2015-09-15 | major lifting: get rid of RReg | Quentin Carbonneaux | |
I've been septic since I introduced it, this commit proves that it costs more than it helps. I've also fixed a bad bug in rega() where I alloc'ed the wrong size for internal arrays. Enums now have names so I can use them to cast in gdb to get the name corresponding to a constant. | |||
2015-09-15 | use a new Ref type for registers | Quentin Carbonneaux | |
This might not be a good idea, the problem was that many spurious registers would be added to the Bits data-structures during compilation (and would always remain 0). However, doing the above modification de-uniformizes the handling of temps and regs, this makes the code longer and not really nicer. Also, additional Bits structures are required to track the registers independently. Overall this might be a bad idea to revert. | |||
