JDWP: fix breakpoint for method in the image
When we set a breakpoint in a compiled method, we deoptimize it by
changing its entrypoint so it is executed with the interpreter.
However, methods in the image can be called with their direct code
pointer, ignoring the updated entrypoint. In that case, the method
is not executed with the interpreter and we miss the breakpoint.
This CL avoids that situation by forcing a full deoptimization so
everything runs with the interpreter. However, if the image has been
compiled in PIC mode, we keep using selective deoptimization because
direct code pointer is not used in this mode.

Print more info in MarkSweep::VerifyRoot
Refactored old root callback to use a new class called RootInfo.
RootInfo contains all the relevant info related to the root
associated with the callback. The MarkSweep::VerifyRoot function
now uses this info to print the StackVisitor's described location
if the GC root is of the type kRootJavaFrame.
Some other cleanup.
Example output:
E/art (12167): Tried to mark 0x123 not contained by any spaces
E/art (12167): Attempting see if it's a bad root
E/art (12167): Found invalid root: 0x123 with type RootJavaFrame
E/art (12167): Location=Visiting method
'void java.lang.Runtime.gc()' at dex PC 0xffffffff (native PC 0x0)

ART: Simple structural class check
Adds a simple check to class-loading when the embedded dex file in
an oat file and the dex file on the class path where we found the
class do not match.
We require that the number of methods and fields do not change, as
that will almost certainly mean that quickened and other compiled
offsets are wrong now. This is a reasonably lightweight change, but
we should investigate a full comparison including name and type of
members.

ART: More ELF and oat file safety measures
In an ELF file, look for a shstrtab section when loading in
program-header-only mode. If the section is outside the file size,
it strongly indicates a broken compile.
When compiling oat files in the class linker, explicitly unlink
on failure. This should catch cases when dex2oat is killed or
crashes and doesn't have a chance to delete its (partial) output.

Ensure void type is resolved when running without image
To initialize java.lang.Void correctly, we need to ensure the 'void'
class is initialized in the dex cache of core-libart (because Java
code relies on it). However, if we run without image, the dex cache
may not contain the void class before we initialize java.lang.Void
class.
This CL fixes this by forcing the resolution of 'void' class when
initializing the runtime without image.
We also generalize that to other types by not skipping verification
when running with preopted oat files without image. By verifying
all classes, we ensure all resolved types are in the dex caches.

Set dex_cache_strings_ when we call Class::SetDexCache
Ensures that these two variables never get out of sync. The error
was presumably related to not doing this for proxy classes. This
caused java code which was looking at the dex_cache_strings_ field
to incorrectly access a null array.

JDWP: only deoptimize when it is required
We don't need to deoptimize anything when we forced the use of the
interpreter (-Xint). In this case, no compiled code is executed
(except native methods which are not concerned by deoptimization).
Therefore we even don't need to enable/disable deoptimization support
in instrumentation.
We also don't need to deoptimize a method that hasn't been compiled.
Since it will run with interpreter, there is no point deoptimizing
it. However this method may be inlined in a compiled caller method
so we still need to deoptimize everything in this case.
This CL updates breakpoint support by storing the required kind of
deoptimization for a particular method. There are 3 cases:
- kNothing: the method does not require deoptimization.
- kSelectiveDeoptimization: the method needs to be deoptimized.
- kFullDeoptimization: we must deoptimize everythinig.
When uninstalling a breakpoint, we need to do the reverse operation.
Also fixes the SanityCheckExistingBreakpoints function to control
breakpoints related to the given method only and adds extra verbose
ilogs when choosing the appropriate deoptimization kind.
Includes a partial cherry-pick of commit
87553c9fa1298ffb40127b2bb6413859fd3f79df to use method
ClassLinker::GetOatMethodQuickCodeFor.

Change 64 bit ArtMethod fields to be pointer sized
Changed the 64 bit entrypoint and gc map fields in ArtMethod to be
pointer sized. This saves a large amount of memory on 32 bit systems.
Reduces ArtMethod size by 16 bytes on 32 bit.
Total number of ArtMethod on low memory mako: 169957
Image size: 49203 methods -> 787248 image size reduction.
Zygote space size: 1070 methods -> 17120 size reduction.
App methods: ~120k -> 2 MB savings.
Savings per app on low memory mako: 125K+ per app
(less active apps -> more image methods per app).
Savings depend on how often the shared methods are on dirty pages vs
shared.
TODO in another CL, delete gc map field from ArtMethod since we
should be able to get it from the Oat method header.

