The motivating case for this is that currently when a test fails
the CI log will include ~5k lines of listing steps that succeeded.

Split `std.mem.split` and `tokenize` into `sequence`, `any`, and `scalar` versions

`-l :path/to/lib.so` behavior on gcc/clang is:
- the path is recorded as-is: no paths, exact filename (`libX.so.Y`).
- no rpaths.
The previous version removed the `:` and pretended it's a positional
argument to the linker. That works in almost all cases, except in how
rules_go[1] does things (the Bazel wrapper for Go).
Test case in #15743, output:
gcc rpath:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/x]
gcc plain:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
zig cc rpath:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/x]
zig cc plain:
0x0000000000000001 (NEEDED) Shared library: [libversioned.so.2]
Fixes #15743

Also get rid of the TTY wrapper struct, which was exlusively used as a
namespace - this is done by the tty.zig root struct now.
detectTTYConfig has been renamed to just detectConfig, which is enough
given the new namespace. Additionally, a doc comment had been added.

No functional changes. This renames an internal build option to better
reflect how it is used.

When producing zig2.c, don't waste time emitting C code for subcommands
that won't be used, such as objcopy.
This takes zig2.c down from 111M to 109M, and sidesteps some unfortunate
warnings that are currently emitted by GCC.

stage2: implement `--build-id` styles

closes #7170

* build.zig: the result of b.option() can be assigned directly in many
cases thanks to the return type being an optional
* std.Build: make the build system aware of the
std.Build.Step.Compile.BuildId type when used as an option.
- remove extraneous newlines in error logs
* simplify caching logic
* simplify hexstring parsing tests and use a doc test
* simplify hashing logic. don't use an optional when the `none` tag
already provides this meaning.
* CLI: fix incorrect linker arg parsing

In one of the happy paths, execve() is used to switch to clang in which
case any cleanup logic that exists for this temporary file will not run
and this temp file will be leaked. Oh well. It's a minor punishment for
using `-x c` which nobody should be doing. Therefore, we make no effort
to clean up. Using `-` for stdin as a source file always leaks a temp
file.
Note that the standard `zig build-exe` CLI does not support stdin as an
input file. This is only for `zig cc` C compiler compatibility.

* no need to move `tmpFilePath` around
* no need for calculating max length of `FileExt` tag name
* provide a canonical file extension name for `FileExt` so that, e.g.
the file will be named `stdin.S` instead of
`stdin.assembly_with_cpp`.
* move temp file cleanup to a function to reduce defer bloat in a large
function.
* fix bug caused by mixing relative and absolute paths in the cleanup
logic.
* remove commented out test and dead code

echo 'some C program' | $CC -x c -
Is a common pattern to test for compiler or linker features. This patch
adds support for reading from non-regular files.
This will make at least one more Go test to pass.

Everywhere that can now use `splitScalar` should get a nice little performance boost.

* docs(std.math): elaborate on difference between absCast and absInt
* docs(std.rand.Random.weightedIndex): elaborate on likelihood
I think this makes it easier to understand.
* langref: add small reminder
* docs(std.fs.path.extension): brevity
* docs(std.bit_set.StaticBitSet): mention the specific types
* std.debug.TTY: explain what purpose this struct serves
This should also make it clearer that this struct is not supposed to provide unrelated terminal manipulation functionality such as setting the cursor position or something because terminals are complicated and we should keep this struct simple and focused on debugging.
* langref(package listing): brevity
* langref: explain what exactly `threadlocal` causes to happen
* std.array_list: link between swapRemove and orderedRemove
Maybe this can serve as a TLDR and make it easier to decide.
* PrefetchOptions.locality: clarify docs that this is a range
This confused me previously and I thought I can only use either 0 or 3.
* fix typos and more
* std.builtin.CallingConvention: document some CCs
* langref: explain possibly cryptic names
I think it helps knowing what exactly these acronyms (@clz and @ctz) and
abbreviations (@popCount) mean.
* variadic function error: add missing preposition
* std.fmt.format docs: nicely hyphenate
* help menu: say what to optimize for
I think this is slightly more specific than just calling it
"optimizations". These are speed optimizations. I used the word
"performance" here.
|
|
* CompileStep: Avoid calling producesPdbFile() to determine whether the
option should be respected. If the user asks for it, put it on the
command line and let the Zig CLI deal with it appropriately.
* Make the namespace of `std.dwarf.Format.dwarf32` no longer have a
redundant "dwarf" in it.
* Add `zig cc` integration for `-gdwarf32` and `-gdwarf64`.
* Toss in a bonus bug fix for `-gdwarf-2`, `-gdwarf-3`, etc.
* Avoid using default init values for struct fields unnecessarily.
* Add missing cache hash addition for the new option.

