Gcc report warning as follows:
arch/arm/nwfpe/softfloat.c: In function ‘floatx80_rem’:
arch/arm/nwfpe/softfloat.c:3071:17: error: variable ‘bSign’
set but not used [-Werror=unused-but-set-variable]
arch/arm/nwfpe/softfloat.c: In function ‘float64_rem’:
arch/arm/nwfpe/softfloat.c:2247:17: error: variable ‘bSign’
set but not used [-Werror=unused-but-set-variable]
arch/arm/nwfpe/softfloat.c: In function ‘float32_rem’:
arch/arm/nwfpe/softfloat.c:1349:17: error: variable ‘bSign’
set but not used [-Werror=unused-but-set-variable]
Only assign value to variables "bSign", no final use. Fix by
removing them.
