36a2283dad Add partial support for g++ code compiled with -fvtable-thunks.
* c-valprint.c (c_val_print):  Add vtblprint support
	when using thunks.
	* cp-valprint.c (cp_is_vtbl_member):  A vtable can be an array of
	pointers (if using thunks) as well as array of structs (otherwise).
	* cp-valprint.c (vtbl_ptr_name_old, vtbl_ptr_name):  Move to global
	level, and make the latter non-static (so define_symbol can use it).
	* stabsread.c (define_symbol):  If the type being defined is a
	pointer type named "__vtbl_ptr_type", set the TYPE_NAME to that name.
	* symtab.h (VTBL_PREFIX_P):  Allow "_VT" as well as "_vt".
	* values.c (value_virtual_fn_field):  Handle thunks.
	* values.c (value_headof):  Minor efficiency hack.
	* values.c (value_headof):   Incomplete thunk support.  FIXME.

a66e8382de * dbxread.c (record_minimal_symbol): Record the section
associated with the symbol to make dynmaic relocation work.
	* (dbx_symfile_read, process_one_symbol):  Fixes to work around
	Solaris brain-damage which don't apply to relocatable object
	files.
	* (stabsect_build_psymtabs):  New routine to read stabs out of an
	arbitrarily named section.
	* nlmread.c (nlm_symtab_read):  Read ALL syms from the NLM, not just
	globals.
	* (nlm_symfile_read):  Call stabsect_build_psymtabs to read the
	stabs out of the nlm.
	* partial-stabs.h (cases 'f' & 'F'):  Fixes to work around Solaris
	brain-damage which don't apply to relocatable object files.
	* remote.c (putpkt):  Improve error reporting and error handling.
	* stabsread.c (define_symbol, scan_file_globals):  Record section
	info in sym.

84ad95c118 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
for the structure's type.  All callers changed.

        * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR

        true or false for all structure arguments.

dda398c369 * gdbtypes.h: Add TYPE_FLAG_TARGET_STUB.
* gdbtypes.c (check_stub_type): On TYPE_FLAG_TARGET_STUB, do
	what cleanup_undefined_types does for arrays, except we clear
	TYPE_FLAG_TARGET_STUB if we fix up the type.
	* stabsread.c (cleanup_undefined_types): Add comments about how
	doing arrays here is no longer the clean way to do it.
	(read_array_type): Set TYPE_FLAG_TARGET_STUB as well as calling

	* c-typeprint.c, ch-typeprint.c: Move call to check_stub_type
	outside switch so it happens for all type codes.
	* cp-valprint.c (cp_print_value_fields): Recurse to val_print,
	instead of c_val_print, so that check_stub_type gets called.

	* gdbtypes.h, gdbtypes.c, m2-lang.c, ch-lang.c, c-lang.c: Remove
	TYPE_FLAG_SIGNED.  It was inconsistently set, never checked
	(except in recursive_dump_type), and is pointless.

	characters, just assume a reasonable default, complain, and keep
	going.

	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.

1993-10-31 20:45:41 +00:00
Jim Kingdon
bf5c0d6448 * defs.h, findvar.c (extract_floating, store_floating): New functions.
* Move SWAP_TARGET_AND_HOST from defs.h to findvar.c because it is

	* 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).

4fc9d7c70e * stabsread.c (read_type): Treat a negative type number at the start

	"50=" omitted.  This makes things work on the RS/6000 again (the
	14 Sep 1993 change broke it).

	Allocate things on the symbol_obstack.

	* breakpoint.c (breakpoint_auto_delete):  Delete only if we really
	stopped for the breakpoint.
	* stabsread.c, stabsread.h (define_symbol):  Change valu parameter
	to a CORE_ADDR.
	* stabsread.c (read_range_type):  Handle the case where the lower
	bound overflows and the upper doesn't and the range is legal.
	* infrun.c (resume):  Do not step a breakpoint instruction if
	CANNOT_STEP_BREAKPOINT is defined.

	* inferior.h (CALL_DUMMY_LOCATION):  New variant AT_ENTRY_POINT.
	Now that we have the bp_call_dummy breakpoint the call dummy code
	is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and
	FIX_CALL_DUMMY can be used to set up everything for the dummy.
	The breakpoint for the dummy is set at the entry point and thats it.
	* blockframe.c (inside_entry_file, inside_entry_func):  Do not stop
	backtraces if pc is in the call dummy at the entry point.
	* infcmd.c (run_stack_dummy):  Handle AT_ENTRY_POINT case. Use
	the expected breakpoint pc when setting up the frame for
	set_momentary_breakpoint.
	* symfile.c (entry_point_address):  New function for AT_ENTRY_POINT
	support.
	* valops.c (call_function_by_hand):  Handle AT_ENTRY_POINT case.

If type is defined to another type, copy the type.

48f075eb2a Moved the function hashname from stabsread.c to buildsym.c, since
it's a general-purpose function.
