Bug 35037

Summary:	aarch64: lld не линкует объекты из статических библиотек
Product:	Sisyphus	Reporter:	Vitaly Chikunov <vt>
Component:	lld	Assignee:	Nobody's working on this, feel free to take it <nobody>

Description

Vitaly Chikunov 2018-06-14 11:40:50 MSK

При сборке bcc линкуется большая библиотека libbcc.so. Например, с библиотекой /usr/lib64/libLLVMExecutionEngine.a, которая содержит, например, символ _ZN4llvm20SectionMemoryManagerD2Ev в объекте SectionMemoryManager.cpp.o.

В итоговой libbcc.so символ _ZN4llvm20SectionMemoryManagerD2Ev undefined (как и многие другие). Трейс этого символа при линковке (lld -y _ZN4llvm20SectionMemoryManagerD2Ev) показывает, что lld его не увидел.

Для сравнения "как должно быть" с x86:

  CMakeFiles/bcc-shared.dir/bpf_module.cc.o: reference to _ZN4llvm20SectionMemoryManagerD2Ev
  /usr/lib64/libLLVMExecutionEngine.a(SectionMemoryManager.cpp.o): definition of _ZN4llvm20SectionMemoryManagerD2Ev
  <internal>: reference to _ZN4llvm20SectionMemoryManagerD2Ev

Как есть на aarch64:

  CMakeFiles/bcc-shared.dir/bpf_module.cc.o: reference to _ZN4llvm20SectionMemoryManagerD2Ev

(Команда на линковку примерно одинаковая на обоих архитетурах, либа libLLVMExecutionEngine.a точно есть в обоих.)

Привет!

В сизиф ушел новый llvm 7.0.1 и новый lld, можете проверить с ним?

Я не понял вашего вопроса.

Баг про lld под aarch64.

По i586 это отдельная проблема, поэтому лучше в отдельном баге. Я предполагаю, что это связано с патчем, который заработал в llvm7.0:

Subject: [PATCH] CMake: Split static library exports into their own export                                                                                                                                                                                    
 file                                                                                                                                                                                                                                                         

Summary:                                                                                                                                                                                                                                                      
This is to better support distros which split the static libraries into                                                                                                                                                                                       
their own package.                                                                                                                                                                                                                                            

The current problem is that any project the includes LLVMConfig.cmake                                                                                                                                                                                         
will fail to configure unless the static libraries are installed.  This                                                                                                                                                                                       
is because LLVMConfig.cmake includes LLVMExports.cmake, which throws an                                                                                                                                                                                       
error if it can't find files linked to one of the exported targets.                                                                                                                                                                                           

This patch resolves the problem by putting the static library targets                                                                                                                                                                                         
into their own export file, LLVMStaticExports.cmake.  This file                                                                                                                                                                                               
is optionally included by LLVMConfig.cmake, so distros can put this                                                                                                                                                                                           
new file in their static library package to make  LLVMConfig.cmake                                                                                                                                                                                            
no longer depend on these libraries when they are not installed.

Правильно ли cmake при сборке bcc линкует библиотеки надо смотреть, и, возможно поправить флаги сборки cmake.

Сначала с этим придется разобраться. Но не на НГ.

Ага, это потому что llvm был пересобран clang'ом. Окей, значит это надо где-то отметить.
