Closes #23949.

no active maintainer, and it's failing to lower some basic stuff

Soft float is a very rare use case for riscv*-linux. No point wasting CI
resources on these targets, especially since our arm and mips soft float
coverage is already likely to catch most soft float bugs.
|
|
Without this change, by default you get a failure when trying to cross
compile for these targets.
freebsd was error: undefined symbol: __libc_start1
netbsd was warning: invalid target NetBSD libc version: 9.4.0
error: unable to build NetBSD libc shared objects: InvalidTargetLibCVersion
now they work by default

added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly

Closes #23971.

It's kind of unclear what `*-windows-none` actually means, but as far as LLVM is
concerned, it's equivalent to `*-windows-msvc`. For clarity, only test
`*-windows-msvc` and `*-windows-gnu`. #20690 will clean this situation up
eventually.
Also ensure coverage of `link_libc = true` and `link_libc = false` for both.

Now that codegen has no references to linker state this is much easier.
Closes #24153

This struct is larger than 256 bytes and code that copies it
consistently shows up in profiles of the compiler.
|
|
e.g. `x86_64-windows.win10...win11_dt-gnu` -> `x86_64-windows-gnu`
When the OS version is the default this is redundant with checking the
default in the standard library.

std tests are temporarily disabled for arm-freebsd-eabihf due to #23949.
I omitted x86-freebsd-none and powerpc-freebsd-none because these will be
dropped in FreeBSD 15.0 anyway, so there's no point in us spending resources on
those now.
|
|
There's not really any point in targeting *-windows-(gnu,msvc) when not linking
libc, so add entries for *-windows-(gnu,msvc) that actually link libc, and
change the old non-libc entries to *-windows-none.
Also add missing aarch64-windows-(none,msvc) and thumb-windows-(none,msvc)
entries. thumb-windows-gnu is disabled for now due to #24016.
|
|
We can't provide MSVC libc when cross-compiling (yet?).
|
|
I removed the commented-out entries for backends that are bitrotted. Can add
these back later when we reboot those backends.

spirv: unroll all vector operations

Since we need testing for passing `--build-file` and `--cache-dir`
together anyway, use it to test the disabled build options test.

Building upstream musl for this target works now that we use hidden visibility
for compiler-rt symbols.
|
|
This reflects how the compiler actually treats it.
Closes #23424.

Most of these are gated by -Dtest-extra-targets because:
* We don't really have CI resources to spare at the moment.
* They're relatively niche if you're not on a musl distro.
* And the few musl distros that exist don't support all these targets.
* Quite a few of them are broken and need investigating.
x86_64-linux-musl and aarch64-linux-musl are not gated as they're the most
common targets that people will be running dynamic musl on, so we'll want to
have some bare minimum coverage of those.

Introduce libzigc for libc function implementations in Zig
|
|
This lays the groundwork for #2879. This library will be built and linked when a
static libc is going to be linked into the compilation. Currently, that means
musl, wasi-libc, and MinGW-w64. As a demonstration, this commit removes the musl
C code for a few string functions and implements them in libzigc. This means
that those libzigc functions are now load-bearing for musl and wasi-libc.
Note that if a function has an implementation in compiler-rt already, libzigc
should not implement it. Instead, as we recently did for memcpy/memmove, we
should delete the libc copy and rely on the compiler-rt implementation.
I repurposed the existing "universal libc" code to do this. That code hadn't
seen development beyond basic string functions in years, and was only usable-ish
on freestanding. I think that if we want to seriously pursue the idea of Zig
providing a freestanding libc, we should do so only after defining clear goals
(and non-goals) for it. See also #22240 for a similar case.

Step.Compile: use LtoMode enum for lto option
|
|
Currently skips std tests which have many issues.
|
|
This can be used more broadly for targets that aren't quite ready to be tested
by default yet.
|
|
We can now run these tests as part of test-modules w/o -Dtest-slow-targets.
Closes #21096.

I think the underlying issue was the same as
https://github.com/ziglang/zig/issues/13258 and that has a work-around in
LLVM 19 (see https://github.com/llvm/llvm-project/issues/58557).
Fixes #15325

This reverts commit dea72d15da4fba909dc3ccb2e9dc5286372ac023, reversing
changes made to ab381933c87bcc744058d25a876cfdc0d23fc674.
The changeset does not work as advertised and does not have sufficient
test coverage.
Reopens #22822

module in the build graph instead of storing a
