llvm::M68kII Namespace Reference

This namespace holds all of the target specific flags that instruction info tracks. More...

Enumerations
enum	TOF {   MO_NO_FLAG , MO_ABSOLUTE_ADDRESS , MO_PC_RELATIVE_ADDRESS , MO_GOT ,   MO_GOTOFF , MO_GOTPCREL , MO_PLT }
	Target Operand Flag enum. More...

Functions
static bool	isGlobalStubReference (unsigned char TargetFlag)
	Return true if the specified TargetFlag operand is a reference to a stub for a global, not the global itself.
static bool	isDirectGlobalReference (unsigned char Flag)
	Return True if the specified GlobalValue is a direct reference for a symbol.
static bool	isGlobalRelativeToPICBase (unsigned char TargetFlag)
	Return true if the specified global value reference is relative to a 32-bit PIC base (M68kISD::GLOBAL_BASE_REG).
static bool	isPCRelGlobalReference (unsigned char Flag)
	Return True if the specified GlobalValue requires PC addressing mode.
static bool	isPCRelBlockReference (unsigned char Flag)
	Return True if the Block is referenced using PC.
static bool	isAddressRegister (unsigned RegNo)
static bool	hasMultiMIOperands (unsigned Op, unsigned LogicalOpIdx)
static unsigned	getMaskedSpillRegister (unsigned order)

Detailed Description

This namespace holds all of the target specific flags that instruction info tracks.

Enumeration Type Documentation

TOF

enum llvm::M68kII::TOF

Target Operand Flag enum.

Enumerator
MO_NO_FLAG
MO_ABSOLUTE_ADDRESS	On a symbol operand this indicates that the immediate is the absolute address of the symbol.
MO_PC_RELATIVE_ADDRESS	On a symbol operand this indicates that the immediate is the pc-relative address of the symbol.
MO_GOT	On a symbol operand this indicates that the immediate is the offset to the GOT entry for the symbol name from the base of the GOT. name@GOT
MO_GOTOFF	On a symbol operand this indicates that the immediate is the offset to the location of the symbol name from the base of the GOT. name@GOTOFF
MO_GOTPCREL	On a symbol operand this indicates that the immediate is offset to the GOT entry for the symbol name from the current code location. name@GOTPCREL
MO_PLT	On a symbol operand this indicates that the immediate is offset to the PLT entry of symbol name from the current code location. name@PLT
