From 3a129c85920404e7ccdb7e655c89fa60a0309cfd Mon Sep 17 00:00:00 2001 From: Andrew Kaylor Date: Wed, 10 Oct 2012 01:41:33 +0000 Subject: This patch adds new functions to the SectionRef and ObjectFile interfaces to determine whether or not a section is meant to be read-only. These functions will be used by the MCJIT RuntimeDyld to give hints to the memory manager during the object loading process in a future patch.
