Correct Volatile SGET/SPUT format tag, add missing cases for JIT

Fix for http://b/issue?id=2971877, which was identified via
debug tracing on http://b/issue?id=2971569.  There were a couple
of problems: first, the volatile sget/sput byte codes had the
wrong format tag (22c instead of 21c).  Second, the JIT was missing
a couple of case statments to handle these.  As far as the JIT goes,
this would not have caused correctness problems, but would have
been slower than necessary.

13 years agoCollect method traces with the fast interpreter and the JIT'ed code.
Ben Cheng [Tue, 31 Aug 2010 16:30:37 +0000 (09:30 -0700)]
Collect method traces with the fast interpreter and the JIT'ed code.

Insert inline code instead of switching to the debug interpreter in the hope
that the time stamps collected in traceview are more close to the real
world behavior with minimal profiling overhead.

Because the inline polling still introduces additional overhead (20% ~ 100%),
it is only enabled in the special VM build called "libdvm_traceview.so".
It won't work on the emulator because it is not implemented to collect the
detailed instruction traces.

Here are some performance numbers using the FibonacciSlow microbenchmark
(ie recursive workloads / the shorter the faster):

       time: configuration
  8,162,602: profiling off/libdvm.so/JIT off
  2,801,829: profiling off/libdvm.so/JIT on
  9,952,236: profiling off/libdvm_traceview.so/JIT off
  4,465,701: profiling off/libdvm_traceview.so/JIT on

 11,231,707: profiling on/libdvm_traceview.so/JIT off
  8,427,846: profiling on/libdvm_traceview.so/JIT on

Comparing the 8,427,846 vs 164,664,634 numbers againt the true baseline
performance number of 2,801,829, the new libdvm_traceview.so improves the time
skew from 58x to 3x.

Move the finger computation out of the bitmap scanning callback.

The finger computation depends on bitmap internals.  This knowledge
should not be part of the bitmap interface, just its implementation.
This change adds a new walker that computes and passes a finger

end address during a walk has been removed from the ordinary bitmap
walker code.  That check is needed by the scanning walk as its
callback may advance the max address when setting mark bits for
objects beyond the finger.

Carl Shapiro [Tue, 31 Aug 2010 23:48:31 +0000 (16:48 -0700)]
Move the finger computation out of the bitmap scanning callback.

The finger computation depends on bitmap internals.  This knowledge
should not be part of the bitmap interface, just its implementation.
This change adds a new walker that computes and passes a finger
argument to a callback.  As part of this change, code to recompute the
end address during a walk has been removed from the ordinary bitmap
walker code.  That check is needed by the scanning walk as its
callback may advance the max address when setting mark bits for
objects beyond the finger.

Show CPU# and utime/stime in the Dalvik thread dump.

This adds the "CPU number last executed on" from /proc/stat to
the Dalvik thread output.  This may come in handy when looking at
thread dumps.  While I was at it I added the utime/stime values,
which may not be all that useful since they represent lifetime usage
rather than recent usage.

Output appears on the schedstat line:
  | schedstat=( 2930542006 9197204583 1284 ) ut=287 st=6 core=0

The routine that parses /proc/stat, previously only used for DDMS, has
been generalized.  This also fixes a problem with parsing threads
whose name includes a space.

I also changed this and the /proc/schedstat code to use /proc/self
instead of /proc/%d + getpid().
