Thanks for reminder, I've started bootstap and test on ia64 and x86-64.

Thanks! I notified downstream, hopefully they will give it testing through a
bump to gcc-4.

This bug prevents Erlang 14B2 from building on my machine, so for me it is
serious. Someone else has to tell whether there will be further 4.4 releases,
of course.

P.S: Maybe you can backport it anyway, since I opened Gentoo bug #365045 [1].
Having the backport readily available from upstream would probably help
including it in a distr

The patch from 4.5 can likely be ported to 4.4 somewhat easy, however, it is
big enough and I am not sure that there will be any more releases off
4.4-branch. If there is such a

Will 4.4 also be fixed? A release candidate for 4.4.6 was just released, so it
should probably happen quickly.

Andrey,
I was just looking at PR 48191, a bug submitted against GCC 4.5.2. It looks
like it is caused by the same problem that this patch fixes. Can you back port
this fix to the 4.5

The below patch implements keeping dominance info up to date in the scheduler.
After discussions with Alexander, I think that it will be better to leave the

The problem is in the remove_insns_that_need_bookkeeping function, which should

This is failing due to invalid rtl unsharing. The asm has two dests. We end
up with a parallel with two sets, and the ASM_OPERAND_INPUT_VEC in each SET_SRC
is supposed to be the same rtl pointer. This is checked by
