2010-04-06gallivm: Fallback to calling util_format_description::fetch_float for any ↵José Fonseca
format we can't code LLVM IR directly.
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.
