This enables the PIPE_CAP_OCCLUSION_QUERY capability without adding an

This is necessary to get Mesa to report desktop GL 2.0 support (to run
exciting things such as ioq3's OpenGL 2 renderer), and should be valid
because exposing the capability does not guarantee that any

configure.ac: Respect LLVM_CFLAGS in LLVM version detection
When compiling LLVM headers, including llvm-config.h, we need to respect
LLVM_CFLAGS. This is especially crucial if LLVM is located in a
non-standard location and it happens that llvm-config.h includes another
header. In such case the detection would fail due to missing header,
because the path is provided in LLVM_CFLAGS.
Let's add LLVM_CFLAGS to global CFLAGS for the time of detection and then
restore the original flags, as done in other places of the script.

glsl: Make copy propagation not panic when it sees an intrinsic.
A number of games have large arrays of constants, which we promote to
uniforms. This introduces copies from the uniform array to the original
temporary array. Normally, copy propagation eliminates those copies,
making everything refer to the uniform array directly.
A number of shaders in "Deus Ex: Mankind Divided" recently exposed a
limitation of copy propagation - if we had any intrinsics (i.e. image
access in a compute shader), we weren't able to get rid of these copies.
That meant that any variable indexing remained on the temporary array
rather being moved to the uniform array. i965's scalar backend
currently doesn't support indirect addressing of temporary arrays,
which meant lowering it to if-ladders. This was horrible.
According to Marek, on radeonsi/GCN, "F1 2015" uses 64% less
spilled-temp-array memory.
On i965/Skylake:
total instructions in shared programs: 13362954 -> 13329878 (-0.25%)
instructions in affected programs: 43745 -> 10669 (-75.61%)

Helps Deus Ex: Mankind Divided. The one shader with hurt spills/fills
is from Tomb Raider at Ultra settings, but that same shader has a
-39.55% reduction in instructions and -14.09% reduction in cycle counts,
so it seems like a win there as well.

i965: Make DCE set null destinations on messages with side effects.
(Co-authored by Matt Turner.)
Image atomics, for example, return a value - but the shader may not
want to use it. We assigned a useless VGRF destination. This seemed
harmless, but it can actually be quite harmful. The register allocator
has to assign that VGRF to a real register. It may assign the same
actual GRF to the destination of an instruction that follows soon after.
This results in a write-after-write (WAW) dependency, and stall.
A number of "Deus Ex: Mankind Divided" shaders use image atomics, but
don't use the return value. Several of these were hitting WAW stalls
for nearly 14,000 (poorly estimated) cycles a pop. Making dead code
elimination null out the destination avoids this issue.
This patch cuts one shader's estimated cycles by -98.39%! Removing the
message response should also help with data cluster bandwidth.
On Skylake:

total cycles in shared programs: 255413890 -> 248081010 (-2.87%)

i965: Combine some dead code elimination NOP'ing code.
In theory we might have incorrectly NOP'd instructions that write the
flag, but where that flag value isn't used, and yet the instruction
either writes the accumulator or has side effects.
I don't believe any such instructions exist, so this is mostly a
code cleanup.
Curro pointed out that FS_OPCODE_FB_WRITE has a null destination and
actually writes the flag on Gen4-5 to dynamically decide whether to
write some payload data. The hunk removed in this patch might have
NOP'd it, except that we don't actually mark flags_written() in the
IR, so it doesn't think the flag is touched at all. That's sketchy,
but it means it wouldn't hit this today (though there are likely other
problems!).
v2: Properly replace the inst->regs_written() check in the second
hunk with the flag being live (mistake caught by Curro).

i965: Make DCE explicitly not eliminate any control flow instructions.
According to Matt, the dead code pass explicitly avoided IF and WHILE
because on Sandybridge, these could have conditional modifiers and
null destination registers. Normally, those instructions use BAD_FILE
for the destination register. Nowadays, we don't do that anymore, so
we could technically drop these checks.
However, it's clearer to explicitly leave control flow instructions
alone, so change it to the more generic !inst->is_control_flow().
This should have no actual change.

The same we do in the OpenGL driver (comment copied from there).
This is required to ensure that we execute the fragment shader stage when

I found this while writing a test to check rendering to a framebuffer
without attachments where the fragment shader does not produce any
color outputs but writes to an image via imageStore(). Without this patch
the fragment shader does not execute and the image is not written,
which is not correct.
