Estimated hours taken: 4 compiler/frameopt: Bug fix: make sure that the transformation that keeps stack frames put the instruction that restores succip before a livevals/goto pair. It used to put it in between the livevals and the goto, which violates an invariant that value numbering depends on. compiler/vn_table: Allow the two operands of an operator to be the same. compiler/vn_util: Add simplification rules for dealing with boolean and and or, and rules exploiting the identities of several operators. tests/hard_coded/float_map: A test case for the fix to builtin_float_compare recently checked in by Fergus. tests/hard_coded/Mmake: Enable the new test case. tests/valid/livevals_seq: A new test case for the fix to frameopt. tests/valid/double_vn: A new test case for the fix to vn_table. tests/valid/Mmake: Enable the new test cases.
