Bug ID: 70612 Summary: -mtune=native -maes does not detect that AES is not present Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: daniel.gutson at tallertechnologies dot com Target Milestone: --- I didn't investigate this, but despite /proc/cpuinfo does not list aes as a capability, I think that the combination -mtune=native -maes should fail.
