AlwaysUninit ?

:

Forward-declares and imports various common LLVM datatypes that clang wants to use unqualified.

AnalysisDeclContext contains the context data for the function, method or block under analysis.

Represents a source-level, intra-procedural CFG that represents the control-flow of a Stmt.

DeclContext - This is used only as base class of specific decl types that can act as declaration cont...

This represents one expression.

Stmt - This represents one statement.

A use of a variable, which might be uninitialized.

const Expr * getUser() const

Get the expression containing the uninitialized use.

UninitUse(const Expr *User, bool AlwaysUninit)

SmallVectorImpl< Branch >::const_iterator branch_iterator

bool branch_empty() const

branch_iterator branch_end() const

void setUninitAfterCall()

void addUninitBranch(Branch B)

void setUninitAfterDecl()

branch_iterator branch_begin() const

Branches which inevitably result in the variable being used uninitialized.

Kind

The kind of uninitialized use.

@ Always

The use is always uninitialized.

@ AfterDecl

The use is uninitialized the first time it is reached after we reach the variable's declaration.

@ Maybe

The use might be uninitialized.

@ AfterCall

The use is uninitialized the first time it is reached after the function is called.

@ Sometimes

The use is uninitialized whenever a certain branch is taken.

Kind getKind() const

Get the kind of uninitialized use.

UninitVariablesHandler()=default

virtual void handleUseOfUninitVariable(const VarDecl *vd, const UninitUse &use)

Called when the uninitialized variable is used at the given expression.

virtual void handleSelfInit(const VarDecl *vd)

Called when the uninitialized variable analysis detects the idiom 'int x = x'.

virtual ~UninitVariablesHandler()

virtual void handleConstRefUseOfUninitVariable(const VarDecl *vd, const UninitUse &use)

Called when the uninitialized variable is used as const refernce argument.

Represents a variable declaration or definition.

The JSON file list parser is used to communicate input to InstallAPI.

void runUninitializedVariablesAnalysis(const DeclContext &dc, const CFG &cfg, AnalysisDeclContext &ac, UninitVariablesHandler &handler, UninitVariablesAnalysisStats &stats)
