...be nice to have support for some sort of a "addPreservedTransitive" method ... so that when a pass uses "setPreservesCFG", other passes such as dominator analysis will be automatically preserved too ... Sameer. -- Research Scholar, KReSIT, IIT Bombay http://www.it.iitb.ac.in/~sameerds/

...Simplify is not an analysis that the PassManager can update when some other pass changes the CFG. So the only way for my pass to ensure that the loops are simplified is to explicitly invoke LoopSimplify ... is that correct?

...allowed to retain state across functions. What does that imply for an Analysis pass derived from FunctionPass? Since all passes will act on one function at a time, the life of the analysis will be handled correctly, right? Sameer. -- Research Scholar, KReSIT, IIT Bombay http://www.it.iitb.ac.in/~sameerds/

...ince I am not a compiler guy myself, dunno if anyone actually ends up needing such a function. Anyway, the LoopSimplify code's been quite helpful as a quick intro to handling side-effects when modifying the CFG. Thanks!

...necessary. It's taking me a little effort to get used to that, but it should turn out to be a Good Thing(tm) after all. But the problem is that the presence and the significance of Scalar.h was not immediately obvious! Sameer. -- Research Scholar, KReSIT, IIT Bombay http://www.it.iitb.ac.in/~sameerds/

In LLVM 1.5, the function isLoopHeader fails to check for a null pointer after calling getLoopFor. Dunno if this is fixed in CVS, but attaching a patch anyway ...
