Atm we generate this dead code inbetween forked and joining:
|
||
|
|
|
||
|
|
mov.u32 %r28, %ntid.y;
|
||
|
|
mov.u32 %r29, %tid.y;
|
||
|
|
add.u32 %r30, %r29, %r29;
|
||
|
|
setp.gt.s32 %r31, %r30, 19;
|
||
|
|
@%r31 bra $L2;
|
||
|
|
add.u32 %r25, %r28, %r28;
|
||
|
|
mov.u32 %r24, %r30;
|
||
|
|
$L3:
|
||
|
|
add.u32 %r24, %r24, %r25;
|
||
|
|
setp.le.s32 %r33, %r24, 19;
|
||
|
|
@%r33 bra $L3;
|
||
|
|
$L2:
|
||
|
|
|
||
|
|
so the loop is not recognized as empty loop (which we detect by seeing if
|
||
|
|
joining immediately follows forked). */
