[Jikesrvm-core] jdp break option

[Arvin S. <ar...@us...>]

  I've just added an option that should make it  easier to  use jdp. jdp
can't break in a method until it has  been compiled. The mechanism that I
just added allows you to get control  just after a method has been compiled
and before it is executed.

  Suppose I want to step  through methodFoo.

  On the command  line, I would  say:

    -X:base:method_to_break=methodFoo                          // This uses
the same matching rules as method_to_print

  Then, under jdp, I'd set a breakpoint in breakStub        // This new
method will only be invoked based on the method_to_break option

  When I stop in breakStub, I'd then be able to set a breakpoint  in
methodFoo  itself.

Regards,
Arvin
