And declare it in bits/cmathcalls.h as included from complex.h, rather than in math.h. With an appropriate custom RUN_TEST_LOOP_* macro that deals with the different order of expected results you should be able to put the tests in libm-test-sincos.inc, sharing the array of expected results with that for sincos rather than needing to generate a separate file of expected results with sin and cos swapped. Presumably you'd want the various type-generic templates for complex functions using M_SINCOS to move to using (an implementation-namespace name for) the faster interface, but that could be a separate patch. -- Joseph S.
