Name Lookup
These routines provide name lookup that is used during semantic analysis to resolve the various kinds of names (identifiers, overloaded operator names, constructor names, etc.) into zero or more declarations within a particular scope. The major entry points are LookupName, which performs unqualified name lookup, and LookupQualifiedName, which performs qualified name lookup. All name lookup is performed based on some specific criteria, which specify what names will be visible to name lookup and how far name lookup should work. These criteria are important both for capturing language semantics (certain lookups will ignore certain names, for example) and for performance, since name lookup is often a bottleneck in the compilation of C++. Name lookup criteria is specified via the LookupCriteria enumeration. The results of name lookup can vary based on the kind of name lookup performed, the current language, and the translation unit. In C, for example, name lookup will either return nothing (no entity found) or a single declaration. In C++, name lookup can additionally refer to a set of overloaded functions or result in an ambiguity. All of the possible results of name lookup are captured by the LookupResult class, which provides the ability to distinguish among them. Implementations are in SemaLookup.cpp

AvailabilityPriority

enum clang::Sema::AvailabilityPriority : int

Describes the kind of priority given to an availability attribute.

The sum of priorities deteremines the final priority of the attribute. The final priority determines how the attribute will be merged. An attribute with a lower priority will always remove higher priority attributes for the specified platform when it is being applied. An attribute with a higher priority will not be applied if the declaration already has an availability attribute with a lower priority for the specified platform. The final prirority values are not expected to match the values in this enumeration, but instead should be treated as a plain integer value. This enumeration just names the priority weights that are used to calculate that final vaue.

Enumerator
AP_Explicit	The availability attribute was specified explicitly next to the declaration.
AP_PragmaClangAttribute	The availability attribute was applied using '#pragma clang attribute'.
AP_InferredFromOtherPlatform	The availability attribute for a specific platform was inferred from an availability attribute for another platform.

ExpressionEvaluationContext

enum class clang::Sema::ExpressionEvaluationContext

strong

Describes how the expressions currently being parsed are evaluated at run-time, if at all.

Enumerator
Unevaluated	The current expression and its subexpressions occur within an unevaluated operand (C++11 [expr]p7), such as the subexpression of sizeof, where the type of the expression may be significant but no code will be generated to evaluate the value of the expression at run time.
UnevaluatedList	The current expression occurs within a braced-init-list within an unevaluated operand. This is mostly like a regular unevaluated context, except that we still instantiate constexpr functions that are referenced here so that we can perform narrowing checks correctly.
DiscardedStatement	The current expression occurs within a discarded statement. This behaves largely similarly to an unevaluated operand in preventing definitions from being required, but not in other ways.
UnevaluatedAbstract	The current expression occurs within an unevaluated operand that unconditionally permits abstract references to fields, such as a SIZE operator in MS-style inline assembly.
ConstantEvaluated	The current context is "potentially evaluated" in C++11 terms, but the expression is evaluated at compile-time (like the values of cases in a switch statement).
ImmediateFunctionContext	In addition of being constant evaluated, the current expression occurs in an immediate function context - either a consteval function or a consteval if statement.
PotentiallyEvaluated	The current expression is potentially evaluated at run time, which means that code may be generated to evaluate the value of the expression at run time.
PotentiallyEvaluatedIfUsed	The current expression is potentially evaluated, but any declarations referenced inside that expression are only used if in fact the current expression is used. This value is used when parsing default function arguments, for which we would like to provide diagnostics (e.g., passing non-POD arguments through varargs) but do not want to mark declarations as "referenced" until the default argument is used.

Enumerator
LOLR_Error	The lookup resulted in an error.
LOLR_ErrorNoDiagnostic	The lookup found no match but no diagnostic was issued.
LOLR_Cooked	The lookup found a single 'cooked' literal operator, which expects a normal literal to be built and passed to it.
LOLR_Raw	The lookup found a single 'raw' literal operator, which expects a string literal containing the spelling of the literal token.
LOLR_Template	The lookup found an overload set of literal operator templates, which expect the characters of the spelling of the literal token to be passed as a non-type template argument pack.
LOLR_StringTemplatePack	The lookup found an overload set of literal operator templates, which expect the character type and characters of the spelling of the string literal token to be passed as template arguments.

