question about llvm partial unrolling/runtime unrolling
Hi Hal,
I did
opt.exe -S -debug -loop-unroll -unroll-runtime=true -unroll-count=4
csShader.ll
and it prints out:
Args: opt.exe -S -debug -loop-unroll -unroll-runtime=true -unroll-count=4
csShader.ll
Loop Unroll: F[build_cs_5_0] Loop %loop_entry
Loop Size = 82
partially unrolling with count: 1
Thanks,
Frances
