--- Comment #3 from Sriraman Tallam <tmsriram at google dot com> 2012-03-09 19:36:21 UTC --- Right, I was not looking at SECTION_MACH_DEP when I defined the macro. Is it ok to just bump SECTION_MACH_DEP? The patch I have in mind is: -#define SECTION_MACH_DEP 0x2000000 /* subsequent bits reserved for target */ -#define SECTION_EXCLUDE 0x4000000 +#define SECTION_EXCLUDE 0x2000000 +#define SECTION_MACH_DEP 0x8000000 /* subsequent bits reserved for target */ I can bump SECTION_MACH_DEP even more to reserve more bits. -Sri.
