f7848574b3 i965/gen6/blorp: Emit more flushes to workaround hangs
This is a squash of three related cherry-picks from master.

[PATCH 1/3]

  i965/gen6/blorp: Set need_workaround_flush immediately after primitive

  This patch makes the workaround code in gen6 blorp follow the pattern
  established in the regular draw path. It shouldn't result in any
  behavioral change.

  On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim()
  and gen6_blorp_emit_primitive().  brw_emit_prim() sets
  need_workaround_flush immediately after emitting the primitive, but
  blorp does not. Blorp sets need_workaround_flush at the bottom of
  brw_blorp_exec().

  This patch moves the need_workaround_flush from brw_blorp_exec() to
  gen6_blorp_emit_primitive().  There is no need to set
  need_workaround_flush in gen7_blorp_emit_primitive() because the
  workaround applies only to gen6.

[PATCH 2/3]

  i965/gen6/blorp: Set need_workaround_flush at top of blorp

  Unconditionally set brw->need_workaround_flush at the top of gen6 blorp
  state emission.

  The art of emitting workaround flushes on Sandybridge is mysterious and
  not fully understood. Ken and I believe that
  intel_emit_post_sync_nonzero_flush() may be required when switching from
  regular drawing to blorp.  This is an extra safety measure to prevent
  undiscovered difficult-to-diagnose gpu hangs.

  I verified that on ChromeOS, pre-patch, need_workaround_flush was not
  set at the top of blorp, as Paul expected. To verify, I inserted the
  following debug code at the top of gen6_blorp_exec(), restarted the ui,
  and inspected the logs in /var/log/ui. The abort gets triggered so early
  that the browser never appears on the display.

      static void
      gen6_blorp_exec(...)
      {
          if (!brw->need_workaround_flush) {
              fprintf(stderr, "chadv: %s:%d\n", __FILE__, __LINE__);
              abort();
          }
          ...
      }

[PATCH 3/3]

  i965/gen6/blorp: Remove redundant HiZ workaround

  Commit 1a92881 added extra flushes to fix a HiZ hang in
  WebGL Google Maps. With the extra flushes emitted by the previous two
  patches, the flushes added by 1a92881 are redundant.

  Tested with the same criteria as in 1a92881: by zooming in and out
  continuously for 2 hours on Sandybridge Chrome OS (codename
  Stumpy) without a hang.

df62691a02 draw: fix incorrect vertex size computation in LLVM drawing code
We were calling draw_total_vs_outputs() too early.  The call to
draw_pt_emit_prepare() could result in the vertex size changing.
So call draw_total_vs_outputs() after draw_pt_emit_prepare().

This fix would seem to be needed for the non-LLVM code as well,
but it's not obvious.  Instead, I added an assertion there to
try to catch this problem if it were to occur there.

fe2678accd glsl: Fix chained assignments of vector channels.
Simple shaders such as:

    void splat(vec2 v, float f) {
        v[0] = v[1] = f;
    }

failed to compile with the following error:
error: value of type vec2 cannot be assigned to variable of type float

First, we would process v[1] = f, and transform:
LHS: (expression float vector_extract (var_ref v) (constant int (1)))
RHS: (var_ref f)
into:
LHS: (var_ref v)
RHS: (expression vec2 vector_insert (var_ref v) (constant int (1))
                 (var_ref f))

Note that the LHS type is now vec2, not a float.  This is surprising,
but not the real problem.

After emitting assignments, this ultimately becomes:
(declare (temporary) vec2 assignment_tmp)
(assign (xy)
  (var_ref assignment_tmp)
  (expression vec2 vector_insert (var_ref v) (constant int (1))
              (var_ref f)))
  (assign (xy) (var_ref v) (var_ref assignment_tmp))

We would then return (var_ref assignment_tmp) as the rvalue, which has
the wrong type---it should be float, but is instead a vec2.

To fix this, we simply return (vector_extract (var_ref assignment_temp)
<the appropriate channel>) to pull out the desired float value.

Fixes Piglit's chained-assignment-with-vector-constant-index.vert and
chained-assignment-with-vector-dynamic-index.vert tests.

0fd4cf4bf8 mesa: Add COMPRESSED_RGBA_S3TC_DXT1_EXT to COMPRESSED_TEXTURE_FORMATS for GLES
The ES and desktop GL specs diverge here.  Yay!

In desktop OpenGL, the driver can perform online compression of
uncompressed texture data.  GL_NUM_COMPRESSED_TEXTURE_FORMATS and
GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats
that it could ask the driver to compress with some expectation of
quality.  The GL_ARB_texture_compression spec calls this "suitable for
general-purpose usage."  As noted above, this means
GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is not included in the list.

In OpenGL ES, the driver never performs compression.
GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give
the application a list of formats that the driver can receive from the
application.  It is the *complete* list of formats.  The
GL_EXT_texture_compression_s3tc spec says:

    "New State for OpenGL ES 2.0.25 and 3.0.2 Specifications

        The queries for NUM_COMPRESSED_TEXTURE_FORMATS and
        COMPRESSED_TEXTURE_FORMATS include COMPRESSED_RGB_S3TC_DXT1_EXT,
        COMPRESSED_RGBA_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT3_EXT,
        and COMPRESSED_RGBA_S3TC_DXT5_EXT."

Note that the addition is only to the OpenGL ES specification!

