I am trying to make a modification to gcc compiler and rebuild the compiler under bitbake.
I can bitbake gcc and see the file in ./tmp/work-shared/gcc-4.8.2-r0/gcc-4.8.2/libstdc++-v3/src/c++11/thread.cc
After modifying thread.cc and changing the PR number in the recipe, the change made in thread.cc is overwritten.
Can you provide what are the proper steps to make a source change to gcc compiler?
Note. devtool isn't available. Therefore, I am try to determine how best to make a change in gcc compiler source for debug purposes only and build the load using bitbake.
