From 897a12cd26ad01a5ef19474f23cfd0fbff4ea5a7 Mon Sep 17 00:00:00 2001 From: Mike Wittman Date: Mon, 11 Dec 2017 13:50:41 -0800 Subject: Write field indicating multiple symbols at an address in dump_syms Updates dump_syms to write the optional 'm' first field in FUNCTION and PUBLIC records to indicate that the address corresponds to more than one symbol.
