Sterling Augustine 9ecccc5512 Implement dwarf5 range lists. 
This is a big change. dwarf5 range lists are quite a bit more complicated
than dwarf 4 range lists, both in the contextual information required, and
in their own representation and interpretation.

The big design choice here is how to pass the CU information all the
way down to the reader. I chose a structure, because otherwise the
parameter list gets very long and error prone (and has to be passed
down several levels). This structure could be made a parto of the CU
context itself, or the range handler, so it wouldn't have to be
separately assembled at range-list read time, but both of those
solutions get even more invasive, and harder to follow.

I've tried to figure out how to break this into smaller changes, but it
affects nearly everything that has to do with a compilation unit's
own addresses and when decisions must be made about how to read them.
Dependency injection will do that to you.

It does add tests for range list reading, which did not exist before.

Breakpad

Breakpad is a set of client and server components which implement a crash-reporting system.

Getting started (from master)

  1. First, download depot_tools and ensure that they’re in your PATH.

  2. Create a new directory for checking out the source code (it must be named breakpad).

    mkdir breakpad && cd breakpad

  3. Run the fetch tool from depot_tools to download all the source repos.

    fetch breakpad
cd src

  4. Build the source.

    ./configure && make

    You can also cd to another directory and run configure from there to build outside the source tree.

    This will build the processor tools (src/processor/minidump_stackwalk, src/processor/minidump_dump, etc), and when building on Linux it will also build the client libraries and some tools (src/tools/linux/dump_syms/dump_syms, src/tools/linux/md2core/minidump-2-core, etc).

  5. Optionally, run tests.

    make check

  6. Optionally, install the built libraries

    make install

If you need to reconfigure your build be sure to run make distclean first.

To update an existing checkout to a newer revision, you can git pull as usual, but then you should run gclient sync to ensure that the dependent repos are up-to-date.

To request change review

  1. Follow the steps above to get the source and build it.

  2. Make changes. Build and test your changes. For core code like processor use methods above. For linux/mac/windows, there are test targets in each project file.

  3. Commit your changes to your local repo and upload them to the server. http://dev.chromium.org/developers/contributing-code e.g. git commit ... && git cl upload ... You will be prompted for credential and a description.

  4. At https://chromium-review.googlesource.com/ you'll find your issue listed; click on it, then “Add reviewer”, and enter in the code reviewer. Depending on your settings, you may not see an email, but the reviewer has been notified with google-breakpad-dev@googlegroups.com always CC’d.
