+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.
