* gallivm: Lower TGSI_OPCODE_MUL to fmul by defaultTom Stellard2012-12-101-2/+3
| | | | | | | This fixes a number of crashes on r600g due to the fact that lp_build_mul assumes vector types when optimizing mul to bit shifts. This bug was uncovered by 0ad1fefd6951aa47ab58a41dc9ee73083cbcf85c

| | | | | | | | | | | Support 16 (defined in LP_MAX_TGSI_CONST_BUFFERS) as opposed to 32 (as defined by PIPE_MAX_CONSTANT_BUFFERS) because that would make the jit context become unnecessarily large. v2: Bump limit from 4 to 16 to cover ARB_uniform_buffer_object needs, per Dave Airlie.

* gallivm: Fix lerping of (un)signed normalized numbers.José Fonseca2012-12-061-49/+43
| | | | | | | | | | | | | | | | | | Several issues actually: - Fix a regression in unsigned normalized in the rescaling [0, 255] to [0, 256] - Ensure we use signed shifts where appropriate (instead of unsigned shifts) - Refactor the code slightly -- move all the logic inside lp_build_lerp_simple().

* gallivm: Re-add the kludge for lp_build_lerp of fixed point types.José Fonseca2012-12-041-1/+5
| | | | | | | I removed it in commit 7d44d354bdba853e453ce3991396e2b0933468f4 but texture sample code still relies on it. Not sure how to this cleanly, so put it pack for now.
* gallivm: Generalize lp_build_mul and lp_build_lerp for signed normalized types.José Fonseca2012-12-041-92/+82
| | | | | | | | This fixes fdo bug 57755 and most of the failures of piglit fbo-blending-formats GL_EXT_texture_snorm. GL_INTENSITY_SNORM is still failing, but problem is probably elsewhere, as GL_R8_SNORM works fine.

* gallivm: drop border wrap clamping codeRoland Scheidegger2012-12-011-33/+16
| | | | | | | | | | | | | | | | | | | | | The border clamping code is unnecessary, since we don't care if a wrapped coord value is -1 or <-1 (same for length vs. >length), in either case the border handling code will mask out the offset and replace the texel value with the border color. Note that technically this is not entirely correct. Omitting clamping on the float coords means that flt->int conversion may result in undefined values for values of very large magnitude. However there's no reason we should honor this here since: a) we don't care for that for ordinary wrap modes in the aos code when converting coords and the problem is worse there (as we've got only effectively 24 instead of 32bits) b) at least in some cases the clamping was done already in int space hence doing nothing to fix that problem. c) with sse2 flt->int conversion with such values results in 0x80000000 which is just perfect (for clamp to border - not so much for the ordinary clamp to edge).

* gallivm: support array texturesRoland Scheidegger2012-11-296-65/+103
| | | | | | | | | | | | | Support 1d and 2d array textures (including shadow samplers), and (as a side effect mostly) also shadow cube samplers. Seems to pass the relevant piglit tests both for sampling and rendering to (though some require version overrides). Since we don't support render target indices rendering to array textures is still restricted to a single layer at a time. Also, the min/max layer in the sampler view (which is unnecessary for GL) is ignored (always use all layers). Reviewed-by: José Fonseca <[email protected]>

* gallivm: fix rsqrt failuresRoland Scheidegger2012-10-121-8/+41
| | | | | | | | | | | | | | | | | | | | | | | | | lp_build_rsqrt initially did not do any newton-raphson step. This meant that precision was only ~11 bits, but this handled both input 0.0 and +infinity correctly. It did not however handle input 1.0 accurately, and denormals always generated infinity result. Doing a newton-raphson step increased precision significantly (but notably input 1.0 still doesn't give output 1.0), however this fails for inputs 0.0 and infinity (both result in NaNs). Try to fix this up by using cmp/select but since this is all quite fishy (and still doesn't handle denormals) disable for now. Note that even with workarounds it should still have been faster since the fallback uses sqrt/div (which both use the usually unpipelined and slow divider hw). Also add some more test values to lp_test_arit and test lp_build_rcp() too while there. v2: based on José's feedback, avoid hacky infinity definition which doesn't work with msvc (unfortunately using INFINITY won't cut it neither on non-c99 compilers) in lp_build_rsqrt, and while here fix up the input infinity case too (it's disabled anyway). Only test infinity input case if we have c99, and use float cast for calculating reference rsqrt value so we really get what we expect. Reviewed-by: José Fonseca <[email protected]>
