Methods

¶void AddStringLiteralDebugInfo(
    llvm::GlobalVariable* GV,
    const clang::StringLiteral* S)

Description

DebugInfo isn't attached to string literals by default. While certain aspects of debuginfo aren't useful for string literals (like a name), it's nice to be able to symbolize the line and column information. This is especially useful for sanitizers, as it allows symbolization of heap-buffer-overflows on constant strings.

Declared at: clang/lib/CodeGen/CGDebugInfo.h:541

Parameters

llvm::GlobalVariable* GV

const clang::StringLiteral* S

¶void AppendAddressSpaceXDeref(
    unsigned int AddressSpace,
    SmallVectorImpl<uint64_t>& Expr) const

Description

If target-specific LLVM \p AddressSpace directly maps to target-specific DWARF address space, appends extended dereferencing mechanism to complex expression \p Expr. Otherwise, does nothing. Extended dereferencing mechanism is has the following format: DW_OP_constu <DWARF Address Space> DW_OP_swap DW_OP_xderef

Declared at: clang/lib/CodeGen/CGDebugInfo.h:361

Parameters

unsigned int AddressSpace

SmallVectorImpl<uint64_t>& Expr

¶CGDebugInfo(clang::CodeGen::CodeGenModule& CGM)

Declared at: clang/lib/CodeGen/CGDebugInfo.h:381

Parameters

¶llvm::DIGlobalVariableExpression*
CollectAnonRecordDecls(
    const clang::RecordDecl* RD,
    llvm::DIFile* Unit,
    unsigned int LineNo,
    llvm::StringRef LinkageName,
    llvm::GlobalVariable* Var,
    llvm::DIScope* DContext)

Description

Return a global variable that represents one of the collection of global variables created for an anonmyous union. Recursively collect all of the member fields of a global anonymous decl and create static variables for them. The first time this is called it needs to be on a union and then from there we can have additional unnamed fields.

Declared at: clang/lib/CodeGen/CGDebugInfo.h:722
