Hi,
actually I forgot one hunk in the tree. This time it makes speculative
devirtualuzation
to consider node and its alias to be equivalent.
This happens in ipa-devirt10 becuase one of targets appears in symbol table and
thus is redirected
to alias while the second doesn't.

Hi,
this patch fixes the devirt10 and devirt15 failures - the problem was that we
did not look into alias target
when estimating devirt benefit.
Bootstrapped/regtested rs6000-aix, comitted.

Hi,
this is the last part enabling local aliases that seems to work now.
I think we can go ahead and try to enable section GC and SUPPORTS_ONE_ONLY.

This is unexpected. I am testing version of the patch with
if (lookup_attribute ("ifunc", DECL_ATTRIBUTES (n->decl)))
return false;

The problem with devirt-10 and devirt-15 is the excellent kludge for
aliases on AIX can produce multiple symbols.
ipa-prop: Discovered a virtual call to a known target (void
wxBufferedDC::InitCommon(wxDCBase*)/3 -> virtual void
wxDCBase::_ZN8wxDCBase18SetLayoutDirectionEi.localalias.6(int)/36),

Hi,
AIX as' .set pseudoop has somewhat unexpected behaviour. It seems to be
implemented by syntactically replacin all appereances of the alias by
its target (that can be an expressoin) but it is still possible to globalize
the alias by .globl operation.
This breaks the assumption we make about al
