* glsl: Fix lower_named_interface_blocks to account for dereferences of consts.Paul Berry2013-07-151-0/+2
| | | | | | | | | | | | | | | | In certain rare cases (such as those involving dereference of a literal constant array of structs), flatten_named_interface_blocks_declarations's rvalue visitor may be invoked on an ir_dereference_record whose variable_referenced() method returns NULL. Check for this case to avoid a segfault. Prevents crashes in piglit tests {vs,fs}-deref-literal-array-of-structs.

* glsl: Don't allow vertex shader input arrays until GLSL 1.50.Paul Berry2013-07-151-1/+1
| | | | | | | | | | | | | | Vertex shader inputs are not allowed to be arrays until GLSL 1.50. We were accidentally enabling them for GLSL 1.40 (although we haven't written any tests for them, so it's not clear whether they actually work). NOTE: although this is a simple bug fix, it probably isn't sensible to cherry-pick it to stable release branches, since its only effect is to cause incorrectly-written shaders to fail to compile.

* i965/vs: Gen4/5: enable front colors if back colors are writtenChris Forbes2013-07-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | Fixes undefined results if a back color is written, but the corresponding front color is not, and only backfacing primitives are drawn. Results are still undefined if a frontfacing primitive is drawn, but that's OK. The other reasonable way to fix this would have been to just pick the one color slot that was populated, but that dilutes the value of the tests. On Gen6+, the fixed function clipper and triangle setup already take care of this. Fixes 11 piglits: spec/glsl-1.10/execution/interpolation/interpolation-none-gl_Back*Color-* NOTE: This is a candidate for stable branches.

* gallivm: (trivial) use constant instead of exp2f() functionRoland Scheidegger2013-07-141-2/+3
| | | | | | | Some lame compilers can't do exp2f() and as far as I can tell they can't do exp2() (with doubles) neither so instead of providing some workaround for that (wouldn't actually be too bad just replace with pow) and since it is used with a constant only just use the precalculated constant.
* ilo: skip 3DSTATE_INDEX_BUFFER when possibleChia-I Wu2013-07-144-59/+77
| | | | | | When only the offset to the index buffer is changed, we can skip the 3DSTATE_INDEX_BUFFER if we always use 0 for the offset, and add (offset / index_size) to Start Vertex Location in 3DPRIMITIVE.
* gallivm: handle srgb-to-linear and linear-to-srgb conversionsRoland Scheidegger2013-07-136-7/+332
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | srgb-to-linear is using 3rd degree polynomial for now which should be _just_ good enough. Reverse is using some rational polynomials and is quite accurate, though not hooked into llvmpipe's blend code yet and hence unused (untested). Using a table might also be an option (for srgb-to-linear especially). This does not enable any new features yet because EXT_texture_srgb was already supported via util_format fallbacks, but performance was lacking probably due to the external function call (the table used by the util_format_srgb code may not be all that much slower on its own). Some performance figures (taken from modified gloss, replaced both base and sphere texture to use GL_SRGB instead of GL_RGB, measured on 1Ghz Sandy Bridge, the numbers aren't terribly accurate): normal gloss, aos, 8-wide: 47 fps normal gloss, aos, 4-wide: 48 fps normal gloss, forced to soa, 8-wide: 48 fps normal gloss, forced to soa, 4-wide: 47 fps patched gloss, old code, soa, 8-wide: 21 fps patched gloss, old code, soa, 4-wide: 24 fps patched gloss, new code, soa, 8-wide: 41 fps patched gloss, new code, soa, 4-wide: 38 fps So there's a performance hit but it seems acceptable, certainly better than using the fallback. Note the new code only works for 4x8bit srgb formats, others (L8/L8A8) will continue to use the old util_format fallback, because I can't be bothered to write code for formats noone uses anyway (as decoding is done as part of lp_build_unpack_rgba_soa which can only handle block type width of 32). Compressed srgb formats should get their own path though eventually (it is going to be expensive in any case, first decompress, then convert). No piglit regressions. v2: use lp_build_polynomial instead of ad-hoc polynomial construction, also since keeping both linear to srgb functions for now make sure both are compiled (since they share quite some code just integrate into the same function). v3: formatting fixes and bugfix in the complicated (disabled) linear-to-srgb path.

* gallivm: better support for fast rsqrtRoland Scheidegger2013-07-132-16/+63
| | | | | | | | | | | | | | | We had to disable fast rsqrt before because it wasn't precise enough etc. However in situations when we know we're not going to need more precision we can still use a fast rsqrt (which can be several times faster than the quite expensive sqrt). Hence introduce a new helper which does exactly that - it is probably not useful calling it in some situations if there's no fast rsqrt available so make it queryable if it's available too. v2: use fast_rsqrt consistently instead of rsqrt_fast, fix indentation, let rsqrt use fast_rsqrt.

* glsl: Make gl_TexCoord compatibility-onlyPaul Berry2013-07-121-26/+30
| | | | | | | | | | | | | | | | | | | gl_TexCoord was deprecated in GLSL 1.30. In GLSL 1.40 it was marked as ARB_compatibility-only, and in GLSL 1.50 and above it was marked as only appearing in the compatibility profile. It has never appeared in GLSL ES. However, Mesa erroneously included it in all desktop versions of GLSL, even versions 1.40 and 1.50 (which do not currently support the compatibility profile). This patch makes gl_TexCoord available in the compatibility profile (and GLSL versions 1.30 and prior) only. NOTE: although this is a simple bug fix, it probably isn't sensible to cherry-pick it to stable release branches, since its only effect is to cause incorrectly-written shaders to fail to compile.

* tgsi: rename the TGSI fragment kill opcodesBrian Paul2013-07-1232-110/+109
| | | | | | | | | | | | | | | | | | | | | TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <[email protected]>
