Unfortunately, this patch broke SPARC bootstrap since it lost the
HAVE_cc0 guard around link_cc0_insns:
/vol/gcc/src/hg/trunk/local/gcc/reorg.c:164:1: error: 'void
link_cc0_insns(rtx)' defined but not used [-Werror=unused-function]
link_cc0_insns (rtx insn)
^
cc1plus: all warnings being treated as errors
make[3]: *** [reorg.o] Error 1
I'll install the obvious patch once testing on sparc-sun-solaris2.11 has
gotten into stage 3.
