[LLVMdev] VMkit AOT build problem: llc crushed on glibj compilation to native(.s) file
Hi, Trying to build AOT version of vmkit java, building for that classpath glibj.zip: $ cd vmkit/tools/vmjc/libvmjc $ make ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1 REQUIRES_FRAME_POINTER=1 has eventually, after 50 minutes, brought: <<< llvm[0]: Compiling glibj.zip to llvm llvm[0]: Optimizing glibj.zip llvm[0]: Compiling glibj.zip.bc to native UNREACHABLE executed! 0 llc 0x0000000000c0e04f 1 llc 0x0000000000c0fc4a 2 libpthread.so.0 0x0000003b6400f0f0 3 libc.so.6 0x0000003b634326c5 gsignal + 53 4 libc.so.6 0x0000003b63433ea5 abort + 373 5 llc 0x0000000000bf07e4 llvm::llvm_unreachable_internal(char const*, char const*, unsigned int) + 356 6 llc 0x00000000008f353d 7 llc 0x00000000008f3614 8 llc 0x00000000008f85e2 9 llc 0x00000000008f894e 10 llc 0x00000000008fa586 llvm::AsmPrinter::EmitGlobalVariable(llvm::GlobalVariable const*) + 550 11 llc 0x00000000008f412f llvm::AsmPrinter::doFinalization(llvm::Module&) + 63 12 llc 0x0000000000ba0369 llvm::FPPassManager::doFinalization(llvm::Module&) + 57 13 llc 0x0000000000ba691f llvm::FPPassManager::runOnModule(llvm::Module&) + 95 14 llc 0x0000000000ba644e llvm::MPPassManager::runOnModule(llvm::Module&) + 462 15 llc 0x0000000000ba655d llvm::PassManagerImpl::run(llvm::Module&) + 125 16 llc 0x000000000051dca0 main + 2672 17 libc.so.6 0x0000003b6341eb1d __libc_start_main + 253 18 llc 0x000000000051bb19 Stack dump: 0.

The unreachable condition was caused by a constant expression involving an inttoptr from i32. This results in a zext to 64 bits, but apparently LowerConstant in AsmPrinter doesn't handle constant expressions involving zext. Aren't zext constant expressions supported by LLVM? - Allan -------------- next part -------------- A non-text attachment was scrubbed...

Hi Allan, Thanks for the fix! So is this a bug in LLVM? Can you reduce that to a small test case and file a bug?
