for Sun acc 3.0 under SunOS4.
Changes to improve handling of runtime common symbols
under SunOS4.
* minsyms.c (get_symbol_leading_char): New routine to determine
the leading symbol character for an objfile.
(prim_record_minimal_symbol_and_info, install_minimal_symbols):
Use it.
* objfiles.h (rt_common_objfile): New global, points to objfile
containing the runtime common minimal symbols.
* objfiles.c (free_objfile): Mark rt_common_objfile as
unallocated before freeing it.
* solib.c (allocate_rt_common_objfile): New routine to allocate
an objfile for the runtime common minimal symbols.
(solib_add_common_symbols): Allocate an objfile for the runtime
common symbols if necessary and put common symbols into it.
Clean up code and comments.
(solib_add, special_symbol_handling): Cleanup comments regarding
runtime common symbols.
* stabsread.c (scan_file_globals_1): New routine, contains
old scan_file_globals code. Checks if there are any unresolved
global symbols before starting the expensive minimal symbol table
search.
(scan_file_globals): Now calls scan_file_globals_1 for the passed
objfile and eventually for the runtime common objfile. Complains
about any unresolved global symbols and removes them from the
global symbol chain to avoid dangling pointers into the symbol
table if the symbol table is reread.
symbol_completion_function, takes the line buffer and the
point in the line buffer as additional arguments.
(readline_line_completion_function): New function, interface
between readline and line_completion_function.
(init_main): Use it.
(complete_command): Use line_completion_function instead of
abusing rl_line_buffer. Free completion strings after printing
them.
* symtab.c (completion_list_add_name): Recheck for duplicates
if we intend to add a modified symbol.
* gdbtypes.h (cplus_struct_type): nfn_fields_total no longer
includes the number of methods from the baseclasses.
* stabsread.c (attach_fn_fields_to_type): No longer add the
number of methods from the baseclasses to TYPE_NFN_FIELDS_TOTAL,
the baseclass type might not have been completely filled in yet.
* symtab.c (total_number_of_methods): New function to compute
the total number of methods for a type, including the methods
from baseclasses.
(decode_line_1): Use it instead of TYPE_NFN_FIELDS_TOTAL to
allocate the symbol array for find_methods.
* stabsread.c (scan_file_globals): Add default case to minimal
symbol type switch, to avoid gcc -Wall warnings.
* config/rs6000/tm-rs6000.h (INIT_EXTRA_FRAME_INFO):
Don't test for zero backchain pointer to recognize a signal
handler frame, if read() gets interrupted by a signal, the
backchain will be non zero.
(SIG_FRAME_FP_OFFSET): Move to here from rs6000-tdep.c,
improve comment.
(SIG_FRAME_PC_OFFSET): New definition.
(FRAME_SAVED_PC): Return saved pc from sigcontext if this
is a signal handler frame.
* rs6000-tdep.c (function_frame_info): Do not error out
if we can't access the instructions.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR):
New definition to get the function address from a function pointer.
* valops.c (find_function_addr): Use it when calling a user
function through a function pointer.
define TARGET_BYTE_ORDER as target_byte_order, and declare
target_byte_order as an extern int, and define BITS_BIG_ENDIAN as
a test of TARGET_BYTE_ORDER.

defined:
(endianlist, target_byte_order): New variables.
(set_endian, set_endian_big, set_endian_little): New functions.
(show_endian): New function.
(init_cmd_lists): Initialize endianlist.
(init_main): Add commands ``set endian big'', ``set endian
little'', and ``show endian''.

BITS_BIG_ENDIAN to switch at run time rather than at compile time.
* coffread.c, dwarfread.c, findvar.c, mips-tdep.c: Likewise.
* remote-os9k.c, stabsread.c, valarith.c, valprint.c: Likewise.
* values.c: Likewise.
* mips-tdep.c: Rewrite uses of GDB_TARGET_IS_MIPS64 to switch at
run time rather than at compile time.
* ch-typeprint.c, ch-valprint.c: Use TYPE_INDEX_TYPE.
* ch-valprint.c (chill_val_print): Pass index type directly
(instead of its TYPE_TARGET_TYPE) to print_type_scalar.
* stabsread.c (read_type): Don't set TYPE_FLAG_TARGET_STUB
if the index type is a stub.
* stabsread.c (read_array_type): Check for stub domain type
using TYPE_FLAG_STUB, not its length.
* gdbtypes.c (create_set_type): Handle a stub domain type.
if a '(' is found in varstring, Looking for ')' at the end of
varstring did fail with demangled const member functions, which
have a trailing `const'.
* remote.c (get_offsets, putpkt): Change to `char' buffers,
to avoid errors when compiling with DEC c89.
(remote_wait): Cast to `char *' before passing buffer to
fputs_filtered, to avoid errors when compiling with DEC c89.
(remote_wait): Do not return inferior_pid by default, this
statement is never reached, which causes warnings from some
compilers.
* stabsread.c (scan_file_globals): Ignore static minimal symbols.
* symfile.c (load_command): If called with no argument, try
to get the filename from the executable file.
(generic_load): Remove check for NULL filename, it is done

level, and make the latter non-static (so define_symbol can use it).

pointer type named "__vtbl_ptr_type", set the TYPE_NAME to that name.

without interpreting that to mean "adjustable."

ChangeLog stabsread.c
* stabsread.c (patch_block_stabs, define_symbol, read_type): in
g++ template instantiation, nested class can be part of the

struct/union/enums and typedefs.

visibility character, just shove it in fip->list->visibility.
(read_baseclasses): Don't give up on unknown virtual or visibility
characters, just assume a reasonable default, complain, and keep
going.
(attach_fields_to_type): Complain on unrecognized visibility.
One result of all this is that '9' (VISIBILITY_IGNORE) can be used
in a stab as well as being something which GDB uses internally.
gdbtypes.h stabsread.c cp-valprint.c ChangeLog
* gdbtypes.h : add a field 'ignore_field_bits in cplus_specific,
and macros to handle the bits.
* stabsread.c (read_one_struct_field): add VISIBILITY_IGNORE, and
for field of length 0, set this bit on.
* cp-valprint.c (cp_print_value_fields): for VISIBILITY_IGNORE
field, print <no value>.
* Move SWAP_TARGET_AND_HOST from defs.h to findvar.c because it is
now used only by extract_floating and store_floating.
* valprint.c (print_floating): Use unsigned arithmetic. Use
extract_unsigned_integer instead of SWAP_TARGET_AND_HOST.
Change sizeof (float) to 4 and sizeof (double) to 8 (those are always
the relevant sizes for this code, which is in #ifdef IEEE_FLOAT).
* values.c (unpack_long, unpack_double, value_from_double),
valarith.c (value_binop), stabsread.c (define_symbol):
Use extract_floating and store_floating instead of
SWAP_TARGET_AND_HOST.
* config/m68k/tm-m68k.h, config/i960/tm-i960.h (REGISTER_CONVERT_*):
Use extract_floating and store_floating.
* config/m88k/tm-m88k.h: Add comments (it should be doing the same).
* i386-tdep.c (i386_extract_return_value),
* remote-nindy.c (nindy_store_registers): Use store_floating.
