[LLVMdev] about AnalysisUsage

[Sameer D. Sahasrabuddhe]

Just noticed that quite a few passes like LoopSimplify are implemented
in a single .cpp file ... this makes it impossible to specify
LoopSimplify using the "addRequired" method. Was there any particular
reason to do it this way? I wouldn't mind doing the splitting myself,
though I am not using the CVS versions right now.

Also, it would 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.
