It seems the same bug is there if we do pointer swapping with selects. Do you agree? (see example below) define void @f() { entry: %a1 = alloca float, align 4 %a2 = alloca float, align 4 br label %loop end: ret void loop: %phi = phi i32 [ 0, %entry ], [ 1, %loop ] %select_cond = icmp eq i32 %phi, 0 %ptr1 = select i1 %select_cond, float* %a1, float* %a2 %ptr2 = select i1

Alias analysis is figuring out the relationship between two pointer expressions, at some location in the program. At a given point in the program, do two expressions always refer to the same location? At a given point in the program, do two expressions never refer to the same location? AliasAnalysis::alias() doesn't explicitly take a "point" in the program because we don't

Oh. So it wasn't just the memory location size that was incorrect on those aliasing checks. I took a look at the tests and it appears that the alias call also catches some cases of restrict/noalias attributes, along with the tbaa info. My first idea of constructing an alias call with no Ptr's but valid tbaa info won't catch that at least. I will create a bug report and try and see if

Hi, Does this kind of IR have "undefined behavior" under LLVM semantics or is it acceptable? (TLDR: a store of i64 at offset n, followed by a load of i32 at offset n+1.) define void @foo(i32* %A, i64 %n) { entry: %arrayidx = getelementptr inbounds i32, i32* %A, i64 %n %arrayidx_cast = bitcast i32* %arrayidx to i64* store i64 0, i64* %arrayidx_cast, align 4 %add1 = add i64 %n,

Hi Johannes, I followed your advice and got the same result: NoAlias and No dependence. Would you say AA is faulty for saying NoAlias or DA is faulty for saying no dependence? Or both? (revised example below) Thanks! define float @f() { entry: %g = alloca float, align 4 %h = alloca float, align 4 br label %for.body for.cond.cleanup: ; preds = %for.body

Hello, (fairly new around here, apologies if the question has an obvious answer) I've been studying the structure of the new PassManager in the hopes of using it soon. After watching a couple of talks (Chandler / Sergeev), I decided to start with the Concept/Model classes in PassManagerInternal.h While I could make sense of almost everything there, two details caught my attention: 1- The

Hello llvm-dev, I would appreciate your feedback on the following problem. We're trying to determine whether this is a bug in LLVM or not. In the IR snippet below, we have two pointers (p and q) which initially point to two completely non-overlapping locations. Then, on every iteration of a loop, we swap the pointers and load from the first, followed by a store to the second. 1) AA says the

Dear R-users, I would like to know what are the commands to install (from a local zip file) a package and then to load it.

Hi all, I am using the function "plotCI" with the following command: plotCI(m.residuos.p.2 [1:41],li=m.residuos.p.3 [1:41],ui=m.residuos.p.4 [1:41],lty=1,ylab="") This generates exactly what I want except for the fact that I wanna drawn a line linking the points (m.residuos). How could I do that? Thanks a lot in advance, Caio [[alternative HTML version deleted]]

Hello, Does anyone knows if there is any plugin for Sweave to run on WinEdt, or any other windows Latex editor? Many thanks, JP

Hi, everybody I've just got this problem. On my network I have one SQL Server DATABASE running in my NT Server. This is not a PDC, just a SQL Server. I'm trying to set up a Domain Control using SAMBA server which is runnig in my Linux RH 7.3 BOX. So the problem is: I need to use name resolution, like WINS. Because my windowdos 98 clients find the DATABASE server by name, as well as

Hi all, Does anybody know if it is possible to build a fractional factorial design in R? That is, suppose that we want do design an experiment with 3 factors with 2, 3 and 3 levels, respectivly. However we want to consider, let's say, only 6 from all possible level combinations. Does R design such experiment? Thanks in advance, Caio [[alternative HTML version deleted]]
