I am presuming the JVM interpreter is defined/implemented in the the hotspot
module since this is a JVM implementation.
I cannot seem to find *any* instruction in it that gets called by a simple
"./java -ea Class" call. We are stumped.
For instance there are methods for local set and reference:
void BytecodeInterpreter::set_stack_slot(intptr_t *tos, address value, int
offset) {
*((address *)&tos[Interpreter::expr_index_at(-offset)]) = value;
}
void BytecodeInterpreter::set_stack_object(intptr_t *tos, oop value, int
offset) {
*((oop *)&tos[Interpreter::expr_index_at(-offset)]) = value;
}
These (and similar in same file) are not being called at all during the JVM
interpreter phase (simple java program as reference). My program creates an
object and calls a test method with a single object as reference.
What could be the hang up? No printf statement seems to work.
Thanks.
