veneer to perform the state change.
This option is on by default. It has no effect if the target architecture does not
--no_blx_thumb_armprevents the possible issue with using a
BLX(immediate) instruction on an ARM1176JZ-S or ARM1176JZF-S. See the ARM1176JZ-S™ and ARM1176JZF-S™ Programmers Advice Notice Use of BLX (immediate) for more details.
