From 620bbba524fbaa26971a5004793010b169824f1b Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Tue, 15 Jun 2010 21:48:25 +0200 Subject: examples/standalone: Remove relocation compile flags for PowerPC Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications. Additionally, removing the gcc relocation flags results in the entry point of applications residing at the base of the image. When a standalone application was relocatable, the entry point was generally located at an offset into the image which was confusing and prone to errors. This change moves the entry point of PowerPC standalone applications from 0x40004 (usually) to 0x40000.
