getModuleResourceUsageJSON() [1/2]

static llvm::json::Object getModuleResourceUsageJSON ( const ResourceUsageAnalysis::ModuleResourceUsage &  usage )

static

Convert ModuleResourceUsage to JSON object with full hierarchy.

This creates fully-elaborated information including all child instances.

getResourceCount()

static std::optional< std::pair< std::string, uint64_t > > getResourceCount ( Operation *  op )

static

Get resource count for an operation if it's a tracked resource type.

Returns (operation name, count) pair, or std::nullopt if not tracked. The operation name may include additional information (e.g., LUT input count).
