neon example
Hi, there:
When debugging code on aarch64, I find gdb can't print neon register correctly.
I've a simple example attached:
#define SIZE 8
int main(void)
{
char arr[SIZE] = {0, 1, 2, 3, 4, 5, 6, 7};
asm volatile("ld1 {v0.8b}, [%0], 8"::"r"(arr):"v0", "memory");
}
after running the 'ld1' instruction, the v0.8b value in gdb is:
s = {4, 5, 6, 7, 0 <repeats 12 times>}
While the true value should be:
s = {0, 1, 2, 3, 4, 5, 6, 7}
