static bool finalizeLinkage(Module &M)

Module.h This file contains the declarations for the Module class.

#define INITIALIZE_PASS_END(passName, arg, name, cfg, analysis)

#define INITIALIZE_PASS_BEGIN(passName, arg, name, cfg, analysis)

A container for analyses that lazily runs them and caches their results.

bool runOnModule(Module &M) override

runOnModule - Virtual method overriden by subclasses to process the module being operated on.

PreservedAnalyses run(Module &M, ModuleAnalysisManager &)

@ InternalLinkage

Rename collisions when linking (static functions).

@ ExternalLinkage

Externally visible function.

ModulePass class - This class is used to implement unstructured interprocedural optimizations and ana...

A Module instance is used to store all the information related to an LLVM module.

A set of analyses that are preserved following a run of a transformation pass.

static PreservedAnalyses none()

Convenience factory function for the empty preserved set.

static PreservedAnalyses all()

Construct a special preserved set that preserves all passes.

std::pair< iterator, bool > insert(PtrType Ptr)

Inserts Ptr if and only if there is no element in the container equal to Ptr.

SmallPtrSet - This class implements a set which is optimized for holding SmallSize or less elements.

This is an optimization pass for GlobalISel generic memory operations.

ModulePass * createDXILFinalizeLinkageLegacyPass()

Pass to finalize linkage of functions.