LookupNameKind

enum clang::Sema::LookupNameKind

Describes the kind of name lookup to perform.

Enumerator
LookupOrdinaryName	Ordinary name lookup, which finds ordinary names (functions, variables, typedefs, etc.) in C and most kinds of names (functions, variables, members, types, etc.) in C++.
LookupTagName	Tag name lookup, which finds the names of enums, classes, structs, and unions.
LookupLabel	Label name lookup.
LookupMemberName	Member name lookup, which finds the names of class/struct/union members.
LookupOperatorName	Look up of an operator name (e.g., operator+) for use with operator overloading. This lookup is similar to ordinary name lookup, but will ignore any declarations that are class members.
LookupDestructorName	Look up a name following ~ in a destructor name. This is an ordinary lookup, but prefers tags to typedefs.
LookupNestedNameSpecifierName	Look up of a name that precedes the '::' scope resolution operator in C++. This lookup completely ignores operator, object, function, and enumerator names (C++ [basic.lookup.qual]p1).
LookupNamespaceName	Look up a namespace name within a C++ using directive or namespace alias definition, ignoring non-namespace names (C++ [basic.lookup.udir]p1).
LookupUsingDeclName	Look up all declarations in a scope with the given name, including resolved using declarations. This is appropriate for checking redeclarations for a using declaration.
LookupRedeclarationWithLinkage	Look up an ordinary name that is going to be redeclared as a name with linkage. This lookup ignores any declarations that are outside of the current scope unless they have linkage. See C99 6.2.2p4-5 and C++ [basic.link]p6.
LookupLocalFriendName	Look up a friend of a local class. This lookup does not look outside the innermost non-class scope. See C++11 [class.friend]p11.
LookupObjCProtocolName	Look up the name of an Objective-C protocol.
LookupObjCImplicitSelfParam	Look up implicit 'self' parameter of an objective-c method.
LookupOMPReductionName	Look up the name of an OpenMP user-defined reduction operation.
LookupOMPMapperName	Look up the name of an OpenMP user-defined mapper.
LookupAnyName	Look up any declaration with any name.

ActOnCXXNestedNameSpecifier() [2/2]

bool Sema::ActOnCXXNestedNameSpecifier	(	Scope *	S,
		NestedNameSpecInfo &	IdInfo,
		bool	EnteringContext,
		CXXScopeSpec &	SS,
		bool *	IsCorrectedToColon = nullptr,
		bool	OnlyNamespace = false )

The parser has parsed a nested-name-specifier 'identifier::'.

Parameters

S	The scope in which this nested-name-specifier occurs.
IdInfo	Parser information about an identifier in the nested-name-spec.
EnteringContext	Whether we're entering the context nominated by this nested-name-specifier.
SS	The nested-name-specifier, which is both an input parameter (the nested-name-specifier before this type) and an output parameter (containing the full nested-name-specifier, including this new type).
IsCorrectedToColon	If not null, suggestions to replace '::' -> ':' are allowed. The bool value pointed by this parameter is set to 'true' if the identifier is treated as if it was followed by ':', not '::'.
OnlyNamespace	If true, only considers namespaces in lookup.

Returns

true if an error occurred, false otherwise.

ActOnFriendTypeDecl()

Decl * Sema::ActOnFriendTypeDecl	(	Scope *	S,
		const DeclSpec &	DS,
		MultiTemplateParamsArg	TemplateParams,
		SourceLocation	EllipsisLoc )

Handle a friend type declaration.

This works in tandem with ActOnTag.

Notes on friend class templates:

We generally treat friend class declarations as if they were declaring a class. So, for example, the elaborated type specifier in a friend declaration is required to obey the restrictions of a class-head (i.e. no typedefs in the scope chain), template parameters are required to match up with simple template-ids, &c. However, unlike when declaring a template specialization, it's okay to refer to a template specialization without an empty template parameter declaration, e.g. friend class A<T>::B<unsigned>; We permit this as a special case; if there are any template parameters present at all, require proper matching, i.e. template <> template <class T> friend class A<int>::B;

FIXME: it'd be better to split this interface into two so we don't take a void *, but that's awkward because one of the operands is either a ParsedType or an Expr *, which doesn't lend itself to generic code very well.

