Last change on this file since 9ded977 was 9ded977, checked in by Martin Decky <martin@…>, 15 years ago

add initial support for line debugging information and generating disassembly outputs with source code intermixed (useful for analyzing of stack traces)
currently the disassembly and source is intermixed only in the case of amd64 kernel (other linker scripts strip the debugging sections so far)
  • Property mode set to 100644
