Wed Sep 28 00:35:23 1994  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c (hpread_read_array_type): Do not change the type code
	to TYPE_CODE_PTR for "char foo[]".  Just make it a zero length
	array type.

	* hpread.c (hpread_type_translate): Handle T_UNS_LONG types with
	lengths other than 32bits (HP C 9.69 represents an "unsigned char"
	as an T_UNS_LONG with length 8).

	* hpread.c (struct hpread_symfile_info): Delete have_module field
	and accessor macro.  Minor indentation fix.
	(hpread_build_psymtabs, case K_MODULE):  Only start a new psymtab
	and reset state variables have_name & texthigh if pst is NULL.
	(hpread_build_psymtabs, case K_SRCFILE): Only reset the name of a
	partial symbol table if pst is non-NULL.  If pst is NULL, then
	start a new psymtab.
	(hpread_process_one_debug_symbol, case K_MODULE): Now empty.
	(hpread_process_one_debug_symbol, case K_SRCFILE): Simplify and
	correct handling of subfiles.

Fri Aug 19 10:36:15 1994  Jeff Law  (law@snake.cs.utah.edu)

	* 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
	private data to zero.  Not having any HP C debug symbols is not an
	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)

	* hpread.c (_initialize_hpuxread): Don't call add_symtab_fns if
	HPREAD is not defined.

Sun Mar 13 17:19:03 1994  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c (read_hpux_symtab: Correctly determine the namespace
	and address class of SVAR, DVAR, TYPEDEF, TAGDEF, CONST, and
	MEMENUM symbols.  Do not include function-scoped variables in
	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
	access BFD private data.  Search for the "$TEXT$" space rather
	than ".text".
	(hppa_sym_fns): Add bfd target flavour to initializer.

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

	* hpread.c (read_hp_function_type): Correctly handle
	pass-by-value structures > 64bits in size.
	(process_one_debug_symbol): Likewise.

Tue Nov  2 03:01:01 1993  Jeff Law  (law@snake.cs.utah.edu)

	 * hpread.c: Include <time.h> and <sys/types.h>.  Change include
	 of "libhppa.h" to "som.h".
	 (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)

	K_MODULE, clear the have_module and have_name flags.

Sun Aug 22 22:50:32 1993  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c (get_textlow): Don't go past a K_END when looking for a
	K_FUNCTION.  Avoids losing on source files with no functions. 

Wed Aug 18 21:42:52 1993  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c (read_hpux_symtab): Call SET_NAMESTRING for K_MODULE
	debug symbols.

Mon Aug 16 09:52:33 1993  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c: Add U Utah contribution notice.  Add TODO list.
	(hp_type_lookup): Use TYPE_NAME and TYPE_TAG_NAME.
	(process_one_debug_symbol): Likewise.

Tue Jul 20 14:14:59 1993  Jeff Law  (law@snake.cs.utah.edu)

Mon Jun 28 19:00:21 1993  Jeff Law  (law@snake.cs.utah.edu)

	* hpread.c: Do not include libhppax.  Instead include libhppa.h
	and hpux-symtab.h.  Misc indention fixes.
	(find_unwind_entry): Add PARAM prototype.
	(read_hpux_symtab): More fixes for names and sizes of structs,
	unions, enums, typedefs, and tagdefs.
	(read_hp_enum_type, read_hp_struct_type): Likewise.
	(read_hp_set_type, read_hp_subrange_type): Likewise.
	(hp_type_lookup, process_one_debug_symbol): Likewise.
	(process_one_debug_symbol): Search forward from the K_FUNCTION for
	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
	copyright to reflect the first "release" of this file.

	(read_hpux_symtab): Delete KERNELDEBUG crud.  Ignore debug symbols
	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.

	SYMBOL_INIT_DEMANGLED_NAME for the current symbol.  Adjust

	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
	arguments in the stack by the size of the current function's stack
	(found in the unwind descriptor).
	(process_one_debug_symbol): Likewise.  Keep track of the current
	function's unwind descriptor.
