Bug ID: 86772 Summary: [meta-bug] tracking port status for CVE-2017-5753 Product: gcc Version: 9.0 Status: UNCONFIRMED Keywords: meta-bug Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: rearnsha at gcc dot gnu.org Target Milestone: --- This is a meta bug to track the port status of all ports that have not yet been updated to handle CVE-2017-5753 (Spectre variant 1). If your port does (or might in the future) need to mitigate against unsafe speculation, then you will need to define (at a minimum) a "speculation_barrier" insn. If your port does not (and never will in the future) need to mitigate against unsafe speculation, you can simply add #undef TARGET_HAVE_SPECULATION_SAFE_VALUE #define TARGET_HAVE_SPECULATION_SAFE_VALUE speculation_safe_value_not_needed. to your target defines.
