Any suggestions for how to interpret DSCallGraph's output for the following? I'm trying to use DSCallGraph to get a conservative estimate of a whole-program SCC call graph. I wanted to see how it handles real call-graph cycles involving functions both internal and external to the module. So I made a test program with the following actual call graph, using the standard library's

Hi, When you write a program which uses the "qsort()" library function, You also have to provide an implementation of a compare funtion. Now when we convert our program into bc and then execute it, I get the number of times all basic blocks are executed. But since the comparison function is called from within the std function "qsort()", I don't get the number of times

Hi, I am trying to run an LLVM analysis on a C++ program that calls qsort(), using the LLVM interpreter (lli --force-interpreter). The code is the qsort_large.c file in the MiBench benchmark suite. If I comment the qsort() call, the execution works fine. If I uncomment the qsort() call, I run into a segmentation fault error as follows: 0 lli 0x0000000000d35c6f 1 lli

Dear All, Is there a reason why the qsort() implementation in llvm/runtime/GCCLibraries/libc/qsort.c is commented out? I've run it on Linux, and so far it seems to work fine. -- John T.

Hi, there are a couple of possible issues around array_pod_sort from STLExtras.h . Firstly, qsort() needs a comparator that returns zero on equal inputs. ConstantIntSortPredicate in SimplifyCFG.cpp (where the sort is being used to bring duplicate values together) fails this requirement. All the others look ok. Secondly, on Windows qsort() needs its callback to use __cdecl calling convention,

Hi all, UndefinedBehaviorSanitizer currently does not check for undefined behaviors which result from improper usage of standard library functions. One notorious instance of such errors is invalid usage of qsort or bsearch routines (or std::sort and friends in case of C++): * using comparison function that violates ordering axioms (reflexivity, symmetry, transitivity) * returning unstable

Solaris 5.8 has a quirky qsort that requires the ability to recognize elements as equal. here is a patch I have created to deal w/ this problem. I apologize if the patch is in the wrong format and would love to be corrected if wrong. I used the following to create the patch libvorbis-1.0> diff -u lib/psy.c lib/psy_new.c > libv.patch <p><p><p><p> --------------

I tried to install the SAFECode in LLVM 2.6 following the instruction in Install.html. But when I do the step: # cd projects/poolalloc # make I get the errore below: llvm[2]: Compiling qsort.c for Release build (bytecode) llvm[2]: Compiling strdup.c for Release build (bytecode) llvm[2]: Compiling qsort.c for Release build llvm[2]: Compiling strdup.c for Release build llvm[2]: Compiling qsort.ll

Hello, llvmdev. I'm a student from the Moscow State University and I started to work with the LLVM project. First, I have to compare its profiling ways and I got a little problem. It hangs when I try to run optimal edge profiling. Nothing happens right after the command "opt a.bc -profile-loader -o b.bc" which tries to load optimal edge profile from the llvmprof.out file. I mean it

Hello, There is a bug in the current version of vorbis/lib/floor1.c. The line that says:- qsort(sortpointer,n,sizeof(int),icomp); should be:- qsort(sortpointer,n,sizeof(int *),icomp); But somebody probably fixed that already. :) Also, I'd like to know how I can encode a file using the channel coupling modes. oggenc doesn't have an option for that yet. Greetings,

virt-p2v looks in /sys/block to find disks, and ignores the hard disk containing the root device. This is correct when virt-p2v runs off the ISO, but when running the tests on a machine that has a single hard disk, all_disks would be NULL, resulting in a test failure. Fix this by allowing all_disks to be NULL, but adding an extra check later so that we don't perform the conversion with no

Hello everyone, i`m new here.. I just started with learning R language and i have hard "homework". I need to write function like sort().. Anyone know how to do it? Can u give me algorithm for sorting vector? x=c(1,2,-1,1,3,4) or something like that..