Improve dex location canonicalization-related performance.
Eagerly add canonical dex file locations to the OatFile's
primary lookup map in Setup(). This moves the boot.oat work
from every app startup to the zygote initialization. Since
we always ended up initializing the canonical location map
anyway due to the way that we're loading dex files, the lazy
initialization didn't save anything.
Clean up dex file name canonicalization to make sure we
free() the memory returned by realpath() rather than using
std::unique_ptr<> with the default deleter.
Avoid some unnecessary duplicate OatDexFile lookups.

If we are using the PathClassLoader with a BootClassLoader
parent, we can handle the common case in the FindClass function
without needing to go back to java code.
Around 10% speedup measured of maps launch, could be noise due to
large variation of app launch times. Eliminates defineClassNative

Reduce and speed-up class def searches.
Use the class linker for descriptor lookups from the compile driver so that
dex caches are populated.
Reduce the scope of functions for scanning class paths to just the class
linker where they are performed.
If we see more than a threshold number of find class def misses on a dex file
lazily compute an index, so that future lookups are constant time (part of the
collection code is taken from
https://android-review.googlesource.com/#/c/103865/3). Note that we take a lazy
approach so that we don't serialize on loading dex files, this avoids the
reason the index was removed in 8b2c0b9abc3f520495f4387ea040132ba85cae69.
Remove an implicit and unnecessary std::string creation for PrintableString.
Single threaded interpret-only dex2oat performance is improved by roughly 10%.

Avoid use of std::string where we have const char*.
Removing the ClassHelper caused std::string creation for all calls to
Class::GetDescriptor and a significant performance regression. Make the
std::string an out argument so the caller can maintain it and its life time
while allowing GetDescriptor to return the common const char* case.
Don't generate GC maps when compilation is disabled.
Remove other uses of std::string that are occuring on critical paths.
Use the cheaper SkipClass in CompileMethod in CompilerDriver.
Specialize the utf8 as utf16 comparison code for the common shorter byte
encoding.
Force a bit of inlining, remove some UNLIKELYs (they are prone to pessimizing
code), add some LIKELYs.

Set vtable in class object to null after linking.
This is follow-up work of embedding imt and vtable for

Add GcRoot to clean up and enforce read barriers.
Introduce a value-type wrapper around Object* for GC roots so that 1)
we won't have to directly add the read barrier code in many places and
2) we can avoid accidentally bypassing/missing read barriers on GC
roots (the GcRoot interface ensures that the read barrier is executed
on a read).
The jdwp test passed.

ART: Key-Value Store in Oat header

first significant use of this is storing the implicit-check flags,
so that an oat file can be rejected if it doesn't agree with the

Bump the oat version as the header structure changes.

ART: Native support for multidex
Native support for zip files with multiple classesX.dex.
Works by explicitly looking for those files in ascending order. As
these files have no file system representation for themselves,
introduce synthetic dex locations: the name of the originating file
plus a colon plus the name of the dex file, e.g., test.jar:classes2.dex.
Opening a zip dex file will return all dex files in this way. This
keeps the changes to dex2oat minimal.
To hide multidex/synthetic names from the Java layer, let the handle
of dalvik.system.DexFile refer to a vector of DexFile objects. When
opening a location, test possible synthetic names and add them to the
vector. Thus, the original multidex jar in the classpath will be
associated with all embedded dex files.

Add mark compact collector.
The mark compact collector is a 4 phase collection, doing a normal
full mark_sweep, calculating forwarding addresses of objects in the
from space, updating references of objects in the from space, and
moving the objects in the from space.
Support is diabled by default since it needs to have non movable
classes and field arrays. Performance numbers is around 50% as fast.
The main advantage that this has over semispace is that the worst
case memory usage is 50% since we only need one space isntead of two.
TODO: Make field arrays and classes movable. This causes complication
since Object::VisitReferences relies on these, so if we update the
fields of an object but another future object uses this object to
figure out what fields are reference fields it doesn't work.

