How to jump to labels which are defined in C code

Hi Scott:

But I can't find the corresponding code in Disassembly window.

So it might be optimized, am I right?

But my optimization level is -O0.

Can you help me to try the code?

SOURCE CODE

void Fast_Copy_In_ASM(alt_u32* pSource, alt_u32* pDest, alt_u32 length)

{

asm volatile (

"Fast_Copy_In_ASM_Loop1: ldwio r7,0(r4)"

" stwio r7,0(r5)"

" addi r5,r5,4"

" addi r4,r4,4"

" addi r6,r6,-4"

" bne r6,zero,Fast_Copy_In_ASM_Loop1 " \

);

//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

}

Disassembly code

Thanks a lot!
