svn commit: r255381 - projects/arm_eabi_vfp/contrib/llvm/tools/clang/lib/Driver

New Revision: 255381
URL: http://svnweb.freebsd.org/changeset/base/255381

Log:
  Set the default ABI to the softfp version on armv6. This is compatible with
  the existing ABI as it passes floating-point values in ARM regsters. It is
  allowed to use VFP instructions as required instead of calling into the
  softfloat code.
