+Subject: [PATCH 1/3] Fix the --enable-shared build.
 
-    Fix the --enable-shared build.
+Currently a build configured with ./configure --enable-shared breaks
+with an undefined "llvm::cl::parser<llvm::PassInfo
+const*>::getOption(unsigned int) const" symbol when linking opt.  This
+body for this symbol gets emitted into Pass.o (along with the destructor
+for PassNameParser), but gets linked into libLLVM-3.5svn.so with local
+visibility, causing the link error.
