Also outstanding is that the return value setup for beginTransaction

.Lrestart:

This must be

    (set (reg eax) (call _ITM_beginTransaction))
.Lrestart:
    (set (reg psuedo) (reg eax))
    // rest of tm block

lest the register allocator do the wrong thing.

Yep good point. It means moving the insn from one BB to the next BB but 
I have no idea how to do it and where it should be done.

Thanks.