Add locking around boot image generation.
If zygote aborts due to an error, it will restart and
spawn another dex2oat process while the old one is still
running. If this happens fast enough, the system will
eventually need a kernel reboot since neither the zygote
nor dex2oat are killable.
This brings boot image generation in line with dex2oat
generation, which uses a similar pattern of advisory
locking.

Fix generic jni issue in ArtMethod::GetQuickFrameInfo
The 64-bit host mode fails to start due to incorrect
detection of GetQuickGenericJniTrampoline.
The quick_code is 32-bit and taken from oat file, but
GetQuickGenericJniTrampoline returnf 0x7fffxx (64-bit)
address of trampoline and execution went to incorrect way.
Some clean-up.

Improve ValidateSuperClassDescriptors performance.
ValidateSuperClassDescriptors uses FindClass with the 2 class loaders that are
being used in validating method parameter types. The use of 2 class loaders
ensures at least one miss with LookupClass and thereby a call to
ClassLoader.loadClass which will then defer to the parent class loader eating
time. This change modifies the behavior to instead lookup types with a dex
cache, so that resolution and load class are only performed once per type.

by value thus avoiding one or two heap allocations per call.

Speed up single-stepping
During single-stepping sequence, we need to deoptimize everything when we
register a single-step event and undeoptimize everything when it is done. This
causes a slow pattern where we continuously deoptimize-undeoptimize everything
for each single-step.
This CL introduces a special handling of single-step undeoptimization. We now
delay the undeoptimization to the next resume (one thread or all threads) or
the end of the debugging session. Indeed, a single-step event registration is
always followed by a resume command.
At the "resume" point, we know if a single-step event is registered and if we
really need to undeoptimize. At the "registration" point, we know we did not
undeoptimized everything so we don't need to deoptimize everything again.
Therefore, in a sequence of single-steps, we only do a full deoptimization for
the first single-step and a full undeoptimization for the last single-step.
We update logs at deoptimization points so we can track more precisely. Note
they are verbose logs that still must be enabled with -verbose:jdwp option.
We also make some improvement inside instrumentation:
* updates Instrumentation::ShouldNotifyMethodEnterExitEvents to comply with its
name.
* compute frame id only once when looking for the corresponding instrumentation
frame.
* compute the OatMethod once in ClassLinker::GetPortableOatCodeFor to avoid
looking for it again.

Implicit null/suspend checks (oat version bump)
This adds the ability to use SEGV signals
to throw NullPointerException exceptions from Java code rather
than having the compiler generate explicit comparisons and
branches. It does this by using sigaction to trap SIGSEGV and when triggered
makes sure it's in compiled code and if so, sets the return
address to the entry point to throw the exception.
It also uses this signal mechanism to determine whether to check
for thread suspension. Instead of the compiler generating calls
to a function to check for threads being suspended, the compiler
will now load indirect via an address in the TLS area. To trigger
a suspend, the contents of this address are changed from something
valid to 0. A SIGSEGV will occur and the handler will check
for a valid instruction pattern before invoking the thread
suspension check code.
If a user program taps SIGSEGV it will prevent our signal handler
working. This will cause a failure in the runtime.
There are two signal handlers at present. You can control them
individually using the flags -implicit-checks: on the runtime
command line. This takes a string parameter, a comma
separated set of strings. Each can be one of:
none switch off
null null pointer checks
suspend suspend checks
all all checks
So to switch only suspend checks on, pass:
-implicit-checks:suspend
There is also -explicit-checks to provide the reverse once
we change the default.
For dalvikvm, pass --runtime-arg -implicit-checks:foo,bar
The default is -implicit-checks:none
There is also a property 'dalvik.vm.implicit_checks' whose value is the same
string as the command option. The default is 'none'. For example to switch on
null checks using the option:
setprop dalvik.vm.implicit_checks null
It only works for ARM right now.
Bumps OAT version number due to change to Thread offsets.

Avoid marking old class linker and intern table roots during pause.
The new root visiting logic has a concept of a root log which holds
new roots which were added since the start of the GC. This is an
optimization since it lets us only mark these newly added roots
during the pause (or pre-cleaning) since the other roots intern table
and class linker roots were marked concurrently at the start of the
GC.
Before (EvaluateAndApplyChanges):
MarkConcurrentRoots: Sum: 605.193ms
After:
MarkConcurrentRoots: Sum: 271.858ms
This should also reduce pathological GC pauses which used to be able
to happen when the intern table or class linker became "dirty"
during the concurrent GC.

