Constructor Detail

PcodeEmit

protected PcodeEmit()

Pcode emitter constructor for empty or unimiplemented instructions

PcodeEmit

public PcodeEmit(ParserWalker walk,
                 InstructionContext ictx,
                 int fallOffset,
                 PcodeOverride override,
                 UniqueAddressFactory uniqueFactory)

Pcode emitter constructor

Parameters:

walk - is the ParserWalker state for the tree that needs to be walked to generate pcode

ictx - is the InstructionContext interface to resolve requests for context

fallOffset - default instruction fall offset (i.e., instruction length including delay slotted instructions)

override - required if pcode overrides are to be utilized

uniqueFactory - required when override specified or if overlay normalization is required