9ca4c8f6a2 i965: Ensure that all necessary state is re-emitted if we run out of aperture.
Prior to this patch, if we ran out of aperture space during
brw_try_draw_prims(), we would rewind the batch buffer pointer
(potentially throwing some state that may have been emitted by
brw_upload_state()), flush the batch, and then try again.  However, we
wouldn't reset the dirty bits to the state they had before the call to
brw_upload_state().  As a result, when we tried again, there was a
danger that we wouldn't re-emit all the necessary state.  (Note: prior
to the introduction of hardware contexts, this wasn't a problem
because flushing the batch forced all state to be re-emitted).

This patch fixes the problem by leaving the dirty bits set at the end
of brw_upload_state(); we only clear them after we have determined
that we don't need to rewind the batch buffer.

c24489b0ef i965: fold offset into coord for textureOffset(gsampler2DRect)

This just extends the existing workaround for ir_txf and

Fixes broken rendering in 'tesseract' when 'mesa_texrectoffset_bug' is

'tests/spec/glsl-1.30/execution/fs-textureOffset-Rect'.

Has been broken ~forever; suggesting including this in only 10.0 because

2b205f2864 swrast: fix delayed texel buffer allocation regression for OpenMP
Commit 9119269ca1 moved the texel
buffer allocation to _swrast_texture_span(), however, when compiled
with OpenMP support this code already runs multi-threaded so a
critical section is required to prevent multiple allocations and
rendering errors.

d46a58703a glsl: Fix inconsistent assumptions about ir_loop::counter.
The compiler back-ends (i965's fs_visitor and brw_visitor,
ir_to_mesa_visitor, and glsl_to_tgsi_visitor) assume that when
ir_loop::counter is non-null, it points to a fresh ir_variable that
should be used as the loop counter (as opposed to an ir_variable that
exists elsewhere in the instruction stream).

However, previous to this patch:

(1) loop_control_visitor did not create a new variable for
    ir_loop::counter; instead it re-used the existing ir_variable.
    This caused the loop counter to be double-incremented (once
    explicitly by the body of the loop, and once implicitly by
    ir_loop::increment).

(2) ir_clone did not clone ir_loop::counter properly, resulting in the
    cloned ir_loop pointing to the source ir_loop's counter.

(3) ir_hierarchical_visitor did not visit ir_loop::counter, resulting
    in the ir_variable being missed by reparenting.

Additionally, most optimization passes (e.g. loop unrolling) assume
that the variable mentioned by ir_loop::counter is not accessed in the
body of the loop (an assumption which (1) violates).

The combination of these factors caused a perfect storm in which the
code worked properly nearly all of the time: for loops that got
unrolled, (1) would introduce a double-increment, but loop unrolling
would fail to notice it (since it assumes that ir_loop::counter is not
accessed in the body of the loop), so it would unroll the loop the
correct number of times.  For loops that didn't get unrolled, (1)
would introduce a double-increment, but then later when the IR was
cloned for linking, (2) would prevent the loop counter from being
cloned properly, so it would look to further analysis stages like an
independent variable (and hence the double-increment would stop
occurring).  At the end of linking, (3) would prevent the loop counter
from being reparented, so it would still belong to the shader object
rather than the linked program object.  Provided that the client
program didn't delete the shader object, the memory would never get
reclaimed, and so the shader would function properly.

However, for loops that didn't get unrolled, if the client program did
delete the shader object, and the memory belonging to the loop counter
got re-used, this could cause a use-after-free bug, leading to a
crash.

This patch fixes loop_control_visitor, ir_clone, and
ir_hierarchical_visitor to treat ir_loop::counter the same way the
back-ends treat it: as a freshly allocated ir_variable that needs to
be visited and cloned independently of other ir_variables.

8eee788bd6 glsl: Teach ir_variable_refcount about ir_loop::counter variables.
If an ir_loop has a non-null "counter" field, the variable referred to
by this field is implicitly read and written by the loop.  We need to
account for this in ir_variable_refcount, otherwise there is a danger
we will try to dead-code-eliminate the loop counter variable.

Note: at the moment the dead code elimination bug doesn't occur due to
a bug in ir_hierarchical_visitor: it doesn't visit the "counter"
field, so dead code elimination doesn't treat it as a candidate for
elimination.  But the patch to follow will fix that bug, so we need to
fix ir_variable_refcount first in order to avoid breaking dead code
elimination.

9ccb6cc7b7 i965/gen6: Fix HiZ hang in WebGL Google Maps
Emitting flushes before depth and hiz resolves at the top of blorp's
state emission fixes the hang. Marchesin and I found the fix
experimentally, as opposed to adhering to a documented hardware
workaround.  A more minimal fix likely exists, but this gets the job
done.

Fixes HiZ hangs in the new WebGL Google maps on Sandybridge Chrome OS.
Tested by zooming in and out continuously for 2 hours.

b8be00e5f2 glcpp: error on multiple #else/#elif directives
The preprocessor currently accepts multiple else/elif-groups
per if-section. The GLSL-preprocessor is defined by the C++
specification, which defines the following parse-rule:

if-section:
	if-group elif-groups(opt) else-group(opt) endif-line

This clearly only allows a single else-group, that has to come
after any elif-groups.

So let's modify the code to follow the specification. Add test
to prevent regressions.

This reverts commit 136a12ac98.

According to belak51 on IRC, this commit broke Allegro, which would no
longer compile.  Applications apparently expect the GLXContextID typedef
to exist in glx.h; removing it breaks them.  A bit of searching around
the internet revealed other complaints since upgrading to Mesa 10.
