From d435569cd626bccb9c27361202a279d0fd7fce88 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 11 Feb 2015 23:17:25 +0000 Subject: Fix sincos errno setting (bug 15467). This patch makes sincos set errno to EDOM when passed an infinity, similarly to sin and cos. Tested for x86_64, x86, powerpc and mips64. I don't know if the architecture-specific implementations for ia64 and m68k might need corresponding fixes. 2015-02-11 Joseph Myers [BZ #15467] * sysdeps/ieee754/dbl-64/s_sincos.c: Include . (__sincos): Set errno to EDOM for infinite argument. * sysdeps/ieee754/flt-32/s_sincosf.c: Include .
