Re: Saving all register of Boehm's Stop-World of hypermodern i686, is it reliable?

Andrew.



Why interested?
Because it's good.

I'm thinking on another thing,
as an application of GCJ-4.3 uses Vector or ArrayList, i'm thinking to
accelerate it using (from the Athlon or Pentium Optimization manual) the:

* instructions of cache's prefetching
* and XMM registers

So, updating the capacity of the Vector will be FAST!!!

The problem can be the lack of XMM's support of Boehm GC, e.g., to
support the array of pointers.

This discussion was wonderful for me ;)

Good bye
