Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force
the runtime to require that all files that are run are relocated, to
prevent attacks based on the known art base address.

Add support for running patchoat on oat files compiled without an image.

Change run-test to have new --prebuild and --relocate flags.

Implement the Global Value Numbering for optimization
purposes. Use it for the null check and range check
elimination as the LVN used to do.

The order of evaluation of basic blocks needs improving as
we currently fail to recognize some obviously identical
values in methods with more than one loop. (There are three
disabled tests that check this. This is just a missed
optimization, not a correctness issue.)

afd9acc30bdd11cdd12d8209eb994cb371c65e33 17-Jun-2014 Ian Rogers <irogers@google.com> Multilib ART host.

Build ART for the host as a multilib project with dalvikvm32 and dalvikvm64
running as 32 or 64-bit repsectfully. Note, currently multilib host builds
are not the default, you make the so by setting BUILD_HOST_64bit=1.
Extend tests to execute in both 32 and 64-bit modes. By default both 32 and
64-bit tests are run, add 32 or 64 to the end of a test name to run it in
purely that flavor.
Given the extra spam, modify oat tests to only generate console output when
the test fails.
Change the test harness so that common commands are run when a test should be
skipped, when it passes or when it fails. Use these commands to generate a
summary of passing, skipped and failing tests. Tests will be skipped if they
are known to be broken or if a test has already failed. Setting the variable
TEST_ART_KEEP_GOING=true will force working tests not to be skipped.
In this change all tests running on the optimizing compiler are marked broken
due to breakages running them in a multilib environment.
Break apart Android.common.mk into its constituent parts, along with other
pieces of reorganization.

Stylistic nit, we refer to make rule targets as targets thereby overloading
the term target. While consistent with make's terminology, its confusing with
the Android notion of target. I've switched to just calling targets rules to
avoid confusion in host tests.

Bug: 13751317
Fix the Mac build:
- disable x86 selector removal that causes OS/X 10.9 kernel panics,
- madvise don't need does zero memory on the Mac, factor into MemMap
routine,
- switch to the elf.h in elfutils to avoid Linux kernel dependencies,
- we can't rely on exclusive_owner_ being available from other pthread
libraries so maintain our own when futexes aren't available (we
can't rely on the OS/X 10.8 hack any more),
- fix symbol naming in assembly code,
- work around C library differences,
- disable backtrace in DumpNativeStack to avoid a broken libbacktrace
dependency,
- disable main thread signal handling logic,
- align the stack in stub_test,
- use $(HOST_SHLIB_SUFFIX) rather than .so in host make file variables.

Not all host tests are passing on the Mac with this change. dex2oat
works as does running HelloWorld.

65fcc2cf3c5cd97b84330c094908f3a6a7a8d4e7 28-Apr-2014 Dave Allison <dallison@google.com> Thumb2 assembler for JNI compiler and optimizing compiler

This provides a programmatic assembler for the thumb2 instruction set for
ARM. The interface is the same as the ARM assembler and the ARM assembler has
been moved into Arm32Assembler. The assembler handles most 16 and 32 bit instructions
and also allows relocations due to branch expansion. It will also rewrite cbz/cbnz
instructions if they go out of range.

It also changes the JNI compiler to use the thumb2 assembler as opposed
to forcing it to use ARM32. The trampoline compiler still uses ARM due to the
way it returns the address of its generated code. A trampoline in thumb2 is the
same size as that in ARM anyway (8 bytes).

Provides gtest for testing the thumb2 instruction output. This gtest only runs
on the host as it uses arm-eabi-objdump to disassemble the generated code. On the
target the output is not checked but the assembler will still be run to perform
all its checks.

This is a "by-the-book" implementation. It currently only deals
with allocating registers, with no hint optimizations.

