Invalid or uninitialized instruction id.


Abstract instruction (BaseBuilder and BaseCompiler).

Constructor & Destructor Documentation

BaseInst::BaseInst(InstId instId = 0, InstOptions options = InstOptions::kNone)explicitnoexcept

Creates a new BaseInst instance with id and options set.

Default values of id and options are zero, which means 'none' instruction. Such instruction is guaranteed to never exist for any architecture supported by AsmJit.

Member Function Documentation

InstId BaseInst::id() constnoexcept

Returns the instruction id with modifiers.

void BaseInst::setId(InstId id)noexcept

Sets the instruction id and modiiers from id.

void BaseInst::resetId()noexcept

Resets the instruction id and modifiers to zero, see kIdNone.

InstId BaseInst::realId() constnoexcept

Returns a real instruction id that doesn't contain any modifiers.
