0fd97db8b0 glsl2: Associate the GLenum for the type with builtin GLSL types. 2010-06-25 16:35:22 -07:00
Eric Anholt
bda27424cf glsl2: Use the parser state as the talloc context for dead code elimination. 
This cuts runtime by around 20% from talloc_parent() lookups.

abc4e52992 glsl2: Emit OPCODE_END at the end of the Mesa program. 
The 965 driver can now run a glsl2-generated shader!

582b73fe69 glsl2: Hook up constant parameters in ir_to_mesa. 2010-06-25 13:27:57 -07:00

ffc845a50a glsl2: Set InputsRead and OutputsWritten on the generated programs. 2010-06-25 12:52:01 -07:00

364fcd8ee1 glsl2: Start integrating ir_to_mesa.cpp into shader_api.h 
The compiler is now called by the driver, and generates program
instructions.  Parameter lists are still not set up, so the driver
chokes on it shortly thereafter.

7f2bf62d25 glsl2: Use Mesa types instead of duping them into our program.h. 2010-06-25 12:25:19 -07:00
Eric Anholt
2a3d46dd46 glsl2: Fix dependencies. (at least partially) 2010-06-25 12:23:20 -07:00

f4869f3326 glsl2: Remove files that had been imported for standalone. 2010-06-24 17:14:00 -07:00

9aa0b6d728 glsl2: Move the Mesa IR codegen into mesa/shader/ 2010-06-24 15:49:18 -07:00
Eric Anholt
bcc13b7444 Merge branch 'glsl2-head' into glsl2 
This brings in the standalone GLSL compiler that we are planning on
replacing the existing Mesa GLSL compiler.  It currently targets GLSL
1.20 and the Mesa IR.

e5cf3aadb8 glsl2: Add a README file for the new compiler. 2010-06-24 15:46:53 -07:00
Eric Anholt
2928588267 glsl2: Move the compiler to the subdirectory it will live in in Mesa. 2010-06-24 15:36:00 -07:00
Eric Anholt
0ee7d80269 Merge branch 'mesa' 
This brings in the ir_to_mesa.cpp code I've been developing to codegen
to the Mesa IR.  It does not actually generate a complete Mesa
fragment/vertex program yet.
 2010-06-24 15:27:10 -07:00
Eric Anholt
6b01b50888 Move the talloc_parent lookup down in a few hot paths. 
talloc_parent is still 80% of our runtime, but likely talloc_parent
lookups will be reduced as we improve the handling of memory
ownership.

e33c10328c Merge remote branch 'cworth/master' 
Conflicts:
	ast_to_hir.cpp
	ir.cpp

This brings in the talloc-based memory management work, so that the
compiler (almost) no longer leaks memory.

8364fc85b8 ir_to_mesa: Handle a limited subset of matrix multiplication. 
glsl-mvp.vert now generates believable code, and mesa mode fails only
5 tests that master doesn't.  I must have left out some asserts...
 2010-06-24 15:05:21 -07:00
Eric Anholt
7672064756 ir_to_mesa: Handle constant matrices. 
There's not much to it since we're not actually storing constant data yet.
 2010-06-24 15:05:21 -07:00
Eric Anholt
f4bd7f262e ir_to_mesa: Fix copy-and-wasted second argument to compare expresssion ops. 
Fixes CorrectParse2.vert assertion due to uninitialized values.
 2010-06-24 15:05:21 -07:00
Eric Anholt
4006424f5b ir_to_mesa: Don't allocate temps for swizzles. 
We do them in place by actually, you know, swizzling.
 2010-06-24 15:05:21 -07:00

a9b619bb3b ir_to_mesa: Set up storage for uniform vars. 2010-06-24 15:05:21 -07:00
Eric Anholt
554dbcce77 ir_to_mesa: Move the classes into the file now that we don't have the burg. 
At 1kloc, it doesn't look like I'll want to split the ir_to_mesa file
up even once it's feature-complete.  Move definitions closer to usage,
and prevent rebuilding the world when changing the definitions.

2401338ef8 ir_to_mesa: Remove old monoburg structure. 2010-06-24 15:05:21 -07:00
Eric Anholt
9cd8cad9f3 ir_to_mesa: Restrict dst writemasks like we did in the monoburg setup. 2010-06-24 15:05:21 -07:00
Eric Anholt
9d2b8e0b70 ir_to_mesa: Fix copy-and-wasted DIV instruction sequence. 2010-06-24 15:05:21 -07:00
Eric Anholt
0161515c39 ir_to_mesa: Remove the BURG code. 
The promise of the BURG was to recognize multi-instruction sequences
and emit reduced sequences for them.  It would have worked well for
recognizing MUL+ADD -> MAD and possibly even MIN(MAX(val, 0), 1) ->
MOV_SAT with some grammar changes.  However, that potential benefit in
making those optimizations easy is outweighed by the fragility of
monoburg, the amount of (incorrect, as I wrote it) code for using it,
and the burden it was going to cause for handling operations on
aggregate types.

224f712950 ir_to_mesa: Fix mapping of FS texcoord inputs and color output. 2010-06-24 15:05:21 -07:00
Eric Anholt
ab386f18b0 ir_to_mesa: Try to fix up the dereference handling for the visitor rework. 
One of the gstreamer shaders I play with now compiles, but input
mappings are wrong.
 2010-06-24 15:05:21 -07:00
Eric Anholt
c23c6c773a ir_to_mesa: Implement min and max expressions. 
fixes glsl-orangebook-ch06-bump.frag.

Eric Anholt
4a1bd916e7 ir_to_mesa: Fix up array indexing. 
The grammar for array_reference_vec4_vec4 was set up wrong, so we
weren't generating instructions if necessary for the array index.
 2010-06-24 15:05:20 -07:00
Eric Anholt
2ee85e20c8 ir_to_mesa: Remove stale comment about monoburg. 2010-06-24 15:05:20 -07:00

Eric Anholt
4e5e0f018b ir_to_mesa: Clean up some handling of builtins and arrays. 
Constant-index dereferences of arrays should work now.  One test is
regressed, but it should have been failing before this commit, too.
 2010-06-24 15:05:20 -07:00
Eric Anholt
64fcbbca9c ir_to_mesa: Add support for loops.
