From 214a88768d34079b70e0f2ba37b91a3b717fddbb Mon Sep 17 00:00:00 2001 From: Michael Davidson Date: Tue, 21 Jan 2014 12:32:23 -0800 Subject: x86, relocs: Add manual debug mode Improve the debuggability of relocations output. When trying to compare the output between different linkers, it's handy to be able to see the section names in output.
