call graph

Hello. I'm wondering if LLVM can generate a call graph across
multiple files? Does 'analyze' accept multiple bytecode files? Can I
concatenate multiple bytecode files into a single file for input?
Thanks.

You want to concatenate the bytecode files using llvm-link and then run analyze on the new bytecode file to generate the call graph.

You should check out the man pages for analyze and other llvm tools on the documentation webpage. You can also run the tool with "--help".
