linux.git/arch/powerpc/tools, branch v5.10 Linux kernel source tree powerpc/tools: Remove 90 line limit in checkpatch script 2020-09-08T12:57:11+00:00 Russell Currey ruscur@russell.cc 2020-08-28T02:05:42+00:00 0fb4871bcc8997acbb8edf14b301fc150101d6c0 As of commit bdc48fa11e46, scripts/checkpatch.pl now has a default line length warning of 100 characters. The powerpc wrapper script was using a length of 90 instead of 80 in order to make checkpatch less restrictive, but now it's making it more restrictive instead. I think it makes sense to just use the default value now.

powerpc: unrel_branch_check.sh: enable the use of llvm-objdump v9, 10 or 11 2020-09-02T01:00:22+00:00 Stephen Rothwell sfr@canb.auug.org.au 2020-08-12T08:10:36+00:00 6b1992bcdee8b86a74362192d4d8906731918bcc Currently, using llvm-objtool, this script just silently succeeds without actually do the intended checking. So this updates it to work properly. Firstly, llvm-objdump does not add target symbol names to the end of branches in its asm output, so we have to drop the branch to __start_initialization_multiplatform using its address. Secondly, v9 and 10 specify branch targets as .+<offset>, so we convert those to actual addresses. Thirdly, v10 and 11 error out on a vmlinux if given the -R option complaining that it is "not a dynamic object". The -R does not make any difference to the asm output, so remove it. Lastly, v11 produces asm that is very similar to Gnu objtool (at least as far as branches are concerned), so no further changes are necessary to make it work.
