0fbc4c51a0 Rework _mesa_update_texture_compare_function() to only be called during 
state validation/update.

Note that we're still temporarily skipping the test for an active fragment
program.  Need to fix shadow2D() ...

0186f1bc83 Temporarily disable the calls to _mesa_update_texture_compare_function(). 
This fixes the depth-peel regression reported by Brad King.

84d1b24647 Fix ARB_fp spec conformance bug WRT shadow sampling. 
The ARB_fp (and other assembly-level fragment program specs) say that the
depth comparison function is always GL_NONE in fragment program mode.

8b5fce6bcc Put gl_program_machine into swrast structure rather than using a local variable. 
Basically an easy way to make sure the memory gets initialized once (to zero)
to avoid lots of valgrind warnings.

17ad1d12eb Check if FRAG_RESULT_COLR is written and update span->interpMask, arrayMask. 
Also, fix an assertion.

1c09bcfdda Implement support for GL_ARB_draw_buffers with GL_MAX_DRAW_BUFFERS > 1. 
GL_MAX_DRAW_BUFFERS is currently 4.
Added gl_FragData[] output for fragment programs.
In _swrast_write_rgba_span() loop over the color outputs/renderbuffers.

10b5895597 Implement gl_FrontFacing for fragment shaders. 
For the time being, we put the gl_FrontFacing value in the FOGC.Y input
register.  Combining FOGC and FrontFacing in one register is a bit of a
hack and may need to be changed someday.

f6803de739 Use the new unified vertex/fragment program interpreter from prog_execute.c. 
Currently, DDX, DDY don't work.

501ee87180 Lots of changes to prog_print.c code. 
Mainly, allow printing programs in either ARB, NV or "debug" formats.

4aa487e796 Use IR_LOOP to represent do-while and for-loops. 
Also, start moving high vs. low-level instruction selection into slang_emit.c

f22ed0986a Implement CONT, improve BRK. 
IR_LOOP's BranchNode ptr is the head of a linked list of CONT and BRK nodes.
After emitting loop, walk over the linked list, filling in the CONT/BRK
instruction's BranchTarget field (location of the ENDLOOP instruction, or
one past).

2755c798f3 BRK instruction's BranchTarget field now used for efficiently breaking out of loops. 
BRK's BranchTarget field actually points to the top of the loop, not the
bottom, since we don't know the later's location yet.  In the interpreter,
basically do an indirect jump to update the PC.

8608079647 Use IR node's BranchNode field for IF/ELSE/ENDIF instructions. 
This allows us to back-patch the IF/ELSE instruction's BranchTarget field
to point to the location of the ELSE/ENDIF instructions.  No longer have to
search for ELSE/ENDIF in the interpreter.  Also makes it trivial to translate
IF/ELSE instructions into conditional/unconditional BRA instructions.

cf92c72797 Initial implementation of high-level flow-control instructions. 
IF/ELSE/ENDIF and BEGIN_LOOP/END_LOOP/BREAK instructions seem to work.
Disabled by default though until better tested.
Implemented IR_NOT, but needs optimization.

01001d80e2 Initial support of loop and subroutine instructions. 
New high-level flow-control instructions, both at IR level and GPU instructions
for looping and subroutines.

f3e507ef9f New SWspanarrays attribs[] array. 
Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed
by FRAG_ATTRIB_* values.
Eliminates need to copy data into fragment program machine input registers.
Will lead to future clean-ups.
