* i965: fix glDrawPixels Z coordinate in intel_texture_drawpixels().Brian Paul2009-01-121-4/+8
| | | | As for glBitmap, it needs to be an NDC coord in [-1,1].
* i965: fix broken glBitmap + depth testBrian Paul2009-01-121-4/+16
| | | | | | | | | When we use the do_blit_bitmap() function, it seems the fragment Z is always 1.0. If depth testing is on, that means that bitmap fragments are often occluded by other rendering. So, the bitmap doesn't appear even if rasterpos.Z==0. The fix is to use the intel_texture_bitmap() path when depth testing is on. Also, fix the incorrect Z coordinate. It needs to be an NDC value in [-1,1].
* i965: fix broken ARB fp fog optionsBrian Paul2009-01-122-52/+6
| | | | | | | Just call _mesa_append_fog_code() if the fragment program's FogOption is not GL_NONE. This allows us to remove some unnecessary i965 fog code. Note, the arbfplight.c demo can be used to test this (see DO_FRAGMENT_FOG).

* xmesa: deprecate the "XMesa" interfaceBrian Paul2009-01-107-4/+709
| | | | | Move the include/GL/xmesa*.h files to src/mesa/drivers/x11/ so they're no longer considered public.
* glsl: force creation of new scope for for-loop bodyBrian Paul2009-01-101-0/+18
| | | | | | | | | | | Fixes regression in progs/demos/convolution.c due to loop unrolling. This also allows the following to be compiled correctly: for (int i = 0; i < n; i++) { int i; ... } This fix is a bit of a hack, however. The better fix would be to change the slang_shader.syn grammar. Will revisit that...
* glsl: replace 0/1 with GL_FALSE/GL_TRUEBrian Paul2009-01-101-18/+18

* swrast: Fix GL_ATI_separate_stencilIan Romanick2009-01-091-0/+2
| | | | | | GL_ATI_separate_stencil is enabled by default for software rasterizers, but the extension functions weren't hooked up to the dispatch table.
* glsl: make minimum struct size = 2, not 1Brian Paul2009-01-091-1/+8
| | | | | | | 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.
* glsl: fix typo in the vec2 += operator functionBrian Paul2009-01-082-2/+2

* glsl: fix broken +=, -=, *=, /= operatorsBrian Paul2009-01-082-737/+786
| | | | | | | These functions need to return the final computed value. Now expressions such as a = (b += c) work properly. Also, no need to use __asm intrinsics in these functions. The resulting code is the same when using ordinary arithmetic operators and is more legible.
* mesa: fix off-by-one bug in _mesa_delete_instructions()Brian Paul2009-01-081-1/+1

* i965: Remove worrisome comment about _NEW_PROGRAM signaling fp change.Eric Anholt2009-01-071-4/+0
| | | | | Everything now depends on either BRW_NEW_FRAGMENT_PROGRAM or BRW_NEW_VERTEX_PROGRAM.
* mesa: Remove _Active and _UseTexEnvProgram flags from fragment programs.Eric Anholt2009-01-078-41/+5
| | | | | | | | There was a note in state.c about _Active deserving to die, and there were potential issues with it due to i965 forgetting to set _UseTexEnvProgram. Removing both simplifies things. Reviewed-by: Brian Paul <[email protected]>

| | | | | | | 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...
* glsl: implement loop unrolling for simple 'for' loopsBrian Paul2009-01-061-24/+205
| | | | | | | | | | | | | | | | | 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).

| | | | | | This adds all of the `mglu' symbols to the list of symbol exports for GLU. Without this patch, mangled GLU symbols are considered `internal' symbols, and calling any results in undefined references.
