No, there *is* line info there, carried over from an earlier .loc directive, as there isn't anything like ".noloc" to output with a function that is not expected or supposed to have line number info. Without that, the assembler just extends the previous .loc directive onto the function. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer Vim, Vi, Voltei pro Emacs -- GNUlius Caesar
