWithCacheError handling code. It now integrates properly
with the step graph instead of incorrectly dumping to stderr and calling
process exit.
In the main CLI, fix `zig fmt` crash when there are no errors and stdin
is used.
Deleted steps:
* EmulatableRunStep - this entire thing can be removed in favor of a
flag added to std.Build.RunStep called `skip_foreign_checks`.
* LogStep - this doesn't really fit with a multi-threaded build runner
and is effectively superseded by the new build summary output.
build runner:
* add -fsummary and -fno-summary to override the default behavior,
which is to print a summary if any of the build steps fail.
* print the dep prefix when emitting error messages for steps.
std.Build.FmtStep:
* This step now supports exclude paths as well as a check flag.
* The check flag decides between two modes, modify mode, and check
mode. These can be used to update source files in place, or to fail
the build, respectively.
Zig's own build.zig:
* The `test-fmt` step will do all the `zig fmt` checking that we expect
to be done. Since the `test` step depends on this one, we can simply
remove the explicit call to `zig fmt` in the CI.
* The new `fmt` step will actually perform `zig fmt` and update source
files in place.
std.Build.RunStep:
* expose max_stdio_size is a field (previously an unchangeable
hard-coded value).
* rework the API. Instead of configuring each stream independently,
there is a `stdio` field where you can choose between
`infer_from_args`, `inherit`, or `check`. These determine whether the
RunStep is considered to have side-effects or not. The previous
field, `condition` is gone.
* when stdio mode is set to `check` there is a slice of any number of
checks to make, which include things like exit code, stderr matching,
or stdout matching.
* remove the ill-defined `print` field.
* when adding an output arg, it takes the opportunity to give itself a
better name.
* The flag `skip_foreign_checks` is added. If this is true, a RunStep
which is configured to check the output of the executed binary will
not fail the build if the binary cannot be executed due to being for
a foreign binary to the host system which is running the build graph.
Command-line arguments such as -fqemu and -fwasmtime may affect
whether a binary is detected as foreign, as well as system
configuration such as Rosetta (macOS) and binfmt_misc (Linux).
- This makes EmulatableRunStep no longer needed.
* Fix the child process handling to properly integrate with the new
bulid API and to avoid deadlocks in stdout/stderr streams by polling
if necessary.
std.Build.RemoveDirStep now uses the open build_root directory handle
instead of an absolute path.

Zig's build script has several race conditions preventing proper
concurrent builds from working. By using -j1 for now, finishing this
branch (concurrent zig builds) is untangled from the separate problem of
correcting concurrency issues with zig's own build script.
In other words, let's solve one problem at a time.
|
|
* Step.init() now takes an options struct
* Step.init() now captures a small stack trace and stores it in the
Step so that it can be accessed when printing user-friendly debugging
information, including the lines of code that created the step in
question.

|
|
|
|
|
|
* Use std.Build.Cache.Directory instead of a string for storing the
cache roots and build roots.
* Set up a std.Build.Cache in build_runner.zig and use it in
std.Build.RunStep for avoiding redundant work.

This regressed earlier in this branch.

This matches the nomenclature internally: a Compilation is the main type
that represents a single invokation of the compiler.

I've been wanting to do this for along time.

- add c_abi tests for .Stdcall
- enable (x86|x86_64)-windows-gnu in the c_abi tests
