Test: unit test
Test: Ran with a tombstone file as parameter.
Test: Ran pasting in stack to stdin.

The path where the tests are uploaded by atest differs from the
path to unstripped binaries in the out directory. As a result,
the script can't symbolize the parts of the stack trace that
correspond to code in the test binary. Add a fixup to use the
correct path.
Test: Used the script on example crashes in framework and vendor
device tests - appears to work and give correct line numbers.

Replace all references to gcc tools with llvm tools. This change still
uses c++filt until llvm-cxxfilt is put in the prebuilts.
Test: Ran a backtrace through this script and the old script and verified
Test: no major differences.
Test: Ran unittests for symbol.py and stack_core.py.

When seeing a line like:
#01 pc 0012ea14 /system/lib/libart.so!libart.so (offset 0x134000)
Treat it like this line instead:
#01 pc 0012ea14 /system/lib/libart.so
This will allow the symbolizer to properly figure out the line numbers.

Test: Ran lines with xxx.so!xxx.so lines and verified that they decode.

If the value_line regex matches, and the symbol file happens to exist
as a directory, we'd call addr2line and crash. Fix this so that calling
addr2line on a directory doesn't happen.
There isn't an easy way to test this, but I added a single new unit test. The
real test was to use a tombstone file that used to crash, but no longer crashes.
Test: Wrote new unit test, ran over a tombstone file that used to crash.

Manually count input stack trace lines that match the regexps instead of
relying on the output of addr2line. Random changes to the libraries
listed in the test case could cause addr2line to land in an inlined
function and print multiple lines for each input stack frame.

The previous code used unzip to get the offsets of the files in
the zip file. This was an estimate, and it turns out to be wrong
in many cases. Replace that with zipinfo -v which gives the exact
offset of the files in the zip.
Also update the tmp files so that they are in a dictionary of their
own by apk, instead of embedded in the offset list.

The CallStack function prints stacks to the log. Unfortunately, our
stack script defaults to arm, so if the data is actually arm64, we'll
do nothing. Modify the script to parse the input trying to determine
the abi before processing the rest of the lines. At the very least,
we'll be able to correctly choose between arm and arm64.
The only downside, is that, the old method could take dumps from different
abis, but no one I know does this.

Some of the map names have spaces in them, but only the ones that look
like:
[anon:atexit handlers]
So allow spaces between a [ and a ].

The dlopen of a shared library within an apk is not handled by
the stack tool. Modify to understand and search through the apk to
find the shared library associated with the offset. Then unzip
that shared library to use as the target of addr2line.

Add trace parsing for sanitizer output. The output is different
from debuggerd output (and we do not have control over it). Use
two separate regexes and factor out the parsing into a method
returning a tuple of data.
Note: as we have no control over the prologue of the dump, we
cannot change it to include information like the ABI. Thus, this
functionality only works in a lunched tree, where the tool
implicitly uses the symbols directory.

This is needed by the internal stack decoding website, which
will be pulling symbols from the build servers anyway (so doesn't
need to be correctly lunched).

Left the default symbol.ARCH value intact and changed stack_core instead
so that it will assume the ABI is arm until it sees an ABI line. This
allows compatibility for people who are used to pasting portions of a
tombstone instead of the whole thing (assuming said tombstone is arm)
while additionally supporting other architectures if a whole tombstone
is pasted in.

Also take into account the fact that the arm pcsr register is the
fifth entry on its line, so the stack tool previously stripped that
off.

x86 uses the x86_64 toolchain. There's no separate 32-bit toolchain.
I started to refactor so we could add FindToolchain tests, but that doesn't
work because FindToolchain depends on environment variables set up by 'lunch'.

The value corresponds to whether or not the line has matched one of the
detected formats (registers, header, backtrace, etc.) and can be used to
identify what logcat lines don't correspond to one of these formats.

Every architecture was at least slightly wrong. Rather than try to
tune the heuristics, let's just keep lists of all the registers.
Also start adding some unit tests.

This includes the fairly large change of refactoring stack_core.py into
a class so that its behavior is compatible with adbs. Additionally, if
the ABI line does not come before lines that require it to determine
proper widths (registers, stack), then it will assume that the ABI is
32 bit and not 64.
