9 years agoJDWP: properly combine location events
Sebastien Hertz [Fri, 10 Apr 2015 10:12:33 +0000 (12:12 +0200)]
JDWP: properly combine location events

This CL properly groups JDWP events at the same location: Breakpoint,
Single-step, Method Entry and Method Exit. This is necessary if the
debugger is not the only instrumentation listener. This matches the
behavior of Dalvik, especially for methods with a single return
instruction.

The interpreter was tuned so the instrumentation callbacks were
called to satisfy the debugger with the idea the debugger was the
only instrumentation listener. This is not true when method tracing
is enabled at the same time.
When tracing is enabled, there is always a listener for MethodEntry
and MethodExit events (art::Trace class). However, if the debugger
is only listening to DexPcMoved event (to manage JDWP Breakpoint
event), it will not be notified of this event.

We now properly call all the instrumentation callbacks in the
interpreter and move the logic specific to debugging into the class
DebugInstrumentationListener. This allows to properly group JDWP
location events together depending on the sequence of instrumentation
callbacks.

We add Thread::tls_32bit_sized_values::debug_method_entry_ flag to
remember we just entered a method. It replaces the local variable
notified_method_entry_event in the interpreter and simplifies the
code.

Bump oat version to force recompilation because the layout of the
Thread class is modified.

Quick: Avoid unnecessary GVN work in release builds.

In GVN's post-processing phase, compare LVNs only in debug
builds as they should be equal anyway.

Remove the Gate() from GVN cleanup pass and remove the
DCHECK() from MIRGraph::GlobalValueNumberingCleanup()
to make it a no-op if the GVN didn't run.

We add the following to the loop pre-header:

We also take care of indexing with induction variable plus some offsets,
like array[i - 1]/array[i + 1] inside the loop, and adjust the condition
for deoptimization accordingly.
