I erroneously added this back in January 2011 in commit 88421589.
Looking at the commit message, I have no idea why I added it. It only
added non-array structure fields to the symbol table, so array structure
fields are treated correctly.
Fixes piglit tests structure-and-field-have-same-name.vert and
structure-and-field-have-same-name-nested.vert. It should also fix
WebGL conformance tests shader-with-non-reserved-words.
NOTE: This is a candidate for the stable release branches.

R6xx doesn't work - the issue seems to be with flushing (sometimes
the destination buffer contains garbage). There are no hangs, so we're good.
R7xx doesn't seem to have any alignment restriction despite our initial
thinking. Everything just works.

This patch enhances the varying packing code so that flat varyings of
uint, int, and float types can be packed together.
We accomplish this in lower_packed_varyings.cpp by making the type of
all flat varyings ivec4, and then using information-preserving type
conversions (e.g. ir_unop_bitcast_f2i) to convert all other types to
ints.
The varying_matches::compute_packing_class() function is updated to
reflect the fact that varying packing no longer needs to segregate
varyings of different base types.
Fixes piglit test varying-packing-mixed-types.

v2: Split lower_packed_varyings_visitor::bitwise_assign into
pack/unpack variants.
The GLSL 1.30 spec only allows vertex shader outputs and fragment
shader inputs ("varyings" in pre-GLSL-1.30 parlance) to be of type
int, uint, float, or vectors, matrices, or arrays thereof. Bools,
bvec's, and structs are prohibited. (Integral varyings were
prohibited prior to GLSL 1.30).
Previously, Mesa only performed this check on variables declared with
the "varying" keyword, and it always performed the check according to
the pre-GLSL-1.30 rules. As a result, bools and structs were allowed
to slip through, provided they were declared using the new in/out
syntax.
This patch modifies the error check so that it occurs after "varying"
is converted to "in/out", and corrects it to properly account for GLSL
version.
Fixes piglit tests:
in-bool-prohibited.frag
in-bvec2-prohibited.frag
in-bvec3-prohibited.frag
in-bvec4-prohibited.frag

This patch adds logic to allow the ast_to_hir function
apply_type_qualifier_to_variable() to tell whether it is acting on a
variable declaration or a function parameter. This will allow it to
correctly interpret the meaning of "out" and "in" keywords (which have
different meanings in those two contexts).

linker.cpp is getting pretty big, and we're about to add even more

varyings to its own file.

When analyzing a loop where the loop condition is expressed in the
non-standard order (e.g. "4 > i" instead of "i < 4"), we were
reversing the condition incorrectly, leading to a loop bound that was
off by 1.

This is not as optimized as r600g - the MSAA compression is missing,
so r300g needs a lot of bandwidth (more than r600g to do the same thing).
However, if the bandwidth is not an issue for you, you can enjoy this
unoptimized MSAA support.
The only other missing optimization for MSAA is the fast color clear.
MSAA is enabled on r500 only, because that's the only GPU family I tested.
That said, MSAA should work on r300 and r400 as well (but you must set
RADEON_MSAA=1 to allow it, then turn MSAA on in your app or set GALLIUM_MSAA=n,
n >= 2, n <= 6)
I will enable the support by default on r300-r400 once someone (other than me)
tests those chipsets with piglit.
The supported modes are 2x, 4x, 6x.
The supported MSAA formats are RGBA8, BGRA8, and RGBA16F (r500 only).
Those 3 formats are used for all GL internal formats.
Tested with piglit. (I have ported all MSAA tests to GL2.1)

The OpenGL 3.2 core profile spec says:
"The following base internal formats from table 3.11 are
color-renderable: RED, RG, RGB, and RGBA. The sized internal formats
from table 3.12 that have a color-renderable base internal format
are also color-renderable. No other formats, including compressed
internal formats, are color-renderable."
The OpenGL 3.2 compatibility profile spec says (only ALPHA is added):
"The following base internal formats from table 3.16 are
color-renderable: ALPHA, RED, RG, RGB, and RGBA. The sized internal formats
from table 3.17 that have a color-renderable base internal format
are also color-renderable. No other formats, including compressed
internal formats, are color-renderable."
Table 3.12 in the core profile spec and table 3.17 in the compatibility
profile spec list SNORM formats as having a base internal format of RED,
RG, RGB, or RGBA. From this we infer that they should also be color
renderable.
The OpenGL ES 3.0 spec says:
"An internal format is color-renderable if it is one of the formats
from table 3.12 noted as color-renderable or if it is unsized format
RGBA or RGB. No other formats, including compressed internal
formats, are color-renderable."
In the OpenGL ES 3.0 spec, none of the SNORM formats have "color-
renderable" marked in table 3.12. The RGB I and UI formats also are not
color-renderable in ES3, but we'll save that change for another patch.
Both NVIDIA's closed-source driver (version 304.64) and AMD's
closed-source driver (Catalyst 12.6 on HD 3650) reject *all* SNORM
formats for renderbuffers in OpenGL 3.3 compatibility profiles.
