Hello.
This patch removes obsolete GO_IF_MODE_DEPENDENT_ADDRESS macros from H8300
back end in the GCC and introduces equivalent TARGET_MODE_DEPENDENT_ADDRESS_P
target hook.
Regression tested on h8300-unknown-elf with no new failure.

The LTO partitioning code asserts that at most the first partition
is empty (which should probably be also the last one). It works

Thus, committed as obvious.

The impact of patches 4-9 of the patch set on the example from the bug
report for ARM Thumb-2 -Os is a further size reduction of 7%, from 58 to
54 bytes.
This size reduction is illustrated in this diff of the assembly
(left, without patches, size 58. right, with patches, size 54):

Currently uses and clobbers are counted as insns in crossjumping, which
can cause undesirable crossjumping. The patch fixes this.
Thanks,

This version results in about a .15% compile-time slowdown. In return
we get better code generation (size speed) through improved
inheritance and more

This patch fixes the various bugs that showed up with subversion id 171341 on
the powerpc relating to vector support.
I did a bootstrap and make check. The following tests now pass on a power7
linux/gnu system with these patches, and there were no regressions. Is it ok
to install the patch?
Inserts use of return register in epilogue threading, to keep
representation consistent, and prevent mismatch in crossjump matching.

OK. Note that it would have helped if you mentioned that bb was a
loop invariant and thus ev and ev2 were loop invariants that could
be replaced by bb.
Please install.. Thanks,

Allows crossjump over fallthru paths.

Allow crossjumping in both directions. Crossjump was assumed to be
symmetric, and therefore only applied on edges e1,e2 and not on e2,e1.
Now given both the fallthru fix and the regnotes fix, crossjumping is
not symmetrical anymore, and we allow both directions (but not by
testing twice).
Thanks,

I think this is a candidate to backport to libstdc++-4.6.1.
exception_ptr.h needs the forward declaration because it's
included from typeinfo before typeinfo defines std::type_info.
Tested:
`make check` in x86_64-unknown-linux-gnu/libstdc++-v3. The
abi_check test fails, but also did before
