This seems to work around a very puzzling miscompilation first
present in LLVM 21.x. We already unconditionally add these
clobbers to inline assembly that came from the source, the
valgrind requests should also contain them.

Elf2: start implementing input object loading
|
|
|

`std.Io.tty.Config.detect` may be an expensive check (e.g. involving
syscalls), and doing it every time we need to print isn't really
necessary; under normal usage, we can compute the value once and cache
it for the whole program's execution. Since anyone outputting to stderr
may reasonably want this information (in fact they are very likely to),
it makes sense to cache it and return it from `lockStderrWriter`. Call
sites who do not need it will experience no significant overhead, and
can just ignore the TTY config with a `const w, _` destructure.

std: Introduce `Io` Interface
|
|
As with Solaris (dba1bf935390ddb0184a4dc72245454de6c06fd2), we have no way to
actually audit contributions for these OSs. IBM also makes it even harder than
Oracle to actually obtain these OSs.

The compiler crashed when we tried to call a function pointer for which
the type signature does not match any function body or function import
in the entire wasm executable, because there is no way to create a
reference to a function without it being in the function table or import
table. Solution is to make this instruction lower to unreachable.

only thing remaining is using libc dns resolution when linking libc

compiler toolchains have no business knowing what time it is

The logic for computing reference traces was unintentionally finding the
*longest* possible trace (approximately). I think I already tried to fix
this before, but misunderstood how my own code works. Here, we fix it
properly: by slightly reworking the logic to use one ArrayHashMap for
both the result and the traversal queue, we trivially get a proper
breadth-first traversal so that we can find the shortest possible
reference trace for every referenced unit.

feat: init x86_16 arch via CBE
|

There is no straightforward way for the Zig team to access the Solaris system
headers; to do this, one has to create an Oracle account, accept their EULA to
download the installer ISO, and finally install it on a machine or VM. We do not
have to jump through hoops like this for any other OS that we support, and no
one on the team has expressed willingness to do it.
As a result, we cannot audit any Solaris contributions to std.c or other
similarly sensitive parts of the standard library. The best we would be able to
do is assume that Solaris and illumos are 100% compatible with no way to verify
that assumption. But at that point, the solaris and illumos OS tags would be
functionally identical anyway.
For Solaris especially, any contributions that involve APIs introduced after the
OS was made closed-source would also be inherently more risky than equivalent
contributions for other proprietary OSs due to the case of Google LLC v. Oracle
America, Inc., wherein Oracle clearly demonstrated its willingness to pursue
legal action against entities that merely copy API declarations.
Finally, Oracle laid off most of the Solaris team in 2017; the OS has been in
maintenance mode since, presumably to be retired completely sometime in the 2030s.
For these reasons, this commit removes all Oracle Solaris support.
Anyone who still wishes to use Zig on Solaris can try their luck by simply using
illumos instead of solaris in target triples - chances are it'll work. But there
will be no effort from the Zig team to support this use case; we recommend that
people move to illumos instead.

This was forgotten during the refactoring of std.builtin.CallingConvention. It

The value being computed here is almost always equal to the pointer bit width.

Renames arePointersLogical to shouldBlockPointerOps for clarity
adds capability check to allow pointer ops on .storage_buffer when
variable_pointers capability is enabled.
