Created attachment 331190 [details] build.log When emerging coreutils with CFLAGS="-march=native", one of the valgrind tests fails with the following error vex amd64->IR: unhandled instruction bytes: 0xC5 0xFA 0x10 0x45 0x8 0x48 0x89 0xDF ==21470== valgrind: Unrecognised instruction at address 0x40b488. ==21470== at 0x40B488: hash_initialize (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ==21470== by 0x408E3F: hash_init (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ==21470== by 0x40396F: main (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ==21470== Your program just tried to execute an instruction that Valgrind ==21470== did not recognise. There are two possible reasons for this. ==21470== 1. Your program has a bug and erroneously jumped to a non-code ==21470== location. If you are running Memcheck and you just saw a ==21470== warning about a bad jump, it's probably your program's fault. ==21470== 2. The instruction is legitimate but Valgrind doesn't handle it, ==21470== i.e. it's Valgrind's fault. If you think this is the case or ==21470== you are not sure, please let us know and we'll try to fix it. ==21470== Either way, Valgrind will now raise a SIGILL signal which will ==21470== probably kill your program. ==21470== ==21470== Process terminating with default action of signal 4 (SIGILL) ==21470== Illegal opcode at address 0x40B488 ==21470== at 0x40B488: hash_initialize (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ==21470== by 0x408E3F: hash_init (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ==21470== by 0x40396F: main (in /gob/portage/tmp/portage/sys-apps/coreutils-8.20/work/coreutils-8.20/src/cp) ./tests/cp/fiemap-FMR.sh: line 28: 21470 Illegal instruction valgrind --quiet --error-exitcode=3 cp j j2
I think possibly the fact I have USE=gmp enabled is relevant

sounds like a valgrind problem
(In reply to comment #1) > I think possibly the fact I have USE=gmp enabled is relevant 1) What's your current version of valgrind: `valgrind --version` 2) Leaving everything else the same, can you try '-march=nocona' and see if this works, but '-march=native' doesn't. 3) If you are not using the latest valgrind 3.8.1, please upgrade and try again, both '-march=nocona' and '-march=native' 4) Let me see your cpu flags: `cat /proc/cpuinfo` I'm working on the theory that this is the old avx problem: bug #398447