ActOnStartDelayedCXXMethodDeclaration - We have completed parsing a top-level (non-nested) C++ class, and we are now parsing those parts of the given Method declaration that could not be parsed earlier (C++ [class.mem]p2), such as default arguments.

This action should enter the scope of the given Method declaration as if we had just parsed the qualified method name. However, it should not bring the parameters into scope; that will be performed by ActOnDelayedCXXMethodParameter.

ActOnStartLinkageSpecification - Parsed the beginning of a C++ linkage specification, including the language and (if present) the '{'.

ExternLoc is the location of the 'extern', Lang is the language string literal. LBraceLoc, if valid, provides the location of the '{' brace. Otherwise, this linkage specification does not have any braces.

• Otherwise, if the declaration

This is invoked when we see 'struct foo' or 'struct {'.

In the former case, Name will be non-null. In the later case, Name will be null. TagSpec indicates what kind of tag this is. TUK indicates whether this is a reference/declaration/definition of a tag.

Parameters

IsTypeSpecifier	true if this is a type-specifier (or trailing-type-specifier) other than one in an alias-declaration.
SkipBody	If non-null, will be set to indicate if the caller should skip the definition of this tag and treat it as if it were a declaration.

Create a new tag decl in C/ObjC. Since the ODR-like semantics for ObjC/C implemented asks for structural equivalence checking, the returned decl here is passed back to the parser, allowing the tag body to be parsed.

Form a template name from a name that is syntactically required to name a template, either due to use of the 'template' keyword or because a name in this syntactic context is assumed to name a template (C++ [temp.names]p2-4).

This action forms a template name given the name of the template and its optional scope specifier. This is used when the 'template' keyword is used or when the parsing context unambiguously treats a following '<' as introducing a template argument list. Note that this may produce a non-dependent template name if we can perform the lookup now and identify the named template.

For example, given "x.MetaFun::template apply", the scope specifier SS will be "MetaFun::", TemplateKWLoc contains the location of the "template" keyword, and "apply" is the Name.

Convert a parsed type into a parsed template argument.

This is mostly trivial, except that we may have parsed a C++17 deduced class template specialization type, in which case we should form a template template argument instead of a type template argument.

AddOverloadCandidate - Adds the given function to the set of candidate functions, using the given function call arguments.

If SuppressUserConversions, then don't allow user-defined conversions via constructors or conversion operators.

Parameters

PartialOverloading

true if we are performing "partial" overloading based on an incomplete set of function arguments. This feature is used by code completion.

FIXME: Currently, the semantics of linkage in clang is slightly different from the semantics in C++ spec. In C++ spec, only names have linkage. So that all entities of the same should share one linkage. But in clang, different entities of the same could have different linkage.

Don't remove inline functions with internal linkage from the overload set if they are declared in a GMF, in violation of C++ [basic.link]p17. However:

• Inline functions with internal linkage are a common pattern in headers to avoid ODR issues.
• The global module is meant to be a transition mechanism for C and C++ headers, and the current rules as written work against that goal.

BuildCXXNestedNameSpecifier()

bool Sema::BuildCXXNestedNameSpecifier	(	Scope *	S,

		bool	EnteringContext,
		CXXScopeSpec &	SS,
		NamedDecl *	ScopeLookupResult,
		bool	ErrorRecoveryLookup,
		bool *	IsCorrectedToColon = nullptr,
		bool	OnlyNamespace = false )

Build a new nested-name-specifier for "identifier::", as described by ActOnCXXNestedNameSpecifier.

