Method Detail

execute

public static void execute(InlineDecision inlDec,
                           IR ir,
                           Instruction callSite)

Execute an inlining decision inlDec for the CALL instruction callSite that is contained in ir.

Parameters:

inlDec - the inlining decision to execute

ir - the governing IR

callSite - the call site to inline

execute

public static GenerationContext execute(InlineDecision inlDec,
                                        GenerationContext parent,
                                        ExceptionHandlerBasicBlockBag ebag,
                                        Instruction callSite)

Return a generation context that represents the execution of inlDec in the context <parent,ebag> for the call instruction callSite.

PRECONDITION: inlDec.isYes()

POSTCONDITIONS: Let gc be the returned generation context.

• gc.cfg.firstInCodeOrder is the entry to the inlined context
• gc.cfg.lastInCodeOrder is the exit from the inlined context
• GenerationContext.transferState(parent, child) has been called.

Parameters:

inlDec - the inlining decision to execute

parent - the caller generation context

ebag - exception handler scope for the caller

callSite - the callsite to execute

Returns:

a generation context that represents the execution of the inline decision in the given context
