class RequiredArgs

Declaration

class RequiredArgs { /* full declaration omitted */ };

Description

A class for recording the number of arguments that a function signature requires.

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:480

Member Variables

private unsigned int NumRequired

The number of required arguments, or ~0 if the signature does not permit optional arguments.

Methods

¶RequiredArgs(
    clang::CodeGen::RequiredArgs::All_t _)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:487

Parameters

clang::CodeGen::RequiredArgs::All_t _

¶RequiredArgs(unsigned int n)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:488

Parameters

unsigned int n

¶bool allowsOptionalArgs() const

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:524

¶static clang::CodeGen::RequiredArgs forPrototype(
    const clang::FunctionProtoType* prototype)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:516

Parameters

const clang::FunctionProtoType* prototype

¶static clang::CodeGen::RequiredArgs forPrototype(
    CanQual<clang::FunctionProtoType> prototype)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:520

Parameters

CanQual<clang::FunctionProtoType> prototype

¶static clang::CodeGen::RequiredArgs
forPrototypePlus(
    const clang::FunctionProtoType* prototype,
    unsigned int additional)

Description

Compute the arguments required by the given formal prototype, given that there may be some additional, non-formal arguments in play. If FD is not null, this will consider pass_object_size params in FD.

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:497

Parameters

const clang::FunctionProtoType* prototype

unsigned int additional

¶static clang::CodeGen::RequiredArgs
forPrototypePlus(
    CanQual<clang::FunctionProtoType> prototype,
    unsigned int additional)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:511

Parameters

CanQual<clang::FunctionProtoType> prototype

unsigned int additional

¶static clang::CodeGen::RequiredArgs
getFromOpaqueData(unsigned int value)

Declared at: clang/include/clang/CodeGen/CGFunctionInfo.h:531

Parameters

unsigned int value

¶unsigned int getNumRequiredArgs() const
