Summary [sh4] Fix floating point comparisons in baseline JIT
Julien Brianceau
Reported 2013-05-31 02:32:01 PDT
Current implementation of branchDouble function in baseline JIT is wrong for some conditions (1) and overkill for others (2). (1) With DoubleGreaterThanOrEqual condition for instance, branch will be taken if either operand is NaN with current implementation whereras it should not. (2) With DoubleNotEqualOrUnordered condition for instance, performed NaN checks are useless (because comparison result is false if either operand is NaN).
