Hello.
Following error message can be seen for LTO boostrap:
../../gcc/fortran/resolve.c:3812:1: error: type ‘comparison’ violates one
definition rule [-Werror=odr]
comparison;
^
../../gcc/compare-elim.c:95:0: note: a different type is defined in another
translation unit
rtx_insn *insn;
^
lto1: all warnings being treated as errors
lto-wrapper: fatal error: /home/marxin/Programming/gcc3/objdir/./prev-gcc/xg++
returned 1 exit status
I've removed enum type in resolve.c, which is quite small change (I hope so).
With patch applied, GCC can bootstrap.
Ready for trunk?
Thanks,
Martin
