From d1b4a3451e03e09966fa9700584e38baece8d3cd Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Fri, 14 Oct 2016 05:37:34 +0200 Subject: [PATCH] gallivm: print out time for jitting functions with GALLIVM_DEBUG=perf Compilation to actual machine code can easily take as much time as the optimization passes on the IR if not more, so print this out too.
