4cf2be408e r600g: Use LOOP_START_DX10 for loops
LOOP_START_DX10 ignores the LOOP_CONFIG* registers, so it is not limited
to 4096 iterations like the other LOOP_* instructions.  Compute shaders
need to use this instruction, and since we aren't optimizing loops with
the LOOP_CONFIG* registers for pixel and vertex shaders, it seems like
we should just use it for everything.

6b3355c91d glsl: Don't add structure fields to the symbol table
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.

8a3a76e1da i965: Validate requested GLES context version in brwCreateContext
For GLES1 and GLES2, brwCreateContext neglected to validate the requested
context version received from the DRI layer. If DRI requested an OpenGL
ES2 context with version 3.9, we provided it one.

Before this fix, the switch statement that validated the requested GL
context flavor was an ugly #ifdef copy-paste mess. Instead of reproducing
the copy-past-mess for GLES1 and GLES2, I first refactored it.  Now the
switch statement is readable.

b683891fda mesa: Fix segfault on reading from a missing color read buffer.
The diff looks funny, but it's moving the integer vs non-integer check
below the _mesa_source_buffer_exists() check that ensures
_ColorReadBuffer is non-null, so we get a GL_INVALID_OPERATION instead
of a segfault.  This looks like it had regressed in the
_mesa_error_check_format_and_type() changes, which removed the first of
the two duplicated checks for the source buffer.  Fixes segfault in the
new piglit ARB_framebuffer_object/negative-readpixels-no-rb.

a3f5601465 glcpp: Reject garbage after #else and #endif tokens
Previously we were accepting garbage after #else and #endif tokens when
the previous preprocessor conditional evaluated to false (eg, #if 0).

When the preprocessor hits a false conditional, it switches the lexer
into the SKIP state, in which it ignores non-control tokens. The parser
pops the SKIP state off the stack when it reaches the associated #elif,
#else, or #endif. Unfortunately, that meant that it only left the SKIP
state after the lexing the entire line containing the #token and thus
would accept garbage after the #token.

To fix this we use a mid-rule, which is executed immediately after the
#token is parsed.

05974cb8c6 i965/vs: Preserve the type when copy propagating into an instruction.
Consider the following code, which reinterprets a register as a
different type:

mov(8)          g6<1>F          g1.4<0,4,1>.xF
and(8)          g5<1>.xUD       g6<4,4,1>.xUD   0x7fffffffUD

Copy propagation would notice that we can replace the use of g6 with
g1.4 and eliminate the MOV.  Unfortunately, it failed to preserve the UD
type, incorrectly generating:

and(8)          g5<1>.xUD       g6<4,4,1>.xF    0x7fffffffUD

97eed6da97 i965/vs: Don't lose the MRF writemask when doing compute-to-MRF.
Consider the following code sequence:

   mul(8)          g4<1>F          g1<0,4,1>.wzwwF g3<4,4,1>.wzwwF
   mov.sat(8)      m1<1>.xyF       g4<4,4,1>F
   mul(8)          g4<1>F          g1<0,4,1>.xxyxF g3<4,4,1>.xxyxF
   mov.sat(8)      m1<1>.zwF       g4<4,4,1>F

The compute-to-MRF pass will discover the first mov.sat and attempt to
replace it by rewriting earlier instructions.  Everything works out,
so it replaces scan_inst's destination file, reg, and reg_offset,
resulting in:

   mul(8)          m1<1>F          g1<0,4,1>.wzwwF g3<4,4,1>.wzwwF
   mul(8)          g4<1>F          g1<0,4,1>.xxyxF g3<4,4,1>.xxyxF
   mov.sat(8)      m1<1>.zwF       g4<4,4,1>F

Unfortunately, it loses the .xy writemask on the mov.sat's MRF
destination.  While this doesn't pose an immediate problem, it then
proceeds to transform the second mov.sat, resulting in:

   mul(8)          m1<1>F          g1<0,4,1>.wzwwF g3<4,4,1>.wzwwF
   mul(8)          m1<1>F          g1<0,4,1>.xxyxF g3<4,4,1>.xxyxF

Instead of writing both halves of the vector (like the original code),
it overwrites the full vector both times, clobbering the desired .xy
values.

When encountering a MOV, the compute-to-MRF code scans for instructions
which generate channels of the MOV source.  It ensures that all
necessary channels are available (possibly written by several
instructions).  In this case, *more* channels are available than
necessary, so we want to take the subset that's actually used.
Taking the bitwise and of both writemasks should accomplish that.

This was discovered by analyzing an ARB_vertex_program test
(glean/vertProg1/MUL test (with swizzle and masking)) with my new
Mesa IR -> Vec4 IR translator code.  However, it should be possible
with GLSL programs as well.

a908f4a754 glcpp: Don't use infinite lookhead for #define differentiation.
Previously, we used lookahead patterns to differentiate:

   #define FOO(x)  function macro
   #define FOO (x) object macro

Unfortunately, our rule for function macros:

   {HASH}define{HSPACE}+/{IDENTIFIER}"("

relies on infinite lookahead, and apparently triggers a Flex bug where
the generated code overflows a state buffer (see YY_STATE_BUF_SIZE).

There's no need to use infinite lookahead.  We can simply change state,
match the identifier, and use a single character lookahead for the '('.
This apparently makes Flex not generate the giant state array, which
avoids the buffer overflow, and should be more efficient anyway.

Fixes piglit test 17000-consecutive-chars-identifier.frag.

NOTE: This is a candidate for every release branch ever.

fb8d6b41d8 st/mesa: replace REALLOC() with realloc()
We should use the later since we're freeing the memory with free(),
not the gallium FREE() macro.

This fixes a mismatch when using the gallium debug memory functions.

NOTE: This is a candidate for the 9.0 branch.

b63f8f7906 mesa: Don't flatten IF statements by default.
MaxIfDepth of 0 means "flatten all the time", not "never flatten".
This is only desirable on hardware that can't support control flow;
software rasterization and most hardware drivers want this.

This alters behavior for swrast as well as i915.  Tested on i915.

NOTE: This is a candidate for stable release branches.
