+
+ * Makefile.in (ALLDEPFILES): Add hpread.c.
+ (hpread.o): Add dependencies.
+
+ * somread.c: Do not include "aout/aout64.h". SOM has nothing to
+ do with a.out.
+ (BYTES_IN_WORD): Delete.
+ (som_symfile_read): Call hpread_build_psymtabs to build any
+ minimal symbols based on the HP C native debug symbols.
+ (som_symfile_finish): Call hpread_symfile_finish.
+ (som_symfile_init): Call hpread_symfile_init.
+ * config/pa/tm-hppa.h (HPREAD_ADJUST_STACK_ADDRESS): Define.
+ * hppa-tdep.c (hpread_adjust_stack_address): New function.
+
+ * config/pa/hppabsd.mh (NATDEPFILES): Add hpread.o
+ * config/pa/hppahpux.mh (NATDEPFILES): Likewise.
+ * hpread.c: New file.
+
+Fri Aug 12 19:30:53 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c: Delete rest of TODO list. Do not include "libbfd.h",
+ <time.h>, <sys/types.h>, "demangle.h", <sys/file.h>,
+ "expression.h", "language.h", "gdbtypes.h", "demangleh".
+ Move all global variables into the private symbol table structure
+ and add accessor macros. Update some comments.
+ (hpread_build_psymtabs): Delete dbsubc_addr, we don't need it.
+ (hpread_end_psymtab): New function to end a partial symbol table,
+ all callers changed (no more bogus sharing with dbxread.c).
+
+Mon Aug 08 15:34:13 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c (hpread_process_one_debug_symbol): Fix block scoping
+ problem (losing localvars on the close-brace instead of after
+ the close brace).
+
+Wed Jul 06 12:39:07 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c: More cleanups. Delete lots of trailing whitespace.
+ Remove some items from the TODO list and notes throughout code
+ for things which need fixing. Add more comments.
+ Document bogus struct symloc sharing with dbxread.c. Delete more
+ useless variables. Add more PARAM prototypes. Fixup more
+ indention problems that have crept in.
+ (SET_NAMESTRING): Accept new namep and objfile arguments so that
+ it doesn't depend on the variable names on the procedures it's
+ used from.
+ (hpread_symfile_init): Delete incorrect checks for bogus sizes of
+ the debug sections.
+
+Mon Jul 04 19:48:03 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c (hpread_symfile_init): Make sure to initialize all the

+ error. Just return.
+
+Fri Jul 01 19:50:21 1994 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c: Change contribution notice to the Cygnus/Utah agreed
+ upon notice. Delete some stuff from the TODO list. Rework
+ many comments to be clearer. Major cleanups. Consistently
+ use "hpread_" prefix. Delete unnecessary macros, structures
+ variables, fiels, functions and #if 0 code. Mark code which
+ still needs to be cleaned up. PARAMize and make most functions
+ static. Fix error checking when reading in the debug section
+ contents. No more minimal symbol table handling in this code!
+
+Mon Mar 21 10:09:06 1994 Jeff Law (law@snake.cs.utah.edu)

+ the partial symbol table.
+
+Sun Feb 6 15:56:09 1994 Jeff Law (law@wild.cs.utah.edu)
+
+ * hpread.c (hpux_symfile_init): Use obj_som_* rather than obj_* to

+
+Thu Dec 16 09:14:58 1993 Jeff Law (law@snake.cs.utah.edu)

+ (BYTES_IN_WORD): Define.
+ (hppa_sym_fns): "hppa" is 4 characters, not 5.
+
+Wed Sep 29 17:20:54 1993 Jeff Law (law@snake.cs.utah.edu)

+ the first K_BEGIN when setting the line number associated with a
+ function. Avoid unnecessary calls to savestring.
+ (hp_alloc_type): Initialize TYPE_CPLUS_SPECIFIC here. Remove
+ most cases where we set it elsewhere.
+ (hppa_sym_fns): Use "hppa" instead of hppax since hpread.c and
+ paread.c use the same BFD backend now. All references changed.
+ (hpux_symfile_init): Allocate space to hold the debugging section
+ contents on the symbol obstack.
+
+Wed Jun 23 16:33:36 1993 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c: Document a few functions, misc cleanups. Update

+ which are not needed for building partial symbol tables. Handle
+ K_CONST, K_TYPEDEF, and K_TAGDEF just like K_SVAR and K_DVAR.
+ (read_ofile_symtab): Delete useless processing_gcc_compilation stuff.
+ (read_hp_struct_type): Initialize TYPE_CPLUS_SPECIFIC.
+ (read_hp_set_type, read_hp_array_type): Likewise.
+ (read_hp_subrange_type, hp_type_lookup): Likewise.
+
+Tue Jun 22 11:03:13 1993 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c: Delete useless #if 1 statements.
+ (hp_type_translate): Use T_LONG, T_UNS_LONG, and T_DOUBLE instead
+ of magic integers. Fix handling for T_UNS_INT. Abort if the type
+ passed in is not an "immediate" type.
+ (read_hp_enum_type): Properly compute the size of the type.
+ (read_hp_array_type): Likewise.
+ (hp_type_lookup): Prefix the names of structs, unions and enums

+
+ * hpread.c: Include "demangle.h".
+ (process_one_debug_symbol): Set the SYMBOL_LANGUAGE and
+ SYMBOL_INIT_DEMANGLED_NAME for the current symbol. Adjust
+ SYMBOL_VALUE for local variables in the stack by the size of the
+ current function's stack (found in unwind descriptor). Keep
+ better track of the current unwind descriptor.
+
+Wed Jun 16 14:34:10 1993 Jeff Law (law@snake.cs.utah.edu)
+
+ * hpread.c (hp_type_translate): Fix promotion bugs from
+ char to short and short to int.

+
+ * hpread.c (read_hp_function_type): Adjust SYMBOL_VALUE for
