2009-06-26glsl: code refactoring for return statementsBrian Paul
2009-06-26glsl: fix assorted regressions related to early-return-removalBrian Paul
2009-06-26glsl: comments, field reorderingBrian Paul
2009-06-26glsl: rework loop nesting codeBrian Paul
2009-06-26glsl: remove test for loop unrolling when we hit conditional cont/breakBrian Paul
This is no longer needed since we added the new _slang_loop_contains_continue_or_break() function/test.
2009-06-26glsl: checkpoint: predicate __retVal = expr with __returnFlagBrian Paul
The glean "function with early return (1)" test passes now.

2009-06-26glsl: add commentsBrian Paul
2009-06-26glsl: checkpoint: replace 'return' with __returnFlag=true;Brian Paul
Needed for "remove early returns" transformation.
2009-06-26glsl: fix up scoping for parent/children in slang_operation_copy()Brian Paul
This will need more testing, but no regressions seen so far.
2009-06-26glsl: fix uninitialized var in _slang_gen_for_without_continue()Brian Paul

2009-06-26st/mesa: query PIPE_CAP_TGSI_CONT_SUPPORTEDBrian Paul
2009-06-26glsl: implement _slang_gen_while_without_continue()Brian Paul
2009-06-26glsl: fix a bug involving 'continue' in 'for' loopsBrian 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.
2009-06-26glsl: added slang_oper_child_const()Brian Paul
2009-06-26glsl: use _slang_loop_contains_continue_or_break() to check for unrollingBrian Paul
The previous test failed for nested loops.
2009-06-26glsl: use new _slang_loop_contains_continue() helper functionBrian Paul
2009-06-26glsl: implement continue->break translation for do-while loopsBrian Paul
2009-06-26glsl: added slang_operation_literal_int/bool() helper functionsBrian Paul
2009-06-26glsl: don't allocate 0-length children array in slang_operation_copy()Brian Paul

