Summary: [4.6 regression] bootstrap failure due to warnings in
compare-elim.c
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mikpe@it.uu.se
Bootstrapping 4.6-20110122 on powerpc64-linux fails with:
/mnt/archive/gcc-4.6-20110122/gcc/compare-elim.c: In function
'maybe_select_cc_mode':
/mnt/archive/gcc-4.6-20110122/gcc/compare-elim.c:407:58: error: unused
parameter 'b' [-Werror=unused-parameter]
cc1: all warnings being treated as errors
make[3]: *** [compare-elim.o] Error 1
make[3]: *** Waiting for unfinished jobs....

make[3]: Leaving directory `/mnt/archive/objdir46/gcc'

make[2]: Leaving directory `/mnt/archive/objdir46'
make[1]: *** [stage2-bubble] Error 2
make[1]: Leaving directory `/mnt/archive/objdir46'
make: *** [bootstrap] Error 2
The problem is that the rs6000 SELECT_CC_MODE macro ignores its last parameter,
so the 'b' parameter to maybe_select_cc_mode is unused, triggering the error.
Targets without SELECT_CC_MODE (e.g. m68k) also break, see
<http://gcc.gnu.org/ml/gcc-patches/2011-01/msg01607.html>.
