static archive that can be linked against. LLDB.framework/lldb.so exports a very controlled API. Splitting the API into a static library allows other tools (debugserver for now) to use the power of the LLDB debugger core, yet not export it as its API is not portable or maintainable. The Host layer and many of the other internal only APIs can now be statically linked against. Now LLDB.framework/lldb.so links against "liblldb-core.a" instead of compiling the .o files only for the shared library. This fix is only for compiling with Xcode as the Makefile based build already does this. The Xcode projecdt compiler has been changed to LLVM. Anyone using Xcode 3 will need to manually change the compiler back to GCC 4.2, or update to Xcode 4. llvm-svn: 127963
