Hi,
this is a regression present on the mainline and 6 branch: the compiler now
generates wrong code for the attached testcase at -O because of an internal
conflict about boolean types. The sequence is as follows. In .mergephi3:
boolean _22;
p__enum res;
:
if (_22 != 0)
goto ;

This patch shifts earlier the point during compilation where the
rs6000 backend adds decoration to symbols: to encode_section_info.
AIX uses the XCOFF file format, which extends COFF in a few ways,
including some increased granularity of sections through a mechanism
called Storage Mapping Class --

How about splitting out the bail-out code into a separate function:

Having discovered how fortran buffers errors, I think this approach is
necessary. I think I'm going to be in assignment-limbo for a little while though
This refactors propagation vs. substitution and handles condition
simplification properly as well as passing a known taken edge down
to the DOM walker (avoiding useless work and properly handling PHIs).
If we do all the work it's stupid to not fold away dead code...

We are incorrectly requiring unique_ptr deleters to be copyable here:
explicit
unique_ptr(pointer __p) noexcept
: _M_t(__p, deleter_type())
{ }
We could just do:
explicit
unique_ptr(pointer __p) noexcept
: _M_t()
{ std::get<0>(_M_t) = __p; }

This typedef uses the type before it's complete, which Clang rejects.
It's not necessary anyay, we can just use decltype directly where
needed. The _Invoker type isn't user-facing and doesn't need a
result_type.

This is a very simple change, to allow conversions that are supposed
to be valid according to DR 2118. The fix was slightly complicated by
the tests being a bit of a mess. We had tests for this requirement,
but they were in files which mixed positive tests and negative tests.
I've split the tests
In C++17 the emplace_front and emplace_back members return a
reference. There isn't a very neat way to implement this, so it's just
lots of conditional compilation.
This isn't an ABI break, because these member functions are templates
and so the return type is part of the mangled name. We can't a
