clang 15 now warns: 46 65.20 fedora:rawhide : FAIL clang version 15.0.0 (Fedora 15.0.0-3.fc38) util/parse-events-bison.c:1401:9: error: variable 'parse_events_nerrs' set but not used [-Werror,-Wunused-but-set-variable] int yynerrs = 0; ^ #define yynerrs parse_events_nerrs ^ 1 error generated. make[3]: *** [/git/perf-6.0.0-rc7/tools/build/Makefile.build:139: util] Error 2 Just ignore one more compiler warning for the bison generated C code. Committer notes: Older clangs don't know about -Wunused-but-set-variable, so we need to add -Wno-unknown-warning-option to avoid this: 37 44.92 fedora:32 : FAIL clang version 10.0.1 (Fedora 10.0.1-3.fc32) error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'?
