[llvm-dev] [IPRA] Do we required more aggressive shrink-wrapping optimization?

Hello Quentin,

I see your work on shrink-wrapping optimization at
http://reviews.llvm.org/rL236507
IPRA has benefited shrink-wrapping optimization ( I have noticed that on
sqlite3 test-case) so I did read Fred Chow's paper and compare that
approach with yours I did not understand much of your work :-( in
comparison to  original paper but I feel that current approach is not
generating same results as data flow analysis based approach. Also I do not
understand one of your comment on review :

IPRA should we go for more aggressive version or the current version is as
capable as original paper ?

Sincerely,
Vivek
