Hi all! I just found the line in the subject in our jenkinsbuild log in both amd64 and i386 case (we don't modified these files): http://nyi-01.build.hardenedbsd.org:8180/jenkins/job/HardenedBSD-master-i386/56/console http://nyi-01.build.hardenedbsd.org:8180/jenkins/job/HardenedBSD-master-amd64/58/consoleFull And more similar lines: WARNING: kern_pmc.c: enum pmc_event has too many values: 1930 > 1023 WARNING: kern_rwlock.c: enum pmc_event has too many values: 1930 > 1023 WARNING: kern_sx.c: enum pmc_event has too many values: 1930 > 1023 WARNING: kern_clock.c: enum pmc_event has too many values: 1930 > 1023 WARNING: kern_mutex.c: enum pmc_event has too many values: 1930 > 1023 WARNING: trap.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_soft.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_intel.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_amd.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_tsc.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_x86.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_logging.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_piv.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_uncore.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_core.c: enum pmc_event has too many values: 1930 > 1023 WARNING: hwpmc_mod.c: enum pmc_event has too many values: 1930 > 1023 WARNING: kern_lock.c: enum pmc_event has too many values: 1930 > 1023 and some other hwpmc related warnings too: --- kern_pmc.o --- /jenkins/workspace/HardenedBSD-master-amd64/sys/kern/kern_pmc.c:290:32: warning: comparison of constant 131072 with expression of type 'enum pmc_event' is always false [-Wtautological-constant-out-of-range-compare] KASSERT(ps->ps_ev.pm_ev_code >= PMC_EV_SOFT_FIRST && ~~~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~~~~~~~ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/systm.h:84:24: note: expanded from macro 'KASSERT' if (__predict_false(!(exp))) \ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/cdefs.h:453:51: note: expanded from macro '__predict_false' #define __predict_false(exp) __builtin_expect((exp), 0) ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/kern/kern_pmc.c:291:28: warning: comparison of constant 135167 with expression of type 'enum pmc_event' is always true [-Wtautological-constant-out-of-range-compare] ps->ps_ev.pm_ev_code <= PMC_EV_SOFT_LAST, ~~~~~~~~~~~~~~~~~~~~ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/systm.h:84:24: note: expanded from macro 'KASSERT' if (__predict_false(!(exp))) \ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/cdefs.h:453:51: note: expanded from macro '__predict_false' #define __predict_false(exp) __builtin_expect((exp), 0) ^ --- kern_prot.o --- --- kern_pmc.o --- /jenkins/workspace/HardenedBSD-master-amd64/sys/kern/kern_pmc.c:307:13: warning: comparison of constant 131072 with expression of type 'enum pmc_event' is always false [-Wtautological-constant-out-of-range-compare] KASSERT(ev >= PMC_EV_SOFT_FIRST && ~~ ^ ~~~~~~~~~~~~~~~~~ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/systm.h:84:24: note: expanded from macro 'KASSERT' if (__predict_false(!(exp))) \ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/cdefs.h:453:51: note: expanded from macro '__predict_false' #define __predict_false(exp) __builtin_expect((exp), 0) ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/kern/kern_pmc.c:308:9: warning: comparison of constant 135167 with expression of type 'enum pmc_event' is always true [-Wtautological-constant-out-of-range-compare] ev <= PMC_EV_SOFT_LAST, ~~ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/systm.h:84:24: note: expanded from macro 'KASSERT' if (__predict_false(!(exp))) \ ^ /jenkins/workspace/HardenedBSD-master-amd64/sys/sys/cdefs.h:453:51: note: expanded from macro '__predict_false' #define __predict_false(exp) __builtin_expect((exp), 0) ^
