[webkit-dev] [Block Pointer] Deterministic Region Based Memory Manager

[Ryosuke Niwa]

Hi Phil,

You made a similar post in December 2014:
https://lists.webkit.org/pipermail/webkit-dev/2014-December/027113.html

Are you suggesting you have done or ready to do the following?

> Let’s be clear, though: we’re unlikely to accept a patch in which all of our JS object references are replaced by uses of your block_ptr, unless that patch is a significant speed-up on web benchmarks, there aren’t any slow-downs, and you can prove that all of the JSC GC’s lifetime semantics are preserved (including tricky things like the relationship between Executable objects, Structure objects, and CodeBlocks).

Otherwise, I don't think we would be adopting your memory management
library anytime soon.   I don't think we're interested in
experimenting with your library on behalf of you either given
implementing a concurrent GC on top of our existing GC would be much
lower risk and will address some of the issues you have pointed out in
the thread.
