[llvm-dev] Can I build llvm with only a handful of source files compiled for debug?

Clang has a way to achieve this. Once you've built LLVM without debug info, you can then delete the objects or modify the sources you want to debug and then rebuild with something like 'CCC_OVERRIDE_OPTIONS="+-g +-O0" ninja'. The newly built files will have debug info.

This will reduce the load on the file system, linker and gdb tremendously.  At present, AFAICT, it's all or nothing.
