tracy/examples/RocprofOnDemandRepro/check_gpu_ctx_name.cpp

// Loads a .tracy file and prints the GPU context names.
// Used to verify that on-demand profiling correctly defers the
// GpuContextName message so late-connecting clients see the name.
//
// Usage: ./check_gpu_ctx_name trace.tracy
// Expected output: "GPU context 0: rocprofv3"
// If name is missing: "GPU context 0: (unnamed)"
