This is a follow-up to
https://gcc.gnu.org/pipermail/gcc-patches/2024-September/662725.html

I basically added only some documentation to the first patch.  If you
think that gcc/doc/extend.texi isn't the right place (especially the
discussion part which will be dropped/rephrased in the end anyway), then
just let me know.

Stefan Schulze Frielinghaus (4):
  Hard register constraints
  Error handling for hard register constraints
  genoutput: Verify hard register constraints
  Rewrite register asm into hard register constraints
