|    How to back propagate basic block probab    |
|    04 Apr 10 08:45:56    |
      From: drtodd13@comcast.net              I'm writing a compiler and have a situation where I know a priori that       certain function names will only be called in the "slow path." When I       see one of these names, I'd like to set the probability of that basic       block to something low and then propagate the consequences of that       information back up the call graph. (For example, if there is only       one predecessor of a basic block containing a slow path call then that       predecessor should also be slow path.) Does anybody have any thoughts       on how to combine this back propagation with the natural downward       propagation of basic block probabilities.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
