Arm Compiler armlink User Guide : --blx_arm_thumb, --no_blx_arm_thumb

--blx_arm_thumb, --no_blx_arm_thumb

Enables the linker to use the BLX instruction for A32 to T32 state changes.

Usage

If the linker cannot use BLX it must use an A32 to T32 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 or when linking for AArch64 state.
