PPC gives:
_foo:
lwz r2,4(r3)
b L2
L7:
mr r2,r0
L2:
lwz r0,0(r4)
addi r4,r4,4
add r0,r2,r0
cmpw cr7,r0,r5
blt+ cr7,L7
stw r2,0(r3)
blr
in the following code gcc choses the registers in such a way that it causes
itself an extra copy for every loop iteration and has to jump past the copy to
start the loop... it's probably easiest to describe just by looking at the
code:
% cat jmp-over.c
void foo(int *v, int *d, int g)
{
int s = v

This patch works great for me.
Tested on i386-freebsd6 and i386-linux-2.6.15-gentoo by calling CNI in threads
created by an absolute non-CNI aware c++ Corba library.
