2016-09-05hipe: Refactor ra callbacks to accept context argMagnus Lång
This allows us to pass around the context data that hipe_regalloc_prepass needs cleanly, without using process dictionary or parameterised modules (like it was previous to this change).
2016-09-05hipe: Reuse liveness between regalloc iterationsMagnus Lång
This is sound because the liveness data structure only stores liveness info at basic block boundaries, and the rewrites that happen in TargetSpecific:check_and_rewrite/2 preserves all existing definitions and uses, and all new liveness intervals, belonging to newly introduced temporaries, are always local to a basic block, and thus do not show up in the liveout or livein sets for the basic block.
2016-08-30hipe_ppc: Minimise CFG<->linear conversionsMagnus Lång
Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_ppc_main.
2016-08-30hipe: Reuse liveness info for spillminMagnus Lång
For x86, additionally reuse liveness from float LSRA for the GP LSRA.
