Enums§

  • AluRmROpcode
    Internal type AluRmROpcode: defined at src/isa/x64/inst.isle line 756.
  • AluRmiROpcode
    Some basic ALU operations.
  • Amode
    Internal type Amode: defined at src/isa/x64/inst.isle line 1021.
  • Avx512Opcode
    Internal type Avx512Opcode: defined at src/isa/x64/inst.isle line 1398.
  • Avx512TupleType
  • AvxOpcode
    Internal type AvxOpcode: defined at src/isa/x64/inst.isle line 1207.
  • CC
    These indicate condition code tests. Not all are represented since not all are useful in compiler-generated code.
  • CmpOpcode
    Comparison operations.
  • DivSignedness
    Internal type DivSignedness: defined at src/isa/x64/inst.isle line 719.
  • ExtKind
    This defines the ways a value can be extended: either signed- or zero-extension, or none for types that are not extended. Contrast with ExtMode, which defines the widths from and to which values can be extended.
  • ExtMode
    These indicate ways of extending (widening) a value, using the Intel naming: B(yte) = u8, W(ord) = u16, L(ong)word = u32, Q(uad)word = u64
  • FcmpImm
    Encode the ways that floats can be compared. This is used in float comparisons such as cmpps, e.g.; it is distinguished from other float comparisons (e.g. ucomiss) in that those use EFLAGS whereas FcmpImm is used as an immediate.
  • FenceKind
    An x64 memory fence kind.
  • Imm8Reg
    An operand which is either an 8-bit integer immediate or a register.
  • OperandSize
    An operand’s size in bits.
  • RegMem
    An operand which is either an integer Register or a value in Memory. This can denote an 8, 16, 32, 64, or 128 bit value.
  • RegMemImm
    An operand which is either an integer Register, a value in Memory or an Immediate. This can denote an 8, 16, 32 or 64 bit value. For the Immediate form, in the 8- and 16-bit case, only the lower 8 or 16 bits of simm32 is relevant. In the 64-bit case, the value denoted by simm32 is its sign-extension out to 64 bits.
  • RoundImm
    Encode the rounding modes used as part of the Rounding Control field. Note, these rounding immediates only consider the rounding control field (i.e. the rounding mode) which only take up the first two bits when encoded. However the rounding immediate which this field helps make up, also includes bits 3 and 4 which define the rounding select and precision mask respectively. These two bits are not defined here and are implictly set to zero when encoded.
  • ShiftKind
    These indicate the form of a scalar shift/rotate: left, signed right, unsigned right.
  • SseOpcode
    Some SSE operations requiring 2 operands r/m and r.
  • SyntheticAmode
    A Memory Address. These denote a 64-bit value only. Used for usual addressing modes as well as addressing modes used during compilation, when the moving SP offset is not known.
  • UnaryRmRImmVexOpcode
    Internal type UnaryRmRImmVexOpcode: defined at src/isa/x64/inst.isle line 775.
  • UnaryRmROpcode
    Unary operations requiring register or memory and register operands.
  • UnaryRmRVexOpcode
    Internal type UnaryRmRVexOpcode: defined at src/isa/x64/inst.isle line 770.
