[llvm-dev] OpenJDK8 failed to work after compiled by LLVM 8 for X86
Hi Dimitry, Thanks for your kind response! Thanks for the commit message of Jung's patch, I found that the bug had been fixed in OpenJDK 12 by Zhengyu https://bugs.openjdk.java.net/browse/JDK-8205965 But only backported to 11. So Jung could backport it for OpenJDK 8, thanks a lot! But I argue that the root cause might be in the compiler side, why clang-3.9.1, gcc-6.4.1 couldn't reproduce the bug? And it might be work for clang-4.0 https://bugs.openjdk.java.net/browse/JDK-8208494 I will test LLVM 5 to check out whether or not reproducible. 在 2018年09月11日 00:59, Dimitry Andric 写道:> Hi Leslie, > > This is likely the same problem as was reported in https://bugs.freebsd.org/225054#c8, and fixed by the following patch: > > https://svnweb.freebsd.org/ports/head/java/openjdk8/files/patch-hotspot_src_share_vm_services_memTracker.cpp?view=markup&pathrev=459368 > > Can you please try that out, and see if it fixes it for you too? > > -Dimitry > >> On 10 Sep 2018, at 18:20, Leslie Zhai via llvm-dev <llvm-dev at lists.llvm.org> wrote: >> >> Hi all, >> >> OpenJDK8 jdk8u-dev[1] is just able to work after compiled with LLVM 3.9.1 for X86: >> >> $ ./build/linux-x86_64-normal-server-slowdebug/images/j2sdk-image/bin/java -version >> openjdk version "1.8.0-internal-debug" >> OpenJDK Runtime Environment (build 1.8.0-internal-debug-xiangzhai_2018_09_09_21_08-b00) >> OpenJDK 64-Bit Server VM (build 25.71-b00-debug, mixed mode) >> >> $ strings ./build/linux-x86_64-normal-server-slowdebug/images/j2sdk-image/bin/java | grep clang >> clang version 3.9.1 (tags/RELEASE_391/final) >> >> But it failed to work after compiled with LLVM 8 for X86: >> >> $ ./build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java -version >> Segmentation fault >> >> $ gdb --ex run --args ./build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java -version >> GNU gdb (GDB) Fedora 7.12.1-48.fc25 >> ... >> Starting program: /home/xiangzhai/project/jdk8u-llvm/build/linux-x86_64-normal-server-fastdebug/images/j2sdk-image/bin/java -version >> [Thread debugging using libthread_db enabled] >> Using host libthread_db library "/lib64/libthread_db.so.1". >> >> Program received signal SIGSEGV, Segmentation fault. >> [ Legend: Modified register | Code | Heap | Stack | String ] >> ───────────────────────────────────────────────────────────────────────────────────────────────[ registers ]──── >> $rax : 0x0 >> $rbx : 0x0 >> $rcx : 0x7ffff7315eb0 → 0x00007ffff6ae30a0 → <NativeCallStack::print_on(outputStream*)+0> xor edx, edx >> $rdx : 0x0 >> $rsp : 0x7fffffff9328 → 0x00007ffff6a76822 → <MemTracker::init_tracking_level()+178> mov edi, ebx >> $rbp : 0x7fffffff93c0 → 0x00007fffffff94f0 → 0x00007fffffff9510 → 0x0000000000000002 >> $rsi : 0x0 >> $rdi : 0x7ffff7315e70 → 0x00007ffff7315eb0 → 0x00007ffff6ae30a0 → <NativeCallStack::print_on(outputStream*)+0> xor edx, edx >> $rip : 0x7ffff6ae2f5b → <NativeCallStack::NativeCallStack(int,+0> mov QWORD PTR [rdi], rcx >> $r8 : 0x1 >> $r9 : 0xf >> $r10 : 0x64 >> $r11 : 0x0 >> $r12 : 0x7fffffffdc88 → 0x00007fffffffe04c → "/home/xiangzhai/project/jdk8u-llvm/build/linux-x86[...]" >> $r13 : 0x7fffffffdca0 → 0x00007fffffffe0bf → "XDG_VTNR=1" >> $r14 : 0x7fffffff9330 → "NMT_LEVEL_10535" >> $r15 : 0x6 >> $eflags: [carry parity adjust zero sign trap INTERRUPT direction overflow RESUME virtualx86 identification] >> $ss: 0x002b $ds: 0x0000 $cs: 0x0033 $es: 0x0000 $gs: 0x0000 $fs: 0x0000 >> ───────────────────────────────────────────────────────────────────────────────────────────────────[ stack ]──── >> 0x00007fffffff9328│+0x00: 0x00007ffff6a76822 → <MemTracker::init_tracking_level()+178> mov edi, ebx ← $rsp >> 0x00007fffffff9330│+0x08: "NMT_LEVEL_10535" ← $r14 >> 0x00007fffffff9338│+0x10: 0x0035333530315f4c ("L_10535"?) >> 0x00007fffffff9340│+0x18: 0x0000000000000001 >> 0x00007fffffff9348│+0x20: 0x0000000000602190 → 0x00007ffff5eb7000 → 0x00010102464c457f >> 0x00007fffffff9350│+0x28: 0x0000000000000004 >> 0x00007fffffff9358│+0x30: 0x000000066474e551 >> 0x00007fffffff9360│+0x38: 0x0000000000000000 >> ────────────────────────────────────────────────────────────────────────────────────────[ code:i386:x86-64 ]──── >> 0x7ffff6ae2f4b <print_owned_locks_on_error(outputStream*)+187> add eax, 0x1f0f00 >> 0x7ffff6ae2f50 <NativeCallStack::NativeCallStack(int,+0> mov rcx, QWORD PTR [rip+0x842781] # 0x7ffff73256d8 >> 0x7ffff6ae2f57 <NativeCallStack::NativeCallStack(int,+0> add rcx, 0x10 >> → 0x7ffff6ae2f5b <NativeCallStack::NativeCallStack(int,+0> mov QWORD PTR [rdi], rcx >> 0x7ffff6ae2f5e <NativeCallStack::NativeCallStack(int,+0> mov DWORD PTR [rdi+0x28], 0x0 >> 0x7ffff6ae2f65 <NativeCallStack::NativeCallStack(int,+0> add rdi, 0x8 >> 0x7ffff6ae2f69 <NativeCallStack::NativeCallStack(int,+0> test edx, edx >> 0x7ffff6ae2f6b <NativeCallStack::NativeCallStack(int,+0> je 0x7ffff6ae2f7b <NativeCallStack::NativeCallStack(int, bool)+43> >> 0x7ffff6ae2f6d <NativeCallStack::NativeCallStack(int,+0> mov eax, esi >> ─────────[ source:/home/xiangzhai/project/jdk8u-llvm/hotspot/src/share/vm/utilities/nativeCallStack.cpp+33 ]──── >> 28 #include "utilities/nativeCallStack.hpp" >> 29 >> 30 const NativeCallStack NativeCallStack::EMPTY_STACK(0, false);
