2010-10-09 | util: Defined M_SQRT2 when not available. | José Fonseca | |
2010-10-09 | gallivm: Handle code have ret correctly. | José Fonseca | |
Stop disassembling on unconditional backwards jumps. | |||
2010-10-09 | llvmpipe: try to be sensible about whether to branch after mask updates | Keith Whitwell | |
Don't branch more than once in quick succession. Don't branch at the end of the shader. | |||
2010-10-09 | gallivm: simpler uint8->float conversions | Keith Whitwell | |
LLVM seems to finds it easier to reason about these than our mantissa-manipulation code. | |||
2010-10-09 | gallivm: prefer blendvb for integer arguments | Keith Whitwell | |
2010-10-09 | llvmpipe: store zero into all alloca'd values | Keith Whitwell | |
Fixes slowdown in isosurf with earlier versions of llvm. | |||
2010-10-09 | gallivm: Do size computations simultanously for all dimensions (AoS). | José Fonseca | |
Operate simultanouesly on <width, height, depth> vector as much as possible, instead of doing the operations on vectors with broadcasted scalars. Also do the 24.8 fixed point scalar with integer shift of the texture size, for unnormalized coordinates. AoS path only for now -- the same thing can be done for SoA. | |||
2010-10-09 | gallivm: make use of new iround code in lp_bld_conv. | Roland Scheidegger | |
Only requires sse2 now. | |||
2010-10-09 | gallivm: optimize soa linear clamp to edge wrap mode a bit | Roland Scheidegger | |
Clamp against 0 instead of -0.5, which simplifies things. The former version would have resulted in both int coords being zero (in case of coord being smaller than 0) and some "unused" weight value, whereas now the int coords will be 0 and 1, but weight will be 0, hence the lerp should produce the same value. Still not happy about differences between normalized and non-normalized... | |||
2010-10-09 | gallivm: avoid unnecessary URem in linear wrap repeat case | Roland Scheidegger | |
Haven't looked at what code this exactly generates but URem can't be fast. Instead of using two URem only use one and replace the second one with select/add (this is what the corresponding aos code already does). | |||
2010-10-09 | gallivm: more linear tex wrap mode calculation simplification | Roland Scheidegger | |
Rearrange order of operations a bit to make some clamps easier. All calculations should be equivalent. Note there seems to be some inconsistency in the clamp to edge case wrt normalized/non-normalized coords, could potentially simplify this too. | |||
2010-10-09 | gallivm: optimize some tex wrap mode calculations a bit | Roland Scheidegger | |
Sometimes coords are clamped to positive numbers before doing conversion to int, or clamped to 0 afterwards, in this case can use itrunc instead of ifloor which is easier. This is only the case for nearest calculations unfortunately, except linear MIRROR_CLAMP_TO_EDGE which for the same reason can use a unsigned float build context so the ifloor_fract helper can reduce this to itrunc in the ifloor helper itself. | |||
2010-10-09 | gallivm: replace sub/floor/ifloor combo with ifloor_fract | Roland Scheidegger | |
2010-10-09 | gallivm: faster iround implementation for sse2 | Roland Scheidegger | |
sse2 supports round to nearest directly (or rather, assuming default nearest rounding mode in MXCSR). Use intrinsic to use this rather than round (sse41) or bit manipulation whenever possible. | |||
2010-10-09 | gallivm: fix trunc/itrunc comment | Roland Scheidegger | |
trunc of -1.5 is -1.0 not 1.0... | |||
2010-10-08 | gallivm: Remove unnecessary header. | Vinson Lee | |
2010-10-08 | gallivm: Help for combined extraction and broadcasting. | José Fonseca | |
Doesn't change generated code quality, but saves some typing. | |||
2010-10-08 | llvmpipe: First minify the texture size, then broadcast. | José Fonseca | |
2010-10-08 | gallivm: Move into the as much of the second level code as possible. | José Fonseca | |
