2009-02-28mesa: rename, reorder FRAG_RESULT_x tokensBrian Paul
s/FRAG_RESULT_DEPR/FRAG_RESULT_DEPTH/ s/FRAG_RESULT_COLR/FRAG_RESULT/COLOR/ Remove FRAG_RESULT_COLH (NV half-precision) output since we never used it. Next, we might merge the COLOR and DATA outputs (COLOR0, COLOR1, etc).

2009-02-23glsl: yet another swizzled expression fixBrian Paul
This fixes swizzled conditional expressions such "(b ? p : q).x"
2009-02-23glsl: fix another swizzle-related bugBrian Paul
This fixes the case of "infinitely" nested swizzles such as EXPR.wzyx.yxwz.xxyz This doesn't appear in typical shaders but with function inlining and the compiler's internal use of swizzles it can happen. New glean glsl1 test case added for this.
2009-02-20glsl: use new IR opcodes for TEX instructions with shadow comparisonBrian Paul
Such TEX instructions will have the TexShadow flag set. The gl_program::ShadowSamplers field is now set in the linker. We missed that before.
2009-02-20glsl: rename GLSL texture assembly instructions to be more legibleBrian Paul
2009-02-20glsl: fix vec4_texp_rect IR code (need projective version)Brian Paul
2009-02-18glsl: fix link failure for variable-indexed varying output arraysBrian Paul
If the vertex shader writes to a varying array with a variable index, mark all the elements of that array as being written. For example, if the vertex shader does: for (i = 0; i < 4; i++) gl_TexCoord[i] = expr; Mark all texcoord outputs as being written, not just the first. Linking will fail if a fragment shader tries to read an input that's not written by the vertex shader. Before this fix, this linker test could fail.
2009-02-18glsl: fix a swizzle-related regressionBrian Paul
This new issue was exposed by commit 6eabfc27f19a10dfc2663e99f9560966ba1ff697
2009-02-17glsl: fix mistake in a commentBrian Paul
2009-02-17glsl: fix an array indexing bugBrian Paul
This fixes a bug found with swizzled array indexes such as in "array[index.z]" where "index" is an ivec4.

2009-02-06glsl: new MESA_GLSL env var for GLSL debugging featuresBrian Paul
Replaces the VERBOSE_GLSL, VERBOSE_GLSL_DUMP flags which only worked in debug builds. MESA_GLSL will work both in debug and non-debug builds. Also add facility to dump glUniform() calls to stdout.
2009-02-06Revert "mesa: meaningless whitespace change to see if git's working (ignore)"Brian Paul
This reverts commit b2e779988eeb595187933fe2122d86f8ccfe059c. I didn't mean to push this stuff yet. I'm having a bad git day...
2009-02-06mesa: meaningless whitespace change to see if git's working (ignore)Brian Paul
2009-02-04glsl: use _slang_var_swizzle() in a few places to simplify the code.Brian Paul
2009-02-04glsl: remove unused prototypeBrian Paul
2009-02-04glsl: replace assertion with conditional in _slang_pop_var_table()Brian Paul
We were hitting the assertion when we ran out of registers, which can happen. Also, add some additional assertions and freshen up some comments.
2009-02-02mesa: fix GLSL issue preventing use of all 16 generic vertex attributesBrian Paul
Only 15 actually worked before since we always reserved generic[0] as an alias for vertex position. The case of vertex attribute 0 is tricky. The spec says that there is no aliasing between generic vertex attributes 0..MAX_VERTEX_ATTRIBS-1 and the conventional attributes. But it also says that calls to glVertexAttrib(0, v) are equivalent to glVertex(v). The distinction seems to be in glVertex-mode versus vertex array mode. So update the VBO code so that if the shader uses generic[0] but not gl_Vertex, route the attribute data set with glVertex() to go to shader input generic[0]. No change needed for the glDrawArrays/Elements() path. This is a potentially risky change so regressions are possible. All the usual tests seem OK though.
2009-02-02glsl: update program->InputsRead when referencing input attributesBrian Paul
This info will be used in the linker for allocating generic vertex attribs.

2009-01-12glsl: better fix for for-loop scope issue (commit ↵Brian Paul

2009-01-10glsl: force creation of new scope for for-loop bodyBrian Paul
Fixes regression in progs/demos/convolution.c due to loop unrolling. This also allows the following to be compiled correctly: for (int i = 0; i < n; i++) { int i; ... } This fix is a bit of a hack, however. The better fix would be to change the slang_shader.syn grammar. Will revisit that...
2009-01-10glsl: replace 0/1 with GL_FALSE/GL_TRUEBrian Paul
2009-01-09glsl: make minimum struct size = 2, not 1Brian Paul
1-component structs such as "struct foo { float x; }" could get placed at any position within a register. This caused some trouble computing the field offset which assumed all struct objects were placed at R.x. It would be unusual to hit this case in normal shaders.
2009-01-09glsl: fix typo in the vec2 += operator functionBrian Paul
2009-01-09glsl: fix broken +=, -=, *=, /= operatorsBrian Paul
These functions need to return the final computed value. Now expressions such as a = (b += c) work properly. Also, no need to use __asm intrinsics in these functions. The resulting code is the same when using ordinary arithmetic operators and is more legible.
2009-01-09glsl: pass GLcontext::Extension info down into GLSL preprocessorBrian Paul
Now the #extension directives can be handled properly.
