When building for an ARM system ABI that uses the hard-float standard, passing the floating point operands in registers, the asm.js code is mis-compiled and errors shows up in the asm.js jit-tests.
Just need to skip loading d0 from r0 and r1 when passing the result in d0.

Comment on attachment 736766 [details] [diff] [review] Fix the return of a floating point value from an ARM asm.js entry. Review of attachment 736766 [details] [diff] [review]: ----------------------------------------------------------------- I would be very surprised if this were the only bug in the hardfp implementation, but that isn't a good reason to not land this.
