I wrote a pass(that is to be loaded by opt) that I would like to use
in conjunction with MemoryDependenceAnalysis. I have tried using by
including its header and adding this to my pass:
virtual void getAnalysisUsage(AnalysisUsage &AU) const {
errs() << "addRequired called\n";
AU.addRequired<MemoryDependenceAnalysis>();
}
And in my runOnFunction() method I have:
MD = &getAnalysis<MemoryDependenceAnalysis>();
The results in:
addRequired called
Assertion failed: (ResultPass && "getAnalysis*() called on
an
analysis that was not " "'required' by pass!"), function
getAnalysisID
I do not know why. I noticed the DeadStoreElimination pass also uses
this, but it does not use RegisterPass (like mine and the docs show).
Instead it has lines like:
INITIALIZE_PASS_DEPENDENCY(MemoryDependenceAnalysis)
This gives me:
error: C++ requires a type specifier for all declarations
What is the correct way todo this?
My pass(that I want to use MemoryDependenceAnalysis) is a ModulePass.
When I changed my assignment to:
MD = &getAnalysis<MemoryDependenceAnalysis>(F);
It fixed my initial problem but left me with:
Assertion failed: (ResultPass && "Unable to find requested
analysis info"), function getAnalysisID
