[PATCH] D29283: [ARM] Avoid using ARM instructions in Thumb mode

Hi Renato,

Yes, I will look into the v7VE issue; however, I'm not sure how using an InstAlias would be possible since the operation of SWP and LDREX/STREX pair seems different to my understanding. The STREX returns a store success flag while SWP can atomically swap the value between a register and a memory location. Am I misunderstanding the use of these instructions?

Cheers,
Sam
