* mesa: Restore depth texture state on glPopAttrib(GL_TEXTURE_BIT).Kenneth Graunke2012-06-021-0/+8
| | | | | | | | | | | | | | | | | | According to Table 6.17 in the GL 2.1 specification, DEPTH_TEXTURE_MODE, TEXTURE_COMPARE_MODE, and TEXTURE_COMPARE_FUNC need to be restored on glPopAttrib(GL_TEXTURE_BIT). Makes a number of oglconform tests happier. v2: Make restoration conditional on the ARB_shadow and ARB_depth_texture extensions, as suggested by Brian. I'm not sure that any implementations still remain that don't support those, but why not? NOTE: This is a candidate for stable release branches.

* mesa: move gl_array_attrib::NewState to gl_array_object::NewArraysBrian Paul2012-04-201-7/+0
| | | | | | | | The field wasn't actually used before and it's not used now either. But this is a more logical place for it and will hopefully allow doing smarter draw/array validation (per array object) in the future. Reviewed-by: Mathias Fröhlich <[email protected]>
* mesa,vbo: properly detect when vertex arrays need to be recalculatedMarek Olšák2012-04-191-3/+0
| | | | | | | | | | | | | | | | | | | This moves the RebindArrays flag into the vbo module, consolidates the code, and adds missing vbo_draw_method calls. Also with this change, the vertex arrays are not needlessly recalculated twice. The issue with the old code was: - If recalculate_input_bindings updates vp_varying_inputs, _NEW_ARRAY is set. - _mesa_update_state is called and the vp_varying_inputs change causes regeneration of the fixed-function shaders, which also sets _NEW_PROGRAM. - The occurence of either _NEW_ARRAY or _NEW_PROGRAM sets the recalculate_inputs flag to TRUE again. - The new code sets the flag to FALSE after the second _mesa_update_state, because there can't possibly be any change which would require recalculating the arrays.

* mesa: reference shared state in glPushAttrib(GL_TEXTURE_BIT)Brian Paul2012-02-011-0/+13
| | | | | | | | | | | | This fixes a dangling texture object pointer bug hit via wglShareLists(). When we push the GL_TEXTURE_BIT state we may push references to the default texture objects which are owned by the gl_shared_state object. We don't want to accidentally delete that shared state while the attribute stack references shared objects. So keep a reference to it. NOTE: This is a candidate for the 8.0 branch.

| | | | | | | | | | | | | | | | | | | | | All drivers remaining in Mesa support this extension. This extension is either required or optional features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. The existing support is already partially broken in Mesa (e.g., querying GL_TEXTURE_ENV_MODE in OpenGL ES 2.x). This patch does not change the situation in any way. It looks like the only hardware supported by Mesa that cannot do ARB_texture_env_combine is pre-NV10 NVIDA chips. It appears that these chips cannot do the GL_SUBTRACT mode. Based on looking at older copies of nvOpenGLspecs.pdf found on the net, NVIDIA never supported ARB_texture_env_combine on those chips either. This extension was previously not supported on mach64, mga (G200), r128, savage, sis, and tdfx (Voodoo Banshee and Voodoo3).

The enable function corresponds to glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3. Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0 unless GL_EXT_draw_buffers2 is enabled.
