# 266314 17-May-2014 ian

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.


# 266133 15-May-2014 ian

MFC r257207, r261161, r261163:

Update the hard-float version of the fenv functions to use the VFP unit.
Any other floating-point unit is unsupported on ARM.

Use __fenv_static for all static inline functions.

Correctly shift the mask when masking/unmasking exceptions.
