This file describes how to lower LLVM code to machine code.
Class for arbitrary precision integers.
This is an important base class in LLVM.
This class represents an Operation in the Expression.
A parsed version of the target data layout string in and methods for querying it.
This is an important class for using LLVM in a threaded context.
Representation of each machine instruction.
Wrapper class representing virtual and physical registers.
Wrapper class for IR location info (IR ordering and DebugLoc) to be passed into SDNode creation funct...
Represents one node in the SelectionDAG.
Unlike LLVM values, Selection DAG nodes may return multiple values as the result of a computation.
This is used to represent a portion of an LLVM function in a low-level Data Dependence DAG representa...
This class consists of common code factored out of the SmallVector class to reduce code duplication b...
StringRef - Represent a constant reference to a string, i.e.
virtual bool isZExtFree(Type *FromTy, Type *ToTy) const
Return true if any actual instruction that defines a value of type FromTy implicitly zero-extends the...
This class defines information used to lower LLVM code to legal SelectionDAG operators that the targe...
Primary interface to the complete machine description for the target machine.
TargetRegisterInfo base class - We assume that the target defines a static array of TargetRegisterDes...
The instances of the Type class are immutable: once they are created, they are never changed.
MVT getScalarShiftAmountTy(const DataLayout &DL, EVT) const override
Return the type to use for a scalar shift opcode, given the shifted amount type.
bool isZExtFree(SDValue Val, EVT VT2) const override
Return true if zero-extending the specific node Val to type VT2 is free (either because it's implicit...
MachineBasicBlock * EmitInstrWithCustomInserter(MachineInstr &MI, MachineBasicBlock *MBB) const override
This method should be implemented by targets that mark instructions with the 'usesCustomInserter' fla...

If a physical register, this returns the register that receives the exception address on entry to an ...
bool isLegalAddressingMode(const DataLayout &DL, const AddrMode &AM, Type *Ty, unsigned AS, Instruction *I=nullptr) const override
isLegalAddressingMode - Return true if the addressing mode represented by AM is legal for this target...
SDValue LowerOperation(SDValue Op, SelectionDAG &DAG) const override
LowerOperation - Provide custom lowering hooks for some operations.
void ReplaceNodeResults(SDNode *N, SmallVectorImpl< SDValue > &Results, SelectionDAG &DAG) const override
ReplaceNodeResults - Replace the results of node with an illegal result type with new values built ou...
unsigned getJumpTableEncoding() const override
Return the entry encoding for a jump table in the current function.

@ BUILTIN_OP_END
BUILTIN_OP_END - This must be the last enum value in this list.
This is an optimization pass for GlobalISel generic memory operations.
This structure contains all information that is necessary for lowering calls.
