rr Deterministic Debugger

rr provides deterministic record-replay debugging with full reverse execution capabilities.

Core Workflow

1. Record: rr record <program> [args]
2. Replay: rr replay (enters gdb interface with reverse execution)

Reverse Execution Commands

All standard gdb commands work, plus reverse variants:

• reverse-next / rn: Step back over function calls
• reverse-step / rs: Step back into functions
• reverse-continue / rc: Continue backward to previous breakpoint
• reverse-stepi / rsi: Step back one instruction
• reverse-nexti / rni: Step back over one instruction
