  I noticed that memcpy() was called by a simple pattern even when
 providing options: -Os -march=i386 -minline-all-stringops

-Os disables inlining of memcpy, on the assumption that this will always result in smaller code.

If you want someone to look at this problem, I suggest you file a bug report into our bugzilla database. Messages tto the gcc list aren't tracked, so it is unlikely anyone will take a look unless it goes into our bug database. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
