Good hint. It is controled by HAVE_TLS -
371 inline ThreadCache* ThreadCache::GetThreadHeap() {
372 #ifdef HAVE_TLS
373 // __thread is faster, but only when the kernel supports it
374 if (KernelSupportsTLS())
375 return threadlocal_heap_;
376 #endif
377 return reinterpret_cast<ThreadCache *>(
378 perftools_pthread_getspecific(heap_key_));
379 }
HAVE_TLS is defined if compiler supports __thread.
I disable the option manually. It looks better now and help me to find some
missing patches.
Is it safe to close it?
