perf parse-events: Ignore clang 15 warning about variable set but unused in bison produced code
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'? [-Werror,-Wunknown-warning-option]
