2009-06-30mesa/dlist: fixes and improvements for material cachingKeith Whitwell
Only short-circuit material call if *all* statechanges from this call are cached. Some material calls (eg with FRONT_AND_BACK) change more than one piece of state -- need to check all of them before returning. Also, Material calls are legal inside begin/end pairs, so don't need to be as careful about begin/end state as with regular statechanges (like ShadeModel) when caching. Take advantage of this and do better caching.
2009-06-30mesa/dlist: don't cache state which may not be replayed on CallListKeith Whitwell
Statechanges which occur before the first End in a display list may not be replayed when the list is called, in particular if it is called from within a begin/end pair. Recognize vulnerable statechanges and do not use them to fill in the state cache.
2009-06-30mesa/dlist: invalidate cached dlist compile state after CallListKeith Whitwell
When compiling a display list containing a CallList, it is necessary to invalidate any assumption about the GL state after the recursive call completes.
2009-06-30Merge branch 'mesa_7_5_branch' into dlist-statechange-shortcircuitKeith Whitwell
Need this to pick up fixes for per-vertex materials.
2009-06-30mesa: remove whitespaceKeith Whitwell
2009-06-30mesa: remove dead constant pointsize code from ffvertex_prog.cKeith Whitwell
2009-06-30mesa: remove dead vertex fog code from ffvertex_prog.cKeith Whitwell
2009-06-30mesa: fix material inputs in ffvertex_prog.cKeith Whitwell
Varying material inputs were not being picked up from the same slots where the VBO code is currently placing them (GENERIC0 and above). Most often they were just being ignored.
2009-06-30mesa: fix transform_points_3d_no_rot using undefined values in %xmm0Arthur HUILLET
Signed-off-by: Arthur HUILLET <arthur.huillet@free.fr>
2009-06-30mesa: Set FLUSH_EXPLICIT_BIT flags when calling FlushMappedBufferRange.José Fonseca
As prescribed by ARB_map_buffer_range.
2009-06-30mesa/dlist: restore missing SAVE_FLUSH_VERTICES in save_ShadeModelKeith Whitwell
Reorganization of ShadeModel to avoid flushing vertices too often ended up never flushing vertices due to omitted line of code.
2009-06-30mesa/vbo: use _lookup_prim_by_nr for debuggingKeith Whitwell
Switch over to specialized enum lookup for primitives
2009-06-30mesa: add debug printer for primitive nameKeith Whitwell
Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive enum (GL_POINTS..GL_POLYGON). This avoids some annoying duplicates when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
2009-06-30mesa/dlist: shortcircuit some redundant statechanges at compile timeKeith Whitwell
Currently, state-changes in mesa display lists are more or less a verbatim recording of the GL calls made during compilation. This change introduces a minor optimization to recognize and eliminate cases where the application emits redundant state changes, eg: glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() glShadeModel( GL_FLAT ); glBegin( prim ) ... glEnd() The big win is when we can eliminate all the statechanges between two primitive blocks and combine them into a single VBO node. This commit implements state-change elimination for Material and ShadeModel only. This is enough to make a start on debugging, etc.
2009-06-29intel: added null ptr checkBrian Paul
This fixes a segfault seen with piglit's fdo20701 test.
2009-06-26glsl: check number of varying variables against the limitBrian Paul
Link fails if too many varying vars. (cherry picked from master, commit cc58fbcf2c5c88f406818db60910f537e03610d6)
2009-06-26mesa: raise MAX_VARYING (number of shader varying vars) to 16Brian Paul
16 is the limit for now because of various 32-bit bitfields. (cherry picked from master, commit 4e762395ef7e8c332c16fd0c11025cfa52763a45)
2009-06-26intel / DRI2: Additional flush of fake front-buffer to real front-bufferIan Romanick
To maintain correctness, the server will copy the real front-buffer to a newly allocated fake front-buffer in DRI2GetBuffersWithFormat. However, if the DRI2GetBuffersWithFormat is triggered by glViewport, this will copy stale data into the new buffer. Fix this by flushing the current fake front-buffer to the real front-buffer in intel_viewport. Fixes bug #22288.
2009-06-26mesa: bump version to 7.5-rc4Brian Paul
2009-06-26glsl: move/simplify error checking for 'return' statementsBrian Paul
2009-06-26glsl: overhaul 'return' statement handlingBrian Paul
A new node type (SLANG_OPER_RETURN_INLINED) is used to denote 'return' statements inside inlined functions which need special handling. All glean glsl1 tests pass for EmitContReturn=FALSE and TRUE.
2009-06-26glsl: predicate assignments according to __returnFlagBrian Paul
Fixes glean "function with early return (3)" case (when EmitContReturn=FALSE).
2009-06-26glsl: added slang_variable::is_global fieldBrian 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: 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
