The unrecognizable insn is a "tail call". In 2013.05 release, it matches "sibcall_value_insn". But in 2013.06 release, it can not match it.
Recently there were some changes for "tail call". 2013.06 release might merge some of the changes. Please try FSF trunk, if it also fails, please submit a bug against FSF trunk. ** Changed in: gcc-linaro Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1194501 Title: ICE on gcc-4.8 building kde4libs To manage notifications about this bug go to: https://bugs.launchpad.net/gcc-linaro/+bug/1194501/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
