* The following block of changes add support for debugging assembly
source files.
* breakpoint.c (resolve_sal_pc): Prevent crash when pc isn't
associated with a function.
* buildsym.c (record_line start_symtab end_symtab): Don't delete
symtabs which only have line numbers (but no other debug symbols).
* dbxread.c (read_dbx_symtab end_psymtab): Ditto.
* remote-sim.c: New functions gdbsim_insert/remove_breakpoint. Use
intrinsic simulator breakpoints if available, otherwise do it the
hard way.
* configure.tgt: Add d30v.
* d30v-tdep.c: New file.
* config/d30v/d30v.mt, config/d30v/tm-d30v.h: New files.
