2010-07-30llvmpipe: delete function bodies after generating machine codeZack Rusin
2010-07-29gallivm: added lp_build_assert() function to make assertions in LLVM codeBrian Paul
2010-07-29Revert "gallivm: fix lp_build_sample_offset() crash when indexing a 1-D texture"José Fonseca
This reverts commit 5f90e76c54bbf4456c977b3cbca450d7a570179e. Bad cherry-pick.
2010-07-29gallivm: fix lp_build_sample_offset() crash when indexing a 1-D textureBrian Paul
If y==NULL and y_stride==NULL it means the texture is 1D. Return zero for out_i and the offset instead of garbage.
2010-07-29llvmpipe: Avoid corrupting the FPU stack with MMX instructions on 32bit OSes.José Fonseca
Unfortunately LLVM doesn't emit EMMS itself, and there is no easy/effective way to disable MMX. http://llvm.org/bugs/show_bug.cgi?id=3287
2010-07-27gallivm: Add lp_build_select_bitwise() alternative to lp_build_select_bitwiseJosé Fonseca
When (mask & a) | (~mask & b) is meant instead of mask ? a : b
2010-07-21gallivm: replace has_indirect_addressing field with indirect_files fieldBrian Paul
Instead of one big boolean indicating indirect addressing, use a bitfield indicating which register files are accessed with indirect addressing. Most shaders that use indirect addressing only use it to access the constant buffer. So no need to use an array for temporary registers in this case.
2010-07-21gallivm: refactor code into get_indirect_offsets() functionBrian Paul
2010-07-21gallivm: added commentBrian Paul
2010-07-21gallivm: remove extraneous bracesBrian Paul
2010-07-21gallivm: no longer do indirect addressing in get_temp_ptr()Brian Paul
2010-07-21gallivm: implement correct indirect addressing of temp registersBrian Paul
As with indexing the const buffer, the ADDR reg may have totally different values for each element. Need to use a gather operation.
2010-07-21gallivm: re-org, comments for get_temp_ptr()Brian Paul
2010-07-21gallivm: rename a var to avoid compiler warningsBrian Paul
2010-07-20gallivm: fix indirect addressing of constant bufferBrian Paul
The previous code assumed that all elements of the address register were the same. But it can vary from pixel to pixel or vertex to vertex so we must use a gather operation when dynamically indexing the constant buffer. Still need to fix this for the temporary register file...
2010-07-20gallivm: added lp_build_const_int32() helperBrian Paul
2010-07-07gallivm: restore const qualifierBrian Paul
2010-07-07gallivm: fix cube map LOD computationBrian Paul
First, this undoes commit e503af4baa2c709ae5743bb278b277d3faaba076 so we use iround() in lp_build_nearest_mip_level(). Second, in lp_build_sample_general() we need to check if we're sampling a cube map before anything else. Choose the cube face and then recompute the partial derivatives of (S,T) with respect to the chosen cube face. Before, we were using the directional (S,T,R) derivatives to compute the LOD. Third, work around an apparent bug in LLVM 2.7 where setting the lod variable to a const(0) value results in bad x86 code. See comments in the code.
2010-07-06gallivm: Remove unnecessary header.Vinson Lee
2010-07-06gallivm: use trunc, not round in lp_build_nearest_mip_level()Brian Paul
Fixes fd.o bug 28036 (piglit fbo-cubemap.c regression)
2010-07-06gallivm: finish implementation of lp_build_iceil()Brian Paul
Plus fix minor error in lp_build_iceil() by tweaking the offset value. And add a bunch of comments for the round(), trunc(), floor(), ceil() functions.
2010-07-06gallivm: Use SSE4.1's BLENDV instructions for lp_build_select().José Fonseca
2010-07-06gallivm: Fix 8bit comparisons.José Fonseca
2010-07-03gallivm: Remove unnecessary headers.Vinson Lee
2010-07-02gallivm: Do 4ubyte AoS texture filtering for any format that can be expressed.José Fonseca
Except if it has only one channel, as it would take the same number of instructions.
2010-07-02gallivm: Use util_format_description::fetch_rgba_8unorm() when available.José Fonseca
2010-07-02gallivm: Support multiple pixels in lp_build_fetch_rgba_aos().José Fonseca
This allows to do the unpacking of formats that fit in 4 x unorm8 in parallel, 4 pixels at a time.
2010-07-02gallivm: Move lp_build_rgba8_to_f32_soa() to lp_bld_format_soa.cJosé Fonseca
It will be more useful here.
2010-07-02gallivm: Move gather functions to its own module.José Fonseca
They need to grow, and they provide basic functionality which is not specific to sampling.
2010-07-02gallivm: Check inputs/outputs in lp_build_conv()José Fonseca
2010-07-02gallivm: Code generate YUV format unpacking.José Fonseca
2010-07-02gallivm: Fix 4 x unorm8 -> 4 x float conversion.José Fonseca
Also fix the test.
2010-07-01gallivm: Support 4 x unorm8 in lp_build_fetch_rgba_aos().José Fonseca
Uses code and ideas from Brian Paul.
2010-07-01gallivm: Allow to conversions to/from registers of different sizes.José Fonseca
Allow for example to convert from 4 x float32 to 4 x unorm8 and vice versa. Uses code and ideas from Brian Paul.
2010-07-01gallivm: Support extended swizzles in lp_build_swizzle1_aos().José Fonseca
And rename to lp_build_swizzle_aos().
2010-07-01gallivm: Setup a global optimization pass.José Fonseca
Modules are still free to setup their own optimization passes, but for the normal case it should not be necessary.
2010-07-01llvmpipe: Remove lp_build_swizzle2_aos().José Fonseca
Unnecessary special case.
2010-06-14gallivm: Omit references to NoFramePointerElimNonLeafJosé Fonseca
It was added after 2.7.
2010-06-14gallivm: Override some of the default target options.José Fonseca
In particular: - enable LLVM <-> GDB integration for JIT code - disable frame-pointer elimination on debug/profile builds - enable fast-math.
2010-06-14gallivm: Use func_to_pointer().José Fonseca
2010-06-07gallivm: eliminate tgsi_exec.h includeKeith Whitwell
2010-06-03gallivm: Register the JIT engine with oprofile on debug/profile builds.José Fonseca
2010-06-03gallivm: Factor out the quad derivative code into a single place. Fix ddy.José Fonseca
For ddy it should be (bottom - top).
2010-06-03gallium: silence all debug_named_value related warningsJoakim Sindholt
2010-06-02gallivm: bump up LP_BUILD_FLOW_MAX_VARIABLESBrian Paul
Fixes failed assertion with piglit fbo-drawbuffers-fragcolor.c See fd.o bug 28358. With 8 color buffers + Z we need to declare 33 vars, at least.

Fixes mesa texwrap demo border with GL_CLAMP.
2010-06-02gallivm: Don't use reciprocate in lp_build_sample_wrap_linear().José Fonseca
Always clamp the scaled coordinates.
