I'm testing this patch on x86_64-linux, but it won't make any difference
there.
So can you guys test on arm/alpha please and

Hardly to believe, but alpha finished --with-build-config=bootstrap-lto build,
with lto crippled by the following patch:

It's tedious to look at this without a testcase that triggers on native
x86_64. My usual simple crosses do not work with LTO as I

I get a similar issue on powerpc with -O3 used on the object file and then -O0
used for the final link. Though the simple example does not show the issue on
PPC.

I have hit what looks as the same problem on alpha for gcc.dg/lto/20090116_0.c:
int foo(void) {
int ret, i;
for (i = 0; i 1; i++)
ret = 0;
for (i = 0; i 1; i++)
ret = 1;
return ret;
}

Confirmed on alpha with attached testcase:
~/gcc-build/gcc/xgcc -B ~/gcc-build/gcc/ -O1 -fwhopr -fPIC -c pr41159.i
~/gcc-build/gcc/xgcc -B ~/gcc-build/gcc/ c_lto_20090116_0
.o -O1 -fwhopr -fPIC -shared -O0 pr41159.o

Needs re-confirming, I think this has been fixed.
