2010-10-09gallivm: optimize soa linear clamp to edge wrap mode a bitRoland 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...
2010-10-09gallivm: avoid unnecessary URem in linear wrap repeat caseRoland 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).
2010-10-09gallivm: more linear tex wrap mode calculation simplificationRoland 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.
2010-10-09gallivm: optimize some tex wrap mode calculations a bitRoland 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.
2010-10-09gallivm: replace sub/floor/ifloor combo with ifloor_fractRoland Scheidegger
2010-10-09gallivm: faster iround implementation for sse2Roland 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.
2010-10-09gallivm: fix trunc/itrunc commentRoland Scheidegger
trunc of -1.5 is -1.0 not 1.0...
2010-10-08i915: Silence unused variable warning in non-debug builds.Vinson Lee
Fixes this GCC warning. i830_vtbl.c: In function 'i830_assert_not_dirty': i830_vtbl.c:704: warning: unused variable 'i830'
2010-10-08glsl: Remove const decoration from inlined function parametersIan Romanick
The constness of the function parameter gets inlined with the rest of the function. However, there is also an assignment to the parameter. If this occurs inside a loop the loop analysis code will get confused by the assignment to a read-only variable. Fixes bugzilla #30552. NOTE: this is a candidate for the 7.9 branch.

2010-10-08glsl: Add parser support for GL_ARB_explicit_attrib_location layoutsIan Romanick
Only layout(location=#) is supported. Setting the index requires GLSL 1.30 and GL_ARB_blend_func_extended.

This will ease adding non-bit fields in the near future.

2010-10-08i965: Add register coalescing to the new FS backend.Eric Anholt
Improves performance of my GLSL demo 14.3% (+/- 4%, n=4) by eliminating the moves used in ir_assignment and ir_swizzle handling. Still 16.5% to go to catch up to the Mesa IR backend, presumably because instructions are almost perfectly mis-scheduled now.
2010-10-08i965: Enable attribute swizzling (repositioning) in the gen6 SF.Eric Anholt
We were trying to remap a fully-filled array down to only handing the WM the components it uses. This is called attribute swizzling, and if you don't enable it you just get 1:1 mappings of inputs to outputs. This almost fixes glsl-routing, except for the highest gl_TexCoord[] indices.
2010-10-08i965: Fix new FS gen6 interpolation for sparsely-populated arrays.Eric Anholt
We'd overwrite the same element twice.
2010-10-08i965: Fix gen6 WM push constants updates.Eric Anholt
We would compute a new buffer, but never point the hardware at the new buffer. This partially fixes glsl-routing, as now it get the updated uniform for which attribute to draw.
2010-10-08gallivm: Help for combined extraction and broadcasting.José Fonseca
Doesn't change generated code quality, but saves some typing.
2010-10-08llvmpipe: First minify the texture size, then broadcast.José Fonseca
2010-10-08gallivm: 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.
2010-10-08i965: Handle swizzles in the addition of YUV texture constants.Eric Anholt
If someone happened to land a set in a different swizzle order, we would have assertion failed.
2010-10-08i965: Drop the check for YUV constants in the param list.Eric Anholt
_mesa_add_unnamed_constant() already does that.
2010-10-08i965: Drop the check for duplicate _mesa_add_state_reference.Eric Anholt
_mesa_add_state_reference does that check for us anyway.
2010-10-08mesa: Simplify a bit of _mesa_add_state_reference using memcmp.Eric Anholt
2010-10-08gallivm: Warn when doing inefficient integer comparisons.José Fonseca

2010-10-08gallivm: round rather than truncate in new 4x4f->1x16ub conversion pathKeith Whitwell
2010-10-08gallivm: Use the wrappers for SSE pack intrinsics.José Fonseca
Fixes assertion failures on LLVM 2.6.
2010-10-08gallivm: special case conversion 4x4f to 1x16ubKeith Whitwell
Nice reduction in the number of operations required for final color output in many shaders.
2010-10-08llvmpipe: avoid overflow in triangle cullingKeith Whitwell
Avoid multiplying fixed-point values. Calculate triangle area in floating point use that for culling. Lift area calculations up a level as we are already doing this in the triangle_both() case. Would like to share the calculated area with attribute interpolation, but the way the code is structured makes this difficult.
2010-10-08llvmpipe: fail gracefully on oom in scene creationKeith Whitwell
