Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
When we have a `ret_load` instruction with a zero-sized type which was
not an error, we would not emit any instruction. This resulted in
no `return` instruction and also not correctly resetting the global
stack_pointer.
This commit also enables the regular test runner for the WebAssembly
backend.
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.
This reverts commit 1a32f2a7f4.
Sorry, this workaround is not welcome. Instead, please solve the actual
issue by doing the accepted behavior in the compiler itself:
> in a catch or else (handling a returned error), if the block does not
> try or return error.xyz, set the index to 0
This also applies to if statements, such as the one that test runner is
doing just above this hack.
Essentially #1923 means "caught" errors still show up in error return traces.
The correct fix would require the compiler to fix this, but that could affect performance.
For now, simply workaround this issue by clearing the return traces
between tests.
This means that "caught" errors in one test will not show up in the
error traces of other tests.
stage2: change logic for detecting whether the main package is inside
the std package. Previously it relied on realpath() which is not portable.
This uses resolve() which is how imports already work.
* stage2: fix cleanup bug when creating Module
* flatten lib/std/special/* to lib/*
- this was motivated by making main_pkg_is_inside_std false for
compiler_rt & friends.
* rename "mini libc" to "universal libc"
