I'm getting this build failure with latest trunk, as of the composing of
this email:

cc1: warnings being treated as errors
../../gcc-trunk/gcc/ira-lives.c: In function
ira_implicitly_set_insn_hard_regs:
../../gcc-trunk/gcc/ira-lives.c:748:13: error: regno may be used
uninitialized in this function
It looks like ira-lives.c:763 has some ambiguous parenthesizing that may
be causing the warning that is failing the build). Note that the warning
doesn't happen on a similar piece of code on line 830 in the same file.
I've been fighting with the configure process for a few days and finally
got past that to this issue. So, any help is greatly appreciated :)
Thanks!
