__CSKY_HARD_FLOAT_ABI__ was added on gcc 11 to specify whether -mfloat-abi=hard is set. On older gcc, the float ABI is defined solely with __CSKY_HARD_FLOAT__. If __CSKY_HARD_FLOAT__ is set, it can be either a hard-float ABI (gcc older than 11, or gcc11 -mfloat-abi=hard (__CSKY_HARD_FLOAT_ABI__ is set) or -mfloat-abi=softfp (__CSKY_HARD_FLOAT_ABI__ is not set). To be compatible with older gcc, use __CSKY_HARD_FLOAT_FPU_SF__ identify if -mfloat-abi is supported, because it is added to gcc at the same time as -mfloat-abi.
