Summary: I think this is better solution than annotating callsites in IC/SLC.

[SimplifyLibCalls] Add dereferenceable bytes from known callsites
Summary:
int mm(char *a, char *b) {
return memcmp(a,b,16);
}
Currently:
define dso_local i32 @mm(i8* nocapture readonly %a, i8* nocapture readonly %b) local_unnamed_addr #1 {
entry:
%call = tail call i32 @memcmp(i8* %a, i8* %b, i64 16)
ret i32 %call
}
After patch:
define dso_local i32 @mm(i8* nocapture readonly %a, i8* nocapture readonly %b) local_unnamed_addr #1 {
entry:
%call = tail call i32 @memcmp(i8* dereferenceable(16) %a, i8* dereferenceable(16) %b, i64 16)
ret i32 %call
}
