kbuild: clean .tmp_* pattern by make clean

2022-06-04T21:20:57Z

Change the "make clean" rule to remove all the .tmp_* files. .tmp_objdiff is the only exception, which should be removed by "make mrproper". Rename the record directory of objdiff, .tmp_objdiff to .objdiff to avoid the removal by "make clean". Signed-off-by: Masahiro Yamada Tested-by: Sedat Dilek # LLVM-14 (x86-64)

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 199

2019-05-30T18:29:23Z

Based on 1 normalized pattern(s): licensed under the terms of the gnu gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 1 file(s).

scripts: objdiff: Ignore debug info when comparing

2017-03-11T02:13:38Z

If the kernel is configured to be built with debug symbols, or has bug tables, comparing files may not work if line numbers change. This makes comparing object files with these options harder to do. Let's strip out the debug info and drop the __bug_table here so that we don't see false positives. There may be other things to drop later, and it may be architecture specific, but this works for me with my ARM64 build.

scripts: objdiff: support directories for the augument of record command

2014-06-10T12:59:33Z

For example, $ scripts/objdiff record init drivers/usb disassembles all the objects under init and drivers/usb directories. This feature would be useful when we change various files under the specific directory. Signed-off-by: Masahiro Yamada Acked-by: Jason Cooper Signed-off-by: Michal Marek

scripts: objdiff: change the extension of disassembly from .o to .dis

2014-06-10T12:59:33Z

Prior to this commit, the command "scripts/objdiff record path/to/*.o" disassembled the given object into ".tmp_objdiff/path/to/*.o" file. The problem here is that recorded disassemblies are lost if we run "make clean" because it removes all the *.o files. Disassembled code should be dumped into *.dis instead of *.o files.

scripts: objdiff: improve path flexibility for record command

2014-06-10T12:59:33Z

Prior to this commit, scripts/objdiff expected to be run at the top directory and only the relative path of objects. This commit provides more flexibility in terms of object path: [1] scripts/objdiff can be run in any directory For example, $ scripts/objdiff record init/main.o and $ cd init; ../scripts/objdiff record main.o produce the same result. [2] Support absolute path for objects $ scripts/objdiff record /home/foo/bar/linux/init/main.o work as well. Signed-off-by: Masahiro Yamada Acked-by: Jason Cooper Signed-off-by: Michal Marek

scripts: objdiff: get the path to .tmp_objdiff more simply

2014-06-10T12:59:33Z

This commit is a minor refactoring. Temporary files for objdiff are stored in .tmp_objdiff directory which is located at the top directory. To get the path to this directory, SRCTREE=`git rev-parse --show-toplevel` TMPD=$SRCTREE/.tmp_objdiff seems easier to understand than GIT_DIR=`git rev-parse --git-dir` TMPD=${GIT_DIR%git}tmp_objdiff Besides, it is not always necessary to create .tmp_objdiff dicrectory. It should be created only for "record" command. Signed-off-by: Masahiro Yamada Acked-by: Jason Cooper Signed-off-by: Michal Marek
