llvm dev - Feb 2015 - [LLVMdev] poolalloc and steensgaard

Hi Daniel,

To my knowledge, there is no other implementation available for Steensgaard
AA except poolalloc.
I have tried Steensgaard AA under LLVM 2.7 poolalloc, but there are lots of
bugs which need to be fixed. It will be a good idea to use previous
implementation, but you will have to modify (a lot) it with respect to the
latest version of LLVM poolalloc.

Thanks,
-Yogesh

Hi Yogesh,
Thanks for the reply.
Sounds like i have two choices:
(1) use llvm2.7 poolalloc (including steensgaard), but it is buggy?
(2) adjust steensgaard based on lastest poolalloc, but it needs too much
modification? and also the correctness can not be promised?

Daniel.

Hi Daniel,

Please have a look at the mail forwarded to you. It seems there are some
concerns about patents.

Thanks,

When questions like this one were raised in the past, there were concerns
about patents.  I think the issues were summarized in that thread, you
might try searching for it.

(As always, not a lawyer, etc...)
