LM4F232 - trying to convert blinky demo to inline assembly

trying to modify the blinky demo using inline assembly... basically just trying to replicate the loop, delays, and port register OR-ing

p.s. are there CODE tags for this forum so the code looks better?

here's the non-functional assembly:

============================================================================

    	/*__asm(
    			"start1: \n"
    			//" LDR r1, #0x400263FC \n"
    			" ORR [r0, #0x400263FC], [#0x400263FC], #0x04 \n"
    			" STR [0x400263FC], r1 \n"
    			" mov r0, #100 \n"
    			"loop1: \n"
    	"			SUB r0,#1 \n"
    	"					CMP  r0,#0 \n"

 "   						BNE  loop1 \n"
    			" and  0x400263FC, 0x0 \n"
    			" mov r0, #100 \n"
    			"loop2: \n"
    	"			SUB r0,#1 \n"
    	"					CMP  r0,#0 \n"

 "   						BNE  loop2 \n"
    			" B start1 \n"
    			);
    	*/

here's the working C from the Stellaris CD:

#include "inc/lm4f232h5qd.h"

int
main(void)
{
    volatile unsigned long ulLoop;

    //
    // Enable the GPIO port that is used for the on-board LED.
    //
    SYSCTL_RCGC2_R = SYSCTL_RCGC2_GPIOG;

    //
    // Do a dummy read to insert a few cycles after enabling the peripheral.
    //
    ulLoop = SYSCTL_RCGC2_R;

    //
    // Enable the GPIO pin for the LED (PG2).  Set the direction as output, and
    // enable the GPIO pin for digital function.
    //
    GPIO_PORTG_DIR_R = 0x04;
    GPIO_PORTG_DEN_R = 0x04;

    //
    // Loop forever.
    //
    while(1)
    {
        //
        // Turn on the LED.
        //
        GPIO_PORTG_DATA_R |= 0x04;

        //
        // Delay for a bit.
        //
        for(ulLoop = 0; ulLoop < 200000; ulLoop++)
        {
        }

        //
        // Turn off the LED.
        //
        GPIO_PORTG_DATA_R &= ~(0x04);

        //
        // Delay for a bit.
        //
        for(ulLoop = 0; ulLoop < 200000; ulLoop++)
        {
        }

    }
}
