--- Comment #12 from David Edelsohn <dje at gcc dot gnu.org> ---
The assembly file should start with

.machine power4

which is the lowest level ISA supported on PPC64 Linux, GLIBC and mtfsf.

If one invokes GCC with multiple -m options, it is complicated to calculate the
correct assembler command line option, especially at the point that the
assembler command is generated.  With an assembler file, the compiler has no
knowledge about the contents and should not guess the required ISA.
