Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Johnny Chen 8831e18b17 Make 'run-until-faulted.py' script more interesting by modifying the example main.c program
to seg fault randomly instead of deterministically.

Example:

[15:10:43] johnny:/Volumes/data/lldb/svn/trunk/utils/test $ clang -g main.c
[15:10:46] johnny:/Volumes/data/lldb/svn/trunk/utils/test $ ./run-until-faulted.py -l $PWD/../../build/Debug/lldb -e a.out
lldb command: /Volumes/data/lldb/svn/trunk/utils/test/../../build/Debug/lldb

Johnny Chen 511e8c0d36 Add a Python script which launches a program from within lldb and loop until the
process stops for some reason.  main.c (compiled into a.out) is used as an example in
the README-run-until-faulted file.
