From baa7787a1615684fed0bcb39383aab75f401c649 Mon Sep 17 00:00:00 2001 From: ed Date: Sat, 25 May 2013 18:55:55 +0000 Subject: Add C11 macros CMPLX(), CMPLXF() and CMPLXL(). Clang allows us to initialize complex numbers using an array initializer, casted to a complex type. GCC has a builtin called __builtin_complex(). --- include/complex.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'include') diff --git a/include/complex.h b/include/complex.h index 0702541..e777082 100644 --- a/include/complex.h +++ b/include/complex.h @@ -46,6 +46,18 @@ _Static_assert(__generic(_Complex_I, float _Complex, 1, 0), #define complex _Complex #define I _Complex_I +#if __ISO_C_VISIBLE >= 2011 +#ifdef __clang__ +#define CMPLX(x, y) ((double complex){ x, y }) +#define CMPLXF(x, y) ((float complex){ x, y }) +#define CMPLXL(x, y) ((long double complex){ x, y }) +#elif __GNUC_PREREQ__(4, 7) +#define CMPLX(x, y) __builtin_complex((double)(x), (double)(y)) +#define CMPLXF(x, y) __builtin_complex((float)(x), (float)(y)) +#define CMPLXL(x, y) __builtin_complex((long double)(x), (long double)(y)) +#endif +#endif /* __ISO_C_VISIBLE >= 2011 */ + __BEGIN_DECLS double cabs(double complex); -- cgit v1.1
