*** 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.

""" Copies the build output of a custom python interpreter to a directory
|
|
structure that mirrors that of an official Python distribution.
|
|
|
|
--------------------------------------------------------------------------
|
|
File: install_custom_python.py
|
|
|
|
Overview: Most users build LLDB by linking against the standard
|
|
Python distribution installed on their system. Occasionally
|
|
a user may want to build their own version of Python, and on
|
|
platforms such as Windows this is a hard requirement. This
|
|
script will take the build output of a custom interpreter and
|
|
install it into a canonical structure that mirrors that of an
|
|
official Python distribution, thus allowing PYTHONHOME to be
|
|
set appropriately.
|
|
|

Gotchas: None.
