Added a small + comment (hopefully useful) to dwarf_alloc.h. + + And now deals correctly with a null dbg on + DW_DLA_ERROR due to failed + dwarf_init() call (or due to other error in calling + libdwarf that results in libdwarf not knowing the dbg, + a likely far more common case) and frees the memory. + This used to result in chaos (depending on your + luck...). + +2000 Aug 23 davea@sgi.com + libdwarf2.1.mm, ps. Failed to mention that dwarf_finish() + has to be accompanied by elf_end() if dwarf_init() was used + to initialize libdwarf to truly release all stuff. + Added text to dwarf_finish() describing how to do that. +2000 April 14 davea@sgi.com + + dwarf_abbrev.c - 1.22 + - When it is a null abbrev entry, return it correctly so it can be + printed (meaning fill out all the return-parameters so the caller can + do the right thing). + + dwarf_init_finish.c - 1.48 + - For most sections, simply having an empty section (present but empty) + is just fine.
