*** 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.

"""

A simple bench runner which delegates to the ./dotest.py test driver to run the
|
|
benchmarks defined in the list named 'benches'.
|
|
|
|
You need to hand edit 'benches' to modify/change the command lines passed to the
|
|
test driver.
|
|
|
|
Use the following to get only the benchmark results in your terminal output:
|
|
|
|
./bench.py -e /Volumes/data/lldb/svn/regression/build/Debug/lldb -x '-F Driver::MainLoop()' 2>&1 | grep -P '^lldb.*benchmark:'
|
