Classes
struct	llvm::PrintedExpr
	A user-facing string representation of a DWARF expression. More...

Namespaces
namespace	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Typedefs
typedef DWARFExpression::Operation	llvm::Op
typedef Op::Description	llvm::Desc

Functions
static bool	llvm::decodeVirtualRegisterName (uint64_t DwarfRegNum, SmallString< 8 > &Out)
	Some backends (e.g.
static std::string	llvm::resolveRegName (uint64_t DwarfRegNum, bool IsEH, const std::function< StringRef(uint64_t, bool)> &GetNameForDWARFReg)
	Resolves a DWARF register number to a display name: first via GetNameForDWARFReg (MC register names), otherwise try decoding ASCII-encoded virtual register names (NVPTX-specific).
static void	llvm::prettyPrintBaseTypeRef (DWARFUnit *U, raw_ostream &OS, DIDumpOptions DumpOpts, ArrayRef< uint64_t > Operands, unsigned Operand)
static bool	llvm::printOp (const DWARFExpression::Operation *Op, raw_ostream &OS, DIDumpOptions DumpOpts, const DWARFExpression *Expr, DWARFUnit *U)
LLVM_ABI void	llvm::printDwarfExpression (const DWARFExpression *E, raw_ostream &OS, DIDumpOptions DumpOpts, DWARFUnit *U, bool IsEH=false)
	Print a Dwarf expression/.
static bool	llvm::printCompactDWARFExpr (raw_ostream &OS, DWARFExpression::iterator I, const DWARFExpression::iterator E, std::function< StringRef(uint64_t RegNum, bool IsEH)> GetNameForDWARFReg=nullptr)
LLVM_ABI bool	llvm::printDwarfExpressionCompact (const DWARFExpression *E, raw_ostream &OS, std::function< StringRef(uint64_t RegNum, bool IsEH)> GetNameForDWARFReg=nullptr)
	Print the expression in a format intended to be compact and useful to a user, but not perfectly unambiguous, or capable of representing every valid DWARF expression.
LLVM_ABI bool	llvm::prettyPrintRegisterOp (DWARFUnit *U, raw_ostream &OS, DIDumpOptions DumpOpts, uint8_t Opcode, ArrayRef< uint64_t > Operands)
	Pretty print a register opcode and operands.
