Method Detail

resolveDynamicInvocation

static DynamicLink resolveDynamicInvocation()

Discovers a method reference to be invoked via dynamic bridge. The call stack is examined to find the invocation site.

Returns:

an DynamicLink describing the call site

resolveMethodRef

static RVMMethod resolveMethodRef(DynamicLink dynamicLink)

Resolves a method ref into appropriate RVMMethod.

Parameters:

dynamicLink - a DynamicLink that describes call site

Returns:

the RVMMethod that should be invoked.

compileMethod

static void compileMethod(DynamicLink dynamicLink,
                          RVMMethod targetMethod)

Compile (if necessary) targetMethod and patch the appropriate dispatch tables.

Parameters:

dynamicLink - a DynamicLink that describes call site.

targetMethod - the RVMMethod to compile (if not already compiled)
