Detailed Description

MachineOperand class - Representation of each machine instruction operand.

This class isn't a POD type because it has a private constructor, but its destructor must be trivial. Functions like MachineInstr::addOperand(), MachineRegisterInfo::moveOperands(), and MF::DeleteMachineInstr() depend on not having to call the MachineOperand destructor.

◆ CreateRegMask()

static MachineOperand llvm::MachineOperand::CreateRegMask ( const uint32_t * Mask )

inlinestatic

CreateRegMask - Creates a register mask operand referencing Mask.

The operand does not take ownership of the memory referenced by Mask, it must remain valid for the lifetime of the operand.

A RegMask operand represents a set of non-clobbered physical registers on an instruction that clobbers many registers, typically a call. The bit mask has a bit set for each physreg that is preserved by this instruction, as described in the documentation for TargetRegisterInfo::getCallPreservedMask().

Any physreg with a 0 bit in the mask is clobbered by the instruction.

◆ isRenamable()

bool MachineOperand::isRenamable ( ) const

isRenamable - Returns true if this register may be renamed, i.e.

it does not generate a value that is somehow read in a way that is not represented by the Machine IR (e.g. to meet an ABI or ISA requirement). This is only valid on physical register operands. Virtual registers are assumed to always be renamable regardless of the value of this field.

Operands that are renamable can freely be changed to any other register that is a member of the register class returned by MI->getRegClassConstraint().

isRenamable can return false for several different reasons:

ABI constraints (since liveness is not always precisely modeled). We conservatively handle these cases by setting all physical register operands that didn’t start out as virtual regs to not be renamable. Also any physical register operands created after register allocation or whose register is changed after register allocation will not be renamable. This state is tracked in the MachineOperand::IsRenamable bit.
Opcode/target constraints: for opcodes that have complex register class requirements (e.g. that depend on other operands/instructions), we set hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq in the machine opcode description. Operands belonging to instructions with opcodes that are marked hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq return false from isRenamable(). Additionally, the AllowRegisterRenaming target property prevents any operands from being marked renamable for targets that don't have detailed opcode hasExtraSrcRegAllocReq/hasExtraDstRegAllocReq values.

◆ print() [1/3]

More complex way of printing a MachineOperand.

Parameters

TypeToPrint	specifies the generic type to be printed on uses and defs. It can be determined using MachineInstr::getTypeToPrint.
OpIdx	- specifies the index of the operand in machine instruction. This will be used by target dependent MIR formatter. Could be std::nullopt if the index is unknown, e.g. called by dump().
PrintDef	- whether we want to print `def` on an operand which isDef. Sometimes, if the operand is printed before '=', we don't print `def`.
IsStandalone	- whether we want a verbose output of the MO. This prints extra information that can be easily inferred when printing the whole function, but not when printing only a fragment of it.
ShouldPrintRegisterTies	- whether we want to print register ties. Sometimes they are easily determined by the instruction's descriptor (MachineInstr::hasComplexRegiterTies can determine if it's needed).
TiedOperandIdx	- if we need to print register ties this needs to provide the index of the tied register. If not, it will be ignored.
TRI	- provide more target-specific information to the printer. Unlike the previous function, this one will not try and get the information from it's parent.
IntrinsicInfo	- same as `TRI`.