2009-06-26glsl: added slang_assemble_ctx::EmitContReturn field, initBrian Paul
2009-06-26glsl: don't unroll loops containing continue/breakBrian Paul
Just search the AST in _slang_can_unroll_for_loop().
2009-06-26Revert "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
2009-06-26glsl: Added gl_shader_state::EmitContReturn fieldBrian Paul
This is the start of a glsl-continue-return feature branch to support a GLSL code generator option for 'continue' and 'return' statements. Some targets don't support CONT or RET statements so we'll need to try to generate code that does not use them...
2009-06-22i965: handle OPCODE_SWZ in the glsl pathRoland Scheidegger
glsl compiler will not generate OPCODE_SWZ, and as a first step it would be translated away to a MOV anyway (why?), but later internally this opcode is generated (for EXT_texture_swizzling). (cherry picked from commit 4ef1f8e3b52a06fcf58f78c9c36738531b91dbac)
2009-06-22intel: intel_texture_drawpixels() can't handle GL_DEPTH_STENCIL.Michel Dänzer
Fixes glean depthStencil test. (cherry picked from commit 3885b708fdbb7bbd5dd3a247c41fb9a75ee7c057)
2009-06-22i965: added intelFlush() call in intel_get_tex_image()Brian Paul
Fixes the render-to-texture test in progs/tests/getteximage.c (cherry picked from commit a03b349153660e449daf4f56d750f1caef23b1a5)
2009-06-22mesa: s/MAX_VERTEX_PROGRAM_ATTRIBS/MAX_NV_VERTEX_PROGRAM_INPUTS/ in NV funcsBrian Paul
(cherry picked from commit 4dc426c01627a240bd5b148c1804c45b0d5ecd6c)
2009-06-22mesa: rename MAX_VERTEX_ATTRIBS to MAX_VERTEX_GENERIC_ATTRIBSBrian Paul
Be clearer that this is the number of generic vertex program/shader attributes, not counting the legacy attributes (pos, normal, color, etc). (cherry picked from commit 4a95185c9f30c2de7a03bb1a0653f51b53b1111d)
2009-06-22mesa: s/MAX_VERTEX_PROGRAM_ATTRIBS/MAX_NV_VERTEX_PROGRAM_INPUTSBrian Paul
(cherry picked from commit d2a74d76c96957cf0294dcf40d29526621ada95e)
2009-06-22mesa: fix some potential state-restore issues in pop_texture_group()Brian Paul
Call the _mesa_set_enable() functions instead of driver functions, etc. Also, add missing code for 1D/2D texture arrays. (cherry picked from commit aac19609bfd7c950b2577489b06886c8a8097bb2)
2009-06-22vbo: return VP_NONE from get_program_mode() if running fixed-func vertex programBrian Paul
If we're running a vertex program to emulated fixed-function, we still need to treat vertex arrays/attributes as if we're in fixed-function mode. This should probably be back-ported to Mesa 7.5 after a bit more testing. (cherry picked from commit dda82137d28aba846dda73da230871c115e30aaf)
2009-06-22mesa: create/use a fallback texture when bound texture is incompleteBrian Paul
When a GLSL sampler reads from an incomplete texture it should return (0,0,0,1). Instead of jumping through hoops in all the drivers to make this happen, just create/install a fallback texture with those texel values. Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some GPU lockups when trying to sample from missing surfaces. If a binding table entry is NULL, it seems that sampling sometimes works, but not always (lockup). Todo: create a fallback texture for each type of texture target? (cherry picked from commit 3f25219c7bf0f090502489928f0f018e62c4f6cf)
2009-06-19intel: Fix other metaops versus GL_COMPILE_AND_EXECUTE dlists.Eric Anholt
Fixes oglconform zbfunc.c and pxtrans-cidraw.c, at least. (cherry picked from commit 405300bb190f516e16b704050abe3389b366ed27)
2009-06-19intel: Fix glClear behavior versus display lists.Eric Anholt
The CALL_DrawArrays was leaking the clear's primitives into the display list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which doesn't appear to leak. Fixes piglit dlist-clear test. (cherry picked from commit 64edde1004f7a69e77877bba24d315a92bcd47c8)
2009-06-19radeons: use dp4 for position invariant vertex programsRoland Scheidegger
Fixes #22181. R200 requires this since DP4 is used in hw tnl mode. R300 prefers it (should be faster due to no instruction dependencies), but both methods should be correct (when sw tcl is used though, MUL/MAD might be faster). Probably doesn't make much difference for R100 since vertex progs are executed in software anyway, but let's just keep it the same there too.
2009-06-19Always free image offsets memory when re-initializing texture image fields.Michel Dänzer
Fixes leak running compiz with direct rendering.
2009-06-18mesa: protect Elements against multiple definitionsKeith Whitwell
Mesa and gallium both have a definition of this macro
2009-06-17intel: remove extra \n from warning stringBrian Paul
(cherry picked from commit 42e9bde0fa2276b8f5bb434328eea7665794b127)
2009-06-17i965: fix 1D texture borders with GL_CLAMP_TO_BORDERRobert Ellison
With 1D textures, GL_TEXTURE_WRAP_T should be ignored (only GL_TEXTURE_WRAP_S should be respected). But the i965 hardware seems to follow the value of GL_TEXTURE_WRAP_T even when sampling 1D textures. This fix forces GL_TEXTURE_WRAP_T to be GL_REPEAT whenever 1D textures are used; this allows the texture to be sampled correctly, avoiding "imaginary" border elements in the T direction. This bug was demonstrated in the Piglit tex1d-2dborder test. With this fix, that test passes. (cherry picked from commit ab6c4fa582972e25f8800c77b5dd5b3a83afc996)
2009-06-17i965: send all warnings through _mesa_warning()Robert Ellison
One warning message: drm_i915_getparam: -22 was still being sent to fprintf(). This causes all Piglit tests to fail, even with MESA_DEBUG=0. Using _mesa_warning() to emit the message allows the general Mesa controls for messages like this to be applied. (cherry picked from commit bc3270e99f5c39544aaf831742db14796ab83a6a)
