[Mesa-dev] [PATCH 0/2] Hash table cloning for copy propagation

[Thomas Helland]

I've also uploaded this series to my github, if you wan to
pull them down from there [1].

I've also uploaded my previously talked about pointer_map
to my github account [2]. There's a pointer map, pointer set,
and some patches for nir in there, and some for disabling
asserts in some places. So it's not ready for primetime,
but that series has been tested recently, and has been
stable for a couple months now. Been tinkering with it
and adding small pieces now and then. What remains is
a bench-a-tonne to ensure it is OK performance wise,
and cleaning it up for posting on the mailing list.
