--- Comment #6 from Ilia Mirkin <[email protected]> --- Fail. Their compiler is a lot smarter than ours. (Note that I'm pretty sure their code starts at 0x100, which is why the branch destinations are all off.) 00000000: 10008005 03f80003 mov b32 $r1 0x3f800000 00000008: 8000000c interp $r3 v[0x0] 0000000c: 1000fe10 mov b32 $r4 $r63 00000010: 10008208 mov b32 $r2 $r1 00000014: 10008200 mov b32 $r0 $r1 00000018: 90000615 00000780 rcp f32 $r5 $r3 00000020: b08009fd 604107c8 set $c0 # g f32 $r4 c1[0x0] 00000028: 10039003 00000680 (lgu $c0) bra 0x1c8 00000030: b000080d 04204003 add f32 $r3 $r4 0x42040000 00000038: 82010a18 interp $r6 v[0x4] $r5 0000003c: 82020a1c interp $r7 v[0x8] $r5 00000040: c0060621 00000780 mul rn f32 $r8 $r3 $r6 00000048: c02e0e0d 0486563f mul f32 $r3 $r7 0x486563ee 00000050: b00d0819 03f8cccf add f32 $r6 $r4 0x3f8ccccd 00000058: e000100d 04367003 add f32 $r3 (mul $r8 0x43670000) $r3 00000060: c0030c0d 00000780 mul rn f32 $r3 $r6 $r3 00000068: b000060d c0000780 presin f32 $r3 $r3 00000070: 9000060d a0000780 cos f32 $r3 $r3 00000078: b08107fd 60c107c8 set $c0 # g f32 $r3 c3[0x4] 00000080: c0830809 00c00680 (lgu $c0) mul rn f32 $r2 $r4 c3[0xc] 00000088: 10007e05 0403c680 (lgu $c0) mov b32 $r1 $r63 00000090: 10007e01 0403c680 (lgu $c0) mov b32 $r0 $r63 00000098: 10039003 00000680 (lgu $c0) bra 0x1c8 000000a0: b0000811 03f80003 add f32 $r4 $r4 0x3f800000 000000a8: b082080d 60c04780 set $r3 l f32 $r4 c3[0x8] 000000b0: a000060d 04114780 cvt abs u32 $r3 s32 $r3 000000b8: 303f07fd 640087c8 set $c0 # e u32 $r3 $r63 000000c0: 10024003 00000700 (geu $c0) bra 0x120 000000c8: b00d0001 03dccccf add f32 $r0 $r0 0x3dcccccd 000000d0: 1000080d 24c0c781 exit ld $r3 b32 c3[0x10] So... I guess the next move is to write a horrendously twisted glsl program that even their compiler can't avoid breaks on, and see what happens. -- You are receiving this mail because: You are the assignee for the bug.
