Marcin Ślusarz 23f8f836e0 nir/print: group hex and float vectors together
Vectors are much easier to follow in this format, because developer cares
either about hex or float values, never both.

Some of the tested flags are set for other intrinsics and they are

Caio Oliveira b1156f23a2 Revert "nir: disable a NIR test due to undebuggable & locally unreproducible CI failures"
This reverts commit 6eb3fe2d4f.  The root cause was
a bug in Meson when using the new gtest protocol and a test failed before producing
the XML file expected by it.  This was fixed in later versions of Meson, so
we've bumped the required meson version to use that feature.  The failure should
now be properly identified, so re-enabling the NIR test.

Marek Olšák 6eb3fe2d4f nir: disable a NIR test due to undebuggable & locally unreproducible CI failures
debian-vulkan but not any other CI pipeline consistently fails with:
    FileNotFoundError: [Errno 2] No such file or directory: 'nir_tests.xml'

I have to assume that either debian-vulkan is broken, or the NIR test
infrastructure is broken. That's not all. I got the same failure when
I wanted to add a new test, which means the CI is preventing us from adding
new NIR tests, which is a very serious problem with the CI or NIR tests.
The python error doesn't imply that it's a test failure, so something else
is broken. If you don't want such commits to happen again, print better
error messages.

Rhys Perry 5c0fe11072 nir/opt_offsets: fix try_extract_const_addition recursion
This initially looks like a miscompilation bug, but I don't think it's
actually possible for it to create incorrect code.

Juan A. Suarez Romero f77ccdfb4a nir: add NIR_DEBUG envvar
Move all the NIR related debug environmental variables in a single
NIR_DEBUG one.

Use NIR_DEBUG=help to print all the available options.

v2:
 - Use a macro to simplify (Marcin, Jason)
 - Remove wrong changes (Marcin)

v3 (Marcin):
 - Remove rendundant NIR mentioning in option descriptions.
 - Unwrap option descriptions.
 - Ensure the constant is unsigned.
 - Use extern array to remove switch.

v4:
 - Add missing kernel shader (Jason).
 - Add unlikely() (Marcin).

Emma Anholt 06fe04b4d7 nir: Make nir_build_alu() variants per 1-4 arg count.
This saves a bunch of generated code to pack up the extra NULLs to get to
4 args, and saves executing the conditions in nir_build_alu() to then skip
those NULLs.

Saves another 27kb on disk.

Emma Anholt e770ec1182 nir: Uninline a bunch of nir.h functions.
I aimed for "things that look like big switch statements, or cases where
the compiler is unlikely to be able to constant-propagate an argument into
something useful."

Saves another 80kb on disk.  No perf difference on iris shader-db, n=23.

Viktoriia Palianytsia 6f54ebe44f glsl: fix for unused variable in glsl_types.cpp
Unused variable vector_elements is now used in return from
function decode_type_from_blob instead of encoded.basic.vector_elements.
In the code we can see how those variables were equated
and then the operations were made exactly to vector_elements.
But variable didn't pass into any other variables or functions.
