* Thoroughly rehack the dynamic linking mechanisms on Win32. The Win32Chris Lattner2004-05-281-16/+41
| | | | | | | | | | | | dynamic linker does not automatically search libraries when looking up symbols with GetProcAddress. Because of this we have to emulate it. The only detail is that there doesn't seem to be a way to enumerate the libraries loaded, so we have a gross hack (tm). This make the JIT functional on win32 under cygwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13887 91177308-0d34-0410-b5e6-96231b3b80d8

It doesn't really make sense for the new one to do so, so we just make the client do it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13877 91177308-0d34-0410-b5e6-96231b3b80d8
