106ea10d1b r600g: Use a fake reloc to sleep for fences
r300g is able to sleep until a fence completes rather than busywait because
it creates a special buffer object and relocation that stays busy until the
CS containing the fence is finished.

Copy the idea into r600g, and use it to sleep if the user asked for an
infinite wait, falling back to busywaiting if the user provided a timeout.

0aadb240e1 i965/fs: Take # of components into account in try_rewrite_rhs_to_dst.
Commit dc7f449d1a introduced a new method
for avoiding MOVs: try to rewrite the destination of the instruction
that produced the RHS so it writes into the LHS.

Unfortunately, this is not safe for swizzled texturing operations, as
they return a set of four contiguous registers.  Consider the following:

(assign (x)
        (var_ref vec_ctor_x)
        (swiz x (tex vec4 (var_ref m_sampY) (var_ref m_cordY) 0 1 ())))

In this case, the source and destination registers are equal, since
reg_offset is 0 for both.  Yet, this is only a partial move: the texture
operation generates four registers, and the LHS only covers one.

Fixes color distortion in XBMC when using GLSL shaders.

e1f9820b47 i965: Rewrite the HiZ op
This is a combination of 4 commits. The first commit rewrites the HiZ op,
and remaining three fix bugs introduced by the rewrite.

======== commit 1 ========

i965: Rewrite the HiZ op

The HiZ op was implemented as a meta-op. This patch reimplements it by
emitting a special HiZ batch. This fixes several known bugs, and likely
a lot of undiscovered ones too.

==== Why the HiZ meta-op needed to die ====

The HiZ op was implemented as a meta-op, which caused lots of trouble. All
other meta-ops occur as a result of some GL call (for example, glClear and
glGenerateMipmap), but the HiZ meta-op was special. It was called in
places that Mesa (in particular, the vbo and swrast modules) did not
expect---and were not prepared for---state changes to occur (for example:
glDraw; glCallList; within glBegin/End blocks; and within
swrast_prepare_render as a result of intel_miptree_map).

In an attempt to work around these unexpected state changes, I added two
hooks in i965:
  - A hook for glDraw, located in brw_predraw_resolve_buffers (which is
    called in the glDraw path). This hook detected if a predraw resolve
    meta-op had occurred, and would hackishly repropagate some GL state
    if necessary. This ensured that the meta-op state changes would not
    intefere with the vbo module's subsequent execution of glDraw.
  - A hook for glBegin, implemented by brwPrepareExecBegin. This hook
    resolved all buffers before entering
    a glBegin/End block, thus preventing an infinitely recurring call to
    vbo_exec_FlushVertices. The vbo module calls vbo_exec_FlushVertices to
    flush its vertex queue in response to GL state changes.

Unfortunately, these hooks were not sufficient. The meta-op state changes
still interacted badly with glPopAttrib (as discovered in bug 44927) and
with swrast rendering (as discovered by debugging gen6's swrast fallback
for glBitmap). I expect there are more undiscovered bugs. Rather than play
whack-a-mole in a minefield, the sane approach is to replace the HiZ
meta-op with something safer.

==== How it was killed ====

This patch consists of several logical components:
  1. Rewrite the HiZ op by replacing function gen6_resolve_slice with
     gen6_hiz_exec and gen7_hiz_exec. The new functions do not call
     a meta-op, but instead manually construct and emit a batch to "draw"
     the HiZ op's rectangle primitive. The new functions alter no GL
     state.
  2. Add fields to brw_context::hiz for the new HiZ op.
  3. Emit a workaround flush when toggling 3DSTATE_VS.VsFunctionEnable.
  4. Kill all dead HiZ code:
     - the function gen6_resolve_slice
     - the dirty flag BRW_NEW_HIZ
     - the dead fields in brw_context::hiz
     - the state packet manipulation triggered by the now removed
       brw_context::hiz::op
     - the meta-op workaround in brw_predraw_resolve_buffers (discussed
       above)
     - the meta-op workaround brwPrepareExecBegin (discussed above)

Note: This is a candidate for the 8.0 branch.

For all the extension entrypoints using the get_buffer() helper, they

the same error return whether target was a bad enum, or a user buffer

FlushMappedBufferRange.  This appears to be an oversight).

02962ea086 glsl: Avoid ralloc_stealing a long-lived object to a short-lived parent
In commit 6ecee54a9a a call to
talloc_reference was replaced with a call to talloc_steal. This was in
preparation for moving to ralloc which doesn't support reference
counting.

The justification for talloc_steal within token_list_append in that
commit is that the tokens are being copied already. But the copies are
shallow, so this does not work.

Fortunately, the lifetime of these tokens is easy to understand. A
token list for "replacements" is created and stored in a hash table
when a function-like macro is defined. This list will live until the
macro is #undefed (if ever).

Meanwhile, a shallow copy of the list is created when the macro is
used and the list expanded. This copy is short-lived, so is unsuitable
as a new parent.

So we can just let the original, longer-lived owner continue to own
the underlying objects and things will work.

This fixes bug #45082:

	"ralloc.c:78: get_header: Assertion `info->canary == 0x5A1106'
	failed." when using a macro in GLSL

358389fe59 mesa: reference shared state in glPushAttrib(GL_TEXTURE_BIT)
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.

This cleans up the reference counting of shared context state.
The next patch will use this to fix an actual bug.

f723df005c i965: Add a driconf option to force GLSL extension behavior to "warn".
This can be used to work around broken application behavior, like in
Unigine where it attempts to use texture arrays without declaring
either "#extension GL_EXT_texture_array : enable" or "#version 130".

20da01fecd swrast: Fix fixed-function fragment processing
On i965, _mesa_ir_link_shader is never called. As a consequence, the
current fragment program (ctx->FragmentProgram->_Current) exists but is
invalid because it has no instructions. Yet swrast continued to attempt to
use the empty program.

To avoid using the empty program, this patch 1) defines a new function,
_swrast_use_fragment_program, which checks if the current fragment program
exists and differs from the fixed function fragment program, and, when
appropriate, 2) replaces checks of the form
    if (ctx->FragmentProgram->_Current == NULL)
with
    if (_swrast_use_fragment_program(ctx))

Fixes the following oglconform regressions on i965/gen6:
    api-fogcoord(basic.allCases.log)
    api-mtexcoord(basic.allCases.log)
    api-seccolor(basic.allCases.log)
    api-texcoord(basic.allCases.log)
    blend-separate(basic.allCases)
    colorsum(basic.allCases.log)

The tests were ran with the GLXFBConfig:
    visual  x   bf lv rg d st  colorbuffer  sr ax dp st accumbuffer ms  cav
  id dep cl sp  sz l  ci b ro  r  g  b  a F gb bf th cl  r  g  b  a ns b eat

(Note: I originally believed that the hunk in
_swrast_update_fragment_program was unnecessary. But it is required to fix
blend-separate.)

Note: This is a candidate for the 8.0 branch.

This was losing bits of precision.  Fixes (with the previous commits):
piglit EXT_texture_integer/getteximage-clamping
piglit EXT_texture_integer/getteximage-clamping GL_ARB_texture_rg
oglc advanced.mipmap.upload

Regresses oglc negative.typeFormatMismatch.teximage from fail to
abort, because it's been hitting texstore for a format/type combo that
shouldn't happen.
