By default, XRay does not write out the trace files or patch the application
-before main starts. If we just run ``llc`` it should just work like a normally
-built binary. However, if we want to get a full trace of the application's
-operations (of the functions we do end up instrumenting with XRay) then we need
-to enable XRay at application start. To do this, XRay checks the
-``XRAY_OPTIONS`` environment variable.

To generate output for a flamegraph, a few more options are necessary.
