Hi, I can't get opt to list (in -help) passes that I load using -load. I see in the list archives that a similar problem has been brought up before but I didn't see whether it was resolved. Also, this is on Mac OS X, and the previous question was about Linux. This problem happens with the Hello pass, so I'll use that to illustrate. I'm using LLVM 1.2. The plugin loads with no

Unfortunately it's not that easy, although I'd love to fix it if I can figure out how. OS X 10.3 does have dlfcn.h and dlopen() - for 10.3, they added the dlcompat library that uses the OS X NSLink* stuff to support dlopen and dlsym. configure seems to pick that up fine. It seems like the code that's there already should work fine, so I'm not sure where else to look. I'm

OK, seems like I've got some more looking to do. From what I can find, the only difference with OS X and dynamic libraries is that you can't depend on the order of calling static constructors, but not that you can't depend on them getting called. :) If I find that library handling in LLVM needs changes to work with OS X, I'll send a patch.

Solved. Short version: You don't need to change DynamicLinker.cpp at all. dlopen() should just work, except that the defaults for libtool are to produce the wrong kind of shared object. On OS X, libtool needs to be passed the -module option to create dlopen-able objects: % diff Makefile.rules.old Makefile.rules 326c326 < Link := $(LIBTOOL) --mode=link $(CXX) --- > Link
