* spirv: convert some operands for bitwise shift and bitwise ops to uint32Samuel Iglesias Gonsálvez2018-05-031-0/+35
| | | | | | | | | | | | | | | | | SPIR-V allows to define the shift, offset and count operands for shift and bitfield opcodes with a bit-size different than 32 bits, but in NIR the opcodes have that limitation. As agreed in the mailing list, this patch adds a conversion to 32 bits to fix this. For more info, see: https://lists.freedesktop.org/archives/mesa-dev/2018-April/193026.html v2: - src_bit_size will have zero value for variable bit-size operands (Jason).

* spirv: Don’t check for NaN for most OpFOrd* comparisonsNeil Roberts2018-04-261-11/+6
| | | | | | | | | | | | | | | | | | | For all of the OpFOrd* comparisons except OpFOrdNotEqual the hardware should probably already return false if one of the operands is NaN so we don’t need to have an explicit check for it. This seems to at least work on Intel hardware. This should reduce the number of instructions generated for the most common comparisons. For what it’s worth, the original code to handle this was added in e062eb6415de3a. The commit message for that says that it was to fix some CTS tests for OpFUnord* opcodes. Even if the hardware doesn’t handle NaNs this patch shouldn’t affect those tests. At any rate they have since been moved out of the mustpass list. Incidentally those tests fail on the nvidia proprietary driver so it doesn’t seem like handling NaNs correctly is a priority.

| | | | | | | | | | | | The only change neccessary is to change the type of the constant used to compare against. This has been tested against the arb_gpu_shader_fp64/execution/ fs-isinf-dvec tests using the ARB_gl_spirv branch. v2: Use nir_imm_floatN_t for the constant.

* util: Include bitscan.h directlyIan Romanick2018-03-291-0/+1
| | | | | | | | | | | | | | | Previously bitset.h would include u_math.h to get bitscan.h. u_math.h lives in src/gallium/auxiliary/util while both bitset.h and bitscan.h live in src/util. Having the one file directly include another file that lives in the same directory makes much more sense. As a side-effect, several files need to directly include standard header files that were previously indirectly included. v2: Fix build break in src/amd/common/ac_nir_to_llvm.c.

* spirv: Handle doubles when multiplying a mat by a scalarNeil Roberts2018-03-141-3/+3
| | | | | | | | | | The code to handle mat multiplication by a scalar tries to pick either imul or fmul depending on whether the matrix is float or integer. However it was doing this by checking whether the base type is float. This was making it choose the int path for doubles (and presumably float16s). Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | | Before, we were just implementing it with a move, which is incorrect when the source and destination have different bitsizes. To implement it properly, we need to use the 64-bit pack/unpack opcodes. Since glslang uses OpBitcast to implement packInt2x32 and unpackInt2x32, this should fix them on anv (and radv once we enable the int64 capability). v2: make supporting non-32/64 bit easier (Jason) v3: add another assert (Jason) Fixes: b3135c3c ("anv: Advertise shaderInt64 on Broadwell and above") Signed-off-by: Connor Abbott <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

| | | | | | | | | | | | | | | | | | | | | Besides the logical operation involved, these also require that we test if the operands are ordered / unordered. For ordered operations, both operands must be ordered (and they must pass the conditional test) while for unordered operations it is sufficient if only one of the operands is unordered (or they pass the logical test).
