os_get_option() is a wrapper for getenv() that checks properties in
Android. It should be a no-op for other OS but will allow full use of
env vars in Android.
The environment variable names are automatically renamed by
os_get_option() and the order of precedence thus becomes:
1. getenv (non-Android)
2. debug.mesa.* (Android)
3. vendor.mesa.* (Android)
4. mesa.* (Android, as a fallback for older versions)

Most of the time with nir_def_rewrite_uses_after, you want to rewrite after the

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

NIR is going to use exec_node/list without the C++ code, and may switch to
a different linked list implementation in the future.
GLSL is going to use ir_exec_node/list, which we want to keep private
for GLSL, so that we can change it easily.
Thus, it's better to fork the C++ version of list.h for Intel.

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 && \

Similar to nir_lower_alu_width(), the callback can return the
desired number of components for a phi, or 0 for no lowering.
The previous behavior of nir_lower_phis_to_scalar() with lower_all=true
can be elicited via nir_lower_all_phis_to_scalar() while the previous
behavior with lower_all=false now corresponds to nir_lower_phis_to_scalar()
with NULL callback.

`subprocess.Popen()` returns immediately, and the subprocess might not
have finished by the time `stdout` is read on the next line, spuriously
failing the tests.
`subprocess.check_output()` makes sure the output is available before
returning, solving this issue; it additionally raises an error if the
subprocess failed, giving a better error than a failed diff later in the

This moves some conversions to NIR that may get eliminated, and also
distinguishes gl_FragCoord.z/w loads at the shader info level so we don't
need to flag uses_src_depth/uses_src_w when only gl_FragCoord.xy get used
(as is typical). This reduces thread payload setup on many shaders.
Also, interestingly, blorp shaders stop reserving space for z/w despite
not putting them in the payload (since PS_EXTRA isn't filled out for z/w).

This generates one extra instruction to set the rounding mode to RTE due
to f2f16_rtne in the lowering. This changes the result for
fquantize2f16(65505.0) from 65536 to 65504, which fixes SPIR-V
conformance for this value:
If Value is positive with a magnitude too large to represent as a
16-bit floating-point value, the result is positive infinity. If Value
is negative with a magnitude too large to represent as a 16-bit
floating-point value, the result is negative infinity.
SPIR-V doesn't specify whether this overflow check is before or after
rounding, but IEEE specifies rounding first, which is what produces our
65504.
