Accesing R15 (PC)

My approach would look like this:

int getPC (void) {
  int RetVal;
  __asm {
     MOV     R0,LR
     STAV    R0,R1,RetVal
  }
  return (RetVal);
}

...

printf ("The current location of the Program Counter is 0x%08X\n", getPC());

My approach would look like this:

int getPC (void) {
  int RetVal;
  __asm {
     MOV     R0,LR
     STAV    R0,R1,RetVal
  }
  return (RetVal);
}

...

printf ("The current location of the Program Counter is 0x%08X\n", getPC());

The following is the c file, this compiles and runs fine with GNU tools:

#include <ADuC7026.h>
#include<stdio.h>

// Program Counter Defintion. Allows us to access R15.

register unsigned int R15 asm ("pc");

// Function Prototype with required function attribute.

extern void Ram_Function(void) __attribute__ ((section (".ram_func")));

int main(void)
{
// Setup tx & rx pins on P1.0 and P1.1
GP1CON = 0x011;
// Set UART to 9600bps 8-N-1
COMCON0 = 0x80; // Setting DLAB
COMDIV0 = 0x93;
COMDIV1 = 0x00;
COMCON0 = 0x07; // Clearing DLAB

//Print current program counter address ... currently executing from FLASH!!
printf("This is the main Flash Function.\n");
printf("The Current location of the Program Counter is : 0x%08X\n",R15);
Ram_Function();

return 0;
}

The output via serial cable is:

This is the main Flash Function.
The Current location of the Program Counter is : 0x0008024B


This address is correct. When i compile this c file using the Keil Tools however, i get the following error message:

register unsigned int R15 asm ("pc");

I have called the function from assembley as described by Matthias above and this does work under Keil tools. Is there a way i can get it working without javing to do this though?

Apologies, the original line i posted:

printf("The Current location of the Program Counter is : 0x%08X\n","PC");

was incorrect, it should have read

printf("The Current location of the Program Counter is : 0x%08X\n",R15);

i had changed the line as an experiment to try get the code working and forgot to change it back
