Hello Sir, Im trying to test run pbqp register allocator for small C programs. by llc -regalloc=pbqp -debug <bitcode of the file> It is giving me segmentation fault for even very simple programs having loops or if statements. Please tell me where I'm going wrong. -- Regards, Smriti Jaiswal MTech Dept of Computer Science and Engg, IIT Kanpur -------------- next part -------------- An HTML attachment was scrubbed...

(along with the exact command line) if you can repro this crash with C source and Clang, the Clang crash reporting mechanisms (it will provide a .sh and .i file & instruct you to attach those files to a bug report) are quite handy when reporting bugs. -------------- next part -------------- An HTML attachment was scrubbed...

The simple C code on which im running the allocator is attached. And these are the set of commands. I dont understand ..guess i might be doing something very silly. Please help *Commands:* clang -emit-llvm -c test.c -o test.bc opt -mem2reg test.bc -o testssa.bc llc -regalloc=pbqp testssa.bc On Mon, Aug 12, 2013 at 7:59 AM, David Blaikie <dblaikie at gmail.com> wrote:> > > > On Sun, Aug 11, 2013 at 12:36 AM, Smriti Jaiswal <jaiswal.smriti at gmail.com > > wrote: > >> Hello Sir, >> >> Im trying to test run pbqp register allocator for small C programs. >> >> by >> >> llc -regalloc=pbqp -debug <bitcode of the file> >> >> It is giving me segmentation fault for even very simple programs having >> loops or if statements. >> Please tell me where I'm going wrong. >> > > Could you provide a specific example file (preferably a particularly > simple one) that reproduces this problem?
