# This file is generated from configure.ac by Autoconf.  DO NOT EDIT!
 # Local configure fragment for sysdeps/arm.

# We check to see if the compiler and flags are
# selecting the hard-float ABI and if they are then
# we set libc_cv_arm_pcs_vfp to yes which causes
# HAVE_ARM_PCS_VFP to be defined in config.h and
# in include/libc-symbols.h and thus available to
# shlib-versions to select the appropriate name for
# the dynamic linker via %ifdef.
