Fix translateX86CC: if SetCCOpcode is SETULE and LHS is a foldable load, then LHS and RHS are swapped and SetCCOpcode is changed to SETUGT. But the later code is expecting operands to be the wrong way round for SETUGT, but they are not in this case, resulting in an inverted compare. The solution is to move the load normalization before the correction for SETUGT. This bug was tickled by LegalizeTypes which happened to legalize the testcase slightly differently to LegalizeDAG. llvm-svn: 58092 2008-10-24 15:03:10 +02:00
