However, people usually do 'git pull', 'git bisect', etc. without 8# running 'make clean'. Then, the stale generated files are left over, often 9# causing build issues. 10# 11# Also, 'git status' shows such stale build artifacts as untracked files. 12# What is worse, some people send a wrong patch to get them back to .gitignore 13# without checking the commit history. 14# 15# So, when you (re)move generated files, please move the cleaning rules from 16# the Makefile to this script. This is run before Kbuild starts building 17# anything, so people will not be annoyed by such garbage files. 18# 19# This script is not intended to grow endlessly. Rather, it is a temporary scrap 20# yard. Stale files stay in this file for a while (for some release cycles?), 21# then will be really dead and removed from the code base entirely. 22 23# These were previously generated source files. When you are building the kernel 24# with O=, make sure to remove the stale files in the output tree. Otherwise, 25# the build system wrongly compiles the stale ones. 26if [ -n "${building_out_of_srctree}" ]; then 27 for f in fdt_rw.c fdt_ro.c fdt_wip.c fdt.c 28 do 29 rm -f arch/arm/boot/compressed/${f} 30 done 31fi 32
