While debugging why the dynamic loader is just not working for me on sparc, I
stumbled across this little gem:
Near the end of ldso/ldso/dl-startup.c we have the only user of the START()
macro:
#ifndef START
return _dl_elf_main;
#else
START();
#endif
Only three architectures actually #define this macro: frv, bfin, and avr32.
The last of which does:
./avr32/dl-startup.h:#define START() return _dl_elf_main;
So it's #defining the macro to do what the absence of the macro would do.
Why?
