+ * dwarfextract
+ *
+ *  Extracts the types out of a -g binary (esp. a DEBUG_INFO=y kernel).
+ *  These types can be used by lcrash as its -t or --types ("kerntypes") file.
+ *
+ *  usage: dwarfextract debugkernel kerntypes
+ *
+ *  Based on dwarfdump
+ *    cwickman  5/2005
+ *
+ *  Building this program:
+ *    Build it like you would build dwarfdump. Place this source in the same
+ *    directory as dwarfdump.c (dwarf/dwarfdump/) (tho' it does not depend on
+ *    any parts of dwarfdump, but depends on some of the same header files).
+ *    The dwarfdump/ directory sits next to the libdwarf/ directory.
+ *
+ *  gcc -g -O2 -I. -I./../libdwarf -o dwarfextract dwarfextract.c
+ *       -L../libdwarf -ldwarf -lelf
+ *
+ *  note (6/2005): lcrash depends upon some structures in the kerntypes
+ *   file that may not be in the kernel (they may be, if you grab all modules).
+ *   If you don't extract from the modules you should do a
+ *   "dwarfextract alltypes -c Kerntypes" to add the missing ones from the
+ *   standard Kerntypes file.
+ *
+ *  note: (8/2005)
+ *   for lcrash's benefit, we could create typedef something like this:
+ *   __linux_compile_version_id__uran_Sat_Jul_23_02_20_49_UTC_2005_t
+ *   to identify the version of types file we are creating.
+ *   (else it will complain "types: No version info found!")
+ *
+ *  note: (9/2005)
+ *   a very big -C file has been known to cause a SEGV in realloc() (when
+ *   a malloc'd area being enlarged was initially very big).
+ *   (e.g. INITIAL_NEEDPOINTERS  of 35000 caused the failure when it was
+ *    exceeded.)
+ *   The reason for the failure is still unknown, but the problem went away
+ *   when the initial size guesses were set higher or lower.
+ *
+ *  note: (9/2005)
+ *   extraction from a kernel alone took about 90 seconds
+ *   extraction from a community kernel and 55 modules took about 5 minutes
+ *   extraction from the 2.6 kernel and 1079 modules (sles9) took 2 hours!
