Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run
Take the write_mask into account when storing primitive indices,
otherwise they will end up being stored in the wrong place.

We already lower all 64-bit I/O to 32-bit before this pass,
and the rest of the code here already asserts that I/O variables
must be 32-bit or smaller.

b2ea120732 ac,radv,radeonsi: fix programming PA_SU_PRIM_FILTER_CNTL on GFX12
GFX12 seems to behave slightly differently. Setting these bits to TRUE
causes zero-area triangles to not pass the primitive clipping stage.
So, the actual number of primitives output by the primitive clipping
stage was wrong.

After digging a lot, it seems PAL doesn't set these bits either on
GFX12.

82ae8b1d33 treewide: simplify nir_def_rewrite_uses_after
Most of the time with nir_def_rewrite_uses_after, you want to rewrite after the
replacement. Make that the default thing to be more ergonomic and to drop
parent_instr uses.

We leave nir_def_rewrite_uses_after_instr defined if you really want the old
signature with an arbitrary after point.

Via Coccinelle patch:

    @@
    expression a, b;
    @@

    -nir_def_rewrite_uses_after(a, b, b->parent_instr)
    +nir_def_rewrite_uses_after_def(a, b)

Followed by a bunch of sed.

ddf2aa3a4d build: avoid redefining unreachable() which is standard in C23
In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>

See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in

And this causes build errors when building for C23:

-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
                 from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
  123 | #define unreachable(str)    \
      |         ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
  456 | #define unreachable() (__builtin_unreachable ())
      |         ^~~~~~~~~~~
-----------------------------------------------------------------------

So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.

Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.

This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.

All the instances of the macro, including the definition, were updated
with the following command line:

  git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
  while read file; \
  do \
    sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
  done && \
  sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

43f18f5615 ac/nir: mark all input loads as reorderable and speculatable (for LICM)
These are only memory loads.

We could do the same for LDS loads, which are not truly speculatable
in merged shaders (can't be moved before the barrier), but that's fine
because LICM only moves code out of loops, which can't have barriers.
