Re: [squirrelfish] sin is slow on 64 bit

What kind of optimization did you have in mind?

A 3 line assembly code which mimic the old libc: fld [src] (must be a double) fsin fst [dst] Not sure the best way of adding it to JSC. And we should also check which is correct: 32 bit fsin: sin(6.2831853071795862) = -2.4492127076447545e-16 64 bit software based fsin: sin(6.2831853071795862) = -2.4492935982947064e-16 The difference is quite big.
