Identifier of patterns to be transformed by phi_opt.

Enumerator
UNKNOWN	Unknown pattern.
DIFF_NOTHING	Empty basic block with multiple input.
GIMPLE_NOTHING	Empty basic block dominated by assign can be removed without further changes.
IF_MERGE	Edges coming from if to be merged.
IF_NOTHING	Basic block dominated by if can be removed without further changes.
IF_REMOVE	Phi dominated by gimple_cond to be removed.
MULTI_MERGE	Phi dominated by gimple_multi_way_if to be merged.
MULTI_NOTHING	Basic block dominated by multi way if can be removed without further changes.
MULTI_REMOVE	Phi dominated by gimple_multi_way_if to be removed.
UNCHANGED	Transformation blocked by timing.
