[LLVMdev] ValueTracking's GetUnderlyingObject vs. ScheduleDAGInstrs' getUnderlyingObject
Hello all. I'm investigating a problem with "Machine Instruction Scheduling" that is rooted in incorrect alias information. Things go wrong in the "Merge disjoint stack slots"[1] pass when a store instruction fails to get updated after its stack slot is merged. As a result, when "Machine Instruction Scheduling" runs, it incorrectly re-orders the store and a subsequent load, thinking that they do not refer to the same underlying object whe...

[LLVMdev] [PBQP] Are edges between nodes from totally disjoint register classes necessary ?
Hi Lang, While working on improving the debug dumps of the PBQP graphs, I found out that we can have some edges between nodes which belong to totally disjoint register classes (for example, on AArch64, this would be an int and a floating point register). Although it is true those 2 registers interferes, in the sense they are alive at the same time, they never have any physical interference, and this shows up as a zero matrix. I was wondering if it co...

Finding non disjoint regular expressions
Hello, Is there any way I can use the gregexpr functions (or a different function) in a manner that will also return overlapping (i.e. non disjoint) regular expressions? For instance, when running gregexpr("AAA","AAAAAA"), I get two matches, one at position 1 and one at position 4. I'd like to receive 4 matches at positions 1, 2, 3 and 4. Thanks, Schraga Schwartz Department of Human Molecular Genetics and...

plot(type="l") disjoint between 100 and 101st datapoint
...plotting in line mode (type="l"). plot(1:102, type="l") reproduces the problem consistently on my machine, on both png and quartz devices.

Is this purely a mac issue? Unfortunately I don't have any other machines to test it on. Kind regards, Richard...

[LLVMdev] alias set collapse and LICM
So, you can't have disjoint sets, and have one of set that says "i access everything". Because it would contain everything :) Thus, I assume by your description you meant "we want to maintain multiple disjoint partitions of the same set of accesses" (which is not quite the same as just having one special...

Samba-LDAP PDC - Disjoint uids required for different ou's?
Specifically what I am asking is, if I have a computer named ralph$ who is uidNumber 678 in ou=Computers and I have a user who is uidNumber 678 in ou=People, will this cause problems? Must the different sets of uidNumbers be disjoint acrossed different ou's?

[LLVMdev] Casting between address spaces and address space semantics
...ation. Just like TargetData, this can be added to the passmanager by the tool running the passes. Unlike TargetData, however, I wanted to be able to subclass TargetAddrspaces to change the behaviour. To make this possible, I made TargetAddrspaces an analysis group, with a default implementation AllDisjointAddrspaces (which, as the name suggests, returns Disjoint for all combinations). Having a default implementations is useful, so tools are not required to add a TargetAddrspaces pass to a passmanager. The last part of this patch is an addition to InstCombine to make use of this information: It remov...

disjointed namespaces with samba working?
Hi, is it possible to use a so called disjointed namespaces without having to "fake" the hosts fqdn giving it the AD-name as hostname? Background: We have a unix and a Windows world and each runs below it's domain. Let's say UNIX-DOMAIN and WIN-DOMAIN. When there is the need to bring the two worlds together the first choice i...

[LLVMdev] Casting between address spaces and address space semantics
...ly using the TargetData string that gets embedded in the module. So, I guess embedding this info in TargetData makes more sense. How would this look like? I would think of something like: as1:<2:=3:>4:!3 This would mean address space 1 is a subset of 2, equivalent to 3, a superset of 4 and disjoint with 3. A number of these could be present in a TargetData string, to fully describe the situation. Any relations not described mean disjoint. Relations can also be implicitely defined, ie, as1:<2-as2:<3 also implies as1:<3. I'm not sure if the > should be present, since that'...

Opinion on R plots: connecting X and Y
...rnorm(100) plot(x, y, bty='n') A colleague (and dreaded SAS user) commented that she thought that my plots could be "cleaned up" by connecting the X and Y axes. I know that I can do that with bty='l' but I don't want to, I find that the plots look less cluttered with disjoint axes. However, I was intrigued enough by her comments that I decided to solicit the opinions of others on this issue. Are there principled reasons why one should prefer joined axes or disjoint axes?

similar instructions with disjoint register files
I'm working on a backend for a target with multiple functional units, each with a dedicated register file. Several instructions can operate on any one of the functional units. For example there is an add instruction on the A unit that adds two A registers, and another on the D unit that adds two D registers, but neither can use the other's registers. From a selection point of view either

[LLVMdev] Tagged (Disjoint) Unions
I have been looking through the LLVM documentation, and I have decided that I would be interested in producing a functional front-end for it, if only to determine how applicable the optimizations that it already performs are to such a language. However, I have run into one obstacle that would make it difficult to write many of the things I would like to do. Is there a way to represent a

[LLVMdev] alias set collapse and LICM
> Can you explain why the alias sets are collapsed into one here? If I'm reading the code correctly, it is because the readonly call aliases all of %a, %b and %c. Since two pointers can be in two different alias sets only if they do not alias, %a has to be in the same alias set as the read only call and so does %b and %c. Therefore, all of them have to be in the same alias set. > Can
