Module Jasmin.SsaSource

Sourceval split_live_ranges : bool -> ('info, 'asm) Prog.func -> (unit, 'asm) Prog.func

Rename variables in the given function so that any given variable has different names in each of its liveness intervals. This may introduce fresh copy instructions tagged as “phi nodes”. The first argument to this function tells whether said renaming is applied to all variables (split_live_ranges true) or only to registers (split_live_ranges false).

Sourceval remove_phi_nodes : ('info, 'asm) Prog.func -> ('info, 'asm) Prog.func

Remove copy instructions tagged as “phi nodes”. All such instructions must be of the form “x = x”, i.e., the source and destination must be the same variable.
