Typedef Documentation

MCInstrDesc

typedef struct MCInstrDesc MCInstrDesc

MCInstrDesc - Describe properties that are true of each instruction in the target description file. This captures information about side effects, register use and many other things. There is one instance of this struct for each target instruction class, and the MachineInstr class points to this struct directly to describe itself.

MCOperandInfo

typedef struct MCOperandInfo MCOperandInfo

MCOperandInfo - This holds information about one operand of a machine instruction, indicating the register class for register operands, etc.

Enumeration Type Documentation

anonymous enum

anonymous enum

MCInstrDesc flags - These should be considered private to the implementation of the MCInstrDesc class. Clients should use the predicate methods on MCInstrDesc, not use these directly. These all correspond to bitfields in the MCInstrDesc::Flags field.

MCOI_OperandFlags

enum MCOI_OperandFlags

OperandFlags - These are flags set on operands, but should be considered private, all access should go through the MCOperandInfo accessors. See the accessors for a description of what these are.
