From 7ec830d5804337afe19413c3eaedd16583af9076 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Tue, 29 Mar 2011 14:34:50 +0200 Subject: [PATCH] Fix build problems caused by "_end" -> "__bss_end__" rename Commit 44c6e65 "rename _end to __bss_end__ broke building of a large number of systems (at least all PowerPC?): libstubs.o: In function `app_startup': examples/standalone/stubs.c:197: undefined reference to `__bss_end__' The rename should not be done for the files in the examples/standalone/ directory, as these are not using the code from start.S, but do their own BSS clearing, and either use their own linker scripts or the ones provided by the compilers.
