llvm dev - Oct 2012 - [LLVMdev] Error when trying to chain two llvm transform passes

Hi,

I am trying to chain two transform passes.

** The first pass is a function pass which requires the 'memory dependence
pass' .


** The second pass is a function pass which requires the first pass above.

The passes run fine when executed alone.


I get the following error when I try to run my second pass with the following
code added

>           AU.addRequired<First_Pass>();
>           
>       }

Assertion failed: (PI && "Expected required passes to be
initialized"), function schedulePass, file PassManager.cpp, line 597.


I register the passes using RegisterPass function call. What else should I be
doing?


I appreciate your help!!


regards,
Ashwin

Initializing them.  Are you using INITIALIZE_PASS_DEPENDENCY, 
INITIALIZE_AG_DEPENDENCY, etc?

No. I am not sure how they work . I am trying to use the INITIALIZE_PASS macro.
I get the following error


error: definition or redeclaration of 'initializeMyPassNamePass' not in
a namespace enclosing 'llvm'



should i add the passname to a header file ? if so where? 


Thank you!!
