A first release candidate for GCC 4.4.1 is available from
ftp://gcc.gnu.org/pub/gcc/snapshots/4.4.1-RC-20090715

GCC 4.4.1 Release Candidate 1 has been released, the branch is now

The trunk is in Stage 1. We expect that Stage 1 will last through
at least July and August.
There are still large pending merges we are aware of, specifically
the VTA, LTO and Graphite branches will be considered when deciding
when to go to Stage 3.

Ah ok, so I can see why it would not be able to perform that
optimization around the loop but I changed the code to simply have
this:
uint64_t foo (void)
{
return data[0] + data[1] + data[2];
}
And this generates :
la r9,data
la r7,data+8
ldd r6,0(r7)
ldd r8,0(r9)
ldd
I agree. I've actually pretty much finished that change and it seems
to be stable. I think it will be more maintainable in the
constraints.md state than it was before,
Thanks again,

I would also recommend to try a newer snapshot from the gcc 4.4 release branch.

Is it the nesting of loops or really the number of function calls that is
important?

Confirmed. With -O2 -fno-inline we get in .optimized
func_36 ()
{
bb 2:
g_10 = 1;
func_53 ();
g_64 = 1;
return 1;
FRE does this. I'll check.

We have wrong SSA form before FRE:
;; Function func_36 (func_36)
func_36 ()
{
uint8_t g_64.8;
int64_t g_10.5;
bb 2:
# .MEM_17 = VDEF .MEM_16(D)
g_10 = 1;
# VUSE .MEM_17
g_10.5_2 = g_10;
if (g_10.5_2
