* etnaviv: Fake occlusion query capabilityWladimir J. van der Laan2017-01-181-2/+3
| | | | | | | | | | | | | This enables the PIPE_CAP_OCCLUSION_QUERY capability without adding an occlusion query type. 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 counters are actually implemented.

* configure.ac: Respect LLVM_CFLAGS in LLVM version detectionTomasz Figa2017-01-181-0/+6
| | | | | | | | | | | | | | 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.Kenneth Graunke2017-01-171-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%) helped: 12 HURT: 0 total cycles in shared programs: 248081010 -> 245949178 (-0.86%) cycles in affected programs: 4597930 -> 2466098 (-46.37%) helped: 12 HURT: 0 total spills in shared programs: 9493 -> 9507 (0.15%) spills in affected programs: 25 -> 39 (56.00%) helped: 0 HURT: 1 total fills in shared programs: 12127 -> 12197 (0.58%) fills in affected programs: 110 -> 180 (63.64%) helped: 0 HURT: 1 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.Kenneth Graunke2017-01-171-13/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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: (instruction counts remain identical) total cycles in shared programs: 255413890 -> 248081010 (-2.87%) cycles in affected programs: 12019948 -> 4687068 (-61.01%) helped: 24 HURT: 10 v2: Make can_omit_write independent of can_eliminate (Curro).

* i965: Combine some dead code elimination NOP'ing code.Kenneth Graunke2017-01-171-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.Kenneth Graunke2017-01-171-3/+2
| | | | | | | | | | | | | | | | | | | 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.
