In computing, endianness is the order or sequence of bytes of a word of digital data in computer memory. Endianness is primarily expressed as big-endian (BE) or little-endian (LE). A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest. A little-endian system, in contrast, stores the least-significant byte at the smallest address.

How exactly does __attribute__((constructor)) work?
GCC __attribute__((constructor)) is called before object constructor
C++ static initialization vs __attribute__((constructor))
__attribute__((constructor[(priority)])) function attribute
__attribute__((constructor(priority))) function attribute
__attribute__((init_priority(X))) in GCC
__attribute__((weak)) and static libraries
void noOsSystickHandler() { } // empty
void osSystickHandler() __attribute__((weak, alias("noOsSystickHandler")));
