--- Comment #9 from David Edelsohn <dje at gcc dot gnu.org> ---
GCC is working correctly. The file prologue generated by GCC for a C file now
includes
.machine power8
The example is a pre-processed assembly file. Note the file actively pushes
and pops the machine type.
The assembly file incorrectly assumes that GCC will invoke the assembler with a
command-line option enabling a default ISA level sufficient for the
instructions in the file. This is a bad assumption. Even if we create a
kludge in GCC to invoke the assembler an arbitrary ISA level, this is bad
assumption. The GLIBC file is buggy.
