Here, because we're inside a member function, resolvable_dummy_lambda
thought we could resolve a reference to 'this'. But because it's a
static member function, we can't. Using nonlambda_method_basetype
instead of current_nonlambda_class_type fixes that, but then I needed
to improve n_m_b to hand
The new mangling scheme for PowerPC now uses "u9__ieee128" as the mangled name
instead of "U10__float128". This would break old code that used __float128 and
called to libraries built with the new compiler.
This patch adds a hook to emit a weak reference for the old mangled name when

IEEE 128-bit long double is mangled as "u9__ieee128".

Hi all,
The SSHL and USHL instructions are used with a shift operand of zero to
sign and zero-extend integer vectors into wider modes.
GCC makes extensive use of them to "unpack" vectors.
AArch64 defines a shorthand alias for that case. Instead of writing:
SSHLL ., ., 0
we can write
SXTL ., .
