# Box: PGO Profile Configuration
# Purpose: Define representative workloads for Tiny Front
# Contract: Provides workload definitions for PGO profile collection

# Binaries to profile
PGO_BINARIES=(
    "./bench_random_mixed_hakmem"
    "./bench_tiny_hot_hakmem"
)

# Representative workloads (deterministic seeds for reproducibility)
# Design: Cover diverse allocation patterns for optimal PGO data
PGO_WORKLOADS=(
    # Random mixed: Common case (medium working set)
    # - Most representative of general allocation patterns
    # - 256 slots = moderate cache pressure
    "./bench_random_mixed_hakmem 5000000 256 42"

    # Random mixed: Smaller working set (higher cache hit)
    # - Exercises hot TLS SLL path heavily
    # - 128 slots = higher hit rate
    "./bench_random_mixed_hakmem 5000000 128 42"

    # Random mixed: Larger working set (more diverse)
    # - Exercises refill and cold paths more
    # - 512 slots = more SuperSlab allocations
    "./bench_random_mixed_hakmem 5000000 512 42"

    # Tiny hot path: 16B allocations
    # - Class 0 (smallest) intensive
    # - High allocation frequency
    "./bench_tiny_hot_hakmem 16 100 60000"

    # Tiny hot path: 64B allocations
    # - Class 3 (common size) intensive
    # - Typical small object pattern
    "./bench_tiny_hot_hakmem 64 100 60000"
