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?
Ok.
I think this has probably broken bootstrap on powerpc64, where sibcalls
have both calls and returns. The loop picks the last candidate,
which is the return.
Is this patch OK?
Thanks,

* rtl.c (classify_insn): Only return JUMP_INSN for parallel returns if
there are no CALLs in the same pattern.
OK.
