How can I use a preprocessor #if expression to tell if a machine is big-endian or little-endian?
Infrequently Asked Questions in comp.lang.cI've got this tricky processing I want to do at compile time and I can't figure out a way to get cpp to do it.
Related QuestionsThe C Language FAQYou probably can't. (Preprocessor arithmetic uses only long ints, and there is no concept of addressing.) Are you sure you need to know the machine's endianness explicitly? Usually it's better to write code which doesn't care. I've got this tricky processing I want to do at compile time and I can't figure out a way to get cpp to do it. cpp is not intended as a general-purpose preprocessor.Related Questions
How can I determine whether a machine's byte order is big-endian or little-endian?
System DependenciesHow can I access an interrupt vector located at the machine's location 0? If I set a pointer to 0, the compiler might translate it to some nonzero internal null pointer value. Some systems also provide a family of spawn routines which accomplish approximately the same thing. system is more ''portable'' in that it is required under the ANSI C Standard, although the interpretation of the command string--its syntax and the set of commands accepted--will obviously vary tremendously.
Related QuestionsIs OCP big or little endian?
OCP-IP - General TechnicalOCP is little endian with respect to bit numbering, but it is largely endian-neutral with respect to addressing. Only whole words are addressed, and byte lane enables are provided for each byte within a word. So address bits are not directly associated with byte lanes. This makes adaptation to either big or little endian cores simpler. The newer OCP 2.0 specification extends the notion of endian neutrality even farther.
