Xiao-Feng, Even if you do not need to have constant offsets, it's better to use TM directly to allocate TLS slots. In this case we can remove extra code from VM: the computation of the third parameter in the next method:
extern Managed_Object_Handle (*gc_alloc_fast)(unsigned size, Allocation_Handle type, void *thread_pointer); On 10/25/06, Mikhail Fursov <[EMAIL PROTECTED]> wrote:

But in this case you can't tell that you have constant offset from fs[14] to your data for all threads. So you can't inline your helper in JIT. -- Mikhail Fursov