Parameters

S	Scope in which the nested-name-specifier occurs.
IdInfo	Parser information about an identifier in the nested-name-spec.
EnteringContext	If true, enter the context specified by the nested-name-specifier.
SS	Optional nested name specifier preceding the identifier.
ScopeLookupResult	Provides the result of name lookup within the scope of the nested-name-specifier that was computed at template definition time.
ErrorRecoveryLookup	Specifies if the method is called to improve error recovery and what kind of recovery is performed.
IsCorrectedToColon	If not null, suggestion of replace '::' -> ':' are allowed. The bool value pointed by this parameter is set to 'true' if the identifier is treated as if it was followed by ':', not '::'.
OnlyNamespace	If true, only considers namespaces in lookup.

This routine differs only slightly from ActOnCXXNestedNameSpecifier, in that it contains an extra parameter ScopeLookupResult, which provides the result of name lookup within the scope of the nested-name-specifier that was computed at template definition time.

If ErrorRecoveryLookup is true, then this call is used to improve error recovery. This means that it should not emit diagnostics, it should just return true on failure. It also means it should only return a valid scope if it knows that the result is correct. It should not return in a dependent context, for example. Nor will it extend SS with the scope specifier.

If the given LookupResult is non-empty, it is assumed to describe a member which will be invoked. Otherwise, the function will be found via argument dependent lookup.

QualType Sema::BuildFunctionType	(	QualType	T,
		MutableArrayRef< QualType >	ParamTypes,

Build a function type.

This routine checks the function type according to C++ rules and under the assumption that the result type and parameter types have just been instantiated from a template. It therefore duplicates some of the behavior of GetTypeForDeclarator, but in a much simpler form that is only suitable for this narrow use case.

Parameters

T	The return type of the function.
ParamTypes	The parameter types of the function. This array will be modified to account for adjustments to the types of the function parameters.
Loc	The location of the entity whose type involves this function type or, if there is no such entity, the location of the type that will have function type.
Entity	The name of the entity that involves the function type, if known.
EPI	Extra information about the function type. Usually this will be taken from an existing function with the same prototype.

Returns

A suitable function type, if there are no errors. The unqualified type will always be a FunctionProtoType. Otherwise, returns a NULL type.

CheckAssignmentConstraints() [1/2]

Check assignment constraints and optionally prepare for a conversion of the RHS to the LHS type.

CheckAssignmentConstraints (C99 6.5.16) - This routine currently has code to accommodate several GCC extensions when type checking pointers.

The conversion is prepared for if ConvertRHS is true.

Here are some objectionable examples that GCC considers warnings:

int a, *pint; short *pshort; struct foo *pfoo;

pint = pshort; // warning: assignment from incompatible pointer type a = pint; // warning: assignment makes integer from pointer without a cast pint = a; // warning: assignment makes pointer from integer without a cast pint = pfoo; // warning: assignment from incompatible pointer type

As a result, the code for dealing with pointers is more complex than the C99 spec dictates.

Sets 'Kind' for any result kind except Incompatible.

Check if applying the specified attribute variant from the "counted by" family of attributes to FieldDecl FD is semantically valid.

If semantically invalid diagnostics will be emitted explaining the problems.

Parameters

FD	The FieldDecl to apply the attribute to
E	The count expression on the attribute
CountInBytes	If true the attribute is from the "sized_by" family of attributes. If the false the attribute is from "counted_by" family of attributes.
OrNull	If true the attribute is from the "_or_null" suffixed family of attributes. If false the attribute does not have the suffix.

Together CountInBytes and OrNull decide the attribute variant. E.g. CountInBytes and OrNull both being true indicates the counted_by_or_null attribute.

Returns

false iff semantically valid.

Make sure the value of 'this' is actually available in the current context, if it is a potentially evaluated context.

Parameters

Loc	The location at which the capture of 'this' occurs.
Explicit	Whether 'this' is explicitly captured in a lambda capture list.
FunctionScopeIndexToStopAt	If non-null, it points to the index of the FunctionScopeInfo stack beyond which we do not attempt to capture. This is useful when enclosing lambdas must speculatively capture 'this' that may or may not be used in certain specializations of a nested generic lambda (depending on whether the name resolves to a non-static member function or a static function).

Returns

returns 'true' if failed, 'false' if success.

whether this new function declaration is a member specialization (that replaces any definition provided by the previous declaration).

