Detailed Description
This pass is required by interprocedural register allocation.
It forces codegen to follow bottom up order on call graph.

getAnalysisUsage - For this class, we declare that we require and preserve the call graph.
For this class, we declare that we require and preserve the call graph.
If the derived class implements this method, it should always explicitly call the implementation here.
Reimplemented from llvm::CallGraphSCCPass.

◆ runOnSCC()
|
inlineoverridevirtual |
runOnSCC - This method should be implemented by the subclass to perform whatever action is necessary for the specified SCC.
Note that non-recursive (or only self-recursive) functions will have an SCC size of 1, where recursive portions of the call graph will have SCC size > 1.
SCC passes that add or delete functions to the SCC are required to update the SCC list, otherwise stale pointers may be dereferenced.
Implements llvm::CallGraphSCCPass.
