Hello,
This patch gains ~1% improvements on overall CINTPEC2000 on
powerpc-linux when the number of times this optimization
is applied in each loop is restricted to one
(I can add this restriction if this patch will be accepted);
where gap gains ~5% improvements and bzip2 ~1%.
In CFPPEC2000 there was no significant improvements
except swim which gained 3% improvement but mesa,
facerec and wupwise show a regression of about 1%
each.
Revital
