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.
|
|
|
|
This fix uses the existing EXTERN_TEMPLATE machinery to force a globally
|
|
visible definition for the functions in parser<const PassInfo *> into
|
|
Pass.o.
