| 2015-09-15 | quick fix for comparisons with constants | Quentin Carbonneaux | |
| 2015-09-15 | start work on comparisons | Quentin Carbonneaux | |
| There are two things I overlooked so far. 1. Binary instructions like cmp that do not have a result in registers need the size suffix sometimes, for example when comparing a spill location with a constant. 2. The register allocator needs to be adapted to support the comparison instruction: it is not possible to compare two spill locations without using a register. | |||
| 2015-09-15 | use correct sizes during reg allocation | Quentin Carbonneaux | |
| 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. | |||

| 2015-09-15 | clean the commutativity + fix bug in emit | Quentin Carbonneaux | |
| The commutativity information only makes sense for arithmetic expressions. To account for that, I introduced a new tri-valued boolean type B3. Memory operations, for example, will receive an undefined commutativity trit. The code emitter was buggy when rega emitted instructions like 'rax = add 1, rax', this is now fixed using the commutativity information (we rewrite it in 'rax = add rax, 1'). | |||
