* r600: fix abs for op3 sourcesRoland Scheidegger2018-03-141-54/+56
| | | | | | | | | | | | | | | | | | | If a src was referencing the same temp as the dst, the per-component copy code didn't work. e.g. cndge r0.xy, r0.xx, |r2|, r3 got expanded into mov r12.x, |r2| cndge r0.x, r0.x, r12, r3 mov r12.y, |r2| cndge r0.y, r0.x, r12, r3 hence for the second cndge r0.x was mistakenly the previous cndge result. Fix this by doing all the movs first, so there's no bogus alu.last in between.

* r600: implement callstack workaround for evergreen.Dave Airlie2018-03-121-8/+31
| | | | | | | | | | | | | | | | | | | | This is ported from the sb backend, there are some issues with evergreen stacks on the boundary between entries and ALU_PUSH_BEFORE instructions. Whenever we are going to use a push before, we check the stack usage and if we have to use the workaround, then we switch to a separate push. I noticed this problem dealing with some of the soft fp64 shaders, in nosb mode, they are quite stack happy.

Two cases are handled with this patch: 1. If copy propagation tries to eliminated a move from a relative array access then it could optimize MOV R1, ARRAY[RELADDR_1] MOV R2, ARRAY[RELADDR_2] OP2 R3, R1 R2 into OP2 R3, ARRAY[RELADDR_1], ARRAY[RELADDR_2] which is forbidden, because there is only one address register available. 2. When MULADD(x,a,MUL(x,c)) is handled MUL TMP, R1, ARRAY[RELADDR_1] MULLADD R3, R1, ARRAY[RELADDR_2], TMP by folding this into ADD TMP, ARRAY[RELADDR_2], ARRAY[RELADDR_1] MUL R3, R1, TMP which is also forbidden. Test for these cases and reject the optimization if a forbidden combination of relative access would be created.

* r600: partly fix sampleMaskIn valueRoland Scheidegger2018-02-081-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | The hw gives us coverage for pixel, not for individual fragment shader invocations, in case execution isn't per pixel (eg, unlike cm, actually cannot do "real" minSampleShading, it's either per-pixel or per-fragment, but it doesn't really make a difference here). Also, with msaa disabled, the hw still gives us a mask corresponding to the number of samples, where GL requires this to be 1. Fix this up by masking the sampleMaskIn bits with the bit corresponding to the sampleID, if we know this shader is always executed at per-sample granularity. (In case of a per-sample frequency shader and msaa disabled, the sampleID will always be 0, so this works just fine there.) Fixing this for the minSampleShading case will need a shader key (radeonsi uses the prolog part for) (for eg, could get away with a single bit, cm would need more bits depending on sample/invocation ratio, or read the bits from a uniform), unless we'd want to always use a sample mask uniform (which is probably not a good idea, as it would make the ordinary common msaa case slower for no good reason). This fixes some parts of piglit arb_sample_shading-samplemask (with fixed test), in particular those which use a sampleID, still failing others as expected.

* r600: clean up fragment shader input scan codeRoland Scheidegger2018-02-081-52/+23
| | | | | | | | | | | | | For some reason, we were iterating through the code twice (first just for instructions needing barycentrics, then for instructions and input dcls). Move things around slightly so this is no longer necessary. There also was a unnedeed enabling of the fixed_pt_position_gpr - this is only needed if the per-sample interpolation comes from an input, not from an instruction (just move the assert where it belongs) (since the sample id to sample from comes from a tgsi src in this case, and isn't sampleID). Otherwise there should be no functional change. Reviewed-by: Dave Airlie <[email protected]>
