2190d929695c31ad7195e2c366f4102836a7d827 23-Mar-2016 Alex Light <allight@google.com> Add support for Dex version 37 in Runtime.

We are skipping version 36 of the dex file format due to a bug in
Dalvik dating back to ICS where dex files marked version 036 would
erroneously be accepted.

Follow-up to 9bdf108885a27ba05fae8501725649574d7c491b. Make sure
that dex files from the oat writer are verified with the dex file
verifier.

9bdf108885a27ba05fae8501725649574d7c491b 21-Jan-2016 Vladimir Marko <vmarko@google.com> Revert "Revert "Write dex files to oat file early.""

This reverts commit 919f5536182890d2e03f59b961acf8f7c836ff61.

Fix linker error (Mac build):
Replace inline definition of art::ZipArchive::~ZipArchive()
with an out-of-line definition in zip_archive.cc to avoid
direct reference to CloseArchive() from libart-compiler due
to inlining. Note that libart is linked against -lziparchive
but libart-compiler is not.

This reverts commit 625a64aad13905d8a2454bf3cc0e874487b110d5.

Breaks the Mac build:

Undefined symbols for architecture i386:
"_CloseArchive", referenced from:
... in oat_writer.o
ld: symbol(s) not found for architecture i386

625a64aad13905d8a2454bf3cc0e874487b110d5 26-Nov-2015 Vladimir Marko <vmarko@google.com> Write dex files to oat file early.

Write dex files to oat file before we actually open and
verify them. Instead, open and verify the copies from the
oat file and use these. This way, in the most common case
of zipped dex files, we have mmapped dex files instead of
inflated dex files. That reduces the number of dirty pages
used by dex2oat.

Reading /proc/self/statm after we write the oat file for
a compilation of a certain large app on Nexus 5 AOSP build
with -j1, three attempts before and after this CL gave
before: 346061 189462 6269 26 0 140723 0
346189 189450 6269 26 0 140851 0

346186 185822 23040 27 0 140468 0
These values are in pages (4KiB), so while the "size"
(=VmSize) is essentially unchanged, the "resident" (=VmRSS)
is over 14MiB less and the "shared" (i.e. backed by a file)
is 65.5MiB more. That is, the amount of dirty non-pageable
memory used is reduced by about 80MiB.

The oat file format has changed slightly, the class offset
table has been moved from the OatDexFile to its own section.
This actually fixes the alignment of these offsets as they
could have been unaligned previously, yet accessed as normal
with significant performance impact if the kernel has to
emulate the unaligned access (say, mips).

41b175aba41c9365a1c53b8a1afbd17129c87c14 19-May-2015 Vladimir Marko <vmarko@google.com> ART: Clean up arm64 kNumberOfXRegisters usage.

Avoid undefined behavior for arm64 stemming from 1u << 32 in
loops with upper bound kNumberOfXRegisters.

Create iterators for enumerating bits in an integer either
from high to low or from low to high and use them for
<arch>Context::FillCalleeSaves() on all architectures.

Refactor runtime/utils.{h,cc} by moving all bit-fiddling
functions to runtime/base/bit_utils.{h,cc} (together with
the new bit iterators) and all time-related functions to
runtime/base/time_utils.{h,cc}. Improve test coverage and
fix some corner cases for the bit-fiddling functions.

as ref and thus 32bit.

Use method signatures, field types and types embedded in dex
insns for type inference. Perform the type inference in two
phases, first a simple pass that records all types implied
by individual insns, and then an iterative pass to propagate
those types further via phi, move, if-cc and aget/aput insns.
