numArgs

public int numArgs()

Description copied from class: Procedure

Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.

Overrides:

numArgs in class Procedure

matches

public static boolean matches(java.lang.Object result,
              long count)

apply

public void apply(CallContext ctx)
           throws java.lang.Throwable

Description copied from class: Procedure

Call this Procedure using the explicit-CallContext-convention. The input arguments are (by default) in stack.args; the result is written to ctx.consumer.

Overrides:

apply in class Procedure

Throws:

java.lang.Throwable

compile

public void compile(ApplyExp exp,
           Compilation comp,
           Target target)

Specified by:

compile in interface Inlineable

getReturnType

public Type getReturnType(Expression[] args)

Description copied from class: Procedure

Semi-deprecated - instead should be set at Inline time. FIXME

Overrides:

getReturnType in class Procedure
