Upstream GCC5 isn't ported to Blackfin properly. >>> For building linux-next with allmodconfig by upstream gcc5, at present, I found 2 issues totally, and report them to upstream gcc bugzilla: - For stacktrace.c issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65804 "blackfin: Not support global frame pointer with -fno-omit-frame-pointer" - For coredump issues (for duplication reason, only report one, now): https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65803 "blackfin: internal compiler error: segment fault linux kernel" At least, I shall try to fix the coredump issues within this month ( although at present, I guess, I can not send patch v1 for it within 2015-04-20).
