[Ltrace-devel] [PATCH] Early support for libdl in ltrace

[Joe Damato]

Hi -

No responses =C but I'll keep sending patches until some one says "stop" =]

I've attached a cleaned up patch of libdl support, this works (and was
tested) on both x86 AND x86_64. This still has the caveats listed
below (namely doesn't know about dlsym events that occur after it
attaches), but the code has been split into architecture dependent
subdirs, and is quite a bit cleaner than the previous iterations.

I hope to be done with full libdl support in the next few days, time permitting.

As always questions, comments, suggestions, gripes, and grievances are
all welcome.

Thanks,
Joe
