[LLVMdev] another experimental patch for bug 2606
Hey all, Attached you will find an experimental patch which allows me to play with a derived JIT class. With this patch I've alleviated my concerns with forcing cross module behavior for all users of JIT. However this introduces some new semantics, and kind of circumvents the EngineBuilder API. More important though, I have not addressed any concern about using stub functions in eager

[LLVMdev] Debugging of LLVM-IR
Unfortunately, the current gdb support doesn't include line numbers. It'll tell you what function it crashed in and the stack trace though. Line numbers will probably come when the llvm-mc project is merged into the JIT. On Tue, Feb 9, 2010 at 9:37 AM, Garrison Venn <gvenn.cfe.dev at gmail.com> wrote: > Are you running this in a JIT?
