2009-04-14mesa: remove unused matrixType param from ctx->Driver.UniformMatrix() functionsBrian Paul
2009-04-14mesa: move #define for GL_PROGRAM_BINARY_LENGTH_OESBrian Paul
2009-04-14mesa: remove NV vertex/fragment program print/debug codeBrian Paul
The code in prog_print.c can be used instead.
2009-04-08mesa: minor datatype changes in optimization codeBrian Paul
2009-04-07glsl: enable the new linear scan register allocator codeBrian Paul
Seems to b working well enough to enable all the time. Optimizations can be disabled with "export MESA_GLSL=nopt" if needed.
2009-04-07glsl: don't optimize program if MESA_GLSL=noptBrian Paul
2009-04-03mesa: in mesa_add_named_constant(), avoid adding duplicate constantsBrian Paul
2009-04-03mesa: fix parameter counting in ARB vertex/fragment program parsingBrian Paul
Duplicated unnamed constants were getting counted more than once.
2009-04-03mesa: replace >= with > when testing if we've exceeded max local paramsBrian Paul
Now a program that uses 256 locals works as it should.
2009-04-03mesa: for OPCODE_LIT, use _mesa_pow() instead of exp() and log()Brian Paul
Also, s/pow/_mesa_pow/
2009-04-03mesa: rename some gl_light fields to be clearerBrian Paul
EyeDirection -> SpotDirection _NormDirection -> _NormSpotDirection
2009-04-03mesa: replace assertion with conditional in _mesa_opcode_string()Brian Paul
2009-04-03mesa: clean up formatting and use 'return' instead of 'break' consistantlyBrian Paul
2009-04-02glsl: fix segfault in linker when vertex or fragment shader was missingBrian Paul
2009-04-01glsl: implement compiling/linking of separate compilation unitsBrian Paul
A shader program may consist of multiple shaders (source code units). If we find there are unresolved functions after compiling the unit that defines main(), we'll concatenate all the respective vertex or fragment shaders then recompile. This isn't foolproof but should work in most cases.
2009-04-01mesa: use correct tex unit lod bias for TXB instructionBrian Paul
2009-04-01glsl: fix texgen state variable tokens in emit_statevars()Brian Paul
This fixes broken variable indexing into the gl_Eye/ObjectPlaneS/T/R/Q arrays. See bug 20986.
2009-04-01mesa: minor tweaks in append_token() for printing state var stringsBrian Paul
2009-03-25slang: ensure structure elements have their array length setAlan Hourihane
2009-03-20mesa: add new internal state var for window sizeBrian Paul
Actually, window width - 1, height - 1
2009-03-20mesa: linear scan register allocation for shader programsBrian Paul
This is a check-point commit; not turned on yet. Use the linear scan register allocation algorithm to re-allocate temporary registers. This is done by computing the live intervals for registers and reallocating temps with that information. For some shaders this dramatically reduces the number of temp registers needed. For the time being we give up on a few cases such as relative-indexed temps and subroutine calls (but we inline most GLSL functions anyway).
2009-03-20slang: Use _mesa_snprintf() wrapper.Michal Krol
2009-03-19slang: initialize the contextAlan Hourihane
2009-03-19slang: support uniform arraysAlan Hourihane
2009-03-19glsl: change GLSL #pragma initializationBrian Paul
Initialize the shader's pragma settings before calling the compiler. Added pragma "Ignore" fields to allow overriding the #pragma directives found in shader source code.
2009-03-19glsl: when debug pragma is on, emit comments about function calls/inlinesBrian Paul
BTW, the debug pragma syntax is "#pragma debug(on)"
2009-03-19slang: if/else/break & if/else/continue work for unrolled loopsAlan Hourihane
2009-03-18slang: redo the last commit for if/break & if/continue tests as itAlan Hourihane
wasn't good enough for deeply nested if's.
2009-03-18Revert "slang: if we detect an if/break or if/continue within a loop and we're"Alan Hourihane
This reverts commit 752296b8f311c5e3844f3ce89d17ba57224ce5ba.
2009-03-18slang: if we detect an if/break or if/continue within a loop and we'reAlan Hourihane
trying to unroll, bail, and fallback to doing the real loop.
2009-03-17mesa: update/fix doxygen commentsVinson Lee
2009-03-16mesa: Silence compiler warnings.Michal Krol
2009-03-13mesa: glUseProgram() debug code (disabled)Brian Paul
2009-03-12mesa: add support for ATI_envmap_bumpmapRoland Scheidegger
add new entrypoints, new texture format, etc translate in texenvprogram.c for drivers using the mesa-generated tex env fragment program also handled in swrast, but not tested (cannot work due to negative texel results not handled correctly)
2009-03-11mesa: remove some last remnants of GL_MESA_program_debugBrian Paul
2009-03-10glsl: remove _slang_attach_storage() functionBrian Paul
This was used to handle both variable declarations and references to variables. Instead, just do storage allocation and assignment for declarations and references, respectively. This is a step toward better var/uniform allocation (only allocate storage for vars/uniforms that are actually referenced by the code).
2009-03-10glsl: some clean-ups, remove old assertions, add new assertionsBrian Paul
2009-03-10glsl: remove stray/unneeded totalSize assignmentBrian Paul
2009-03-10mesa: fix dumb sizeof() vs. strlen() mix-upBrian Paul
2009-03-10glsl: fix typo: s/vec4_tex1d_proj/vec4_tex_1d_proj/Brian Paul
This regression came from commit c0b59420eec5ffdf22a5919d38851c3620b97c09.
2009-03-07mesa: gl_register_file enum typedefBrian Paul
2009-03-07mesa: remove GL_MESA_program_debug extensionBrian Paul
This was never fully fleshed out and hasn't been used.
2009-03-06glsl: call the program optimizerBrian Paul
This still needs more testing bug glean and Mesa GLSL tests seem OK.
2009-03-06mesa: add new program optimizer codeBrian Paul
This is pretty simplistic for now, but helps with certain shaders.
2009-03-05mesa: added some assertionsBrian Paul
2009-03-05mesa: when printing src regs, use |reg| for absolute valueBrian Paul
And check opcode number to avoid crashing on driver-private opcodes.
2009-03-04mesa: include mfeatures.hBrian Paul
See bug 20319.
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).
2009-02-27mesa: update fragResults array in arb_output_attrib_string()Brian Paul
Plus add some comments.
2009-02-26mesa: replace old prog_instruction::Sampler field with Aux fieldBrian Paul
The i965 driver needs an extra instruction field for color output information. It was using the Sampler field for this. Use the Aux field instead. This will probaby be revisited at some point...
