[LLVMdev] RFC: Loop versioning for LICM
Hi Ashutosh,
Have you been following the recent Loop Access Analysis work? LAA was split out from the Loop Vectorizer that have been performing the kind of loop versioning that you describe. The main reason was to be able to share this functionality with other passes.
Loop Access Analysis is an analysis pass that computes basic memory dependence and the runtime checks. The versioning decision

[LLVMdev] RFC: Loop versioning for LICM
I like to propose a new loop multi versioning optimization for LICM.
For now I kept this for LICM only, but it can be used in multiple places.
The main motivation is to allow optimizations stuck because of memory
alias dependencies. Most of the time when alias analysis is unsure about
memory access and it says may-alias. This un surety from alias analysis restrict
some of the memory based
