The ARM Linker can work around the possible issue on an ARM1176JZ-S or ARM1176JZF-S, where a BLX (immediate) instruction might corrupt the instruction stream. If your software is likely to run on an ARM1176JZ-S or ARM1176JZF-S, see the ARM1176JZ-S™ and ARM1176JZF-S™ Programmers Advice Notice Use of BLX (immediate) for more details.

If you decide to apply the workaround, you must use the linker option --no_blx_thumb_arm.
