To be clear: given this mangling (which certainly simplif
This patch changes the (C++) mangling of the 128-bit float types.
IBM long double ("double-double") is mangled as "g", as before, and
IEEE 128-bit long double is mangled as "u9__ieee128".
Bootstrapped and tested on powerpc64-linux {-m32,-m64} (Power7) and
on powerpc64le-linux (Power9). Also teste

^^ what is the advantage/reason for the above, rather than mangling it
as g?

__ibm128 becomes u8__ibm128
of course.

This patch changes the (C++) mangling of the 128-bit float types:
__ieee128 becomes u9__ieee128
__ibm128 becomes u8__ieee128
__float128 is not a type anymore
IEEE long double becomes u9__ieee128
IBM long double stays g
This is a necessary ABI break. It wil
