I've recently posted a patch to translate ARM's delay.S in arch/arm/lib into a C file[1]. This works fine and I can build the tree with the .S file and then build the tree with the .C file. After I do that I can't switch back to the .S version of the tree without first removing the .delay.o.cmd file in my build output directory. It seems that the build system can't recognize when a C file turns into an assembly file. Anyone else seen this problem? I admit it is pretty rare, but it becomes annoying with things like automated building, bisecting, etc. where I don't make clean all the time.
