When reshaping the initializer for a class, if we come to a zero-length

Here, the problem was that we were resolving the address of an
overloaded function in the context of the template being called (which
doesn't have access to the function) rather than the caller (which
does). We need to massage explicit template arguments before we enter
the callee's context.
Here are some additional fixes for OpenBSD that fix a fair number of
failing testcases. I can split this up in smaller patches if that's
preferred.
I believe I submitted the openbsd-stdint.h bit before. We consistenly
use "long long" types for the *max_t types, on both 32-bit and 64-bit

I configure GCC with --enable-languages=all,obj-c++ for testing, and
this started breaking recently, because I ended up with 'c' twice in the
list of languages, so reconfiguring breaks. This seems to be because
r189080 didn't adjust the "all" case along with the language name case.

This patch works around a parsing problem with g++ 4.3. The parser is
failing to lookup calls to the template function reserve when called
from other member functions:
vec_t::reserve (...)
The parser thinks that the '<' in reserve is a less-than operation.
This problem does not happen after 4.3.

I was thinking to point out what to not use any longer, in case.
Doesn't that make sense for the release notes?

This fixes PR54458 where DOM jump threading turns a loop into
one with multiple latches but does not mark it so.
Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk.

Hi all,
I have just committed to trunk a trivial fix for two recent OOP
regressions (affecting 4.7 and trunk), both of which originate from
the same problem:
http://gcc.gnu.org/viewcvs?view=revision&revision=190910
I will commit this fix also to the 4.7 branch in a few days.
Cheers,
Janus

I've committed the attached version of the patch as rev 190909.
Cheers,

I ran regression test with/without Os for cortex-m0 and everything is ok.
Ok for trunk and 4.7/4.6 release branches?
OK for trunk.
Ok to backport if no release manager objects in 24 hours and if it tests
without regressions there.
Thanks,
Ramana
Hi Oleg,
And so I did. Attached is an updated patch that adds the address space
parameter to the address_cost function. I hope that this change does
not reset the ACKs so far:
[x] target-independent bits
[ ] alpha [ ] arm [ ] avr [ ] bfin
[ ] cr16 [ ] cris [ ] epip
