(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). 895838 1 203428 jbriance 2013-05-31 02:51:30 -0700 Created attachment 203428 Fix floating point comparisons in sh4 baseline JIT 895947 2 203428 commit-queue 2013-05-31 11:21:58 -0700 Comment on attachment 203428 Fix floating point comparisons in sh4 baseline JIT Clearing flags on attachment: 203428 Committed r151032: <http://trac.webkit.org/changeset/151032> 895948 3 commit-queue 2013-05-31 11:22:01 -0700 All reviewed patches have been landed.
