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.
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.
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.
This reverts commit dea72d15da, reversing
changes made to ab381933c8.
The changeset does not work as advertised and does not have sufficient
test coverage.
Reopens#22822
The relocation range issues will happen eventually as we add more code to the
standard library and test suites, so we may as well just deal with this now.
@MasonRemaley ran into this in #20271, for example.
There are several test decls inside `/src` that are not currently being
tested and have bitrotted as a result. This commit revives those tests
and adds the `test-compiler-internals` set of tests which tests
everything reachable from `/src/main.zig`.
