Just my $0.02: Actually VM_thread contains thread-local data. The VM_thread is a thread local data by itself. HyThread keeps a pointer to it, so VM_thread is always accessed from HyThread. Some of the components, e.g. GCv4 and GCv5, keeps all thread local data in VM_thread, but others JIT, GC_CC use more up to date method and request TLS slots directly from TM.
Today we are in a transition from the old model when all TLS data was stored in VM_thread to the new model - when every component requests TLS slots independently from TM On 10/30/06, Nikolay Kuznetsov <[EMAIL PROTECTED]> wrote:
Yes, this data is non threading and separate fields of VM_thread structure should be replaced with independent values (data structures) stored in TLS under separate keys. Nik.
