Sorry, correct a description, GCC 4.3.4's configuration is wrong.
GCC 4.3.4 Configured with: ../configure --prefix=/usr --infodir=/usr/share/info
--mandir=/usr/share/man --libdir=/usr/lib64

1. Can you provide the preprocessed source
Sorry,I trace the linux source code, the kernel used __builtin___memcpy() to

Have you actually measured any slowdown, or you just think that rep movsd
must be 8 times faster than rep movsb?
Yes, actually I first measured

Anyway, please see http://gcc.gnu.org/bugs.html, without preprocessed source
and gcc options passed to it this report is useless.
Also, if it is a memcpy into a hardware device area,
