From f7e7b938ea6debf600d2147331c0e90ca35595ed Mon Sep 17 00:00:00 2001 From: Dean Michael Berris Date: Tue, 3 Jan 2017 04:30:21 +0000 Subject: [XRay] Merge instrumentation point table emission code into AsmPrinter. Summary: No need to have this per-architecture. While there, unify 32-bit ARM's behaviour with what changed elsewhere and start function names lowercase as per the coding standards. Individual entry emission code goes to the entry's own class. Fully tested on amd64, cross-builds on both ARMs and PowerPC.
