Wasn't that fixed in GAS? https://sourceware.org/bugzilla/show_bug.cgi?id=27195$ make LLVM=1 -j72 defconfig $ ./scripts/config -e DEBUG_INFO -e DEBUG_INFO_DWARF5 $ make LLVM=1 -j72 ... /tmp/init-d50d89.s: Assembler messages: /tmp/init-d50d89.s:10: Error: file number less than one /tmp/init-d50d89.s:11: Error: junk at end of line, first unrecognized character is `m' which is https://sourceware.org/bugzilla/show_bug.cgi?id=25611. $ as --version | head -n1 GNU assembler (GNU Binutils for Debian) 2.35.1 Maybe GAS should not need to be told -gdwarf-5 to parse these? Then we would not need to pass -Wa,-gdwarf-5 via clang with -no-integrated-as.
That is what sw#27195 is about, just try current binutils 2.35, 2.36 or trunk branches. Jakub
