From a6d6ef6dac9407840aadf1e657ba58989946173e Mon Sep 17 00:00:00 2001 From: Jack Carter Date: Wed, 27 Jun 2012 23:13:42 +0000 Subject: [PATCH] This allows hello world to be compiled for Mips 64 direct object. It takes advantage of r159299 which introduces relocation support for N64. elf-dump needed to be upgraded to support N64 relocations as well. This passes make check.
