# This check is for compatibility with GCC versions earlier than 11.
# The older versions of C-SKY GCC do not support the '-mfloat-abi=softfp' option
# and never define the '__CSKY_HARD_FLOAT_ABI__'.
# Therefore, if a check for '-mfloat-abi=softfp' is added as the expression
# 'defined(__CSKY_HARD_FLOAT__) && !defined(__CSKY_HARD_FLOAT_ABI__)'
# which is correct for newer versions of GCC will not work for those older versions.
# Since no expression compatible with all versions of GCC exists,
# a check for the '-mfloat-abi=softfp' option is added.
