llvm dev - Jul 2009 - [LLVMdev] LLVMContext: Who Creates It?

Dear Owen,

Are passes supposed to grab the LLVMContext from the
Module/Function/BasicBlock passed into their
runOn<Module/Function/BasicBlock> method, or is the PassManager supposed
to set the pass's Context member variable automatically?

I thought it was the latter, but after an SVN update of LLVM, my passes
have a NULL Context, and the LLVM code looks like the passes are all
setting their Context member variable explicitly.

Dear John,

I think you must call (YourPassManager)->doInitialization() to set the 
LLVMContext object.

I'm instantiating a regular PassManager object in my command-line tool. 
I don't believe the PassManager has a doInitialization() method, so I
don't think the above fixes my problem.
