* gallivm: add PK2H/UP2H supportRoland Scheidegger2016-02-025-2/+119
| | | | | | | | | | Add support for these opcodes, the conversion functions were already there albeit need some new packing stuff. Just like the tgsi version, piglit won't like it for all the same reasons, so it's disabled (UP2H passes piglit arb_shader_language_packing tests, albeit since PK2H won't due those rounding differences I don't know if that one works or not as the piglit test is rather difficult to deal with).
* tgsi: add PK2H/UP2H supportRoland Scheidegger2016-02-022-3/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | The util functions handle the half-float conversion. Note that piglit won't like it much due to: a) The util functions use magic float mul conversion but when run inside softpipe/llvmpipe, denorms are flushed to zero, therefore when the conversion is from/to f16 denorm the result will be zero. This is a bug which should be fixed in these functions (should not rely on denorms being available), but will happen elsewhere just the same (e.g. conversion to f16 render targets). b) The util functions use trunc round mode rather than round-to-nearest. This is NOT a bug (as it is a d3d10 requirement). This will result of rounding not representable finite values to MAX_F16 rather than INFINITY. My belief is the piglit tests are wrong here but it's difficult to tell (generally glsl rounding mode is undefined, however I'm not sure if rounding mode might need to be consistent for different operations). Nevertheless, for gl it would be better to use round-to-nearest, but using different rounding for GL and d3d10 is an unsolved problem (as it affects things like conversion to f16 render targets, clear colors, this shader opcode). Hence for now don't enable the cap bit (so the code is unused).

* llvmpipe: drop scissor planes early if the tri is fully inside themRoland Scheidegger2016-02-022-69/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | If the tri is fully inside a scissor edge (or rather, we just use the bounding box of the tri for the comparison), then we can drop these additional scissor "planes" early. We do not even need to allocate space for them in the tri. The math actually appears to be slightly iffy due to bounding boxes being rounded, but it doesn't matter in the end. Those scissor rects are costly - the 4 planes from the scissor are already more expensive to calculate than the 3 planes from the tri itself, and it also prevents us from using the specialized raster code for small tris. This helps openarena performance by about 8% or so. Of course, it helps there that while openarena often enables scissoring (and even moves the scissor rect around) I have not seen a single tri actually hit the scissor rect, ever. v2: drop individual scissor edges, and do it earlier, not even allocating space for them. v3: help the compiler a bit with simpler code, suggested by Brian.

* llvmpipe: use vector loads for (optimized) tri raster funcsRoland Scheidegger2016-02-022-37/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | When we switched to 64bit rasterization, we could no longer use straight aligned loads for loading the plane data. However, what the code actually does for loading 3 planes, is 12 scalar loads + 9 unpacks, and then there's another 8 unpacks for the transpose we need (!). It would be possible to do the (scalar) loads of course already transposed (at least saving the additional unpacks), however instead just use (un)aligned vector loads, and recalculate the eo values, which is much less instructions (note in case of the triangle_32_3_4 case, the eo values are not even used, making the scalar loads + unpacks for them all the more pointless). This drops execution time of the triangle_32_3_4 function considerably, albeit it doesn't really make a measurable difference (for small tris we're essentially limited by vertex throughput in any case), for triangle_32_3_16 it's essentially noise (the loop is more costly than the initial code there). (I'm thinking about just ditching storing the eo values in the plane data, so could switch back to using aligned planes, however right now they are still used in the other raster functions dealing with planes with scalar code. Also not touching the ppc code, might not be that bad there in any case.) Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | The existing code used ssse3, and because it isn't compiled in a separate file compiled with that, it is usually not used (that, of course, could be fixed...), whereas sse2 is always present at least with 64bit builds.

* st/mesa: treat a write as a read for range purposesIlia Mirkin2016-02-011-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use this logic to detect live ranges and then do plain renaming across the whole codebase. As such, to prevent WaW hazards, we have to treat a write as if it were also a read. For example, the following sequence was observed before this patch: 13: UIF TEMP[6].xxxx :0 14: ADD TEMP[6].x, CONST[6].xxxx, -IN[3].yyyy 15: RCP TEMP[7].x, TEMP[3].xxxx 16: MUL TEMP[3].x, TEMP[6].xxxx, TEMP[7].xxxx 17: ADD TEMP[6].x, CONST[7].xxxx, -IN[3].yyyy 18: RCP TEMP[7].x, TEMP[3].xxxx 19: MUL TEMP[4].x, TEMP[6].xxxx, TEMP[7].xxxx While after this patch it becomes: 13: UIF TEMP[7].xxxx :0 14: ADD TEMP[7].x, CONST[6].xxxx, -IN[3].yyyy 15: RCP TEMP[8].x, TEMP[3].xxxx 16: MUL TEMP[4].x, TEMP[7].xxxx, TEMP[8].xxxx 17: ADD TEMP[7].x, CONST[7].xxxx, -IN[3].yyyy 18: RCP TEMP[8].x, TEMP[3].xxxx 19: MUL TEMP[5].x, TEMP[7].xxxx, TEMP[8].xxxx Most importantly note that in the first example, the second RCP is done on the result of the MUL while in the second, the second RCP should have the same value as the first. Looking at the GLSL source, it is apparent that both of the RCP's should have had the same source. Looking at what's going on, the GLSL looks something like float tmin_8; float tmin_10; tmin_10 = tmin_8; ... lots of code ... tmin_8 = tmpvar_17; ... more code that never looks at tmin_8 ... And so we end up with a last_read somewhere at the beginning, and a first_write somewhere at the bottom. For some reason DCE doesn't remove it, but even if that were fixed, DCE doesn't handle 100% of cases, esp including loops. With the last_read somewhere high up, we overwrite the previously correct (and large) last_read with a low one, and then proceed to decide to merge all kinds of junk onto this temp. Even if that weren't the case, and there were just some writes after the last read, then we might still overwrite a merged value with one of those. As a result, we should treat a write as a last_read for the purpose of determining the live range.

* nv50/ir: fix false global CSE on instructions with multiple defsIlia Mirkin2016-01-301-0/+2
| | | | | | | | | | | | | | | | | | | | | If an instruction has multiple defs, we have to do a lot more checks to make sure that we can move it forward. Among other things, various code likes to do a, b = tex() if () c = a else c = b which means that a single phi node will have results pointing at the same instruction. We obviously can't propagate the tex in this case, but properly accounting for this situation is tricky. Just don't try for instructions with multiple defs.

* nv50,nvc0: fix buffer clearing to respect engine alignment requirementsIlia Mirkin2016-01-302-52/+247
| | | | | | | | | | | | | | | It appears that the nvidia render engine is quite picky when it comes to linear surfaces. It doesn't like non-256-byte aligned offsets, and apparently doesn't even do non-256-byte strides. This makes arb_clear_buffer_object-unaligned pass on both nv50 and nvc0. As a side-effect this also allows RGB32 clears to work via GPU data upload instead of synchronizing the buffer to the CPU (nvc0 only).
