| | | | | | | | | | | | | | | | | | | The implementation was added with commit d085a5dff5b and effectively provided a hidden dependency. Namely: the codepath used was determined solely during build time. Thus if we built again new wayland and then run against older (yet still within the requirements, as per the configure) one will get undefined symbols. As of earlier commit 36b9976e1f9 "egl/wayland: Avoid race conditions when on non-main thread" the required version was bumped to one which provides the API, thus we can drop the quirky solution.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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.

| | | | | | | | | | | | | | | | | | | | | | | | 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).
