[Bug tree-optimization/24609] Same value duplicated in two different registers



------- Comment #6 from ian at airs dot com  2005-11-01 18:46 -------
Created an attachment (id=10101)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10101&action=view)
.s file from gcc 3.4 -S -O2

I've attached the assembler code generated by gcc 3.4 with -S -O2.  This code
is much better than that generated by 4.1.  It does not duplicate the register,
and RTL if-conversion is able to eliminate the branch.
