Mathieu Chartier [Thu, 23 Oct 2014 00:18:34 +0000 (17:18 -0700)]
Fix concurrent start bytes race

Previously, we set concurrent start bytes to max int when we
requested a concurrent GC, but there was a race if another thread
was doing another GC and had already completed GrowForUtilization
but had not yet finished the GC. This meant that the thread doing
the GC would update the concurrent start bytes properly, but the
allocating thread would re-update it to max int. Then when the
concurrent GC thread woke up, it would call WaitForGcToComplete
and see that there was a collector running and avoid doing the
concurrent GC, leaving the concurrent start bytes set to max int.

This meant that there would be no more concurrent GC until either
the next explicit GC or the next GC for alloc.

The fix is to only set concurrent start bytes to max int inside of
the CollectGarbageInternal code such that there isn't any way for
two threads to race.

Don't call dlsym from signal context in signal chain

It is dangerous to call dlsym from within a signal context
since it takes a lock and can lead to a mutex reentry attempt if
timing is bad.

This change adds an initialization function to the signal chain
that calls dlsym for sigaction and sigprocmask from outside the
signal context (from Runtime::Init()).  The results are cached
in a static variable and used from within the signal context if
necessary.

However, tests don't necessarily call Runtime::Init() so we also
need to deal with the case where the signal chain is not initialized
and perform a lazy initialization from inside sigaction or sigprocmask.
This is always outside a signal context since we have not initialized
the runtime.

In almost most cases working with Register Allocator we must first
load source and then evaluate the destination. In this particular case
for byte-code shl-int/2addr v10, v10 we first find a destination (memory)
then load source (v10 -> physical register) and generate a shift operation
on memory. This is ok for this bytecode but RA thinks that v10 is in register
(we loaded source) and this is incorrect because updated value in memory
and physycal register is not up to date.

Print the command line and ABI in stack dumps like debuggerd.

Ensure the heading is "Cmd line:" just like debuggerd and
as it used to be in Dalvik.
Fix a missing newline.
Trim all training nulls from the command line.
Don't bother printing the original command line if unset.
Add the ABI to the dump to help the native stack symbol tool.

VMClassLoader.findLoadedClass now calls FindClassInPathClassLoader
as a fast path. Exclusive time results (trace view maps launch):

Before:

Delete pin table

The pin table was brought over from dalvik but not really needed
since ART doesn't support pinning in movable spaces. The only
thing it did was hold objects live for JNI functions.
This shouldn't be necessary since people keep jni references to
these objects or else they could never release the elements.
