...hopefully someone else was able to help out with this? If not let me know and I'll look into re-activating it. I certainly think I would have remembered de-activating you myself if you had done something wrong, so I have no idea what happened here.

Hi, Could anyone tell me how exactly do I use "Type Based Alias Analysis"? I compiled the C program with Clang, and verified that there is tbaa metadata in the IR code. But then when I use "opt -tbaa input.c.bc -aa-eval" to check the results, it always gives 100% may aliasing no matter what input. Am I using "tbaa" correctly? Thanks. Yi

Hi John, Thank you for your reply! Please see my other questions below: > DSA is a unification-based points-to analysis.  The interface to use it as > an AliasAnalysis pass was removed since no one was using it and it was > probably buggy. - When you say "it was probably buggy", what is buggy? the "interface", or the AliasAnalysis? I'm so surprise that no one

Hi !            I am new to R. Can somebody help me in reformatting huge output files ,i.e, rearranging sets of columns in specific order. For example: I have data for three compunds 1, 2 and 3 file1: ID CA1 CA3 CA2 MA2 MA1 MA3 1 14 15 13 7 12 3 2 19 7 12 10 14 5 3 21 12 19 6 8 9   to File 2:   ID CA1 CA2 CA3 MA1 MA2 MA3 1 14 13 15 12 7 3 2 19 12 7 14 10 5 3 21 19 12 8 6 9   or File3: ID

Hello, I am author of a Morse code training software written in Perl at http://starling.ws/morse Currently I output to *.wav and, if on Unix, convert to *.ogg. And that's okay for a trainer. But I have desire to upgrade the project to a real-time communication tool...or at least a Morse code audio mail routine. And I should like to avoid *.wav. I'd like some means of writing a pure

Hi all. New to this list so ... sorry if this is old, but I have searched honest. I have been asked to install samba on some (60) macintoshes. The macs run OSX10.2. I have the developer tools and samba 3.0.0. Configure works but make crashes out with libsmb/clikrb5.c139: #error UNKNOWN_GET_ENCTYPES_FUNCTIONS followed by 4 more errors ((caused by the first?). I cant see any ref to this or options

Dan, Could you disclose more details about how to implement the "incremental steps" to handle more complicated alias cases? For example, differentiate different pointers that

Hi, I met an alias analysis problem in the LICM phase. I am using the following piece of code to present this problem. 1 int size; 2 int ** AAA; 3 void * xalloc(int); 4 5 void foo(void) 6 { 7 int i; 8 AAA = (int**) xalloc(size * sizeof(int*)); 9 10 for (i=0; i<size; i++) 11 AAA[i] = 0; 12 } This code tries to

Dan, Thanks for clarifying. This makes perfect sense. Gan >> Makes sense.

I'm running samba 2.2.8a on a redhat 9 box, everything works great, but ever since I playd with the system-auth I now have to enter a password in twice when I logon to the console.

Hello, I have a dataset with 4 variables, each consisting of a vector, all with the same length. I start by interpolating the first three variables using the function "interp", and plot the interpolation successfully using "filled.contour". I then interpolate the first two variables and a fourth using "interp" again, but when I try to overlay the contour lines

Nick, The problem is that LLVM's implementation of TBAA does not distinguish between these two types: i32*** @AAA and i32** %arrayidx. We believe that type based alias analysis should, in general, be able
