lldb (또는 gdb)를 사용하여 Clang 플러그인을 디버깅하는 방법

Question

Clang 플러그인을 디버깅하고 싶습니다.
그러나 Clang 플러그인의 디버깅에 대한 정보를 찾을 수 없습니다.
Clang 플러그인을 디버깅하는 방법을 알고 있다면 해당 정보를 알려주시겠습니까? 덕분에 .

Answer 1

나는이 자신을 atm 노력하고있어 그냥 작은 개요. 나는 lldb를 사용하고있다.

현재 플러그인의 특정 기능에서 멈출 수 있지만 소스 코드가 없습니다. 어셈블리 만 보여줍니다.

clang을 -Xclang -plugin (...)과 함께 호출하면 하위 프로세스로 분기됩니다. 플러그인을 호출 할 때 -v 옵션을 전달하면 하위 프로세스 명령 줄을 볼 수 있습니다. 그런 다음 디버거에서이 명령 줄을 사용하십시오.

원래 명령 행 :

$> clang++ -Xclang -load -Xclang ${PLUGIN} -Xclang -plugin -Xclang cgd -std=c++11 -w -fsyntax-only -v 

를 출력합니다 :

이제와 lldb를 호출 :

lldb "/srv/scratch/sigubufo/clang/stable/3.1_src/build/bin/clang-3.1" 

그리고 다음 lldb 당신이

(lldb) break set --name YourPlugin::FunctionToBreakAt 

(lldb) process launch -- -cc1 -triple x86_64-unknown-linux-gnu -fsyntax-only -disable-free -main-file-name call_in_if.cpp -mrelocation-model static -mdisable-fp-elim -masm-verbose -mconstructor-aliases -munwind-tables -target-cpu x86-64 -momit-leaf-frame-pointer -v -resource-dir /srv/scratch/sigubufo/clang/stable/3.1_src/build/bin/../lib/clang/3.1 -fmodule-cache-path /var/tmp/clang-module-cache -internal-isystem /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../include/c++/4.6 -internal-isystem /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../include/c++/4.6/x86_64-linux-gnu -internal-isystem /usr/lib/gcc/x86_64-linux-gnu/4.6/../../../../include/c++/4.6/backward -internal-isystem /usr/local/include -internal-isystem /srv/scratch/sigubufo/clang/stable/3.1_src/build/bin/../lib/clang/3.1/include -internal-externc-isystem /usr/include/x86_64-linux-gnu -internal-externc-isystem /include -internal-externc-isystem /usr/include -Werror -w -std=c++11 -fdeprecated-macro -fdebug-compilation-dir /srv/scratch/sigubufo/danceos_wd/clang/qtcreator-build -ferror-limit 19 -fmessage-length 205 -mstackrealign -fgnu-runtime -fobjc-runtime-has-arc -fobjc-runtime-has-weak -fobjc-fragile-abi -fcxx-exceptions -fexceptions -fdiagnostics-show-option -fcolor-diagnostics -load lib/CallGraphDumper.so -plugin cgd -x c++ ../test_cases/call_in_if.cpp
