Return a raw pointer that uniquely identifies this attribute list.

Return the arguments to the instruction.

Return the raw optional flags value contained in this value. This should only be used when testing two Values for equivalence.

Return a reciprocal estimate value for the input operand. \p Enabled is a ReciprocalEstimate enum with value either 'Unspecified' or 'Enabled' as set

Returns the record name.

getReg - Returns the register number.

Accessors.

getRegAllocationHint - Return the register allocation hint for the specified virtual register. If there are many hints, this returns the one with the

Return the assembly name for \p Reg.

If the information for the register banks is available, return it. Otherwise return nullptr.

Return the register bank of \p Reg, or null if Reg has not been assigned a register bank or has been assigned a register class. \note It is possible t

Returns the register class associated with the enumeration value. See class MCOperandInfo.

Return the register class that should be used for the specified value type.

Returns the name of the register class.

Return the register class of \p Reg, or null if Reg has not been assigned a register class yet. \note A null register class can only happen when thes

getRegLiveOut - Returns a bit mask of live-out registers.

Returns an array of register mask pointers corresponding to getRegMaskSlots().

Returns an array of mask pointers corresponding to getRegMaskSlotsInBlock(MBBNum).

Returns number of elements needed for a regmask array.

Returns a sorted array of slot indices of all instructions with register mask operands.

Returns a sorted array of slot indices of all instructions with register mask operands in the basic block numbered \p MBBNum.

Return the register pressure "high water mark" for the specific register class. The scheduler is in high register pressure mode (for the specific regi

Get the register unit limit for the given pressure set index. RegisterClassInfo adjusts this limit for reserved registers.

Return a heuristic for the machine scheduler to compare the profitability of increasing one register pressure set versus another. The scheduler will

Target-dependent implementation of getRegSequenceInputs. \returns true if it is possible to build the equivalent REG_SEQUENCE inputs with the pair \p

Return the size in bits of a register from class RC.

Returns the register use/def slot in the current instruction for a normal or early-clobber def.

Get all register state flags from machine operand \p RegOp.

Return the specified register in the class.

Return the register ID of the name passed in. Used by named register global variables extension. There is no target-independent behaviour so the defau

Return the register cost table index. This implementation is sufficient for most architectures and can be overriden by targets in case there are multi

Get a list of cost values for all registers that correspond to the index returned by RegisterCostTableIndex.

Return the type of registers that this ValueType will eventually require.
