+Mon Dec 23 13:54:35 1991  Per Bothner  (bothner at cygnus.com)
+
+       * m68k-opcode.h, mips-opcode.h, sparc-opcode.h:  Deleted.
+       * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
+       Include <opcode/FOO.h> instead of <FOO-opcode.h>.
+
+       * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
+       dbxread.c:  The TYPE_CPLUS_SPECIFIC structure is now only
+       allocated when it is needed.  Until it is needed, it points
+       to a shared statically allocated structure.
+
+       * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
+       in read_ofile_symtab to recognize two initial N_SO stabs,
+       and let process_on_symbol handle it.  This is cleaner, more
+       efficient, and lets mipsread.c share the same code.
+
+       * symfile.h, partial-stab.h:  Move ADD_PSYMBOL_VT_TO_LIST
+       and related macros to here ...
+       * dbxread.c: ... from here.
+       * symmisc.c:  Move the "overflow" handling from
+       ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
+       * dwarfread.c:  Re-write add_psymbol_to_list to use
+       ADD_PSYMBOL_VT_TO_LIST macro.
+
+       * mipsread.c: Extend mipsread.c to handle stabs-style symbols
+       encapsulated in ecoff symbols.  This enable full g++ debugging.  
+       * partial-stab.h:  Move the code for pre-scanning symbols
+       and building psymtabs to an include file, out from dbxread.c.
+       This way, the same code can also be used by mipsread.c.
+       * dbxread.c, buildsym.h:  Various changes to allow some functions
+       to be used by mipsread.c (also some arguable stylistic changes).
+
+       * tm-mips.h:  Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
+       since mips-tfile puts relocatable addresses into LBRAC/RBRAC
+       stabs.
+
+       * mipsread.c:  Replace code to handle ambiguous tag blocks.
+       Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
+       at types and offsets) if a tag is a struct, union, or enum.
+       Still patch it later if we find out for sure.
+       * mipsread.c:  In various ways, replace Forin's
+       ideo-syncratic code by code that fits better with the
+       rest of gdb, for both stabs-based and ecoff-based symtabs.
+       E.g.  use end_psymtab; don't do extra passes over FDR table to
+       pre-partition global data; don't use external symbols to
+       create static/global symbols (just put them in the
+       misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
+       sort psymtabs or symtabs; use obstacks more.
+
+       * symtab.c, mipsread.c, dbxread.c, buildsym.c:
+       ANSIfy: Replace bcopy by memcpy, bzero by memset.
