Alan Baker	2735e0851e	Remove constexpr from Analysis operators ... * Had to remove templating from InstructionBuilder as a result * now preserved analyses are specified as a constructor argument * updated tests and uses * changed static_assert to a runtime assert * this should probably get further changes in the future	2018-01-31 14:44:43 -05:00
Alan Baker	2e93e806e4	Initial implementation of if conversion ... * Handles simple cases only * Identifies phis in blocks with two predecessors and attempts to convert the phi to an select * does not perform code motion currently so the converted values must dominate the join point (e.g. can't be defined in the branches) * limited for now to two predecessors, but can be extended to handle more cases * Adding if conversion to -O and -Os	2018-01-25 09:42:00 -08:00
