Bug ID: 93871 Summary: COTAN is slow for complex types Product: gcc Version: 10.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libfortran Assignee: unassigned at gcc dot gnu.org Reporter: thenlich at gcc dot gnu.org Target Milestone: --- Runtime tests show that the COTAN function (cotangent function, GNU extension) needs about twice the time as TAN for complex types. This is surprising, since it basically performs the same operations as TAN, only in a different order. I would expect COTAN to perform about the same as TAN.
