Constructor & Destructor Documentation

x86::Mem::Mem()constexprconstexprnoexcept

Creates a default Mem operand that points to [0].

Member Function Documentation

Mem x86::Mem::clone() constconstexprconstexprnoexcept

Clones the memory operand.

Mem x86::Mem::cloneAdjusted(int64_t off) constnoexcept

Creates a copy of this memory operand adjusted by off.

Mem x86::Mem::cloneResized(uint32_t size) constnoexcept

Creates a copy of this memory operand resized to size.

Mem x86::Mem::cloneBroadcasted(Broadcast bcst) constconstexprconstexprnoexcept

Creates a copy of this memory operand with a broadcast bcst.

Reg x86::Mem::baseReg() constnoexcept

Converts memory baseType and baseId to x86::Reg instance.

The memory must have a valid base register otherwise the result will be wrong.

Reg x86::Mem::indexReg() constnoexcept

Converts memory indexType and indexId to x86::Reg instance.

The memory must have a valid index register otherwise the result will be wrong.

bool x86::Mem::hasSize() constconstexprconstexprnoexcept[1/2]

Tests whether the memory operand specifies a size (i.e. the size is not zero).

bool x86::Mem::hasSize(uint32_t s) constconstexprconstexprnoexcept[2/2]

Tests whether the memory operand size matches size s.

uint32_t x86::Mem::size() constconstexprconstexprnoexcept

Returns the size of the memory operand in bytes.

Note

Most instructions would deduce the size of the memory operand, so in most cases it's expected that the returned value would be zero. However, some instruction require the size to select between multiple variations, so in some cases size is required would be non-zero (for example inc [mem], immediate requires size to distinguish between 8-bit, 16-bit, 32-bit, and 64-bit increments.

AddrType x86::Mem::addrType() constconstexprconstexprnoexcept

Returns the address type of the memory operand.

By default, address type of newly created memory operands is always AddrType::kDefault.
