does it work everywhere or not
Hi asm guys, 040+ experts are wanted here.
That's just a few corner cases which i don't know for sure how they behave. Upto 68030 i know, but for 68040/68060 i can't check. IIRC move16 (a0)+,(a0)+ will copy the data onto itself then increment a0 twice and i'm wondering if other stuff wouldn't behave the same... Code:
move.l (a0)+,(a0)+ ; copies data on next long or onto itself ? |
Quote:
1. long data are copied, A0 is +8. 2. long data are copied, A0 is -8. 3. long data from 8(a7) are copied, A7 is -4. 4. long data from (a7)+ are copied, A7 is + 4. 5. A7 is pushed on stack. 6. same like pea (a7). 7. pushes a7+4. |
