Thank you for doing this extra regression testing.

Hi Dave,
On x86-64, no regression in 4.2 with the patch.
So both 4.2 and mainline patches are OK.
I'd appreciate it if you can add the testcase
- it's up to you whether to add it in a separate patch or with this patch.
Thanks for fixing it.

I have a bug I'm trying to investigate where, starting in gcc-4.2.x,

register unsigned long regvar asm ("foo");
func(arg)
{
for (...) {
