This change removes the -w from flex and bison targets. To avoid implicit declarations header files are declared as targets and included. Tested with GCC 9.3.0 and clang 9.0.1. v2. predicates disabling the warnings on more recent bison and flex versions (3.5.3 and 2.6.4 respectively). An alternative would be to disabled a large number of warnings to cover the warnings generated in older distributions: flex_flags := -Wno-switch-enum -Wno-switch-default -Wno-unused-function \ -Wno-redundant-decls -Wno-sign-compare -Wno-unused-parameter \ -Wno-missing-prototypes -Wno-misleading-indentation bison_flags := -DYYENABLE_NLS=0 -Wno-unused-parameter -Wno-nested-externs \ -Wno-implicit-function-declaration -Wno-switch-enum Previously posted as a single change: https://lore.kernel.org/lkml/20200609234344.3795-2-irogers@google.com/ Ian Rogers (10): perf parse-events: Use automatic variable for flex input perf parse-events: Use automatic variable for yacc input perf pmu: Add bison debug build flag perf pmu: Add flex debug build flag perf parse-events: Declare flex header file output perf parse-events: Declare bison header file output perf parse-events: Disable a subset of flex warnings perf expr: Avoid implicit lex function declaration perf parse-events: Avoid implicit lex function declaration perf parse-events: Disable a subset of bison warnings tools/perf/util/Build | 62 +++++++++++++++++++++++----------- tools/perf/util/expr.y | 2 ++ tools/perf/util/parse-events.y | 1 + 3 files changed, 46 insertions(+), 19 deletions(-) -- 2.27.0.111.gc72c7da667-goog
