Author: ian Date: Sat May 17 14:22:37 2014 New Revision: 266314 URL: http://svnweb.freebsd.org/changeset/base/266314 Log: MFC 262989, 263210, 263230, 263231, 263239, 263242, 263243, Export _libc_arm_fpu_present as a private symbol to be used by other system libraries, for example libm. On armv6 access both the softfloat and, when available, the vfp to get and set the floating-point environment. Build fenv-vfp.c with the softfp float abi. Without this gcc generates an incorrect assembly file that doesn't allow for vfp instructions. Only build the vfp/softfp switching code on armv6 as we don't support vfp on anything earlier than this. This should fix the armeb and arm builds when using gcc. Add an optimised version of the float and double helper functions.
