Hello, I would like to know if there exists some macros for the compiler.
Like the following:
aarch64
arm
i486
And I would like to know the endianess of the machine architectures. I guess all are little endian?
Is there a macro for 32bit and 64bit and a BYTE_ORDER macro?
Yes, all are little-endian… but you could use the __BYTE_ORDER__ macro for that.
You can use __i386__, __x86_64__ and __aarch64__… or maybe the size of the size type is more relevant for your needs.
nothing SFOS specific about it…
Yes, the compiler is gcc, so the gcc documentation should provide all the necessary information: Predefined Macros (The C Preprocessor)
