/* The code in sections .init and .fini is supposed to be a single
regular function. The function in .init is called directly from
start in crt1.asm. The function in .fini is atexit()ed in crt1.asm

crti.asm contributes the prologue of a function to these sections,

crti.o before any other object files that might add code to .init
