// Test that script sources are properly registered on consecutive profiler runs.
// Bug 2002982: When the profiler is disabled and re-enabled, script sources
// need to be re-registered because the profiler's ScriptSources hashset is
// cleared on stop. Previously, ensureProfileString would return early if
// profileString_ was already set. And that was causing us to never re-insert
// the script source.

// Set a low warmup threshold to trigger baseline compilation.
setJitCompilerOption("baseline.warmup.trigger", 5);

// A simple function that will be JIT'ed.

  return x * x;

// Warm up with the profiler enabled. It creates JitScripts and registers
// their sources.
