[PATCH] disabled switching ARM modes in inline asm

[Renato Golin]

  Hi Greg,

  The two problems I mapped from our discussion were:
   1. The compiler must go back to its own state after inline assembly, and err if the user makes it hard.
   2. The compiler must detect changes in inline assembly, and record its own state, to be able to do so.

  Forbidding state change altogether is a first approach on correctness, and I'm fine with this patch as it is. For the future, do you plan on implementing a more fine grained approach?

I don't understand why you need this...
