If M < N (provably), SCEV would return an exit count for the loop which reflects this.  If not, we'd get umin(M,N).  We can still generate the vector body at the cost of inserting the umin computation above the loop body.  Both cases can be handled by running the vector loop up to the minimum trip count (well, one less to handle mid-loop exits and side effects).  The M < N case is falls out of the m...

...r plan here? I also found gcc's choice of folding builtin_object_size(0, 2) to 0 and builtin_object_size(0, 0) to -1 somewhat odd; I'd have expected the inverse. This follows from the following "intuitive" rules ObjSizeMax(X) = UMAX(ObjSizeMax(A), ObjSizeMax(B)) ObjSizeMin(X) = UMIN(ObjSizeMin(A), ObjSizeMin(B)) (where X is a value that can either be A or B at runtime) and that we want to fold ObjSizeMax(Malloc(N)) = ObjSizeMin(Malloc(N)) = N However, since Malloc can return null: ObjSizeMax(Malloc(N)) = UMAX(N, ObjSizeMax(NULL)) = N ObjSizeMin(Malloc(N)) = UMIN(N, ObjSiz...

...(and less fragile) if max and min intrinsics were recognized rather than looking for compare-select sequences. The suggestion was to change compare-selects into max and min intrinsic calls during instcombine. The intrinsics to add are: declare iN llvm.{smin,smax}.iN(iN %a, iN %b) declare iN llvm.{umin,umax}.iN(iN %a, iN %b) declare fN llvm.{fmin,fmax}.fN(fN %a, fN %b) What does the community think? Paul

...e it returns a location that has N dereferenceable bytes or NULL, it follows that ObjectSizeMin(malloc(N)) should return the smaller of ObjectSizeMin(NULL) and ObjectSizeMin(MemoryLocOfNBytes) == the smaller of ObjectSizeMin(NULL) and N. Given that we want the result of ObjectSizeMin(malloc(N)) == UMIN(ObjectSizeMin(NULL), N) to be N, we'd want ObjectSizeMin(NULL) to be (unsigned)-1 for consistency. However, none of this matters if we're not in a position to change the specification. -- Sanjoy > This is also consistent with how @llvm.objectsize already acts: if the > pointer it&...

Hi there, This is summary and patch for a bug in read.dbf, demonstrating in Message-Id: <20050818150446.697835cb.stanimura-ngs at umin.ac.jp>. After consulting Rjpwiki, a cyber-community of R user in Japan, the cause was found, and the patch of solution was proposed. Overflowing occurs when we use read.dbf for reading a dbf file having a field of longer signed integer. For example, $ dbf2txt test.dbf #KEYCODE 422010010...

...e is to add a "null is unknown size" bit to @llvm.objectsize, much like the "min" bit it already has. If this bit is true, null would be treated like an opaque pointer. Otherwise, @llvm.objectsize would act no differently than it does today. If we like this approach, I'm assuming it would be best to have this bit as a third argument to @llvm.objectsize, rather than making the second argument an i8 and using it as a bag of bits. All thoughts/comments/alternative approaches/etc. highly appreciated. :) Thanks (and Happy Holidays)! George -------------- next part -----------...

I've recently mentioned in a few places that I'm interested in enhancing the loop vectorizer to handle multiple exit loops, and have been asked to share plans.  This email is intended to a) share my current thinking and b) help spark discussion among interested parties.  I do need to warn that my near term plans for this have been delayed; I got pulled into an internal project
