WebMay 25, 2024 · Only bitfields of unsigned int, singed int, and _Bool are guaranteed to be supported by all C compilers (int is allowed as well, but in the context of bitfields, int can be signed or unsigned, depending on the implementation, so there's no point in really using it). GCC supports other types as an extension. WebDec 26, 2015 · The C++ Standard sets no limits on the size of a bit-field, other than that it must be greater or equal to zero - section 9.6/1. It also says: Bit-fields are packed into some addressable allocation unit. [Note: bit-fields straddle allocation units on some machines and not on others.

The following properties of bit-fields are implementation-defined: 1. The value that results from assigning or initializing a signed bit-field with a value out of range, or from incrementing a signed bit-field past its range. 2. Everything about the actual allocation details of bit-fields within the class object 1. 1.1. … See more The type of a bit-field can only be integral or (possibly cv-qualified) enumeration type, an unnamed bit-field cannot be declared with a cv-qualified type.

So if you have a 32-bit item in the middle and 1-bit items on each side, that's 3 32-bit words to allocate and so: 12 bytes.
