Method Details

allocateInterpreterContext

public InterpreterContext allocateInterpreterContext(List<Instr> instructions,
 int temporaryVariableCount,
 EnumSet<IRFlags> flags)

Description copied from class: IRScope

Make version specific to scope which needs it (e.g. Closure vs non-closure).

Overrides:

allocateInterpreterContext in class IRScope

allocateInterpreterContext

public InterpreterContext allocateInterpreterContext(Supplier<List<Instr>> instructions,
 int temporaryVariableCount,
 EnumSet<IRFlags> flags)

Description copied from class: IRScope

Make version specific to scope which needs it (e.g. Closure vs non-closure).

Overrides:

allocateInterpreterContext in class IRScope

setIsEND

public void setIsEND()

isEND

public boolean isEND()

isWhereFlipFlopStateVariableIs

public boolean isWhereFlipFlopStateVariableIs()

Overrides:

isWhereFlipFlopStateVariableIs in class IRScope

getNextClosureId

public int getNextClosureId()

Overrides:

getNextClosureId in class IRScope

getNewLabel

public Label getNewLabel()

Overrides:

getNewLabel in class IRScope

getScopeType

public IRScopeType getScopeType()

Specified by:

getScopeType in class IRScope

isTopLocalVariableScope

public boolean isTopLocalVariableScope()

Overrides:

isTopLocalVariableScope in class IRScope

toStringBody

public String toStringBody()

getBlockBody

public BlockBody getBlockBody()

isNestedClosuresSafeForMethodConversion

public boolean isNestedClosuresSafeForMethodConversion()

convertToMethod

public IRMethod convertToMethod(ByteList name)

setSignature

public void setSignature(Signature signature)

setSource

public void setSource(IterNode iter)

findExistingLocalVariable

protected LocalVariable findExistingLocalVariable(RubySymbol name,
 int scopeDepth)

Overrides:

findExistingLocalVariable in class IRScope

getNewLocalVariable

public LocalVariable getNewLocalVariable(RubySymbol name,
 int depth)

Overrides:

getNewLocalVariable in class IRScope

getLocalVariable

public LocalVariable getLocalVariable(RubySymbol name,
 int depth)

Description copied from class: IRScope

Find or create a local variable. By default, scopes are assumed to only check current depth. Blocks/Closures override this because they have special nesting rules.

Overrides:

getLocalVariable in class IRScope

cloneForInlining

protected IRClosure cloneForInlining(CloneInfo ii,
 IRClosure clone)

cloneForInlining

public IRClosure cloneForInlining(CloneInfo ii)

getSignature

public Signature getSignature()

getArgumentDescriptors

public ArgumentDescriptor[] getArgumentDescriptors()

setArgumentDescriptors

public void setArgumentDescriptors(ArgumentDescriptor[] argDesc)

Set upon completion of IRBuild of this IRClosure.

persistScopeHeader

public void persistScopeHeader(IRWriterEncoder file)

Overrides:

persistScopeHeader in class IRScope
