2009-06-26	glsl: remove test for loop unrolling when we hit conditional cont/break	Brian Paul
	This is no longer needed since we added the new _slang_loop_contains_continue_or_break() function/test.
2009-06-26	glsl: checkpoint: predicate __retVal = expr with __returnFlag	Brian Paul
	The glean "function with early return (1)" test passes now.
2009-06-26	glsl: use new helper functions in _slang_gen_logical_and/or()	Brian Paul

2009-06-26	glsl: checkpoint: replace 'return' with __returnFlag=true;	Brian Paul
	Needed for "remove early returns" transformation.
2009-06-26	glsl: fix uninitialized var in _slang_gen_for_without_continue()	Brian Paul

2009-06-26	glsl: check-point: declare _returnFlag	Brian Paul

2009-06-26	glsl: use slang_generate_declaration() to consolidate some code	Brian Paul

2009-06-26	glsl: remove obsolete comment	Brian Paul

2009-06-26	glsl: implement _slang_gen_while_without_continue()	Brian Paul

2009-06-26	glsl: fix a bug involving 'continue' in 'for' loops	Brian Paul
	Need to execute the for loop's increment code before we continue. Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing loop and avoid the "cont if true" path in this situation. Plus, assorted clean-ups.
2009-06-26	glsl: use _slang_loop_contains_continue_or_break() to check for unrolling	Brian Paul
	The previous test failed for nested loops.
2009-06-26	glsl: use new _slang_loop_contains_continue() helper function	Brian Paul

2009-06-26	glsl: implement continue->break translation for do-while loops	Brian Paul

2009-06-26	glsl: remove debug code, misc clean-up	Brian Paul

2009-06-26	glsl: implement continue->break transformation for for-loops	Brian Paul

2009-06-26	glsl: don't unroll loops containing continue/break	Brian Paul
	Just search the AST in _slang_can_unroll_for_loop().
2009-06-26	Revert "slang: if/else/break & if/else/continue work for unrolled loops"	Brian Paul
	We should just check if the loop contains a continue/break in the _slang_can_unroll_for_loop() test function... This reverts commit 989856bde47d699d7e18798df4013fbf962e1d4b. Conflicts: src/mesa/shader/slang/slang_codegen.h
2009-04-01	glsl: implement compiling/linking of separate compilation units	Brian 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.
2009-03-20	slang: Use _mesa_snprintf() wrapper.	Michal Krol

2009-03-19	slang: support uniform arrays	Alan Hourihane

2009-03-19	glsl: when debug pragma is on, emit comments about function calls/inlines	Brian Paul
	BTW, the debug pragma syntax is "#pragma debug(on)"
2009-03-19	slang: if/else/break & if/else/continue work for unrolled loops	Alan Hourihane

2009-03-18	slang: redo the last commit for if/break & if/continue tests as it	Alan Hourihane
	wasn't good enough for deeply nested if's.
2009-03-18	Revert "slang: if we detect an if/break or if/continue within a loop and we're"	Alan Hourihane
	This reverts commit 752296b8f311c5e3844f3ce89d17ba57224ce5ba.
2009-03-18	slang: if we detect an if/break or if/continue within a loop and we're	Alan Hourihane
	trying to unroll, bail, and fallback to doing the real loop.
2009-03-10	glsl: remove _slang_attach_storage() function	Brian 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).
2009-03-10	glsl: some clean-ups, remove old assertions, add new assertions	Brian Paul

2009-03-10	glsl: remove stray/unneeded totalSize assignment	Brian Paul

2009-03-07	mesa: gl_register_file enum typedef	Brian Paul

2009-02-28	mesa: rename, reorder FRAG_RESULT_x tokens	Brian 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).
2009-02-20	glsl: use new IR opcodes for TEX instructions with shadow comparison	Brian 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.
2009-02-20	glsl: rename GLSL texture assembly instructions to be more legible	Brian Paul

2009-02-20	glsl: fix vec4_texp_rect IR code (need projective version)	Brian Paul

2009-02-16	glsl: silence some uninit var warnings	Brian Paul

2009-01-14	glsl: minor clean-up for rect sampler test	Brian Paul

2009-01-14	glsl: propagate pragma info down into compiler from preprocessor	Brian Paul

2009-01-14	glsl: simplify IR storage for samplers	Brian Paul
	Don't overload the Size field with the texture target, to avoid confusion.
2009-01-14	glsl: fix regression from sampler arrays commit	Alan Hourihane

2009-01-14	glsl: fix a comment typo	Alan Hourihane

2009-01-14	glsl: support sampler arrays.	Alan Hourihane

2009-01-09	glsl: make minimum struct size = 2, not 1	Brian 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.
2009-01-07	glsl: bump up MAX_FOR_LOOP_UNROLL_COMPLEXITY	Brian Paul

2009-01-07	mesa: Add _mesa_snprintf.	José Fonseca
	On Windows snprintf is renamed as _snprintf. (cherry picked from commit f8f9a1b620d31d1a59855fd502caed325d4a324f)
2009-01-07	glsl: disable some unused functions (but don't remove just yet)	Brian Paul

2009-01-07	glsl: also unroll loops with variable declarations such as "for (int i = 0; ..."	Brian Paul

2009-01-06	glsl: loop unroll adjustments	Brian Paul
	Add a "max complexity" heuristic to allow unrolling long loops with small bodies and short loops with large bodies. The loop unroll limits may need further tweaking...
2009-01-06	glsl: implement loop unrolling for simple 'for' loops	Brian Paul
	Loops such as this will be unrolled: for (i = 0; i < 4; ++i) { body; } where 'body' isn't too large. This also helps to fix the issue reported in bug #19190. The problem there is indexing vector types with a variable index. For example: vec4 v; v[2] = 1.0; // equivalent to v.z = 1.0 v[i] = 2.0; // variable index into vector!! Since the for-i loop can be unrolled, we can avoid the problems associated with variable indexing into a vector (at least in this case).
2009-01-06	mesa: Move var declaration to top of scope.	Brian Paul
	(cherry picked from commit 3740a06e28f4cd09e2a3dce2da60320aa9304df1)
2009-01-05	mesa: fix a GLSL swizzled writemask bug	Brian Paul
	This fixes cases such as: vec4 v4; vec2 v2; v4.xz.yx = v2; The last line now correctly compiles into MOV TEMP[1].xz, TEMP[0].yyxw; Helps to fix the Humus Domino demo. See bug 19189.
2008-12-31	mesa: increase max texture image units and GLSL samplers to 16	Brian Paul
	The max texture coord units is still 8. All the fixed-function paths are still limited to 8 too. But GLSL shaders can use more samplers now. Note that some texcoord-related data structures are declared to be 16 elements in size rather than 8. This just simplifies the code in a few places; the extra elements aren't accessible to the user. These changes haven't been extensively tested yet, but sanity checking has been done. It should be possible to increase the max image units/samplers to 32 without doing anything special. Beyond that we'll need longer bitfields in a few places.
