Hi, I will soon be committing a change to MachineFrameInfo::CreateStackObject that removes the "bool MayNeedSP" parameter. This API change is part of larger patch that re-works stack layout passes to use analysis from the StackProtector pass to layout StackProtected objects (http://llvm-reviews.chandlerc.com/D2158). Out of tree targets will need to update their usage accordingly. The most likely sce...

...he existing code to allow finer granularity and distinction between different SSP-triggering objects. - Some minor refactoring desired. For example, in CodeGen/SelectionDAG/FunctionLoweringInfo.cpp, there are checks for determining if an object would trigger a stack protectr (MayNeedSP). These checks are inconsistent with the checks in StackProtector. Both of these spots should use a common (i.e., same) check. 6) Updating/adding documentation. Note that the appropriate regression tests (updating existing tests and adding new ones) will be included with...
