[LLVMdev] How to change default AA with opt? (Change default impl for an analysis group with opt?)
Hi all,
I'm working on an AliasAnalysis pass that is loaded as a module.
What I'd like to do is something like:
opt -my-aa -O3
Where -O3 is whatever set of optimizations I'm using, but they all
should use 'my-aa' for their results.
However, what appears to happen is it uses my-aa until something
invalidates those results and then goes back to basic-aa when
something needs

No.

Probably. I added some text to docs/AliasAnalysis.html in r106776
for the issues that I ran into when developing a new AA implementation.
