This patch should restore bootstrap on hppa (and probably other targets
besides). The change to use target-insns.def put more stress on the
emit()/classify_insn() group of functions, which were missing a case
for parallel returns.
Tested with a cross-compiler that it fixes the hppa problem. Bootstrap
in progress on x86_64-linux-gnu. OK to install?
Sorry for the slow response on this one. I'd misread the PR and thought
that it was the bug fixed in r225000.
Thanks,
Richard
