Well, AFAIU this part of Mikhail's proposal is not mandatory for all GCs. You can use original interface functions for GCv5: malloc GC TLS structure and install only one pointer into TLS.
The only thing we need to change is to make GC to access and allocate its data by itself (for greater modularity). -- Ivan On 10/25/06, Xiao-Feng Li <[EMAIL PROTECTED]> wrote:
Yes, this can be an optimization. I am not very sure if we can get obvious performance improvement with this. I am usually conservative with interface change. :-) Since neither Windows nor Linux provides this kind of native support, I am guessing they have their rationality. We probably want to delay this optimization in TM until we have evidance for it, since what Mikhail wants is just to inline GC tls data access easily.
