[LLVMdev] Questions bout the Steensguard AA Pass in rDSA

[Daniel Guo]

Hi Criswell,
Thanks for the reply.
I am looking for a pass for the intra-procedural alias analyzing, as i am
working on multithreaded debugging and looking for a way to pick up
instructions from different threads accessing the same global variable, and
is Steensguard workable for this scenario? or any other suggestions?

I also find that the "rDSA" folder is not included in the Makefile, and
this means the -dsa-aa pass is still not reliable and probably i cannot use
it, right?

Thanks,

Dan.
