| 2015-09-15 | fix my sloppy understanding of x86 assembly! | Quentin Carbonneaux | |

| 2015-09-15 | movsb is not movsbl without suffix... | Quentin Carbonneaux | |
| 2015-09-15 | attempt factoring store emission code | Quentin Carbonneaux | |
| 2015-09-15 | ugly support for store/load | Quentin Carbonneaux | |
| 2015-09-15 | simplify parsing | Quentin Carbonneaux | |
| 2015-09-15 | add nmem to opdesc for use in the spiller | Quentin Carbonneaux | |
| This new machine-independent mechanism might not be general enough in the long term but, now, it provides a flexible way to inform the spiller about the maximum number of arguments of an instruction that can be spill locations. | |||
| 2015-09-15 | add some load/store operations | Quentin Carbonneaux | |

| 2015-09-15 | split cmp in two sizes | Quentin Carbonneaux | |
| 2015-09-15 | fix two bugs in isel | Quentin Carbonneaux | |
| 2015-09-15 | fix 2 bad bugs in rega and improve substraction | Quentin Carbonneaux | |
| The substraction contrained the register allocator to allocate a different register for the result and the second operand, now, we use a neg trick to compile it down. The machinery that was setup is, regardless, interesting and will have to be used for floating point computations (division). The first bug in rega made broke the explicited loop invariant: we were using register allocation unavailable information from other blocks. It's still unclear how we got wrong results from that considering mappings are all 0-initialized. The second bug is a stupid one, one sizeof operator was missing from a memcpy... | |||
| 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 cmp $0, it works with spill slots | Quentin Carbonneaux | |
| 2015-09-15 | adapt emit to new Ref setting | Quentin Carbonneaux | |
| 2015-09-15 | start work on word/long handling | Quentin Carbonneaux | |
| 2015-09-15 | replace IA with X for x64 instructions | Quentin Carbonneaux | |
| 2015-09-15 | avoid keyword clash by using cons for constants | Quentin Carbonneaux | |
| 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'). | |||
