* glsl: check number of varying variables against the limitBrian Paul2009-05-081-4/+9
| | | | Link fails if too many varying vars.
* glsl: set vertex/fragment program Ids to aid with debuggingBrian Paul2009-05-081-0/+4
|
* mesa: more shader debug code (disabled)Brian Paul2009-05-081-0/+4
|
* mesa: be smarter about allocating vert/frag program constantsBrian Paul2009-05-061-25/+76
| | | | | | | Try to re-use constants/literals more often to make best use of the constant buffer space. See bug 21354.
* mesa: more complete fix for transform_invarient glitchesKeith Whitwell2009-05-051-2/+117
| | | | | | Add a new flag mvp_with_dp4 in the context, and use that to switch both ffvertex.c and programopt.c vertex transformation code to either DP4 or MUL/MAD implementations.
* mesa: also print program params/constants when dumping shaders to diskBrian Paul2009-05-041-0/+4

| * mesa: added _mesa_check_soa_dependencies() functionBrian Paul2009-04-292-0/+53
| | | | | | | | | | This function will check an instruction to see if there's data dependencies between the dst and src registers if executed in an SOA manner.

| * mesa: signal _NEW_PROGRAM_CONSTANTS instead of _NEW_PROGRAMBrian Paul2009-04-243-10/+11
| | | | | | | | | | Use _NEW_PROGRAM_CONSTANTS when changing constant/uniform buffer values. Binding a new program/shader sets both _NEW_PROGRAM and _NEW_PROGRAM_CONSTANTS.

* | Avoid a segfault in shader compilationRobert Ellison2009-04-271-0/+6
| | | | | | | | | | | | | | | | | | | | If a shader reaches an out-of-memory condition while adding a new function (reallocating the function list), a segfault will occur during cleanup (because the num_functions field is non-zero, but the functions pointer is NULL). This fixes that segfault by zeroing out the num_functions field if reallocation fails.

* mesa: new _NEW_PROGRAM_CONSTANTS flagBrian Paul2009-04-213-9/+7
| | | | | | | | | | | | | | | This state flag will be used to indicate that vertex/fragment program constants have changed. _NEW_PROGRAM will be used to indicate changes to the vertex/fragment shader itself, or misc related state. _NEW_PROGRAM_CONSTANTS is also set whenever a program parameter that's tracking GL state has changed. For example, if the projection matrix is in the parameter list, calling glFrustum() will cause _NEW_PROGRAM_CONSTANTS to be set. This will let to remove the need for dynamic state atoms in some drivers. For now, we still set _NEW_PROGRAM in all the places we used to. We'll no longer set _NEW_PROGRAM in glUniform() after drivers/etc have been updated.

* mesa: add switch case for GL_VERTEX_STATE_PROGRAM_NV in _mesa_new_program()Brian Paul2009-04-181-0/+1
| | | | Fixes bug seen in progs/tests/vptest1.c

* mesa: merge the prog_src_register::NegateBase and NegateAbs fieldsBrian Paul2009-04-148-82/+52
| | | | | | There's really no need for two negation fields. This came from the GL_NV_fragment_program extension. The new, unified Negate bitfield applies after the absolute value step.

* glsl: enable the new linear scan register allocator codeBrian Paul2009-04-071-3/+3
| | | | | Seems to b working well enough to enable all the time. Optimizations can be disabled with "export MESA_GLSL=nopt" if needed.

* mesa: fix parameter counting in ARB vertex/fragment program parsingBrian Paul2009-04-031-5/+2
| | | | Duplicated unnamed constants were getting counted more than once.
* mesa: replace >= with > when testing if we've exceeded max local paramsBrian Paul2009-04-031-2/+2
| | | | Now a program that uses 256 locals works as it should.

|
* glsl: implement compiling/linking of separate compilation unitsBrian Paul2009-04-015-23/+138
| | | | | | | | | 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.
* mesa: use correct tex unit lod bias for TXB instructionBrian Paul2009-04-011-2/+2

* mesa: linear scan register allocation for shader programsBrian Paul2009-03-201-21/+407
| | | | | | | | | | | | | | 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).
