[LLVMdev] [LLVMDev] Number of loops in a region (original) (raw)

Hi,

I was wondering if there is a way to count the number of loops contained in a region.

For example in a program like this:

for (int i = 1; i < MAX; ++i) { x[i] = x[i - 1]; }

for (int i = 0; i < MAX; ++i) { y[i] = y[i] + 1; }

fun();

for (int i = 0; i < MAX; ++i) { x[i] = x[i] + 1; }

in my understanding the regions would be 2, the first one with the first 2 loops and the second one with the last loop.

Is it also possible to get a region with one loop at time?

Thanks. Best, Simone
