Simple algorithm, just look for the next backward jump that points to before the cursor. Then draw an arrow connecting the jump to its target. Do this as you move the cursor, entering/exiting possible loops.

If you want to build and install it, do $ make tools/<toolname>_install $ make tools/<toolname>_clean should clean the respective tool directories.

This patch prints the number of samples and the count of performance events separately. This allows comparing performance of different applications with each other. Previously, the sample count was displayed against an 'Events:' heading. With this patch, the header now reads (for example): Samples: 5K of event 'instructions' Event count (approx.): 2993026545 The patch covers both the stdio and the browser interface. Signed-off-by:
