#135120 - how do you know that ? Responding to: ???'s previous message |
but in this SPECIAL case, it will work.
there is absolutely no reason that main() would be called. Yes, it is a 'function' but it is acessed from the startup code and Startup.a51 does jump in and jump out, so why should that 'unknown stuff' startup jumps to call main instead of continuing jumping??? Thus, by a reasonable assumption the ret at the end of main (that is only there because main is handles by the compiler as a function - why make an exception when none needed) will jump out in the blue younder since there is no return address pushed upon the stack.
