2010-08-03r300/compiler: Always unroll loops when doing loop emulation.Tom Stellard
2010-08-03r300/compiler: r500 hw support for break and continue in loops.Tom Stellard
The BGNLOOP and ENDLOOP instructions are now being used correctly, which makes break and continue possible. The deadcode pass has been modified to handle breaks, and the compiler is more careful about which loops are unrolled.
2010-08-03r300/compiler: KILP may not always be inside an IF statement.Tom Stellard
2010-08-03r300/compiler: Don't unroll loops with continue or break.Tom Stellard
2010-07-14r300/compiler: fix swizzling in the transformation of Abs modifiersMarek Olšák
2010-07-13r300/compiler: implement the Abs source operand modifier for vertex shadersMarek Olšák
2010-07-13r300/compiler: emulate SIN/COS/SCS in r3xx-r4xx vertex shadersMarek Olšák
Despite the docs, the corresponding hardware instructions are r5xx-only.
2010-07-08r300/compiler: Add a register rename pass.Tom Stellard
This pass renames register in order to make it easier for the pair scheduler to group TEX instructions together. This fixes fdo bug #28606
2010-07-08r300/compiler: Fix scheduling of TEX instructions.Tom Stellard
The following instruction sequence will no longer be emitted in separate TEX blocks: 0: TEX temp[0].xyz, temp[1].xy__, 2D[0]; 1: TEX temp[1].xyz, temp[2].xy__, 2D[0]; This fixes fdo bug #25109

block.
2010-07-03r300/compiler: Correctly calculate the max number of iterations for loops.Tom Stellard
2010-07-03r300/compiler: Handle loops in deadcode analysis.Tom Stellard
This also allows us to split the loop emulation into two phases. A tranformation phase which either unrolls loops or prepares them to be emulated, and the emulation phase which unrolls remaining loops until the instruction limit is reached. The second phase is completed after the deadcode analysis in order to get a more accurate count of the number of instructions in the body of loops.
2010-06-23r300/compiler: allow 1024 instructions in r5xx vertex shadersMarek Olšák
2010-06-23r300/compiler: allow 32 temporaries in vertex shadersMarek Olšák
2010-06-23r300/compiler: emulate loops in vertex shadersMarek Olšák
It is not perfect, but it is the best we got.

2010-06-11r300/compiler: Handle more complex conditionals in loops.Tom Stellard
2010-06-11r300/compiler: Fix warning.Tom Stellard
2010-06-11r300/compiler: Handle SGT and SLE at the beginning of loops.Tom Stellard
2010-06-11r300/compiler: Verify assumptions about opcode types.Tom Stellard
2010-06-11r300/compiler: Unroll loops that decrement the counter.Tom Stellard
e.g. for(i=10; i>0; i--)
2010-06-11r300/compiler: Unroll loops that have a constant number of iterations.Tom Stellard
This only works with for loops that increment the counter. e.g. for(i=0; i<10; i++)
2010-06-11r300/compiler: Implement simple loop emulationTom Stellard
The loop emulation unrolls loops as may times as possbile while still keeping the shader program below the maximum instruction limit. At this point, there are no checks for constant conditionals. This is only enabled for fragment shaders.

This is actually better than a real implementation, which would be useless due to inaccuracy (I know because I've tried to implement it).