The changes remaining to make it functional are:
- Allocate spill slots.
- Resolution and placements of Move instructions.
- Connect it to the code generator.

a5b8fde2d2bc3167078694fad417fddfe442a6fd 23-May-2014 Vladimir Marko <vmarko@google.com> Rewrite BitVector index iterator.

The BitVector::Iterator was not iterating over the bits but
rather over indexes of the set bits. Therefore, we rename it
to IndexIterator and provide a BitVector::Indexes() to get
a container-style interface with begin() and end() for range
based for loops.

Also, simplify InsertPhiNodes where the tmp_blocks isn't
needed since the phi_nodes and input_blocks cannot lose any
blocks in subsequent iterations, so we can do the Union()
directly in those bit vectors and we need to repeat the loop
only if we have new input_blocks, rather than on phi_nodes
change. And move the temporary bit vectors to scoped arena.

And write a few tests while at it.

A parallel move resolver will be needed for performing multiple moves

The arm backend clone is changed to produce A64 code. At the moment
this backend can only compile simple methods (both leaf and non-leaf).

Most of the work on the assembler (assembler_arm64.cc) has been done.
Some work on the LIR generation layer (functions such as OpRegRegImm
& friends) is still necessary. The register allocator still needs to
be adapted to the A64 instruction set (it is mostly unchanged from
the arm backend). Offsets for helpers in gen_invoke.cc still need to
be changed to work on 64-bit.

754ddad084ccb610d0cf486f6131bdc69bae5bc6 19-Feb-2014 Dave Allison <dallison@google.com> Use trampolines for calls to helpers

This is an ARM specific optimization to the compiler
that uses trampoline islands to make calls to runtime
helper functions. The intention is to reduce the size
of the generated code (by 2 bytes per call) without
affecting performance.

By default this is on when generating an OAT file. It is
off when compiling to memory.

To switch this off in dex2oat, use the command line option:
--no-helper-trampolines

Enhances disassembler to print the trampoline entry on the
BL instruction like this:

0xb6a850c0: f7ffff9e bl -196 (0xb6a85000) ; pTestSuspend

The patch adds a Middle-End pass system and normalizes the current
passes into the pass framework.

Passes have:
- A start, work, and end functions.
- A gate to determine to apply the pass.
- Can provide a CFG dump folder.

mir_dataflow.cc, mir_graph.cc, mir_optimization.cc, ssa_transformation.cc:
- Changed due to moving code into bb_optimizations.cc.
- Moved certain functions from private to public due to needed from the passes.

pass.cc, pass.h:
- Pass base class

pass_driver.cc, pass_driver.h:
- The pass driver implementation.

frontend.cc:
- Replace the function calls to the passes with the pass driver.

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.

The DexFileToMethodInlinerMap dependency on CompilerDriver
and its instruction set makes it impossible to implement
verification-time checking for methods we want to inline.
Therefore, we get rid of the platform-specific method
inliners and rely on the backend's existing ability to
recognize when it can actually emit an intrinsic function.

Bug 6961405.
Don't inflate monitors for Notify and NotifyAll.
Tidy lock word, handle recursive lock case alongside unlocked case and move
assembly out of line (except for ARM quick). Also handle null in out-of-line
assembly as the test is quick and the enter/exit code is already a safepoint.
To gain ownership of a monitor on behalf of another thread, monitor contenders
must not hold the monitor_lock_, so they wait on a condition variable.
Reduce size of per mutex contention log.
Be consistent in calling thin lock thread ids just thread ids.
Fix potential thread death races caused by the use of FindThreadByThreadId,
make it invariant that returned threads are either self or suspended now.

Code size reduction on ARM boot.oat 0.2%.
Old nexus 7 speedup 0.25%, new nexus 7 speedup 1.4%, nexus 10 speedup 2.24%,
nexus 4 speedup 2.09% on DeltaBlue.

ee17e0aa4d24deb11c1766bfcc6a864519df1c1e 31-Jul-2013 buzbee <buzbee@google.com> 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.
