Re: [PATCH] RFA C4X just unconditionally sets -ffast-math (nearly)



Wiadomość napisana w dniu 2006-12-29, o godz03:07, przez Andrew Pinski:


1. C4x has its own float format so it might actually be valid to do these transformations.

-ffast-math actually implies behavior change pretty much regardless of the
floating point unit in use, because it is "screwing" with quite a lot algebraic
transformations, which don't depend on the usual (and unusual for that matter)
peculiarities of FP representations.