Avoid std::string allocations for finding an array class.
Introduce ClassLinker::FindArrayClass which performs an array class lookup
given the element/component class. This has a 16 element cache of recently
looked up arrays.
Pass the current thread to ClassLinker Find .. Class routines to avoid calls
to Thread::Current().
Avoid some uses of FindClass in the debugger where WellKnownClasses is a
faster and more compacting GC friendly alternative.

Fix and optimize verify object.
VerifyObject no longer resides in heap. You can now enable
VerifyObject for non-debug builds. VerifyStack is still slow, so it
is now guarded by its own flag.
Fixed the image writer to not use verification at places where
verification fails due to invalid reads.
Fixed RosAlloc to use SizeOf which doesn't call verify object.
Added a flag paremeter to some of the mirror getters / setters to
be able to selectively disable VerifyObject on certain calls.
Optimized the GC to not verify each object multiple times during
object scanning if verify object is enabled.
Added 3 verification options: verify reads, verify this, and verify
writes so that you can select how much verification you want for
mirror getters and setters.
Removed some useless DCHECKs which would slow debug builds without
providing any benefits.
TODO: RosAlloc verification doesn't currently work with verify
objects.

Remove blacklist
Removes the class initialization blacklist and use transaction to detect and
revert class initialization attempting to invoke native method. This only
concerns class initialization happening at compilation time when generating an
image (like boot.art for the system).
In transactional mode, we log every object's field assignment and array update.
Therefore we're able to abort a transaction to restore values of fields and
array as they were before the transaction starts. We also log changes to the
intern string table so we can restore its state prior to transaction start.
Since transactional mode only happens at compilation time, we don't need to log
all these changes at runtime. In order to reduce the overhead of testing if
transactional mode is on/off, we templatize interfaces of mirror::Object and
mirror::Array, respectively responsible for setting a field and setting an
array element.
For various reasons, we skip some specific fields from transaction:
- Object's class and array's length must remain unchanged so garbage collector
can compute object's size.
- Immutable fields only set during class loading: list of fields, method,
dex caches, vtables, ... as all classes have been loaded and verified before a
transaction occurs.
- Object's monitor for performance reason.
Before generating the image, we browse the heap to collect objects that need to
be written into it. Since the heap may still holds references to unreachable
objects due to aborted transactions, we trigger one collection at the end of
the class preinitialization phase.
Since the transaction is held by the runtime and all compilation threads share
the same runtime, we need to ensure only one compilation thread has exclusive
access to the runtime. To workaround this issue, we force class initialization
phase to run with only one thread. Note this is only done when generating image
so application compilation is not impacted. This issue will be addressed in a
separate CL.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.

Move compiler code out of method verifier.
We want to detect small methods for inlining at the end of
the method verification. Instead of adding more compiler
code to the runtime, we create a callback from the runtime
into the compiler, so that we can keep the code there.
Additionally, we move the compiler-related code that was
already in the method verifier to the compiler since it
doesn't really belong to the runtime in the first place.

Added the method verifiers as roots to fix an issue caused by
RegTypes holding a Class*.
Added logic to clear card table in the SemiSpace collector, this

Compacting collector.
The compacting collector is currently similar to semispace. It works by
copying objects back and forth between two bump pointer spaces. There
are types of objects which are "non-movable" due to current runtime
limitations. These are Classes, Methods, and Fields.
Bump pointer spaces are a new type of continuous alloc space which have
no lock in the allocation code path. When you allocate from these it uses
atomic operations to increase an index. Traversing the objects in the bump
pointer space relies on Object::SizeOf matching the allocated size exactly.
Runtime changes:
JNI::GetArrayElements returns copies objects if you attempt to get the
backing data of a movable array. For GetArrayElementsCritical, we return
direct backing storage for any types of arrays, but temporarily disable
the GC until the critical region is completed.
Added a new runtime call called VisitObjects, this is used in place of
the old pattern which was flushing the allocation stack and walking
the bitmaps.
Changed image writer to be compaction safe and use object monitor word
for forwarding addresses.
Added a bunch of added SIRTs to ClassLinker, MethodLinker, etc..
TODO: Enable switching allocators, compacting on background, etc..

