From 5fa17e83985a0659427cd5e085ca4bd331c07f8c Mon Sep 17 00:00:00 2001 From: Cyrill Gorcunov Date: Fri, 16 Nov 2012 22:57:07 +0400 Subject: output: Add more Elf unification One day the elf output routines would be abstracted enough to be merged in one file. This patch simply removes some differences from elf32/64 code.
