Is this something that you want to match an existing compiler? For
example GCC supports redefine_extname and extern_prefix pragmas (see
http://gcc.gnu.org/onlinedocs/gcc/Symbol_002dRenaming-Pragmas.html#Symbol_002dRenaming-Pragmas)
though the prefered way to change the assembly language name of a function is
with the 'asm' keyword
(http://gcc.gnu.org/onlinedocs/gcc/Asm-Labels.html#Asm-Labels).
These GCC features should work already in Open64 since Open64 uses the
GCC front-end. But in all these cases the source code always refers to
the old_func_name and it is only down at the assembly language level
that you would see new_func_name. That may not be what you are looking
for.
