Hi, My stougle with USE_JSVALUE32_64 still continues on ARM. In emit_op_jfalse, there is a comparison here (fpRegT0 contains 0.0): addJump(branchDouble(DoubleEqual, fpRegT0, fpRegT1), target + 2);
In x86, if either operand is NaN, the zero flag is set by definition (ucomisd instruction). I have no idea why (NaN == anything is true?). Unfortunately, ARM does not set the zero flag. What would be a portable way to improve this instruction? (and emit_op_jtrue) Perhaps this affects the possible thumb2 implementation with USE_JSVALUE32_64 as well.
