2010-04-06gallivm: Move the global LLVM objects (module, engine, provider, target) ↵José Fonseca
into here.
2010-04-02gallivm: Add fallthrough comment at end of case statement.Vinson Lee
The code is correct. Tell Coverity that the fallthrough case is intentional.
2010-04-01llvmpipe: Support sampling from PIPE_FORMAT_R32_FLOAT.José Fonseca
2010-04-01llvmpipe: Support sampling from signed and mixed siged formats.José Fonseca
2010-03-31gallivm: convert floats to doublesZack Rusin
printf can't handle floats, convert them to doubles so that we can actually print floats.

2010-03-31gallivm: Fix USCALED translation. Minor Cleanups.José Fonseca
2010-03-31llvmpipe: Drop the aos format conversion.José Fonseca
It's unused and incomplete. Still in git history if necessary in future.
2010-03-31util: Generalize lp_format_is_rgba8 into util_format_is_rgba8_variant.José Fonseca
2010-03-30gallivm: cleanup the code (found by coverity)Zack Rusin
the condition can't be false, declerations are ok even if we don't emit any.
2010-03-29gallivm: use constant size array, added assertion checkBrian Paul
2010-03-30Merge branch 'master' into gallium-new-formatsRoland Scheidegger

2010-03-30gallium: adapt all code to the renamed depth/stencil formatsRoland Scheidegger
2010-03-29gallivm: added lp_bld_printf() functionChris Li
2010-03-29gallivm: make sure that the alloca's are the very first thing in the functionZack Rusin
otherwise mem2reg can't put them in registers
2010-03-19gallivm: simplify and clean-up Z/stencil bit mask/shift codeBrian Paul
Refactor the code into two helper functions which compute the bit mask and shift terms for Z and stencil. Plus add a bunch of new comments to explain everything.
2010-03-18gallivm: support PIPE_FORMAT_Z24S8_UNORM in depth/stencil codeBrian Paul
2010-03-18gallivm: fix broken INCR/DECR stencil modesBrian Paul
We were mistakenly using the wrong data type for stencil values before.
2010-03-18gallivm/llvmpipe: added lp_rast_shader_inputs::facing and pass throughBrian Paul
The triangle rasterizer sets this field to indicate front/back-facing. It gets passed into the generated fragment code as another parameter. Used now for stencil front/back selection but will also be used for fragment shaders in general (see TGSI_SEMANTIC_FACE). With this commit two-sided stenciling mostly works but there's still a bug or two...
2010-03-18gallivm/llvmpipe: simplify front/back stencil ref value handlingBrian Paul
Instead of passing an array, just pass two scalar values.
2010-03-18gallivm: checkpoint WIP two-sided stencil testBrian Paul
2010-03-17gallivm/llvmpipe: basic stencil testing worksBrian Paul
Most stencil demos look OK (modulo some unrelated rendering glitches). Only single-sided stencil test works at this point. There are probably some bugs to be found...
2010-03-17gallivm: added lp_build_andc()Brian Paul
2010-03-17gallivm/llvmpipe: more asst changes for stencil testingBrian Paul
2010-03-17gallivm/llmvpipe: pass stencil refs state into z/stencil build codeBrian Paul
2010-03-15gallivm: checkpoint: stencil test codeBrian Paul
2010-03-15gallivm/llvmpipe: rename some constant building functionsBrian Paul
2010-03-15gallivm: fix up some #includesBrian Paul
2010-03-15gallivm/llvmpipe: rename os_llvm.h to lp_bld.hBrian Paul
The llvm wrapper wasn't really an OS thing. Use lp_bld.h for now but we eventually should rename/re-prefix all the files/functions in the gallivm/ directory.
2010-03-15gallivm: fix typo/bug in lp_build_sgn()Brian Paul
We were never returning -1 as a result. This fixes some inverted/flipped faces with cube mapping.
2010-03-15gallivm: add min_lod==max_lod special-case code in lp_build_lod_selector()Brian Paul
When min_lod==max_lod we don't need to go through all the work of computing the lod from partial derivatives. This is hit by the mipmap generation utility code.
2010-03-15gallivm: asst clean-ups, comments, etc.Brian Paul
2010-03-15gallivm: implement minification/magnification selectionBrian Paul
Use the LOD value to determine whether to use the minification vs. magnification filter. All mipmap sampling modes work now.
2010-03-15gallivm: fix incorrect clamp in lp_build_linear_mip_levels()Brian Paul
2010-03-15gallivm: fix incorrect floor(), itrunc()Brian Paul
LLVMBuildFPTrunc() should be used for double->float conversion, not float->int conversion. There should be a better way to compute floor(), ceil(), etc that doesn't involve float->int->float conversion.
2010-03-13llvmpipe: Switch to PIPE_TEX_MIPFILTER_NONE when texture has no mipmaps.José Fonseca
2010-03-12gallivm: cube map sampling works nowBrian Paul
2010-03-12gallivm: fix bugs in nested if/then/else codegenBrian Paul
Quite a bit a hair pulling was involved...
2010-03-12gallivm: support non-vector float in lp_build_sgn()Brian Paul
2010-03-11gallivm: checkpoint WIP cubemap codeBrian Paul
2010-03-11gallivm: added lp_build_sum_vector()Brian Paul
2010-03-11gallivm: enable 3D texture samplingBrian Paul
2010-03-11gallivm/llvmpipe: replace 'int stride' with 'int row_stride[MAX_LEVELS]'Brian Paul
The stride depends on the mipmap level. Rename to row_stride to distinguish from img_stride for 3D textures. Fixes incorrect texel addressing in small mipmap levels.
2010-03-11gallivm/llvmpipe: include os_llvm.h instead of llvm-c/Core.hBrian Paul
2010-03-11gallivm: fix some bugs on the 1D texture pathsBrian Paul
2010-03-11gallivm: include tgsi_dump.h to silence warningBrian Paul
2010-03-11gallivm: move declarations to silence unused var warningsBrian Paul
2010-03-11gallivm: Use bitmasks for scalar masks.José Fonseca
We could use single 1 bit conditions for scalar masks, but a lot of code expects masks. The compiler easily optimzes away masks extensions/truncations so consistency is preferable. We can revisit this when LLVM backends have more support for vector conditions.
2010-03-11gallivm: Handle scalar types in lp_build_*_type.José Fonseca
2010-03-10gallivm: overhaul of texture sampling codeBrian Paul
The new lp_build_sample_general() function will handle all sampling modes for all texture types. Still incomplete, but a few additional sampling modes are now supported. 1D textures should work and most of the code for 3D textures is in place. No support for cube maps yet. No support for different min/mag filters.
