    10         @author         Jonathan 'Wolf' Rentzsch: <http://rentzsch.com>
    11        
    12         This package, coded in C to the Mach API, allows you to override ("patch")
    13         program- and system-supplied functions at runtime. You can fully replace
    14         functions with your implementations, or merely head- or tail-patch the
    15         original implementations.
    16        
    17         Use it by #include'ing mach_override.h from your .c, .m or .mm file(s).
    18        
    19         @todo   Discontinue use of Carbon's MakeDataExecutable() and
    20                         CompareAndSwap() calls and start using the Mach equivalents, if they
    21                         exist. If they don't, write them and roll them in. That way, this
    22                         code will be pure Mach, which will make it easier to use everywhere.
    23                         Update: MakeDataExecutable() has been replaced by
    24                         msync(MS_INVALIDATE). There is an OSCompareAndSwap in libkern, but
    25                         I'm currently unsure if I can link against it. May have to roll in
    26                         my own version...
    27         @todo   Stop using an entire 4K high-allocated VM page per 28-byte escape
    28                         branch island. Done right, this will dramatically speed up escape
    29                         island allocations when they number over 250. Then again, if you're
    30                         overriding more than 250 functions, maybe speed isn't your main
    31                         concern...
    32         @todo   Add detection of: b, bl, bla, bc, bcl, bcla, bcctrl, bclrl
    33                         first-instructions. Initially, we should refuse to override
    34                         functions beginning with these instructions. Eventually, we should
    35                         dynamically rewrite them to make them position-independent.
    36         @todo   Write mach_unoverride(), which would remove an override placed on a
    37                         function. Must be multiple-override aware, which means an almost
    38                         complete rewrite under the covers, because the target address can't
    39                         be spread across two load instructions like it is now since it will
    40                         need to be atomically updatable.
    41         @todo   Add non-rentry variants of overrides to test_mach_override.
