Method Details

clone

public Instr clone(CloneInfo ii)

Description copied from class: Instr

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Specified by:

clone in class Instr

Parameters:

ii - This object manages renaming of variables and labels, handles args and return values.

Returns:

a new instruction that can be used in the target scope.

getEvent

public RubyEvent getEvent()

getName

public String getName()

getFilename

public String getFilename()

getLinenumber

public int getLinenumber()

toStringNonOperandArgs

public String[] toStringNonOperandArgs()

Overrides:

toStringNonOperandArgs in class Instr

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Instr

decode

public static TraceInstr decode(IRReaderDecoder d)

interpret

public Object interpret(ThreadContext context,
 StaticScope currScope,
 DynamicScope currDynScope,
 IRubyObject self,
 Object[] temp)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr

computeScopeFlags

public boolean computeScopeFlags(IRScope scope,
 EnumSet<IRFlags> flags)

Description copied from class: Instr

Does this instruction do anything the scope is interested in?

Overrides:

computeScopeFlags in class Instr

Returns:

true if it modified the scope or set any flags.
