From 20edaa8e7791b9c33fa1a6abbca7bec3df4564ca Mon Sep 17 00:00:00 2001 From: Ken Raeburn Date: Tue, 26 May 1992 03:23:53 +0000 Subject: [PATCH] Lots of changes from gas-bfd work. Includes: * working reloc lookup support * better support for creation of COFF files from scratch * misc doc changes, macro tweaks, "const" additions, typo fixes, etc. * one or two ugly kludges that should get cleaned up (but what's one or two more, in BFD?)
