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. |
