Subject[PATCH] perf tools: Fix build dependency of perf python extension
Date
The perf python extention (perf.so) file lacks its dependencies in the
Makefile so that it cannot be refreshed if one of source files it depends
is changed. Fix it by putting them in a separate file and processing it in
both of Makefile and setup.py.

Hello, Arnaldo.

This is my attempt to fix the problem you said. I used a separate file to
track the dependency and it was used by both Makefile and setup.py. It
seemed work well for me. Please let me know if I missed something.

Thanks.
