Hi all, While developing compile-time instrumentation for ThreadSanitizer (http://code.google.com/p/data-race-test) I need to generate SEME regions without loop and call instructions (I'll call them superblocks hereafter, although some researchers do allow loops in their definition of superblocks). This is necessary to get the largest piece of IR in which the memory operations can be enumerated in order to record the addresses of...

...inistic of course. 2) An intermediate step to whole function isel is to do region based isel with regions limited by what makes the sched problem simple. One very interesting class of region is a Single-Entry-Multiple-Exit region. It would be straight-forward to break each function into SEME regions and select them one at a time, allowing them to compile to multiple MBBs. In addition to the obvious dag combiner and isel improvements that would come from larger regions, SEME regions encapsulate a number of interesting things (such as switch lowering). Having SEME regions wou...

I know that this has been discussed (at least in passing) a few times on the list, but I couldn't locate a bug for it. Have any architectural plans been made for it? Are there architectural roadblocks with the current LLVM infrastructure that will complicate the process? What has demotivated the implementation of this so far (is it not that big a benefit on important targets, too

Very nice! Why did you decide on hyperblock instead of SEME region and how are you forming the blocks?

...s on Makefile for the Makedeps and R targets. I am using gnu Make 3.79, gcc 2.95.3, Solaris SunOS5.8 on an UltraSparc. I double checked that I had found the problem by rerunning make with the distributed makefile restored, but the looping behavior did not recur. When I ran make check, everything semed to be OK.

I thought I'd share a little bit of progress I made this weekend. I've gotten the first interesting test-case (a simple switch) through hyperblock-based DAGISel, and there's a pretty picture too! Each part of the switch is emitted directly into the DAG, rather than being deferred. This is the function: define i32 @foo(i32 %x, i32 %z) nounwind { entry: switch i32 %x,

...sion of ThreadSanitizer instrumentation) Tobias Grosser has suggested to use RegionInfo: did you have a look at the RegionInfo pass? It currently detects some kind of refinded SESE regions. I use them in Polly and as far as I know the Intel OpenCL SDK also uses them in some way. It is not SEME, but it may either fit your needs or we may think about extending it. If you want to give it a try you can use: opt -view-regions-only file.ll It would be great if we could have just a single RegionInfo analysis that can then be used by other passes to detect and/or generate the k...

G'day all, I update wine daily from cvs and install it into /usr/local/wine using a custom script, not the wine install script. Previously all the shared libs were in /usr/local/wine/lib and this dir was picked up by ldconfig and everyone was happy. Now I have /usr/local/wine/lib and /usr/local/wine/lib/wine ldconfig picks up the former but not the latter. To get wine to work I have to set

Hi, I'm trying to solve a problem from StructurizeCFG not actually handling regions with multiple exits. Sample IR attached. StructurizeCFG doesn't touch this function, exiting early on the isTopLevelRegion check. SIAnnotateControlFlow then gets confused and ends up inserting an if into one of the blocks, and the matching end.cf into one of the return/unreachable blocks. The input to

...jump to B somewhere above A? If we use dominates, and i put a jump there, i can make A and B dominator tree siblings. Is the pointer now invalid? :) etc I suspect what is really wanted is "i want lifetime markers to specify that this thing has single-iteration scope, function scope, or SESE/SEME region scope" (or something).

Hello I wonder whether there is an r tool or package available for testing for the null of same skewness or kurtosis of two independent samples. It semes that nsRFA package uses L-moments for soothing similar but I could not get how to use the package for the above test. Any pointers, help, example and etc. will be most welcome.

G'day all, I am struggling with a problem I can't identify, related to window focus when running wine not using desktop or managed mode. When using managed mode, it works wine, but I want to use it in this instance with an xinit /usr/bin/wine programname This works ok, until I get some sort of message dialog come up, then what happens is wine seems to switch focus rapidly between the

Hi folks, today I tried to switch from a samba 2.2.2 PDC to a samba 2.2.7 PDC. Everything semed to be working fine with smbclient. Windows user couldn't log on, but with following differences: * users belonging to the domain admin group could log on from Win2k boxes * normal users couldn't log on from win2k boxes, with the usual "check if you didn't mis-type userna...

Hi! I'm having problems with SeaClear II v1.0.0.196. After setting up the symlinks in ~/.wine/dosdevices pointing to my gps-device (GlobalSat BU-353 USB) everything works as expected, but for some reason Wine/SeaClear steals all available CPU-time. 100% all the time. This problem does not exist if I start SeaClear with the GPS disconnected, making me belive there is a problem with

Hi guys, I do seme help-out work for a company whose IT guys setup a FC4 box with Samba (fully up to date via YUM) running as a DC. The client desktops are all identical (at least after they got stolen and replaced). Profiles are roaming, so the users can log on on any machine. The software they run is fairly limit...

...nix_convert begin: name = %u, dirpath = , start = %u I traced this to the "logon path" configuration item. Samba is choosing the value from the smb.conf file because I don't have these values set within the LDAP directory; I just want to use the default generated one. However, it semes that Samba is NOT substituting the "%u" in this case even though it was when LDAP was not in use. At least "logon path" and "logon home" are affected; maybe more. To verify, I manually changed every "%u" in the smb.conf file to "bcwhite" and t...
