This problem was reported to me by a friend who has an LLVM port that is not put back to open source. Essentially, there is an intrinsic call _lr which is a load register. so then user code has something like: start_time = _lr(TIMER_REGISTER) ..... some_code_to_time .... end_time = _lr(TIMER_REGISTER) So what happens is that LLVM moves the code as follows: start_time = _lr(TIMER_REGISTER) end_time = _lr(TIMER_REGISTER) ..... some_code_to_time ...... How would this intrinsic be implemented properly in llvm so this cannot happen? TIA. Reed
