* state_tracker: Fix assertion failures in conditional block movs.Eric Anholt2015-01-101-31/+26
| | | | | | | | | | | | | If you had a conditional assignment of an array or struct (say, from the if-lowering pass), we'd try doing swizzle_for_size() on the aggregate type, and it would assertion fail due to vector_elements==0. Instead, extend emit_block_mov() to handle emitting the conditional operations, which also means we'll have appropriate writemasks/swizzles on the CMPs within a struct containing various-sized members. Fixes 20 testcases in es3conform on vc4. Reviewed-by: Jose Fonseca <[email protected]>

* st/mesa: For vertex shaders, don't emit saturate when SM 3.0 is unsupportedAbdiel Janulgue2014-12-082-4/+3
| | | | | | | | | | | There is a bug in the current lowering pass implementation where we lower saturate to clamp only for vertex shaders on drivers supporting SM 3.0. The correct behavior is to actually lower to clamp only when we don't support saturate which happens on drivers that don't support SM 3.0 Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Matt Turner <[email protected]> Signed-off-by: Abdiel Janulgue <[email protected]>
* mesa/st: don't use CMP / I2F for conditional assignments with native integersRoland Scheidegger2014-12-061-17/+45
| | | | | | | | | | | | | | | | | | | The original idea was to optimize away the condition by integrating it directly into the CMP instruction. However, with native integers this requires an extra I2F instruction. It is also fishy because the negation used didn't really honor ieee754 float comparison rules, not to mention the CMP instruction itself (being pretty much a legacy instruction) doesn't really have defined special float value behavior in any case. So, use UCMP and adjust the code trying to optimize the condition away accordingly (I have absolutely no idea if such conditions are actually hit or would be translated away somewhere else already). v2: cosmetic changes No piglit regressions on llvmpipe.

| | | | | | | | | | | | | | | | | Not all drivers can set gl_Layer from VS. Add a fallback that passes the instance id from VS to GS, and then uses the GS to set the layer.

* st/mesa: copy sampler_array_size field when copying instructionsBrian Paul2014-11-171-1/+6
| | | | | | | | | | | | | | | | | | The sampler_array_size field was added by "mesa/st: add support for dynamic sampler offsets". But the field wasn't getting copied in the get_pixel_transfer_visitor() or get_bitmap_visitor() functions. The count_resources() function then didn't properly compute the glsl_to_tgsi_visitor::samplers_used bitmask. Then, we didn't declare all the sampler registers in st_translate_program(). Finally, we asserted when we tried to emit a tgsi ureg src register with File = TGSI_FILE_UNDEFINED. Add the missing assignments and some new assertions to catch the invalid register sooner.

* Revert "st/mesa: set MaxUnrollIterations = 255"Marek Olšák2014-10-281-2/+1
| | | | | | | | | | | | | | | | | | This reverts commit 20836c81851e0df29a8ee9c86e5e5388738c840b. 255 is a huge number. If you have a loop with 255 iterations, unrolling it will exceed the SM3 instruction limit. Let's use the default again. The comment about a SM3 limit doesn't make sense. For SM3, we generally want 32 (default) or a lower number due to the SM3 instruction limit, which is 512 instructions. For SM4, we can try higher numbers if needed, but some shaders can end up being pretty huge and shader compilation can take more time. This fixes a shader compile failure on R500/SM3.

| | | | | | | | | | | | | The drivers not flagging primitive restart support are r300 swtcl, svga, nv30, and vc4. The point of primitive restart is to slightly reduce draw call overhead for apps by batching multiple draws. If we do an extra pass to read the index buffer and split back into multiple draws, we've entirely missed the point. This is particularly bad for drivers that otherwise have hardware IB reads, where the readback is probably uncached. Reviewed-by: Rob Clark <[email protected]>
