[Openmcl-devel] Allegro 8.0 is in the same situation [Re: how does one cause stack-allocation for floats? [2]

[James Anderson]

hello again;


ok, here are allegro 8.0 figures for the same functions.
it's an opteron-850, so it's hard to compare, and there are some numbers,
like the single-float behaviour, which don't make sense.


----------------------|    single-float     | single/stack  | double-float        | double/stack   | double no-dcl       |
allegro 6.2 / P4-2.8G | 4484 . 3436 . 320MB | 406 . 0 . 496 | 6562 . 4638 . 480MB | 406 .  0 .  24 | -                   |
allegro 6.2 / AMD-850 |  172 .    0 .    16 | 156 . 0 .  16 | 1250 .    0 .  24   |  92 .  0 .  24 | 5172 . 3656 . 480MB |
allegro 8.0 / AMD-850 | 1015 .  502 . 320MB | 110 . 0 .  72 | 1203 .    0 .  80   | 125 .  0 .  80 | 2218 .  828 . 480MB |

in any case, to these eyes, the bottom line is still that there are some things the compiler just needs to be told.
