We could use single 1 bit conditions for scalar masks, but a lot of code
expects masks. The compiler easily optimzes away masks
extensions/truncations so consistency is preferable.
We can revisit this when LLVM backends have more support for vector
conditions.

Without the validation, the function might draw with outdated textures.

st_DrawTex calls util_draw_vertex_buffer. Since
ac4abaecd5f52e416c89bfe19b34ed7f4e014b21, the caller is expected to set
vertex elements before calling.

Extensions were enabled in both st/mesa and st/dri, with st/dri completely
overriding the decisions of st/mesa and exposing even the extensions claimed
to be unsupported by a pipe driver.
This commit moves the differences between the two to st/mesa and removes
the responsibilty of advertising extensions from st/dri.

Memory for xm_dt was allocated twice.

The new lp_build_sample_general() function will handle all sampling
modes for all texture types. Still incomplete, but a few additional
sampling modes are now supported.
1D textures should work and most of the code for 3D textures is in place.
No support for cube maps yet. No support for different min/mag filters.

Time to start consolidating some code...

Reemitting dirty states on flush causes problems if the GL context
isn't fully consistent when we get to it. It didn't serve any specific
purpose, so, use nouveau_bo_state_emit instead.

Saves an instruction in PINTERP, LINTERP, and PIXEL_W from
brw_wm_glsl.c For non-GLSL it isn't used yet because the deltas have
to be laid out differently.

Fixes hangs with texturing in the non-GLSL path since

Instead of testing each component individually, we can test the entire
vector at once.

makes loops work

Fixes glean/logicOp (regressed after introducing hw accelerated support for ReadPixels)
|

Fixes #23532 and piglit/fbo-nodepth-test piglit/fbo-nostencil-test

Fixes piglit/fbo-blit and wine d3d9 unit test.

Only works well with LLVM >= 2.7

See fd.o bug 26970. Also added sanity check assertions.

This would be triggered by use of sqrt() along with control flow.
Fixes piglit-fs-sqrt-branch and a bug in Yo Frankie!.

The bad response length would hang the GPU with a masked sample in a
shader using control flow. For 8-wide, the response length is always
4, and masked slots are just not written to. brw_wm_glsl.c already
allocates registers in the right locations.
Fixes piglit glsl-fs-bug25902 (fd.o bug #25902).

If the user calls glRenderBufferTexture(texture=N) but texture N
doesn't name an existing texture, raise GL_INVALID_ENUM.
Plus, add a comment about some questionable error checking code in
framebuffer_texture(). Ian?

This fixes a problem in glReadPixels when reading from an FBO's texture
attachment. We have a better chance at hitting a fast path for
glReadPixels now.

There was a DrawBuffer/ReadBuffer typo and we were neglecting to invert
the texture coords when copying from a window to an FBO.
Plus, add some surface dump/debug code (disabled).

We weren't inverting the textured quad when drawing into an fbo.

Could result in use of freed memory and consequently random crashes, e.g. on
screen resize.

add_dispatch (driver) and maybe get_proc_address (client) may be called before
set_dispatch is called, which results in generate_entrypoint using an unreloced
function template.

- a function cannot be both static and extension, right ?
- we should be setting the offset only if not already set, right ?
