Bug ID: 68753 Summary: PowerPC: double precision reciprocal estimate missed optimisations Product: gcc Version: 6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: anton at samba dot org Target Milestone: --- Created attachment 36939 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36939&action=edit Test cases POWER6 and above should use reciprocal estimate instructions for double precision. Attached is a set of test cases based on our single precision ones. Some of them fail.
