Attempting to bootstrap gcc-4.6-20100814 (r163252) on arm-linux-gnueabi fails
due to a warning in stage2 and the default use of -Werror there:
/home/mikpe/gcc-4.6-20100814/gcc/config/arm/arm.c: In function
'arm_get_pcs_model':
/home/mikpe/gcc-4.6-20100814/gcc/config/arm/arm.c:3720:7: error: passing
argument 1 of 'stdarg_p' discards 'const' qualifier from pointer target type
[-Werror]
/home/mikpe/gcc-4.6-20100814/gcc/tree.h:4829:13: note: expected 'tree' but
argument is of type 'const_tree'
cc1: all warnings being treated as errors
make[3]: *** [arm.o] Error 1
make[3]: Leaving directory `/home/mikpe/objdir46/gcc'
make[2]: *** [all-stage2-gcc] Error 2
make[2]: Leaving directory `/home/mikpe/objdir46'
make[1]: *** [stage2-bubble] Error 2

Presumably caused by r163033:

The right solution seems to be to make stdarg_p accept a const parameter, but then the problem is that the parameter is stored in the iterator's fntype field. Nothing uses that field, so removing it and then making the parameter const fixes the issue. ARM bootstrap still fails for me with comparison failures, however. (I'm in an email black hole at the moment so can't easily submit this to gcc-patches.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45321 ^ permalink raw reply [flat|nested] 6+ messages in thread
