The question is: does a disassembly of it have value? One use case put to me was in a debugger, where one needs to know if an instruction was ARM-mode or Thumb-mode so it can correctly guess the mode of the previous instruction in the stream and disassemble that correctly. OK, I think I was misun...

For example, an invalid bitpattern may return correct disassembly for an alternative, predictable instruction meaning that the sequence X -> disassemble -> assemble -> Y could end up with X being different to Y.

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

Overall it looks really nice - I've only found one obvious bug that I'm packaging up a patch for now.

...e Reserved.set(…) calls in ARMBaseRegisterInfo.cpp. That said, this inconsistency is probably wrong anyway (or at best an approximation to reality) because it affects what the assembler supports. For example ldrsb sp, [r0]! is allowed, but ldrsb sp, [r0] is forbidden. I think they should both be UNPREDICTABLE (though this is an understandable error; support for unpredictable is in its early stages). Annoyingly, there is *some* distinction between the writeback and non-writeback versions. Fixing it properly might get hairy rather quickly. Tim.

...lf the emcpower pseudo device names. So the SA can easily be confused. Is there a way to tell ZFS which device names to use? Is there a way to change which devices are referenced in a current pool? I know about the "-d" option to zpool, however to use the names in /dev/dsk can lead to unpredictable results (due to unpredictable SA''s).

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.

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, 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
