[llvm-dev] debugging Orc JIT'ed code

[Stefan Gränitz via llvm-dev]

Hi Geoff, hi Alex

If you implement the GDB JIT Interface in your Orc JIT, this is in
general possible (at least from the JIT's point of view) with both
debuggers, GDB and LLDB. Please have a look at the example here:
https://github.com/weliveindetail/JitFromScratch/tree/jit-debug/gdb-interface

You will probably need to adjust the code depending on the LLVM version
you are using. As described in the readme, however, getting it to work
in practice depends on a few more details. To Keep it short:
* Linux: works out of the box
* macOS: possible, but cumbersome (the example is not up-to-date here)
* Windows: I lost hope (haven't looked at it for a long time though)

Best
Stefan

I had to move to the Orc API in order to be able to call modules' constructors and destructors as needed, but I would quite like to be able to debug and profile the resulting code as well...
