# HRR (HIP Record & Replay) tests

# Source files compiled into HrrTest:
#
#   hrr_format_test.cc   — CPU-only: archive format I/O unit tests (no GPU).
#   hrr_recovery_test.cc — CPU-only: crash-truncation recovery unit tests for
#                          the archive reader (no GPU).
#   hrr_workload_test.cc — Hidden ([.][hrr-direct]) GPU test cases invoked as
#                          subprocesses by hrr_roundtrip_test.cc; provides clean
#                          Windows process context for HIP + capture layer.
#   hrr_repro_workload_test.cc — Hidden ([.][hrr-direct]) regression micro-kernels
#                          (first-hipMalloc capture, embedded-pointer struct
#                          args, uncaptured-host-write divergence, null optional
#                          output pointer 0x20000 fault class, replay zero-init).
#   hrr_roundtrip_test.cc — Round-trip: sets HIP_HRR_CAPTURE_OUTPUT, spawns
#                          Unit_HRR_GpuWorkload_Direct / Unit_HRR_GraphWorkload_Direct
#                          as subprocesses, then runs hrr-playback to validate
#                          replayed D2H buffers byte-for-byte against captured blobs.
