shark + assertions + llvm2.6

[Xerxes Rånby]

Hi Gary!

I tested building a debuggable shark with assertions enabled using the 
current llvm 2.6 svn trunk on X86.

I have one assertion that fails when running trivial stuff like java 
-version
I wanted to know your opinion if this IA32_ONLY assertion in
/openjdk-ecj/hotspot/src/share/vm/interpreter/bytecodeInterpreter.cpp:424
are valid for shark or should i simply ignore it?

Cheers
Xerxes


================================================= assertion block around 
bytecodeInterpreter.cpp:424
#ifdef ASSERT
  if (istate->_msg != initialize) {
    assert(abs(istate->_stack_base - istate->_stack_limit) == 
(istate->_method->max_stack() + 1), "bad stack limit");
  IA32_ONLY(assert(istate->_stack_limit == 
istate->_thread->last_Java_sp() + 1, "wrong"));
  }
  // Verify linkages.
  interpreterState l = istate;
  do {
    assert(l == l->_self_link, "bad link");
    l = l->_prev_link;
  } while (l != NULL);
  // Screwups with stack management usually cause us to overwrite istate
  // save a copy so we can verify it.
  interpreterState orig = istate;
#endif
