Bug ID: 107279 Summary: __builtin_complex is not supported Product: gcc Version: 12.0 Status: UNCONFIRMED Keywords: documentation Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: pinskia at gcc dot gnu.org Target Milestone: --- I noticed this while trying to create a testcase for another issue. And it is not documented that __builtin_complex is only support for the C front-end (I know because I touched the documentation last). testcase: ``` void f(void) { _Complex float a = __builtin_complex (1.0f, 2.0f); } ```
