[llvm-dev] llvm interpreter error with polybench
I am using polybench linear-algebra kernels for analysis, using these commands: $ clang-3.8 -I utilities -I linear-algebra/kernels/3mm utilities/polybench.c linear-algebra/kernels/3mm/3mm.c -S -emit-llvm $ llvm-link 3mm.ll polybench.ll -o 3mmN.ll $ llvm-dis 3mmN When I ran the file using interpreter $ lli --debug -force-interpreter -stats 3mmN.ll The interpreter stopped interpreting after the main function return without interpreting the other functions. It aborts with this error: lli: /home/rasha/llvm/llvm/include/llvm/ADT/ilist_iterator.h:139: llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::reference llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::operator*() const [with OptionsT = llvm::ilist_detail::node_options<llvm::Instruction, true, false, void>; bool IsReverse = false; bool IsConst = false; llvm::ilist_iterator<OptionsT, IsReverse, IsConst>::reference llvm::Instruction&]: Assertion `!NodePtr->isKnownSentinel()' failed. #0 0x0000000001a5e0a9 (lli+0x1a5e0a9) #1 0x0000000001a5e13a (lli+0x1a5e13a) #2 0x0000000001a5c5d2 (lli+0x1a5c5d2) #3 0x0000000001a5da40 (lli+0x1a5da40) #4 0x00007fefe0a91330 __restore_rt (/lib/x86_64-linux-gnu/libpthread.so.0+0x10330) #5 0x00007fefdfa91c37 gsignal /build/eglibc-ripdx6/eglibc-2.19/signal/../nptl/sysdeps/unix/sysv/linux/raise.c:56:0 #6 0x00007fefdfa95028 abort /build/eglibc-ripdx6/eglibc-2.19/stdlib/abort.c:91:0 #7 0x00007fefdfa8abf6 __assert_fail_base /build/eglibc-ripdx6/eglibc-2.19/assert/assert.c:92:0 #8 0x00007fefdfa8aca2 (/lib/x86_64-linux-gnu/libc.so.6+0x2fca2) #9 0x000000000106ca6a (lli+0x106ca6a) #10 0x00000000015ca46f (lli+0x15ca46f) #11 0x0000000001606fcf (lli+0x1606fcf) #12 0x00000000015cda08 (lli+0x15cda08) #13 0x0000000000f415cb (lli+0xf415cb) #14 0x00007fefdfa7cf45 __libc_start_main /build/eglibc-ripdx6/eglibc-2.19/csu/libc-start.c:321:0 #15 0x0000000000f3f269 (lli+0xf3f269) Stack dump: Is there another method to use polybench kernels with llvm interpreter? <https://stackoverflow.com/questions/tagged/llvm> -------------- next part -------------- An HTML attachment was scrubbed...
