Shader runner link test
I've distilled one problem in the attached shader runner test. Seems we have
another unrolling bug somewhere in the GLSL IR unrolling pass.
We end up with the following:
FRAG
DCL OUT[0], COLOR
DCL TEMP[0..3], LOCAL
IMM[0] UINT32 {0, 4294967295, 0, 0}
IMM[1] INT32 {0, 1, 0, 0}
IMM[2] FLT32 { 1.0000, 0.0000, 0.0000, 0.0000}
0: MOV TEMP[0].x, IMM[0].xxxx
1: MOV TEMP[1].x, IMM[1].xxxx
2: BGNLOOP
3: USEQ TEMP[2].x, TEMP[1].xxxx, IMM[1].yyyy
4: UIF TEMP[2].xxxx
5: BRK
6: ENDIF
7: MOV TEMP[3], IMM[2].xxxx
8: MOV TEMP[0].x, IMM[0].yyyy
9: BRK
10: UADD TEMP[1].x, TEMP[1].xxxx, IMM[1].yyyy
11: ENDLOOP
12: MOV OUT[0], IMM[2].xxxx
13: END
