Enables the linker to use the BLX instruction
for Thumb to ARM state changes. If the linker cannot use BLX it
must use a Thumb to ARM interworking veneer to perform the state
change.
This option is on by default. It has no effect if the target
architecture does not support BLX.
Note
Using --no_blx_thumb_arm prevents 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.
