There are many places in GCC where alternative local sequences are
tried in order to determine what is the cheapest or best alternative
to use in the current target. When any of these sequences involve a
libcall, the current implementation of emit_library_call_value_1

There are many places in GCC where alternative local sequences are
tried in order to determine what is the cheapest or best alternative
to use in the current target. When any of these sequences involve a
