This patch fixes the IA64 bootstrap when building libunwind. When using
-fexceptions libunwind will have a reference to __gcc_personality_v0 and
the bootstrap fails, using -fno-exceptions fixes this. This problem
I've committed this patch to fix part of PR 51113. there are (at least) 3 issues
going on.
*) I'd forgotten to propagate symbol visibility from the fn-decl to the
externally visible gcov objects. I don't know if the PR actually exposed that
problem, but this patch fixes it.
*) I'd presumed
The compiler used to give the (maximal) size of a variant record type for all
its subtypes statically selecting one of the variant, if the variant record
type has a representation clause that doesn't cover all the fields. This is
fixed by the attached patch.

the patch somehow affects all of libgcc, verified by
diffing the build-logs around this commit.
Correction: it affects those parts that are not fp-bit.c, so
just the unwinder and the target-specific libgcc parts. I
This change is aimed at eliminating some access checks that are superfluous
because the access object that is subject to the check can never be null.
The 1st part makes it so that no access check is generated for the dereference
of a temporary created to hold the 'Reference of some object:
The list container maintains a pair of array index components, First and Last,
to keep track of the first and last nodes of the linked list. For an empty
list, the First and Last values should be 0. Operation Move empties the Source
container as it copies elements from the Source to the Target.
Applied, based on a conversation with Mark.

Hi,

essentially it works because of these lines in dump_expr:

case BOUND_TEMPLATE_TEMPLATE_PARM:

break;
note, however, that this means TEMPLATE_TEMPLATE_PARM
This implements assembler drop-in replacement for 64-bit division/remainder.
The original libgcc implementation is extremely resource gulping because it
uses inline in several places and DImode is resource gulping, anyway.
