2009-07-07mesa: only use fallback texture when using shaders, not fixed-function (take ↵Brian Paul
two) The semantics are a little different for shaders vs. fixed-function when trying to use an incomplete texture. The fallback texture returning (0,0,0,1) should only be used with shaders. For fixed function, the texture unit is truly disabled/ignored. Fixes glean fbo test regression. (cherry picked from commit 01e16befd4809e3e93ee7855a4a5d7df9fe010d9) (cherry picked from commit 51325f44d1e7e62b47795a79f8038d10dc5bc30b) [anholt: squashed these two together from master, skipping the mess in between]

2009-07-07gallium: Fixes for clobbering stencil values in combined depth/stencil textures.Michel Dänzer
Also fix one case where a 32 bit depth value was incorrectly converted to a combined depth/stencil value.
2009-07-07gallium: Only set FRONT_STATUS_COPY_OF_BACK if there is a back buffer.Michel Dänzer
Fixes potential crash when SwapBuffers is called but there's no back buffer.
2009-07-06gallium: more fog extraction fixesZack Rusin
fix the cases when fog coord/front face/point coord are used in the same shader.
2009-07-04i965: fix fetching constants from constant buffer in glsl pathRoland Scheidegger
the driver used to overwrite grf0 then use implicit move by send instruction to move contents of grf0 to mrf1. However, we must not overwrite grf0 since it's still used later for fb write. Instead, do the move directly do mrf1 (we could use implicit move from another grf reg to mrf1 but since we need a mov to encode the data anyway it doesn't seem to make sense). I think the dp_READ/WRITE_16 functions may suffer from the same issue. While here also remove unnecessary msg_reg_nr parameter from the dataport functions since always message register 1 is used.
2009-07-04i965: Remove bad constant buffer constant-reg-already-loaded optimization.Eric Anholt
Thanks to branching, the state of c->current_const[i].index at the point of emitting constant loads for this instruction may not match the actual constant currently loaded in the reg at runtime. Fixes a regression in my GLSL program for idr's class since b58b3a786aa38dcc9d72144c2cc691151e46e3d5.
2009-07-03intel: Also update stencil bits in intel_update_wrapper().Michel Dänzer
Fixes assertion failure when binding depth/stencil texture to FBO stencil attachment.
2009-07-03mesa/shaders: fix gl_NormalMatrix state parametersKeith Whitwell
gl_NormalMatrix is the inverse transpose of the modelview matrix, but as every matrix here needs to be transposed, we end up with {MODELVIEW_MATRIX, INVERSE}.
2009-07-02mesa: Assume depth textures have a single level unless told otherwise.José Fonseca
2009-07-02mesa: s/TRUE/GL_TRUEKeith Whitwell
Fix compile breakage on Linux.
2009-07-02glapi: ensure _mesa_lookup_prim_by_nr() is not clobbered on regenerationKeith Whitwell
Propogate changes to enums.c back up to the python source.
2009-07-02Merge commit 'origin/dlist-statechange-shortcircuit' into mesa_7_5_branchKeith Whitwell
Conflicts: progs/trivial/Makefile Pull in a minimal version of statechange shortcircuiting in display list compilation. This affects only glMaterial and glShadeModel state, and includes quite a few tests to exercise various tricky cases. If this goes well, will consider extending to all state in the future.
2009-07-02mesa: ensure UsesFogFragCoord value is set for non-glsl shadersKeith Whitwell
With recent changes to support frontfacing in glsl, it is necessary to ensure that the UsesFogFragCoord value is accurate in all shaders. We were previously not setting it for fixed-function and ARB_fs shaders.
2009-06-30mesa/vbo: fix compile and replay of nodes ending in a FALLBACKKeith Whitwell
Where vbo save nodes are terminated with a call to DO_FALLBACK(), as in the case of a recursive CallList which is itself within a Begin/End pair, there two problems: 1) The display list node's primitive information was incorrect, stating the cut-off prim had zero vertices 2) On replay, we would get confused by a primitive that started in a node, but was terminated by individual opcodes. This change fixes the first problem by correctly terminating the last primitive on fallback, and the second by forcing the display list to use the Loopback path, converting all nodes into immediate-mode rendering. The loopback fix is a performance hit, but avoiding this would require a fairly large rework of this code.
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: 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.

2009-07-01mesa: Unbind depth/stencil surface from pipe_framebuffer when none is attached.José Fonseca
2009-07-01gallium: fix the front face semanticsZack Rusin
mesa allocates both frontface and pointcoord registers within the fog coordinate register, by using swizzling. to make it cleaner and easier for drivers we want each of them in its own register. so when doing compilation from the mesa IR to tgsi allocate new registers for both and add new semantics to the respective declarations.
2009-06-30i915: Fix assertion failure on remapping a non-BO-backed VBO.Eric Anholt
Failure to set the obj->Pointer back to null tripped up the assertion. Bug #22428. (cherry picked from commit 57a06d3a48c9af1067ec05e3ad96c58f4b9b99be)
2009-06-30mesa/vbo: fix compile and replay of nodes ending in a FALLBACKKeith Whitwell

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.

2009-06-26glsl: 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.
