From 6e1b8128505711276a87e96f6bffb818b435cbd5 Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Wed, 30 May 2012 00:17:12 +0000 Subject: Add an insertPass API to TargetPassConfig. Besides adding the new insertPass function, this patch uses it to enhance the existing -print-machineinstrs so that the MachineInstrs after a specific pass can be printed.
