I think this is actually a false positive, look at the definition of BWN_DMA_BIT_MASK: #define BWN_DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1)) It wouldn't shift by 64 bits. -- Lubos Boucek ---------------------------------------- Bug #3023: sys/dev/netif/bwn/bwn/if_bwn.c: 2 * strange bitmasks ? http://bugs.dragonflybsd.org/issues/3023#change-13257 * Author: dcb * Status: New * Priority: Normal * Assignee: * Category: Driver * Target version: ---------------------------------------- 1. sys/dev/netif/bwn/bwn/if_bwn.c:2646]: (error) Shifting 64-bit value by 64 bits is undefined behaviour Source code is return (BWN_DMA_BIT_MASK(64)); Bitmasks are conventionally numbered 0 .. 63. 2. sys/dev/netif/bwn/bwn/if_bwn.c:2664]: (error) Shifting 64-bit value by 64 bits is undefined behaviour Source code is if (dmamask == BWN_DMA_BIT_MASK(64)) -- You have received this notification because you have either subscribed to it, or are involved in it.
