| 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_sparc: Add code rewrite RA callbacks | Magnus Lång | |
| These will not only be useful for hipe_regalloc_prepass, but also, after the introduction of a mk_move/2 (or similar) callback, for the purpose of range splitting. Since the substitution needed to case over all the instructions, a new module, hipe_sparc_subst, was introduced to the sparc backend. | |||
