9// NOTE: This is a native-only debug/perf logging hook.
10// The original C++ iterates over module protos and native protos, logging each function.
11// We preserve the null-check behavior on gPerfLogFn by checking the global flag.
12// The global gPerfLogFn and gPerfLogContext are defined elsewhere and accessed via FFlag-like globals.
13// Since the source uses a function pointer global, we model it as a static Option<fn> in luau-common.
14// However, the current luau-common does not expose gPerfLogFn as a Rust global.
15// To avoid a missing dependency, we keep this stub and assert if called.
16// The actual logging is conditional on gPerfLogFn being non-null; we cannot implement that here.
17//
18// This function is called from StandaloneCodeGenContext::bindModule and SharedCodeGenContext::bindModule.
19// It is native-only and not used in wasm builds.
