Hi,
Yes I am using the compiler provided with tool chain. I could get rid
of the error: "misaligned branch
destination" after renaming the labels in atomicbase.h file. The
assmebler was taking those errors as absolute addresses:
The portion of code from atomicbase.h is given here:
@@ -1393,7 +1393,7 @@
" mov %0, #0x80000000;\n" /* Set ulRet to 0x80000000
*/
"1: swp %0, %0, [%1];\n" /* Swap *pNum and ulRet
*/
" cmp %0, #0x80000000;\n" /* Is someone else using pNum?
*/
-" beq 1;\n" /* If so, retry...
*/
+" beq 1b;\n" /* If so, retry... */
" add %0, %0, #1;\n" /* Increment ulRet
*/
" cmp %0, #0x80000000;\n" /* check for overflow
*/
" addeq %0, %0, #1;\n" /* if so, increment again */
