The question is: does a disassembly of it have value? One use case put

Overall it looks really nice – I’ve only found one obvious bug that I’m packaging up a patch for now. Glad you're liking it! I haven't really done comprehensive testing yet—it passes all the decoding tests

Hello. I tried to get the trip count of a loop with Scalar evolution. I got inspired from http://stackoverflow.com/questions/13834364/how-to-get-loop-bounds-in-llvm . However the analysis described there doesn't work well for the second inner loop of thes function below (although if we declare Bcols a short it works well): void MatMul(int Arows, int Acols, int Brows, int

Hello, I am trying to use scalar evolution pass using following command; opt -analyze -mem2reg -indvars -loop-simplify -scalar-evolution < vec.bc when vec.bc is generated using newer version of LLVM i.e LLVM 6 and 7 i get following message in the end; Determining loop execution counts for: @main Loop %8: Unpredictable backedge-taken count. Loop %8: Unpredictable max backedge-taken count. Loop

Hi, I'm looking at the new ARM disassembler, and performing testing to see if there are any obvious bugs I can fix. Overall it looks really nice - I've only found one obvious bug that I'm packaging up a patch for now. Currently it does not provide information as to whether a particular bitpattern was UNPREDICTABLE or not. For example, an invalid bitpattern may return correct

Hi Junbum, > I was aware that the definitions of target RegisterClass (outs) are different in t2LDRSB and t2LDRSB_PRE. While t2LDRSB uses rGPR, t2LDRSB_PRE uses GPR. I wonder if lr and pc are already prevented from being allocated in pre-indexing case, because of some register hint that is being enforced? They're not allocated during CodeGen because of the Reserved.set(…) calls in

On some machines running PowerPath, there''s sometimes issues after an update/upgrade of the PowerPath software. Sometimes the pseudo devices get remapped and change names. ZFS appears to handle it OK, however sometimes it then references half native device names and half the emcpower pseudo device names. So the SA can easily be confused. Is there a way to tell ZFS which device names

I've been looking through the archives and have not been able to find anyone with a similar problem but perhaps I'm not searching in the right places. The problem is that my outbound call sometimes go though and sometimes don't. If someone can point me in the right direction it will be highly appreciated.

I filed this as a bug, but wanted to post this to the ng to check if anyone has ever seen this. I'm using samba 3.0.4. This is a somewhat weird situation, so please bear with me through the description. The following path: "C:\! 01 Carte Geografiche\carte\" When read with smbclient the windows share will only show 160 files in the folder. When read on the windows machine it

Hi, I have a very bizarre problem linking to my Active Directory from my Ubuntu 11.10 system. I have three AD users setup with them belonging to a specific AD group. When I first login a user onto my Ubuntu system, that user is shown to be a member of the group: wbinfo -r <user> And if I show the group members, it also lists my user: wbinfo --gid-info <gid> However - after a

Hi friends, I''m facing a very strange problem... I consume a webservice from within my rails app. I''ve written a thin wrapper around the webservice using Net::HTTP.post_form However, when calling the API from within my controllers, the API calls randomly fail, complaining about timeout. But - when I wrote a simple iterative test (500 iterations), calling the same webservice

Hello everyone At EuroLLVM I presented some testing work we have been doing on improving correctness of the MC Layer for ARM. There seemed to be interest from the community in seeing the results of this test suite. Background ----------- We are using a test suite, called MC Hammer, that compares MC with an ARM in-house implementation of the same functionality. The test space for this suite is

Hello, I have recently started having problems with my installation of Samba that I can't attribute to any single cause. On some of the computers I have networked (like 2-3 of total 40) sometimes I can't access some shares (again, 2-3 shares from 26 total). When this error occurs, Windows client tells me I might not have proper privileges but I can access the same share with the same
