> It is almost magical changing a linker flag in some bazel config and see it _only_ relink affected targets. I think this should be expected from any modern build system. Now, if you make a whitespace change in your source file and the build system recognized this and skips recompiling it, that could pass for magic (build2 does this for C/C++ sources).

If the output .o is identical then I think bazel will also skip recompilation, FWIW.

  You probably mean relinking: to compare old .o to new, you would need to recompile the source file to get the new .o.

    Yes, that's what I meant.
