Detailed Description
This class contains all of the helper code which is used to perform the inlining operations that do not depend on the policy.
It contains the core bottom-up inlining infrastructure that specific inliner passes use.

Member Function Documentation
◆ doFinalization()
Remove now-dead linkonce functions at the end of processing to avoid breaking the SCC traversal.
Reimplemented from llvm::CallGraphSCCPass.
Definition at line 486 of file Inliner.cpp.
References llvm::ImportedFunctionsInliningStatistics::dump(), ImportedFunctionsStats, llvm::InlinerFunctionImportStats, llvm::No, removeDeadFunctions(), and llvm::Verbose.
◆ doInitialization()
doInitialization - This method is called before the SCC's of the program has been processed, allowing the pass to do initialization as necessary.
Reimplemented from llvm::CallGraphSCCPass.
Definition at line 219 of file Inliner.cpp.
References llvm::CallGraph::getModule(), ImportedFunctionsStats, llvm::InlinerFunctionImportStats, llvm::No, and llvm::ImportedFunctionsInliningStatistics::setModuleInfo().
◆ getAnalysisUsage()
|
overridevirtual |
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.
Definition at line 162 of file Inliner.cpp.
References llvm::AnalysisUsage::addRequired(), llvm::getAAResultsAnalysisUsage(), and llvm::CallGraphSCCPass::getAnalysisUsage().
◆ getInlineCost()
|
pure virtual |
This method must be implemented by the subclass to determine the cost of inlining the specified call site.
If the cost returned is greater than the current inline threshold, the call site is not inlined.
Referenced by inlineCalls().
◆ inlineCalls()
| bool LegacyInlinerBase::inlineCalls | ( | CallGraphSCC & | SCC | ) |
This function performs the main work of the pass.
The default of Inlinter::runOnSCC() calls skipSCC() before calling this method, but derived classes which cannot be skipped can override that method and call this function unconditionally.
Definition at line 468 of file Inliner.cpp.
References ACT, F, llvm::AssumptionCacheTracker::getAssumptionCache(), getInlineCost(), GetTLI, ImportedFunctionsStats, inlineCallsImpl(), and PSI.
Referenced by runOnSCC().
◆ removeDeadFunctions()
Remove dead functions.
Remove dead functions that are not included in DNR (Do Not Remove) list.
This also includes a hack in the form of the 'AlwaysInlineOnly' flag which restricts it to deleting functions with an 'AlwaysInline' attribute. This is useful for the InlineAlways pass that only wants to deal with that subset of the functions.

◆ runOnSCC()
|
overridevirtual |
Main run interface method, this implements the interface required by the Pass class.
Implements llvm::CallGraphSCCPass.
