An example testcase for use in the debugger. Currently you can do stuff like stepping, next'ing, finish'ing, stacktraces, source listings, etc. You can't print program variables yet though. Oh, and I lost my nice commented version of funccall.ll :( Test with: llvm-as funccall.ll llvm-db funccall.bc <arguments> This is not automatically testable yet, and the C front-end doesn't support debug information yet. That said, it's a start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10689 91177308-0d34-0410-b5e6-96231b3b80d8 Chris Lattner 16 years ago