Also, pass more stuff trhough the sample build context, instead of arguments. | |||
2010-10-08 | gallivm: Warn when doing inefficient integer comparisons. | José Fonseca | |
2010-10-08 | gallivm: round rather than truncate in new 4x4f->1x16ub conversion path | Keith Whitwell | |
2010-10-08 | gallivm: Use the wrappers for SSE pack intrinsics. | José Fonseca | |
Fixes assertion failures on LLVM 2.6. | |||
2010-10-08 | gallivm: special case conversion 4x4f to 1x16ub | Keith Whitwell | |
Nice reduction in the number of operations required for final color output in many shaders. | |||
2010-10-08 | gallivm: Implement brilinear filtering. | José Fonseca | |
2010-10-08 | gallivm: Fix copy'n'paste typo in previous commit. | José Fonseca | |
2010-10-08 | gallivm: Clamp mipmap level and zero mip weight simultaneously. | José Fonseca | |
2010-10-08 | gallivm: Use lp_build_ifloor_fract for lod computation. | José Fonseca | |
Forgot this one before. | |||
2010-10-08 | gallivm: Don't compute the second mipmap level when frac(lod) == 0 | José Fonseca | |
2010-10-08 | gallivm: Simplify lp_build_mipmap_level_sizes' interface. | José Fonseca | |
2010-10-08 | gallivm: Do not do mipfiltering when magnifying. | José Fonseca | |
If lod < 0, then invariably follows that ilevel0 == ilevel1 == 0. | |||
2010-10-07 | gallivm: Vectorize the rho computation. | José Fonseca | |
2010-10-06 | util: Cleanup util_pack_z_stencil and friends. | José Fonseca | |
- Handle PIPE_FORMAT_Z32_FLOAT packing correctly. - In the integer version z shouldn't be passed as as double. - Make it clear that the integer versions should only be used for masks. - Make integer type sizes explicit (uint32_t for now, although uint64_t will be necessary later to encode f32_s8_x24). | |||
2010-10-06 | gallivm: Compute lod as integer whenever possible. | José Fonseca | |
More accurate/faster results for PIPE_TEX_MIPFILTER_NEAREST. Less FP <-> SI conversion overall. | |||
2010-10-06 | gallivm: Only apply min/max_lod when necessary. | José Fonseca | |
2010-10-06 | gallivm: don't apply zero lod_bias | Keith Whitwell | |
2010-10-06 | gallivm: Combined ifloor & fract helper. | José Fonseca | |
The only way to ensure we don't do redundant FP <-> SI conversions. | |||
2010-10-06 | gallivm: Fast implementation of iround(log2(x)) | José Fonseca | |
Not tested yet, but should be correct. | |||
2010-10-06 | gallivm: Use a faster (and less accurate) log2 in lod computation. | José Fonseca | |
2010-10-06 | gallivm: Take the type signedness in consideration in round/ceil/floor. | José Fonseca | |
2010-10-05 | pb: fix numDelayed accounting | Dave Airlie | |
we weren't decreasing when removing from the list. | |||
2010-10-05 | pb: don't keep checking buffers after first busy | Dave Airlie | |
If we assume busy buffers are added to the list in order its unlikely we'd fine one after the first busy one that isn't busy. | |||
2010-10-04 | draw: added userclip planes and updated variant_key | delphi | |
2010-09-30 | draw: check for null sampler pointers | Brian Paul | |

2010-09-30 | gallivm: added some comments | Brian Paul | |
2010-09-30 | Revert "Prefer intrinsics to handrolled atomic ops." | Tom Fogal | |
This reverts commit 5f66b340aa49c6bc8d0acb2d1a6f8e9a7ef2cb2e, quickly fixing 30514. | |||
2010-09-30 | Prefer intrinsics to handrolled atomic ops. | Tom Fogal | |
2010-09-30 | Implement x86_64 atomics for compilers w/o intrinsics. | Tom Fogal | |
Really old gcc's (3.3, at least) don't have support for the intrinsics we need. This implements a fallback for that case. | |||
2010-09-30 | gallivm: check for level=0 case in lp_build_minify() | Brian Paul | |
This lets us avoid the shift and max() operations. | |||
2010-09-30 | gallivm: More comprehensive border usage logic. | José Fonseca | |
2010-09-30 | gallium/util: remove duplicated include | Nicolas Kaiser | |
Remove duplicated include. Signed-off-by: Brian Paul <brianp@vmware.com> |