Introduce Signature type to avoid string comparisons.
Method resolution currently creates strings to then compare with strings formed
from methods in other dex files. The temporary strings are purely created for
the sake of comparisons. This change creates a new Signature type that
represents a method signature but not as a string. This type supports
comparisons and so can be used when searching for methods in resolution.
With this change malloc is no longer the hottest method during dex2oat (now its
memset) and allocations during verification have been reduced. The verifier is
commonly what is populating the dex cache for methods and fields not declared
in the dex file itself.

StringPiece clean up.
Profile guided clean up.
Try to avoid creating StringPieces with the contents of a dex file where
the length is known.
Try to avoid RegTypeCache::FromDescriptor when there's a class available.
Make ConstantType::ConstantValue inlinable.
Saving of about 50ms from a 2 threaded ThinkFree compile on host.

Use class def index from java.lang.Class.
Bug: 10244719
This removes the computation of the dex file index, when necessary this is
computed by searching the dex file. Its only necessary in
dalvik.system.DexFile.defineClassNative and DexFile::FindInClassPath, the
latter not showing up significantly in profiling with this change.

Fix race in root marking.
There was a race which caused the class linker / intern table to not
become dirty after adding a root. We now guard the is dirty flag by
the corresponding locks to prevent this from occuring. This was
causing roots to be occasionally missed.
Also fixes the bug where we occasionally scan more cards than
needed.

Handle OOMEs in class linker with grace.
Check for OOMEs and then fail due to them in class loading.
Make the compiler driver spot OOMEs during resolution and abort compilation to
avoid needless GC thrash then eventual death.
Allocate the pre-allocated OOME during Runtime::Init as Runtime::Start isn't
called in the context of the compiler/tools.

Don't scan image space when starting runtime.
Bug 10432288.
Find Classes and Strings from dex caches lazily rather than when the image is
loaded.
Make class status changes do notifies when there can be waiters.
For Class lookup there's a pathology if we always search dex caches and
so after 1000 failures move all classes into the class table.
Be consistent in using "const char*" for class linker descriptors as this
most easily agrees with the type in the dex file.
Improve the intern run-test so that it has a case of a literal contained in the
image.
Modify image_test to allow any valid lock word rather than expecting 0, ideally
we wouldn't see inflated monitors but we do due to NotifyAll (see bug 6961405).

Compiler filter update
Tweak of the compiler filter to give better results for applications
which are not dominated by tight arithmetic loops. Deleted
the "DeferCompilation" setting - it didn't differ enough from the
"Space" setting. Added "Everything" setting to support forced
compilation (for images and testing). Previously used "Speed"
for that purpose, but in the speed setting there are some things we
don't want to compile.

Reduce AOT initialization.
When compiling apps there is no need to resolve all types in the dex file, just
those declared in the dex file. There's also no need to initialize static
fields if we can only leave the class in a verified state.
Increase use of CompilerDriver::IsImage.
Move timing of dex2oat setup to before Runtime::Create.
On run-test 056 the performance improvement is an order of magnitude, for
ThinkFree dex2oat time is dominated by compilation and this change has no
effect.

Compilation filter
This CL introduces a static compilation filter mechanism intended
to allow us to reduce compilation time and space requirements until
we have a profiling mechanism in place.
It supports 5 modes of filtering:
o interpret-only (compile nothing)
o deferred-compilation (compile only those methods believe to be
compute-intensive)
o space (optimized for space)
o balanced (best return on space investment)
o speed (compile everything)
A future CL will allow the default filtering mode to be set
via system property. For now, you can pass it in via command
line as follows:
dalvikvm -compiler-filter:[interpret-only|defer-compilation|
space|balanced|speed]
or dex2oat --runtime-arg -compiler-filter:[one of the above modes]
Creating a file named art/SMALL_ART will force the filter
default to interpret-only. Later on we'll move this capability
to a persistent system property.
or modify kDefaultCompilerFilter in runtime.h
It also changes the compiler driver to allow the compilers to
decline to compile a method by return NULL.
