Class ForeignCallDescriptor

java.lang.Object

com.oracle.graal.compiler.common.spi.ForeignCallDescriptor

public class ForeignCallDescriptor
extends Object

The name and signature of a foreign call. A foreign call differs from a normal compiled Java call in at least one of these aspects:

• The call is to C/C++/assembler code.
• The call uses different conventions for passing parameters or returning values.
• The callee has different register saving semantics. For example, the callee may save all registers (apart from some specified temporaries) in which case the register allocator doesn't not need to spill all live registers around the call site.
• The call does not occur at an INVOKE* bytecode. Such a call could be transformed into a standard Java call if the foreign routine is a normal Java method and the runtime supports linking Java calls at arbitrary bytecodes.
