I'd suggest not wasting more than one day on a issue. If you cannot solve the problem in that time, come up and ask; for example in a place like here. > Asking for the critical bits on avr-gcc brought up basically nothing, > which suggests to me nobody really actually knows. You can browse the http://gcc.gnu.org/bugzilla bug data base for information on desired target, compiler version and bug status. For 4.6.2 there are PR50807: Corner case, not really important. PR50063: Not so nice but -fno-dse fixes it. If you are doing distributions, you can disable it by setting flag_dse = 0 in GCC-SOURCE/gcc/config/avr/avr.c::avr_option_override() PR46261: -mint8 crashes avr-gcc > Unless there is better information beginners will definitely not try new > versions for a plain practical reason: can't build, can't no do. > > I'll post more information later in the hope someone will be able to put > it up in some obvious place on the avr-gcc project pages. > > Volker _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