This sets NewFD->isInvalidDecl() to true if there was an error.

Returns

true if the function declaration is a redeclaration.

CheckFunctionTemplateSpecialization()

bool Sema::CheckFunctionTemplateSpecialization	(	FunctionDecl *	FD,

Perform semantic analysis for the given function template specialization.

This routine performs all of the semantic analysis required for an explicit function template specialization. On successful completion, the function declaration FD will become a function template specialization.

Parameters

FD	the function declaration, which will be updated to become a function template specialization.
ExplicitTemplateArgs	the explicitly-provided template arguments, if any. Note that this may be valid info even when 0 arguments are explicitly provided as in, e.g., void sort<>(char*, char*); as it anyway contains info on the angle brackets locations.
Previous	the set of declarations that may be specialized by this function specialization.
QualifiedFriend	whether this is a lookup for a qualified friend declaration with no explicit template argument list that might be befriending a function template specialization.

Parameters

Type	The type to which the nullability specifier will be added. On success, this type will be updated appropriately.
Nullability	The nullability specifier to add.
DiagLoc	The location to use for diagnostics.
AllowArrayTypes	Whether to accept nullability specifiers on an array type (e.g., because it will decay to a pointer).
OverrideExisting	Whether to override an existing, locally-specified nullability specifier rather than complaining about the conflict.

CheckOverload()

OverloadKind Sema::CheckOverload	(	Scope *	S,
		FunctionDecl *	New,
		const LookupResult &	OldDecls,
		NamedDecl *&	OldDecl,
		bool	UseMemberUsingDeclRules )

Determine whether the given New declaration is an overload of the declarations in Old.

This routine returns OverloadKind::Match or OverloadKind::NonFunction if New and Old cannot be overloaded, e.g., if New has the same signature as some function in Old (C++ 1.3.10) or if the Old declarations aren't functions (or function templates) at all. When it does return OverloadKind::Match or OverloadKind::NonFunction, MatchedDecl will point to the decl that New cannot be overloaded with. This decl may be a UsingShadowDecl on top of the underlying declaration.

Example: Given the following input:

void f(int, float); // #1 void f(int, int); // #2 int f(int, int); // #3

When we process #1, there is no previous declaration of "f", so IsOverload will not be used.

When we process #2, Old contains only the FunctionDecl for #1. By comparing the parameter types, we see that #1 and #2 are overloaded (since they have different signatures), so this routine returns OverloadKind::Overload; MatchedDecl is unchanged.

When we process #3, Old is an overload set containing #1 and #2. We compare the signatures of #3 to #1 (they're overloaded, so we do nothing) and then #3 to #2. Since the signatures of #3 and #2 are identical (return types of functions are not part of the signature), IsOverload returns OverloadKind::Match and MatchedDecl will be set to point to the FunctionDecl for #2.

'NewIsUsingShadowDecl' indicates that 'New' is being introduced into a class by a using declaration. The rules for whether to hide shadow declarations ignore some properties which otherwise figure into a function template's signature.

Determine whether we could expand a pack expansion with the given set of parameter packs into separate arguments by repeatedly transforming the pattern.

Parameters

EllipsisLoc	The location of the ellipsis that identifies the pack expansion.
PatternRange	The source range that covers the entire pattern of the pack expansion.
Unexpanded	The set of unexpanded parameter packs within the pattern.
ShouldExpand	Will be set to true if the transformer should expand the corresponding pack expansions into separate arguments. When set, NumExpansions must also be set.
RetainExpansion	Whether the caller should add an unexpanded pack expansion after all of the expanded arguments. This is used when extending explicitly-specified template argument packs per C++0x [temp.arg.explicit]p9.
NumExpansions	The number of separate arguments that will be in the expanded form of the corresponding pack expansion. This is both an input and an output parameter, which can be set by the caller if the number of expansions is known a priori (e.g., due to a prior substitution) and will be set by the callee when the number of expansions is known. The callee must set this value when ShouldExpand is true; it may set this value in other cases.

Returns

true if an error occurred (e.g., because the parameter packs are to be instantiated with arguments of different lengths), false otherwise. If false, ShouldExpand (and possibly NumExpansions) must be set.

