The following code is a testcase for avr where reload generates wrong
code:
struct S
{
unsigned char a, b;
} ab = {12, 34};
void yoo (struct S y)
{
__asm volatile ("ldi %B0, 56" : "+y" (y));
y.a = 0;
__asm volatile ("; y = %0" : "+y" (y));
ab = y;
}
The asm just serves to dir

Not clear at all, a regular LTO bootstrap had failed on cc1 for days here.

GNU ld (with plugins) for me, but --enable-checking=yes,rtl. Maybe H.J. had
e.g. --enable-checking=release. In any case, something is brittle ATM.

This merge brings the branch up to rev 172662.
There are some LTO failures which are ICEs induced by a new
assertion I added in bp_pack_value. We discussed this in
http://gcc.gnu.org/ml/gcc-patches/2011-04/msg01115.html.
The failure happens when we try to pack DECL_OFFSET_ALIGN. We
only try to

I found the backend of gcc to be somewhat difficult to fathom, and so I decided
to convert small-c.
But aside from this bringing linux to the masses, you deserve to be informed.
