    more sensical approach to analysing this program, e.g. as employed by a human, would be to see that NeverCalled() is the only function that can write Do It is not only non-trivial …

    The function pointer is static. But the function that mutates it, NeverCalled, is not. One can still indirectly change that function pointer.

    This is probably why there is not a proof yet, since the truth is undesirable. You are presenting an explanation to a false observation.

    Compile with -fno-frame-pointer and you won't see those code. It's for debugger.

    A lot of dota's mechanics is designed with the assumption that the player is human -- e.g. skills that can be programmed to be released perfectly but are hard for a human (even pro…

    Except WebAsm is language independent and reuses DOM (indirectly through javascript).

    Labelling an operation -- number of steps of which upper-bounded by 6 -- "effectively constant" is different from considering any real world algorithm with bounded input size. Call…

    It blocks other interprocedural optimization such inlining and interprocedural const prop.

    Comment #14627820

    It's unsafe for a compiler to do this in general (i.e. without annotations) because it can't determine dependencies that are external to the program -- e.g. `one=get(); two=get()`.…

    Register allocation in general is np-complete[1][2]. Having polynomial-time coloring algorithm for SSA doesn't make the allocation optimal -- you still need to "lower" the SSA to p…
