How to jump to labels which are defined in C code

Hi Scott:

I have tried your code, no compiling error occurred,but something was wrong.

The following code work fine.

asm("Fast_Copy_In_ASM_Loop: ldwio r7,0(r4)");

asm("stwio r7,0(r5)");

asm("addi r5,r5,4");//increase read_data to point to next byte

asm("addi r4,r4,4");//increase read_data to point to next byte

asm("addi r6,r6,-4");//decrease read_length

asm("bne r6,zero,Fast_Copy_In_ASM_Loop");//CWG2

But the code you showed me were all skipped when I step into it.

asm volatile (

"LOOP: ldwio r7,0(r4)"

" stwio r7,0(r5)"

" addi r5,r5,4"

" addi r4,r4,4"

" addi r6,r6,-4"

" bne r6,zero,LOOP " \

);

WHY?

best regards,

David
