C++ (Cpp) ProfileStackTrace Examples

Example #1

File: memory-profile.cpp Project: Mo-k-tec/hhvm

// stack trace helper
static ProfileStackTrace getStackTrace() {
  ProfileStackTrace trace;

  if (g_context.isNull()) return trace;
  VMRegAnchor _;
  ActRec *fp = vmfp();
  if (!fp) return trace;
  PC pc = vmpc();

  const Func *f = fp->m_func;
  Unit *u = f->unit();
  Offset off = pc - u->entry();
  for (;;) {
    trace.push_back({ f, off, fp->resumed() });
    fp = g_context->getPrevVMStateUNSAFE(fp, &off);
    if (!fp) break;
    f = fp->m_func;
  }
  return trace;
}

Example #2

File: memory-profile.cpp Project: Alienfeel/hhvm

// stack trace helper
static ProfileStackTrace getStackTrace() {
  ProfileStackTrace trace;

  if (g_context.isNull()) return trace;
  JIT::VMRegAnchor _;
  ActRec *fp = g_vmContext->getFP();
  if (!fp) return trace;
  PC pc = g_vmContext->getPC();

  const Func *f = fp->m_func;
  Unit *u = f->unit();
  Offset off = pc - u->entry();
  for (;;) {
    trace.push_back({ f, off });
    fp = g_vmContext->getPrevVMState(fp, &off);
    if (!fp) break;
    f = fp->m_func;
  }
  return trace;
