c - Predefined macro to distinguish arm-none-eabi-gcc from gcc -


i building own library supposed work both on arm mbed , on linux platforms. if target arm mbed, library needs cross-compiled arm-none-eabi-gcc while if target platform linux, library needs compiled gcc. there predefined compiler macro allow me determine compiler invoked compile library? note raspberry pi has arm cpu needs supported cannot use arch macros.

as suggested comments , link: https://gcc.gnu.org/onlinedocs/cpp/system-specific-predefined-macros.html#system-specific-predefined-macros, macro __unix__ defined gcc not arm-none-eabi-gcc. if has better answer, please post it.
