| |
Objtool is failing to build with GCC 4.4.7 due to the following warnings:
cc1: warnings being treated as errors In file included from orc.h:21, from orc_gen.c:21: orc_types.h:86: error: packed attribute is unnecessary for ‘sp_offset’ orc_types.h:87: error: packed attribute is unnecessary for ‘bp_offset’ orc_types.h:88: error: packed attribute is unnecessary for ‘sp_reg’
I suspect those warnings are a GCC bug. But -Wpacked isn't very useful anyway, so just disable it.