CheckTemplateArgumentList() [1/2]

bool Sema::CheckTemplateArgumentList	(	TemplateDecl *	Template,
		SourceLocation	TemplateLoc,
		TemplateArgumentListInfo &	TemplateArgs,
		const DefaultArguments &	DefaultArgs,
		bool	PartialTemplateArgs,
		CheckTemplateArgumentInfo &	CTAI,
		bool	UpdateArgsWithConversions = true,
		bool *	ConstraintsNotSatisfied = nullptr )

Check that the given template arguments can be provided to the given template, converting the arguments along the way.

Check that the given template argument list is well-formed for specializing the given template.

Parameters

Template	The template to which the template arguments are being provided.
TemplateLoc	The location of the template name in the source.
TemplateArgs	The list of template arguments. If the template is a template template parameter, this function may extend the set of template arguments to also include substituted, defaulted template arguments.
PartialTemplateArgs	True if the list of template arguments is intentionally partial, e.g., because we're checking just the initial set of template arguments.
Converted	Will receive the converted, canonicalized template arguments.
UpdateArgsWithConversions	If true, update TemplateArgs to contain the converted forms of the template arguments as written. Otherwise, TemplateArgs will not be modified.
ConstraintsNotSatisfied	If provided, and an error occurred, will receive true if the cause for the error is the associated constraints of the template not being satisfied by the template arguments.
DefaultArgs	any default arguments from template specialization deduction.

Returns

true if an error occurred, false otherwise.

CheckTemplateParameterList()

bool Sema::CheckTemplateParameterList	(	TemplateParameterList *	NewParams,
		TemplateParameterList *	OldParams,
		TemplateParamListContext	TPC,
		SkipBodyInfo *	SkipBody = nullptr )

Checks the validity of a template parameter list, possibly considering the template parameter list from a previous declaration.

If an "old" template parameter list is provided, it must be equivalent (per TemplateParameterListsAreEqual) to the "new" template parameter list.

Parameters

NewParams	Template parameter list for a new template declaration. This template parameter list will be updated with any default arguments that are carried through from the previous template parameter list.
OldParams	If provided, template parameter list from a previous declaration of the same template. Default template arguments will be merged from the old template parameter list to the new template parameter list.
TPC	Describes the context in which we are checking the given template parameter list.
SkipBody	If we might have already made a prior merged definition of this template visible, the corresponding body-skipping information. Default argument redefinition is not an error when skipping such a body, because (under the ODR) we can assume the default arguments are the same as the prior merged definition.

Returns

true if an error occurred, false otherwise.

Compute the DeclContext that is associated with the given scope specifier.

Parameters

SS	the C++ scope specifier as it appears in the source
EnteringContext	when true, we will be entering the context of this scope specifier, so we can retrieve the declaration context of a class template or class template partial specialization even if it is not the current instantiation.

Returns

the declaration context represented by the scope specifier SS, or NULL if the declaration context cannot be computed (e.g., because it is dependent and not the current instantiation).

computeNRVO()

void Sema::computeNRVO	(	Stmt *	Body,
		sema::FunctionScopeInfo *	Scope )

Given the set of return statements within a function body, compute the variables that are subject to the named return value optimization.

Each of the variables that is subject to the named return value optimization will be marked as NRVO variables in the AST, and any return statement that has a marked NRVO variable as its NRVO candidate can use the named return value optimization.

This function applies a very simplistic algorithm for NRVO: if every return statement in the scope of a variable has the same NRVO candidate, that candidate is an NRVO variable.

		bool	RecordFailure = true )

Try to "correct" a typo in the source code by finding visible declarations whose names are similar to the name that was present in the source code.

Parameters

TypoName	the DeclarationNameInfo structure that contains the name that was present in the source code along with its location.
LookupKind	the name-lookup criteria used to search for the name.
S	the scope in which name lookup occurs.
SS	the nested-name-specifier that precedes the name we're looking for, if present.
CCC	A CorrectionCandidateCallback object that provides further validation of typo correction candidates. It also provides flags for determining the set of keywords permitted.
MemberContext	if non-NULL, the context in which to look for a member access expression.
EnteringContext	whether we're entering the context described by the nested-name-specifier SS.
OPT	when non-NULL, the search for visible declarations will also walk the protocols in the qualified interfaces of OPT.

