object allocation in JITted method

I am new to hotspot. I am wondering how object allocation is done in
JITed method ? is it done by calling out to GC runtines or every Java
thread has a thread local heap in which a simple increment of a
pointer in the thread local heap is all that is needed ( and the heap
is replenished by calling out to GC runtines if exhausted ).
