asmjit::x86::Gp Class Reference [¶]

Inheritance diagram for asmjit::x86::Gp:
asmjit::UniGp asmjit::Reg asmjit::Operand asmjit::Operand_

General purpose register (X86|X86_64).

To get a specific register you can use:

  • specific registers directly, like x86::eax or x86::rbx, etc...
  • construct a register operand dynamically, like x86::gp8(id), x86::gp64(id), etc...
  • use Gp::make_r[8|8lo|8hi|16|32|64](id) API for convenience

To cast a register to a specific type, use Gp::r8(), Gp::r8_lo(), Gp::r8_hi(), Gp::r16(), Gp::r32(), and Gp::r64() member functions. Each cast first clones the register and then changes its signature to match the register it has been casted to.

x86::Gp::Id : uint32_tenum[¶]

Physical id (X86|X86_64).

Note

Register indexes have been reduced to only support general purpose registers. There is no need to have enumerations with number suffix that expands to the exactly same value as the suffix value itself.
