Hi all, After merging the perf tree, today's linux-next build (native perf) failed like this: In file included from /usr/include/stdio.h:866, from /home/sfr/next/next/tools/perf/util/branch.h:9, from util/branch.c:2: In function 'fprintf', inlined from 'branch_type_stat_display' at util/branch.c:152:4: /usr/include/powerpc64le-linux-gnu/bits/stdio2.h:105:10: error: '%8s' directive argument is null [-Werror=format-overflow=] 105 | return __fprintf_chk (__stream, __USE_FORTIFY_LEVEL - 1, __fmt, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 106 | __va_arg_pack ()); | ~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Presumably caused by commit 9781e500dcb8 ("perf branch: Extend branch type classification") "native" here is PowerPC64 LE. $ gcc --version gcc (Debian 11.2.0-10) 11.2.0 I have used the perf tree from next-20220830 for today. -- Cheers, Stephen Rothwell
