Enabling IRQ and FIQ

Hi ,
I am using TMS570LS20216 USB Kit, I am trying to enable the FIQ and IRQ using the below assembly function :

/* To Enable the FIQ */
_enable_FIQ();

/* To Enable the IRQ*/
 _enable_IRQ();

The above mentioned function definitions are as below:
As mentioned in the spnu489c.pdf

FIQENABLE .equ 0x40
IRQENABLE .equ 0x80
......
_Enable_Fiq
MRS R1, CPSR
BIC R1, R1, #FIQENABLE
MSR CPSR, R1
MOV PC, LR
......

_Enable_Irq
MRS R1, CPSR
BIC R1, R1, #IRQENABLE
MSR CPSR, R1
MOV PC, LR

I would like to know if there is a way to access these CPSR and  General Purpose (example: R1) registers using C language?
