Hi,
this patch fixes OBJ_TYPE_REF handling. We need to compare OTR type for match
and we can skip comparing when devirtualization is disabled.

Hi,
the prevoius bug in COMDAT handling made me to revisit the code once again.
There was few bugs fixed bellow.
1) If we have resolution info and we know original is going to be discarded
we need to prevail COMDAT logic
2) It is possible to merge non-comdat to comdat and comdat to non-comdat.
hi,
this patch fixes bug in can_inline_edge_p where opt_for_fn is taken from
inline clone and not function being inlined into itself. Those opt_for_fn
are going to be ignored and thus have no meaning.
I also fixed case wehre !flag_devirtualize would get inlined into

Hello.
This patch makes correctly decision about variables that are read-only and are
candidates
for merge operation. Tested on x86_64-unknown-linux-gnu.
Ready for trunk?
Thanks,

Richard, I wonder what happens with TYPE_ALIGN at LTO. It is not part of
canonical type
definition and thus we get random alignm

Hi,
the Chromium miscompilation is caused by introducing extra copy when returning
non-POD object (as tested in the testcase). This is bug in
cgraph_node::expand_thunk not setting gimple_call_set_return_slot_opt (I copied
same code from ipa-split).
This bug should reproduce on all release branch

This allows a target to support both windowed and non-windowed ABI.

Hello,
this series adds call0 ABI support for xtensa. Code generation part is
well tested, but I'm not 100% sure about the exception handling part.
Please review.

Ue copy relocation in PIE improves performance. But copy relocation
can't be used to access protected symbols defined in shared libaries
and linker in binutils 2.26 enforces doesn't allow it. GCC doesn't
know if an external definition is protected or not. This option adds
-mcopyreloc-in-pie to g
