For example, it started with a report that had: insn-extract.c: In function 'void insn_extract(rtx_insn*)': insn-extract.c:3006: internal compiler error: internal consistency failure Please submit a full bug report, . . . (not a SIGSEGV initially). There was evidence reported of: pid 5555 (gmake), uid 0: exited on signal 11 (core dumped) pid 5540 (gmake), uid 0: exited on signal 11 (core dumped) pid 5530 (gmake), uid 0: exited on signal 6 (core dumped) pid 5529 (sh), uid 0: exited on signal 11 (core dumped) pid 3052 (make), uid 0: exited on signal 11 (core dumped) pid 612 (sshd), uid 0: exited on signal 11 pid 671 (getty), uid 0: exited on signal 11 (core dumped) (Those sure do not look like a compiler failing to run to me.) There was the vec_step issue. And so on. Both gcc5 and gcc6 are gone, as is the system gcc 4.2.1 (on head). At least head has progressed to a different powerpc64 ABI and an official llvm toolchain. If there is anything still relevant here, it might only be for FreeBSD 11 or 12 just due to the large context difference for head's powerpc64. It looks too complicated to sort out and a new submittal of material might be better (if there is a need). --=20 You are receiving this mail because: You are the assignee for the bug.=
