f13b47289e * handle case where the first instruction with line information is looked up 
o this should be handled better. The common way is looking up address - 1,
     but that doesn't seem to work here.

0eb9dd3879 * Darwin support for printing line info for backtraces when using Dwarf, 
based on patches by Colin Western, mantis #38483)
   o requires that the program/library is compiled with -Xg (or that
     dsymutil is run on it after compiling), and that the .dSYM bundle
     is in the same directory as the program/library
   o always use the "dl" unit in exeinfo for Darwin, as that's needed for
     dynamic library support, and this does not cause an extra dependency
     since on Darwin we always use libc
   o cleaned up the exeinfo unit for Darwin, and sped it up by using mmap
     instead of small reads
   o fixed unit dependencies for exeinfo, lineinfo and lnfodwarf in Darwin
     RTL Makefile
  * use the process address info from the original exe even when reading
    the debug information from an external file
  - removed outdated ifdef'd darwin code from dl.pp (no longer needed now
    that processaddress gets set correctly in exeinfo for that platform)

d1cdd8be7c * do not emit padding bytes after the dwarf arange header on i8086 for 
compatibility with Open Watcom (also, the dwarf spec is not very clear about
  the alignment requirements on segmented architectures, so that's why we do
  this by default, instead of putting it behind a -go debug switch)
