Detailed Description

Helper struct used in the communication between an abstract attribute (AA) that wants to change the signature of a function and the Attributor which applies the changes.

The struct is partially initialized with the information from the AA (see the constructor). All other members are provided by the Attributor prior to invoking any callbacks.

Member Typedef Documentation

ACSRepairCBTy

using llvm::Attributor::ArgumentReplacementInfo::ACSRepairCBTy = std::function<void(const ArgumentReplacementInfo &, AbstractCallSite, SmallVectorImpl<Value *> &)>

Abstract call site (ACS) repair callback type.

The abstract call site repair callback is invoked once on every abstract call site of the replaced function (

See also

ReplacedFn). The callback needs to provide the operands for the call to the new replacement function. The number and type of the operands appended to the provided vector (second argument) is defined by the number and types determined through the replacement type vector (

ReplacementTypes). The first argument is the ArgumentReplacementInfo object registered with the Attributor through the registerFunctionSignatureRewrite call.

CalleeRepairCBTy

using llvm::Attributor::ArgumentReplacementInfo::CalleeRepairCBTy = std::function<void( const ArgumentReplacementInfo &, Function &, Function::arg_iterator)>

Callee repair callback type.

The function repair callback is invoked once to rewire the replacement arguments in the body of the new function. The argument replacement info is passed, as build from the registerFunctionSignatureRewrite call, as well as the replacement function and an iteratore to the first replacement argument.
