2017-03-16 | hipe: Add pseudo_spill_f?move instructions | Magnus Lång | |
These pseudo instructions are added to all backends and allow spill slot to spill slot move coalescing in a clean way. They have regular move semantics, but contain an additional scratch register to be used if both source and destination are spilled, and can not be move coalesced. Additionally, a register allocator callback Target:is_spill_move(Instr, Context) is added which allows the spill slot allocators to check for these instructions and try to coalesce the spill slots the two temporaries are allocated to. | |||

2016-09-02 | hipe: Add hipe_regalloc_prepass | Magnus Lång | |
hipe_regalloc_prepass speeds up register allocation by spilling any temp that is live over a call (which clobbers all register). In order to detect these, a new function was added to the target interface; defines_all_alloc/1, that takes an instruction and returns a boolean. | |||
