MSP432P401R: Using the FPU coprocessor

Part Number: MSP432P401R

1. Is there a description of what the compiler options are in Code Composer Studio for choosing the Floating Point Processor on an MSP432?

I could not find the descriptions in the Code Composer Studio manuals.

In particular a description of what the options are under the CCS menu  CCS Build >> MSP432 Compiler >> Processor Options "Specify floating point support"

2. To use the floating point processor in a MSP432P401R program

Does the field in the startup file "system_msp432p401r.c" have to be set to use the FPU?

So adding a line

#define __FPU_USED         1 

 to the file "system_msp432p401r.c" forces the FPU to be used or is the
__FPU_USED already selected in the header file "core_cm4.h" based on the 

specific chip used, in this case and MSP432P401R, which does contain a FPU inside?

void SystemInit(void)
{
    // Enable FPU if used
    #if (__FPU_USED == 1)                                  // __FPU_USED is defined in core_cm4.h
    SCB->CPACR |= ((3UL << 10 * 2) |                       // Set CP10 Full Access
                   (3UL << 11 * 2));                       // Set CP11 Full Access
    #endif
