Use macro for function declaration and weak_alias. * sysdeps/ieee754/flt-32/s_cosf.c (COSF, COSF_FUNC): Add macros for using routine as __cosf_ia32. Use macro for function declaration and weak_alias. * sysdeps/i386/i686/fpu/multiarch/e_expf-sse2.S: Fix Copyright. * sysdeps/i386/i686/fpu/multiarch/e_expf.c: Fix Copyright. * sysdeps/x86_64/fpu/s_sinf.S: New file. * sysdeps/x86_64/fpu/s_cosf.S: New file. * sysdeps/x86_64/fpu/libm-test-ulps: Update. * math/libm-test.inc (cos_test): Add more test cases. (sin_test): Likewise. (sincos_test): Likewise. --- sysdeps/i386/i686/fpu/multiarch/s_cosf.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 sysdeps/i386/i686/fpu/multiarch/s_cosf.c (limited to 'sysdeps/i386/i686/fpu/multiarch/s_cosf.c') diff --git a/sysdeps/i386/i686/fpu/multiarch/s_cosf.c b/sysdeps/i386/i686/fpu/multiarch/s_cosf.c new file mode 100644 index 0000000000..f07c3e5103 --- /dev/null +++ b/sysdeps/i386/i686/fpu/multiarch/s_cosf.c @@ -0,0 +1,29 @@ +/* Multiple versions of cosf + Copyright (C) 2012 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
