This is the right thing 71476fee5SMasahiro Yamada# to do. However, people usually do 'git pull', 'git bisect', etc. without 81476fee5SMasahiro Yamada# running 'make clean'. Then, the stale generated files are left over, often 91476fee5SMasahiro Yamada# causing build issues. 101476fee5SMasahiro Yamada# 111476fee5SMasahiro Yamada# Also, 'git status' shows such stale build artifacts as untracked files. 121476fee5SMasahiro Yamada# What is worse, some people send a wrong patch to get them back to .gitignore 131476fee5SMasahiro Yamada# without checking the commit history. 141476fee5SMasahiro Yamada# 151476fee5SMasahiro Yamada# So, when you (re)move generated files, please move the cleaning rules from 161476fee5SMasahiro Yamada# the Makefile to this script.
