malv | so I am trying to benchmark my matrix multiply function. When I turn on -O3 the time it takes for a billion 3x3 matrix multiplies is 0 | 16:05 |
---|---|---|
malv | why is this? | 16:05 |
maddernick | compiler optimized something away? | 16:06 |
malv | but what might do that | 16:07 |
maddernick | look at the ASM output | 16:08 |
malv | figured it out | 16:11 |
malv | only seems to compute the matrix if I print it out at the end | 16:11 |
maddernick | its clever like that ;) | 16:13 |
