This has been merged few months ago but this should help
https://mesamatrix.net/ to update its list of supported extensions.
Please note that compute shaders are not really useful without
ARB_image_load_store and only GK104 and GK110 support it for now.

3D images are a bit more complicated to implement and will probably
requires a bunch of headaches and we don't care for now because they
do not seem to be really used by apps.

This re-uses NVE4_SU_INFO_CALL which is not used anymore because we
don't use our lib for format conversions. While we are at it, add a
todo for image buffers because there are some robustness-related
issues to fix.

Checking if the image address is not 0 should be enough to prevent
read faults. To improve robustness, make sure that the destination
value of atomic operations is correctly initialized in case the
instruction is not performed.

This implements RESQ for surfaces which comes from imageSize() GLSL
bultin. As the dimensions are sticked into the driver constant buffer,
this only has to be lowered with loads.

TGSI RESQ allows both images and buffers but we have to make a
distinction between these two type of resources in our lowering pass.
Introducing OP_BUFQ which is a fake operand will allow to implement
OP_SUQ for surfaces.

This feature can be enabled in two ways: as an optimization and by
explicit user control (with OpenGL 4.2 or ARB_shader_image_load_store).
This makes use of the recent TGSI_PROPERTY_FS_EARLY_DEPTH_STENCIL to
force early fragment tests when needed.
This fixes a bunch of
dEQP-GLES31.functional.image_load_store.early_fragment_tests.* tests.

Old surfaces validation code will be removed once images are completely

To process surfaces coordinates from the codegen part, and because
some information like the format is not always available (eg. when
writeonly is used), we have to stick some surfaces data in the
driver constbuf. This is especially true for OpenCL because we don't
know the format at shader compile time.
This bumps the size of each shader area from 1K to 2K.

This implements set_shader_images() and resource invalidation for
images. As OpenGL requires at least 8 images, we are going to expose
this minimum value even if this might be raised for Kepler, but this
limit is mainly for Fermi because the hardware only accepts 8 images.

The third source must be emitted at offset 49 instead of 17 and the
not modifier is at 52 instead of 20. If you look a bit above in
emitLogicOp() you will see that the dest is emitted at 17 which
confirms that src(2) is obviously wrong.

- Introduce 'gcc_compat' env flag, for all compilers that define __GNUC__,
(which includes Clang when it's not emulating MSVC.)
- Clang doesn't support whole program optimization
- Disable enumerator value warnings (not sure why Clang warns about them,
as my understanding is that MSVC promotes enums to unsigned ints
automatically.)
This is not enough to build with Clang + AddressSanitizer though. More
follow up changes will be required for that.

These were being defined in SCons, but it's not practical:
- we actually need to include Gallium headers from external source trees, with
completely disjoint build infrastructure, and it's unsustainable to
replicate the HAVE_xxx checks or even hard-coded defines across
everywhere.
- checking compiler version via command line doesn't really work due to
Clang essentially being like a cameleon which can fake either GCC or
MSVC
There's no change for autoconf.
