kbuild: clean .tmp_* pattern by make cleanChange 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 toavoid the removal by "make clean".Signed-off-by: Masahiro Yamada Tested-by: Sedat Dilek # LLVM-14 (x86-64) List of files: /linux-6.15/scripts/objdiff

65ba6fa4 - scripts: objdiff: Ignore debug info when comparing

Thu, 16 Feb 2017 21:18:20 +0000

scripts: objdiff: Ignore debug info when comparingIf the kernel is configured to be built with debug symbols, orhas bug tables, comparing files may not work if line numberschange. This makes comparing object files with these optionsharder to do. Let's strip out the debug info and drop the__bug_table here so that we don't see false positives. There maybe other things to drop later, and it may be architecturespecific, but this works for me with my ARM64 build.Signed-off-by: Stephen Boyd Reviewed-by: Jason Cooper Signed-off-by: Masahiro Yamada List of files: /linux-6.15/scripts/objdiff

8b5d0f20 - scripts: objdiff: change the extension of disassembly from .o to .dis

Mon, 09 Jun 2014 02:16:38 +0000

scripts: objdiff: change the extension of disassembly from .o to .disPrior 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.Signed-off-by: Masahiro Yamada Acked-by: Jason Cooper Signed-off-by: Michal Marek List of files: /linux-6.15/scripts/objdiff

Mon, 09 Jun 2014 02:16:34 +0000

scripts: objdiff: get the path to .tmp_objdiff more simplyThis commit is a minor refactoring.Temporary files for objdiff are stored in .tmp_objdiff directorywhich is located at the top directory.To get the path to this directory, SRCTREE=`git rev-parse --show-toplevel` TMPD=$SRCTREE/.tmp_objdiffseems easier to understand than GIT_DIR=`git rev-parse --git-dir` TMPD=${GIT_DIR%git}tmp_objdiffBesides, 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 List of files: /linux-6.15/scripts/objdiff

79192ca8 - scripts: objdiff: detect object code changes between two commits

Mon, 07 Apr 2014 18:30:29 +0000

scripts: objdiff: detect object code changes between two commitsobjdiff is useful when doing large code cleanups. For example, whenremoving checkpatch warnings and errors from new drivers in the stagingtree.objdiff can be used in conjunction with a git rebase to confirm thateach commit made no changes to the resulting object code. It has thesame return values as diff(1).This was written specifically to support adding the skein and threefishcryto drivers to the staging tree. I needed a programmatic way toconfirm that commits changing >90% of the lines didn't inadvertentlychange the code.Temporary files (objdump output) are stored in /path/to/linux/.tmp_objdiff'make mrproper' will remove this directory.Signed-off-by: Jason Cooper Signed-off-by: Michal Marek List of files: /linux-6.15/scripts/objdiff
