------- Comment #4 from pinskia at gcc dot gnu dot org 2007-06-10 03:23 ------- This is an extension that GCC allows some constant folding with some functions.
So this is just a missed optimization of not constant folding sin. And yes this is fixed in 4.3.0 by the use of MPFR. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Component|c |middle-end Keywords| |missed-optimization Resolution| |FIXED Summary|a constant value is said to |not constant folding sin |be not constant | Target Milestone|--- |4.3.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32099
