WebJan 24, 2024 · A standard C implementation could pack these bit fields into two 32-bit integers. It might store tricky_bits.may_straddle as 16 bits in one 32-bit integer and 14 bits in the next 32-bit integer. The Windows ABI convention packs bit fields into single storage integers, and doesn't straddle storage units. Web50 minutes ago · In my recent post about endianness, I was told that one should unionize the types because not doing so can cause UB.. I have found talk of this in other posts as well.. In this post, "strict pointer aliasing violation" is mentioned as a problem when not using unions.. In this post, it is mentioned that 8-bit types don't have to have the same memory …
