Instead of `zig init-lib` and `zig init-exe`, now there is only
`zig init`, which initializes any of the template files that do not
already exist, and makes a package that contains both an executable and
a static library. The idea is that the user can delete whatever they
don't want. In fact, I think even more things should be added to the
build.zig template.
* 128-bit integer multiplication with overflow
* more instruction encodings used by std inline asm
* implement the `try_ptr` air instruction
* follow correct stack frame abi
* enable full panic handler
* enable stack traces
This reverts commit 0c99ba1eab63865592bb084feb271cd4e4b0357e, reversing
changes made to 5f92b070bf284f1493b1b5d433dd3adde2f46727.
This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.
I have observed the standard library tests overflowing the default WASI
stack as of the previous commit. As best as I can tell, this isn't
directly our fault: LLVM is just emitting less efficient code in debug
builds with the new codegen patterns.
After fixing some issues with inline assembly in the C backend, the std
cleanups have the side effect of making these functions compatible with
the backend, allowing it to be used on linux without linking libc.
* introduce LazyPath.cwd_relative variant and use it for --zig-lib-dir. closes#12685
* move overrideZigLibDir and setMainPkgPath to options fields set once
and then never mutated.
* avoid introducing Build/util.zig
* use doc comments for deprecation notices so that they show up in
generated documentation.
* introduce InstallArtifact.Options, accept it as a parameter to
addInstallArtifact, and move override_dest_dir into it. Instead of
configuring the installation via Compile step, configure the
installation via the InstallArtifact step. In retrospect this is
obvious.
* remove calls to pushInstalledFile in InstallArtifact. See #14943
* rewrite InstallArtifact to not incorrectly observe whether a Compile
step has any generated outputs. InstallArtifact is meant to trigger
output generation.
* fix child process evaluation code handling of `-fno-emit-bin`.
* don't store out_h_filename, out_ll_filename, etc., pointlessly. these
are all just simple extensions appended to the root name.
* make emit_directory optional. It's possible to have nothing outputted,
for example, if you're just type-checking.
* avoid passing -femit-foo/-fno-emit-foo when it is the default
* rename ConfigHeader.getTemplate to getOutput
* deprecate addOptionArtifact
* update the random number seed of Options step caching.
* avoid using `inline for` pointlessly
* avoid using `override_Dest_dir` pointlessly
* avoid emitting an executable pointlessly in test cases
Removes forceBuild and forceEmit. Let's consider these additions separately.
Nearly all of the usage sites were suspicious.
This reverts commit c75e11bf6aa67f2ca62b9b6677d134592777bfec.
Caused this problem on some machines:
"this step declares an upper bound of 9126805504 bytes of memory,
exceeding the available 7515721728 bytes of memory".
Instead the next commit will disable std lib tests with the C backend on
Windows.
I observed clang taking 8G to compile the output from the std lib tests
using the C backend. This commit should make the Windows CI stop failing
due to OOM.
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.