Returns

a TypoCorrection containing the corrected name if the typo along with information such as the NamedDecl where the corrected name was declared, and any additional NestedNameSpecifier needed to access it (C++ only). The TypoCorrection is empty if there is no correction.

Create a binary operation that may resolve to an overloaded operator.

Parameters

OpLoc	The location of the operator itself (e.g., '+').
Opc	The BinaryOperatorKind that describes this operator.
Fns	The set of non-member functions that will be considered by overload resolution. The caller needs to build this set based on the context using, e.g., LookupOverloadedOperatorName() and ArgumentDependentLookup(). This set should not contain any member functions; those will be added by CreateOverloadedBinOp().
LHS	Left-hand argument.
RHS	Right-hand argument.
PerformADL	Whether to consider operator candidates found by ADL.
AllowRewrittenCandidates	Whether to consider candidates found by C++20 operator rewrites.
DefaultedFn	If we are synthesizing a defaulted operator function, the function in question. Such a function is never a candidate in our overload resolution. This also enables synthesizing a three-way comparison from < and == as described in C++20 [class.spaceship]p1.

		ExprResult &	lhs,

Check the operands of ?

: under C++ semantics.

See C++ [expr.cond]. Note that LHS is never null, even for the GNU x ?: y extension. In this case, LHS == Cond. (But they're not aliases.)

This function also implements GCC's vector extension and the OpenCL/ext_vector_type extension for conditionals. The vector extensions permit the use of a?b:c where the type of a is that of a integer vector with the same number of elements and size as the vectors of b and c. If one of either b or c is a scalar it is implicitly converted to match the type of the vector. Otherwise the expression is ill-formed. If both b and c are scalars, then b and c are checked and converted to the type of a if possible.

The expressions are evaluated differently for GCC's and OpenCL's extensions. For the GCC extension, the ?: operator is evaluated as (a[0] != 0 ? b[0] : c[0], .. , a[n] != 0 ? b[n] : c[n]). For the OpenCL extensions, the ?: operator is evaluated as (most-significant-bit-set(a[0]) ? b[0] : c[0], .. , most-significant-bit-set(a[n]) ? b[n] : c[n]).

		bool	DependentDeduction = false,
		bool	IgnoreConstraints = false,
		TemplateSpecCandidateSet *	FailedTSC = nullptr )

Deduce the type for an auto type-specifier (C++11 [dcl.spec.auto]p6)

Note that this is done even if the initializer is dependent. (This is necessary to support partial ordering of templates using 'auto'.) A dependent type will be produced when deducing from a dependent type.

Parameters

Type	the type pattern using the auto type-specifier.
Init	the initializer for the variable whose type is to be deduced.
Result	if type deduction was successful, this will be set to the deduced type.
Info	the argument will be updated to provide additional information about template argument deduction.
DependentDeduction	Set if we should permit deduction in dependent cases. This is necessary for template partial ordering with 'auto' template parameters. The template parameter depth to be used should be specified in the 'Info' parameter.
IgnoreConstraints	Set if we should not fail if the deduced type does not satisfy the type-constraint in the auto type.

Perform template argument deduction from a function call (C++ [temp.deduct.call]).

Parameters

FunctionTemplate	the function template for which we are performing template argument deduction.
ExplicitTemplateArgs	the explicit template arguments provided for this call.
Args	the function call arguments
Specialization	if template argument deduction was successful, this will be set to the function template specialization produced by template argument deduction.
Info	the argument will be updated to provide additional information about template argument deduction.
CheckNonDependent	A callback to invoke to check conversions for non-dependent parameters, between deduction and substitution, per DR1391. If this returns true, substitution will be skipped and we return TemplateDeductionResult::NonDependentConversionFailure. The callback is passed the parameter types (after substituting explicit template arguments).

Returns

the result of template argument deduction.
