Re: [lldb-dev] Code Coverage with GCOV

2016-08-17 Thread Vedant Kumar via lldb-dev 
Is it possible that the files are written to an unexpected directory? Have you
tried running the program under strace/dtruss to conclusively determine whether
or not the files are being written? Could you try running lldb-server in lldb
and setting a breakpoint on `llvm_gcda_start_file'?

Re: [lldb-dev] Code Coverage with GCOV

2016-08-17 Thread Ravitheja Addepally via lldb-dev 
Hello,
   I added the following lines to the lldb-server and lldb
CMakeLists.txt
   set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fprofile-arcs -ftest-coverage")
   set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fprofile-arcs
-ftest-coverage")

I am able to get the lldb-server gcov files when I start its instance and
then connect to it. But since lldb starts the lldb-server in different way,
the files are not written, because I do see that the gcov instrumentation
functions are present in the lldb-server.

[lldb-dev] Code Coverage with GCOV

2016-08-16 Thread Ravitheja Addepally via lldb-dev 
Hello,
   I was trying to get Code Coverage for LLDB with GCOV on Linux by
adding the corresponding flags in the CMake files, but I am facing problem
with lldb-server, which does not give seem to generate the gcda files. The
host side does generate the gcov files although. The lldb-server does
generate the gcov files if it is started in Standalone mode but it does not
generate the gcov files if started by LLDB. Has anyone tried this already ?
How can I get Code Coverage for lldb / lldb-server on Linux ?