This commit enables producing 64-bit DWARF format for Zig executables
that are produced through the LLVM backend. This is achieved by exposing
both command-line flags and CompileStep flags. The production of the
64-bit format only affects binaries that use the DWARF format and it is
disabled on MacOS due to it being problematic. This commit, despite
generating the interface for the Zig user to be able to tell the compile
which format is wanted, is just implemented for the LLVM backend, so
clang and the self-hosted backends will need this to be implemented in a
future commit.
This is an effort to work around #7962, since the emission of the 64-bit
format automatically produces 64-bit relocations. Further investigation
will be needed to make DWARF 32-bit format to emit bigger relocations
when needed and not make the linker angry.

main: consume --debug-log argument even when logging is disabled

Closes #15258
|
|
This use case is now handled instead by the --listen option.
closes #15025
closes #15072

This makes -r treated the same as -c which is to output an object file.
Zig's ELF linker code already handles multiple object files into an
object file with the -r flag to LLD.
closes #11683
|
|
* use a set instead of a list
* use of this flag currently requires LLD
* add documentation
* make it only a zig cc compatibility flag for now because I personally
think this is an anti-feature.

Also clean up parsing of linker args - reuse `ArgsIterator`.
In MachO, ensure we add every symbol marked with `-u` as undefined
before proceeding with symbol resolution. Additionally, ensure those
symbols are never garbage collected.
MachO entry_in_dylib test: pass `-u _my_main` when linking executable
so that it is not incorrectly garbage collected by the linker.
|

Ideally, we would just do an atomic rename, but so far I had no
luck. I have also tried marking the file to delete-on-close but
then we cannot use it to spawn the process. So for now, let's just
put a copy in `zig-cache` and let the user decide when to recycle
the cache dir.

pass the negation to lld, and add --no-dynamicbase
build: expose linker_dynamicbase on CompileStep and map it to emit --no-dynamicbase

The compiler REPL will move to an external process that communicates
with the compiler over the binary protocol.

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 commit extracts out server code into src/Server.zig and uses it
both in the main CLI as well as `zig objcopy`.
std.Build.ObjCopyStep now adds `--listen=-` to the CLI for `zig objcopy`
and observes the protocol for progress and other kinds of integrations.
This fixes the last two test failures of this branch when I run
`zig build test` locally.
|
|
* std.zig.ErrorBundle: support rendering options for whether to include
the reference trace, whether to include the source line, and TTY
configuration.
* build runner: don't print progress in dumb terminals
* std.Build.CompileStep:
- add a way to expect compilation errors via the new `expect_errors`
field. This is an advanced setting that can change the intent of
the CompileStep. If this slice has nonzero length, it means that
the CompileStep exists to check for compile errors and return
*success* if they match, and failure otherwise.
- remove the object format parameter from `checkObject`. The object
format is known based on the CompileStep's target.
- Avoid passing -L and -I flags for nonexistent directories within
search_prefixes. This prevents a warning, that should probably be
upgraded to an error in Zig's CLI parsing code, when the linker
sees an -L directory that does not exist.
* std.Build.Step:
- When spawning the zig compiler process, takes advantage of the new
`std.Progress.Node.setName` API to avoid ticking up a meaningless
number at every progress update.
