That looks suspicious. > These are the assembly files, so yes the file is completely useless if not compiling for 64bit x86, but CONFIG_ATADENOISE_FILTER is correctly set as we still want to pull in the standard c files. Basically inside these files is a chunk of code inside a ARCH_X86_64 idef so when compiling for a different arch the files end up containing nothing. So apart from just saving some compilation effort not compiling files that dont contain any usable code, this also showed up as an issue under certain circumstances as nasm in win64 would generate output for essentially empty files like these that breaks the msvc linker.
