| 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 | fail on constant comparisons | Quentin Carbonneaux | |
| In the future they will be eliminated by constant propagation. | |||
| 2015-09-15 | support for large constants | Quentin Carbonneaux | |
| It was not as simple as I thought. All constants used in 32b context get truncated to 32 bits. All constants in 64b contexts can either remain as immutables are have to be evicted in a register, this choice is taken in noimm(). The case of the comparison needs to be documented since the context is not clearly 32 or 64 bits. I am still unsure if this is fully correct. | |||

| 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 regs of the correct type in isel | 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. | |||
