Currently
DedupGroup
is added to almost every module includingEICG_wrapper
. However EICG_wrapper later becomes intrinsic when a compiler optionfixup-eicg-wrapper
is given. This causes a compilation error since annotation is added to an intrinsic. The right fix is to use to EICG intrinsic in the first place but there are still a few things to migrate ( ExtractInstances). Since dropping DedupGroup annotation on EICG_wrapper is practically safe this PR removes the annotation with a warning.
