Member Data Documentation

◆ Allowed

DenseSet<const char *>* llvm::AttributorConfig::Allowed = nullptr

If not null, a set limiting the attribute opportunities.

Definition at line 1252 of file Attributor.h.

Referenced by llvm::Attributor::getOrCreateAAFor().

◆ CGUpdater

CallGraphUpdater& llvm::AttributorConfig::CGUpdater

Helper to update an underlying call graph and to delete functions.

Definition at line 1249 of file Attributor.h.

Referenced by llvm::Attributor::removeCallSite().

◆ DefaultInitializeLiveInternals

bool llvm::AttributorConfig::DefaultInitializeLiveInternals = true

Flag to determine if we want to initialize all default AAs for an internal function marked live.

TODO: This should probably be a callback, or maybe identifyDefaultAbstractAttributes should be virtual, something to allow customizable lazy initialization for internal functions.

Definition at line 1246 of file Attributor.h.

Referenced by llvm::Attributor::markLiveInternalFunction(), llvm::OpenMPOptPass::run(), and llvm::OpenMPOptCGSCCPass::run().

◆ DeleteFns

bool llvm::AttributorConfig::DeleteFns = true

Flag to determine if we can delete functions or keep dead ones around.

Definition at line 1236 of file Attributor.h.

Referenced by llvm::Attributor::deleteAfterManifest().

◆ IsModulePass

bool llvm::AttributorConfig::IsModulePass = true

Is the user of the Attributor a module pass or not.

This determines what IR we can look at and modify. If it is a module pass we might deduce facts outside the initial function set and modify functions outside that set, but only as part of the optimization of the functions in the initial function set. For CGSCC passes we can look at the IR of the module slice but never run any deduction, or perform any modification, outside the initial function set (which we assume is the SCC).

◆ MaxFixpointIterations

Optional<unsigned> llvm::AttributorConfig::MaxFixpointIterations = None

Maximum number of iterations to run until fixpoint.

Definition at line 1255 of file Attributor.h.

◆ OREGetter

OptimizationRemarkGetter llvm::AttributorConfig::OREGetter = nullptr

Definition at line 1261 of file Attributor.h.

Referenced by llvm::Attributor::emitRemark(), llvm::OpenMPOptPass::run(), and llvm::OpenMPOptCGSCCPass::run().

◆ PassName

const char* llvm::AttributorConfig::PassName = nullptr

}

The name of the pass running the attributor, used to emit remarks.

Definition at line 1265 of file Attributor.h.

Referenced by llvm::Attributor::emitRemark(), llvm::OpenMPOptPass::run(), and llvm::OpenMPOptCGSCCPass::run().

◆ RewriteSignatures

bool llvm::AttributorConfig::RewriteSignatures = true

Flag to determine if we rewrite function signatures.

Definition at line 1239 of file Attributor.h.

Referenced by llvm::Attributor::isValidFunctionSignatureRewrite(), llvm::OpenMPOptPass::run(), and llvm::OpenMPOptCGSCCPass::run().
