Hi,
I'm attempting to use Module::getTypeByName in my pass, but when I
run the pass with opt, I get this:
opt: symbol lookup error:
/home/mmwu/Download/32/llvm/Release/lib/ParallelSort.so: undefined
symbol: _ZNK4llvm6Module13getTypeByNameENS_9StringRefE
The pass worked before I added the call in. What do I need to link with
the pass to get it to work? Or is there something wrong with my setup?
Thanks,
Michael

Check that this library does not come before any users of the symbol on the linker command line. Ciao, Duncan.
Somehow after rebuilding LLVM, the problem went away. Thanks. I don't even think I changed my source code.
