* gallivm: optimize lp_build_unpack_arith_rgba_aos slightlyRoland Scheidegger2017-01-051-19/+97
| | | | | | | | | | | | | | | | | This code uses a vector shift which has to be emulated on x86 unless there's AVX2. Luckily in some cases we can actually avoid the shift altogether, so do that. Also make sure we hit the fast lp_build_conv() path when applicable, albeit that's quite the hack... That said, this path is taken for AoS sampling for small unorm (smaller than rgba8) formats, and it is completely hopeless even with those changes, with or without AVX. (Probably should have some code similar to the one in the llvmpipe fs backend code, using bit replication to extend to rgba8888 - rounding is not quite 100% accurate but if it's good enough there it should be here as well.)

* gallivm: use 2 srcs for 32->16bit conversions in lp_bld_conv_autoRoland Scheidegger2017-01-051-2/+19
| | | | | | | | | | | | | | | | | If we only feed one source vector at a time, we cannot use pack intrinsics (as we only have a 64bit destination dst vector). lp_bld_conv_auto is specifically designed to alter the length and number of destination vectors, so this works just fine (if we use single source vectors at a time, afterwards we immediately reassemble the vectors). For AVX though this isn't really possible, since we expect 128bit output already for a single 256bit input. (One day we should handle AVX2 which again would need multiple inputs, however there's the problem that we get different ordered output there and we don't want to reorder, so would need to be able to tell build_conv to handle upper and lower halfs independently.) A similar strategy would probably work for 32->8bit too (if it doesn't hit the special case) but I'm going to try something different for that... Reviewed-by: Jose Fonseca <[email protected]>
* llvmpipe: (trivial) minimally simplify mask constructionRoland Scheidegger2017-01-053-17/+53
| | | | | | | | | | | | | | | | simd instruction sets usually have comparisons for equal, not unequal. So use a different comparison against the mask itself - which also means we don't need a all-zero as well as a all-one (for the pxor) reg. Also add code to avoid scalar expansion of i1 values which we definitely shouldn't do. There's problems with this though with llvm select interaction, so it's disabled (basically using llvm select instead of intrinsics may still produce atrocious code, even in cases where we figured it should not, albeit I think this could probably be fixed with some better selection of optimization passes, but I have zero idea there really).

* anv: fix multiple creation with internal failureLionel Landwerlin2017-01-051-18/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The specification section 9.4 says : When an application attempts to create many pipelines in a single command, it is possible that some subset may fail creation. In that case, the corresponding entries in the pPipelines output array will be filled with VK_NULL_HANDLE values. If any pipeline fails creation (for example, due to out of memory errors), the vkCreate*Pipelines commands will return an error code. The implementation will attempt to create all pipelines, and only return VK_NULL_HANDLE values for those that actually failed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLSL compilation now takes 24% less time with the Gallium noop driver. I used my shader-db for the measurement. The difference for the whole radeonsi driver can be ~10%. The generated TGSI is mostly the same.

Note that glsl_to_tgsi does its own copy propagation and simple register allocation. shader-db GCN report: - Talos spills fewer SGPRs. - DOTA 2 spills more SGPRs. - The average shader-db score is better, but it's just due to randomness. 29045 shaders in 17564 tests Totals: SGPRS: 1325929 -> 1325017 (-0.07 %) VGPRS: 1010808 -> 1010172 (-0.06 %) Spilled SGPRs: 1432 -> 1399 (-2.30 %) Spilled VGPRs: 93 -> 92 (-1.08 %) Private memory VGPRs: 688 -> 688 (0.00 %) Scratch size: 2540 -> 2484 (-2.20 %) dwords per thread Code Size: 39336732 -> 39342936 (0.02 %) bytes Max Waves: 217937 -> 217969 (0.01 %) Reviewed-by: Eric Anholt <[email protected]>

Then, we'd construct another SEND with EOT, but with no actual payload data. That's not legal. For example, SSO programs have clip distance slots allocated no matter what, but the shader may not write them. If it doesn't write any user defined varyings, then the clip distance slots will be the last ones.

| | | | | | | | | | | | | | | | | | | | | | | | | | | GCC's preprocessor accepts a macro definition where there is no space between the macro's identifier name and the replacementlist. (GCC does emit a "missing space" warning that we don't, but that's fine.) This is an exhaustive test that verifies that all legal GLSL characters that could possibly be interpreted as separating the macro name from the replacement list are interpreted as such. So the testing here includes all valid GLSL symbols except for: * Characters that can be part of an identifier (a-z, A-Z, 0-9, _) * Backslash, (allowed only as line continuation) * Hash, (allowed only to introduce pre-processor directive, or as part of a paste operator in a replacement list---but not as first token of replacement list) * Space characters (since the point of the testing is to have missing space) * Left parenthesis (which would indicate a function-like macro) v2 (Ken): Move to src/compiler, renumber tests.
