In line assembler issue Xilinx XSDK for Zynq

I am trying to compile an application developed with the ARM DS-5 tools the Xilinx XSDK (14.04) IDE and compiler.

I have run into an in-line assembly code issue that seems to compile correctly on the ARM DS-5 ide but fails on the XSDK.

 

The module is in a directory “XilinxCode".

The code is in the file “xpseudo_asm_rvct.h” and has a 2009 Xilinx Copyright header.

 

The code segment in question:

 

static __inline unsigned long mfcpsr(void)

{

    register volatile unsigned int Reg __asm("cpsr");

    return Reg;

}

#endif

#define mtcpsr(v)        { register volatile unsigned int Reg __asm("cpsr");\

                                      Reg = v; }

 

The error message that I am getting is:

invalid register name for 'Reg'

 

I am new to low level bare metal programming and have no experience with in-line assembly. Anny help would be appreciated.
