[llvm-dev] Optimised-code debugging experience Round Table

[Cazalet-Hyams, Orlando via llvm-dev]

Hi all,

I haven't seen a proposal for an optimised-code debugging experience Round Table yet so here goes!
Please let me know if you are interested by emailing me at:

    orlando.hyams at sony.com

Below is a non-exhaustive list of possible topics. Feel free to include any preferences and
suggestions in your response.

  a. Line tables:
    1. Can we fix is_stmt?
    2. Is prologue_end reliable?
    3. General stepping behaviour/quality.

  b. Variable locations:
    1. The state of DW_OP_entry_values in llvm.
    2. The state of the instruction-referencing DBG_VALUE work.
    3. The state of multi-register DWARF expressions in llvm.
    4. The possibility of salvaging out-of-liveness values using the 3 projects mentioned above.
    5. Floating point debug-info quality in llvm.
    6. Loop induction variable locations.

  c. Testing debug-info:
    1. Variable correctness testing tools.
    2. Location coverage testing tools.

  d. The state of -Og.

Please respond before Friday (25th) if you are interested as that is the submission deadline.

Thanks,
Orlando
