Hi, all
GCC should have implemented the feature of moving
floating point through integer registers according to
the comments listed in
http://gcc.gnu.org/projects/optimize.html#fpmove.
I'm going to test its benefit on IA64 platform for
floating point benchmarks. But I wonder whether this
feature has been implemented on IA64. If not, can
anyone give some advice about how to implement it?
