There's no cap bit for this as presumably all drivers could do it trivially (but this patch does not implement it for the drivers using true hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL functionality).

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner. The patch does not regress piglit on llvmpipe and on i965 on sandy bridge.

| | | | | | | | | | | | | | | | | Draw depended on clip_plane_enable being set in the rasterizer to use clipdistance registers for clipping. That's really unfriendly because it requires that rasterizer state to have variants for every shader out there. Instead of depending on the rasterizer lets extract the info from the available state: if a shader writes clipdistance then we need to use it and we need to clip using a number of planes equal to the number of writen clipdistance components.

* draw: Fix type mismatch between draw_private.h and LLVMRichard Sandiford2013-06-101-1/+1
| | | | | | | | | | | | | | | draw_vertex_buffer declared the size field to be a size_t, but the LLVM code used an int32 instead. This caused problems on big-endian 64-bit targets, because the first 32-bit chunk of the 64-bit size_t was always 0. In one sense size_t seems like a good choice for a size, so one fix would have been to try to get the LLVM code to use the equivalent of size_t too. However, in practice, the size is taken from things like ~0 or width0, both of which are int-sized, so it seemed simpler to make the size field int-sized as well.

* gallivm: work around slow code generated for interleaving 128bit vectorsRoland Scheidegger2013-06-081-0/+22
| | | | | | | | | | | | | | | We use 128bit vector interleave for untwiddling in the blend code (with 256bit vectors). llvm generates terrible code for this for some reason, so instead of generating a shuffle for 2 128bit vectors use a extract/insert shuffle instead (it only seems to matter we're not using 128bit wide vectors for the shuffle). This decreases instruction count of the blend code generated for a rgba8 render target without blending from 169 to 113 with llvm 3.1 and from 136 to 114 in llvm 3.2/3.3, and I got a ~8% (llvm 3.1) and ~5% (3.2/3.3) performance improvement in gears.

While here, also do an effective clamp (after half subtraction) of [0,length-0.5] instead of [0, length-1] which saves an instruction (the filtering weight could be different due to this, but only if both texels point to the same max texel so it doesn't matter).
