Pull request overview
This PR adds a --no-rebuild verification mode to the MIGraphX driver that performs a single reference run and a single target run while tracing instruction outputs by debug symbol, enabling layer-wise divergence reporting without recompiling for --reduce/--bisect workflows.
Changes:
- Adds
verify_options::no_rebuildand wires--no-rebuildinto the driver CLI. - Introduces a trace-based
verify_callbackthat captures reference outputs by debug symbol and compares them against target outputs. - Updates verify flows (
verify_program, reduced, bisected) to use the new layer-wise compare path when--no-rebuildis enabled.
