From 8136aefd779ccd98470aa9ef6ffd5f38aaee9568 Mon Sep 17 00:00:00 2001 From: Craig Topper Date: Thu, 14 Mar 2019 01:13:15 +0000 Subject: [PATCH] [ResetMachineFunctionPass] Add visited functions statistics info Adding a "NumFunctionsVisited" for collecting the visited function number. It can be used to collect function pass rate in some tests, the pass rate = (NumberVisited - NumberReset)/NumberVisited. e.g. it can be used for caculating GlobalISel pass rate in Test-Suite.
