This adds more correct .machine for most older CPUs. It should be

is too risky at this point in time.
Tested on powerpc64-linux {-m32,-m64}. Also manually tested with all
-mcpu=, and the output of that passed through the GNU assembler.
I plan to commit this later today.
Could this be back ported to GCC 10 and 11? I would fix the following
issue for -mcpu=405:
Error: unrecognized opcode: `dlmzb.'
Good to hear!
Unfortunately there is PR104829 about this commit. I don't see how the
commit can break anything (that wasn't already broken); it's not clear
how it happens at all, and neither me nor colleagues could reproduce it
so far.
So I won't yet backport it, but first wait what happens here.
now that the PR104829 is fixed could I back port
Segher Boessenkool (2):
rs6000: Improve .machine
rs6000: Do not use rs6000_cpu for .machine ppc and ppc64 (PR104829)
to GCC 10 and 11?
