* st/wgl: dummy implementation of wgl swapinterval extensionKeith Whitwell2009-07-014-0/+63
| | | | | | | Required as some applications retrieve and call these functions regardless of the fact that we don't advertise the extension and further more the results of wglGetProcAddress are NULL.
* gallium: fix the front face semanticsZack Rusin2009-07-016-20/+60
| | | | | | | | 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.
* wgl: Optimize wglGetProcAddress.José Fonseca2009-07-011-6/+6
| | | | Do linear search only if prefix matches.
* i915: Fix assertion failure on remapping a non-BO-backed VBO.Eric Anholt2009-06-301-1/+4
| | | | | | Failure to set the obj->Pointer back to null tripped up the assertion. Bug #22428. (cherry picked from commit 57a06d3a48c9af1067ec05e3ad96c58f4b9b99be)
* mesa/vbo: fix compile and replay of nodes ending in a FALLBACKKeith Whitwell2009-06-301-13/+27
| | | | | | | | | | | | | | | | | 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.

* mesa: fix material inputs in ffvertex_prog.cKeith Whitwell2009-06-301-39/+15
| | | | | | 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.
* mesa: fix transform_points_3d_no_rot using undefined values in %xmm0Arthur HUILLET2009-06-302-0/+2

* glx: plug a leakKristof Ralovich2009-06-301-0/+2
| | | | | | | | | Swrast was missing a free for the culmination of driConcatConfigs. Use free(), not _mesa_free() since we shouldn't be calling any Mesa functions from the GLX code. driConcatConfigs() should probably use regular malloc/free to be consistant but the Mesa functions just wrap the libc functions anyway.

* mesa: Set FLUSH_EXPLICIT_BIT flags when calling FlushMappedBufferRange.José Fonseca2009-06-302-9/+22
| | | | As prescribed by ARB_map_buffer_range.
* util: Set PIPE_BUFFER_USAGE_FLUSH_EXPLICIT when calling ↵José Fonseca2009-06-301-1/+3
| | | | buffer_flush_mapped_range.
* gallium: New PIPE_BUFFER_USAGE_FLUSH_EXPLICIT flag for ↵José Fonseca2009-06-303-7/+18
| | | | | | | | | | | | | | | | buffer_flush_mapped_range. When a buffer was mapped for write and no explicit flush range was provided the existing semantics were that the whole buffer would be flushed, mostly for backwards compatability with non map-buffer-range aware code. However if the buffer was mapped/unmapped with nothing really written -- something that often happens with the vbo -- we were unnecessarily assuming that the whole buffer was written. The new PIPE_BUFFER_USAGE_FLUSH_EXPLICIT flag (based from ARB_map_buffer_range 's GL_MAP_FLUSH_EXPLICIT_BIT flag) allows to clearly distinguish the legacy usage from the nothing written usage.
* intel: added null ptr checkBrian Paul2009-06-291-1/+1
| | | | This fixes a segfault seen with piglit's fdo20701 test.
* glsl: check number of varying variables against the limitBrian Paul2009-06-261-4/+9
| | | | | | Link fails if too many varying vars. (cherry picked from master, commit cc58fbcf2c5c88f406818db60910f537e03610d6)
* mesa: raise MAX_VARYING (number of shader varying vars) to 16Brian Paul2009-06-261-1/+1
| | | | | | 16 is the limit for now because of various 32-bit bitfields. (cherry picked from master, commit 4e762395ef7e8c332c16fd0c11025cfa52763a45)
* intel / DRI2: Additional flush of fake front-buffer to real front-bufferIan Romanick2009-06-261-0/+11
| | | | | | | | | | | 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.

* glsl: overhaul 'return' statement handlingBrian Paul2009-06-263-215/+212
| | | | | | | 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.

| | | | | | | | 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.
