6187dfac46 * mdebugread.c (parse_symbol): Don't call ecoff_swap_tir_in or
ecoff_swap_rndx_in directly; use the debug_swap pointer instead.
	(upgrade_type, handle_psymbol_enumerators): Likewise.
	(has_opaque_xref, cross_ref): Likewise.
	(elfmdebug_build_psymtabs): Call swap->read_debug_info to read
	debugging information, rather than doing it here.
	* mipsread.c (mipscoff_symfile_read): Call read_debug_info entry
	point in ecoff_debug_swap backend structure, rather than calling
	ecoff_slurp_symbolic_info directly.

of inftarg.o.
	* config/m68k/tm-dpx2.h (CANNOT_STORE_REGISTER):  Define to inhibit

	symbols, their value is absolute.
	* mdebugread.c (parse_partial_symbols):  Handle Irix 5.2 shared

	start address of the outermost block.
	* mdebugread.c (parse_lines, parse_procedure):  Pass in pst

db2302cb93 * ch-exp.y (decode_integer_value, match_character_literal,
match_bitstring_literal):  Guard tolower calls with isupper,
	tolower on old BSD systems blindly subtracts a constant.
	* dbxread.c (read_ofile_symtab):  Check for __gnu_compiled_* as
	well when determining the producer of the object file.
	* mdebugread.c (has_opaque_xref):  New function to check for
	cross reference to an opaque aggregate.
	* mdebugread.c (parse_symbol, parse_partial_symbols):  Do not
	enter typedefs to opaque aggregates into the symbol tables.
	* mdebugread.c (parse_external):  Remove skip_procedures argument,
	it has always been 1.  Remove code that handled stProc symbols,
	it was never executed and was wrong, as the index of a
	stProc symbol points to the local symbol table and not to the
	auxiliary symbol info. Update caller.
	* mdebugread.c (parse_partial_symbols):  Do not enter external
	stProc symbols into the partial symbol table, they are already
	entered into the minimal symbol table.
	* config/i386/tm-symmetry.h:  Clean up, it is now only used for Dynix.
	Remove all conditionals and definitions for ptx.
	I386_REGNO_TO_SYMMETRY moved to here from symm-tdep.c.
	Fix addresses of floating point registers in REGISTER_U_ADDR.
	STORE_STRUCT_RETURN now handles cc and gcc conventions.
	FRAME_CHAIN, FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC,
	IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET defined to make backtracing through
	signal trampoline code work.
	* config/i386/xm-symmetry.h:  Clean up, it is now only used for Dynix.
	Remove all conditionals and definitions for ptx.
	Remove KDB definitions.
	* symm-nat.c (store_inferior_registers):  Fetch registers before
	storing them to obtain valid floating point control registers.
	Store fpu registers.

	Fix typos.
	* symm-nat.c (child_resume):  Update type of `signal' parameter.
	* symm-tdep.c (I386_REGNO_TO_SYMMETRY):  Moved to tm-symmetry.h.

* alpha-tdep.c:  Gobs of changes (many imported from mips-tdep) to
	improve remote debugging efficiency.  Also fixed problems with
	doing function calls for programs with no entry points.
	* infcmd.c (run_stack_dummy):  Use CALL_DUMMY_ADDRESS instead of
	entry_point_address.
	* inferior.h (PC_IN_CALL_DUMMY):  ditto.
	* mdebugread.c (parse_symbol, parse_procedure, parse_external,
	parse_lines):  Pass section_offsets info to these routines so that
	we can relocate symbol table entries upon readin.
	* (psymtab_to_symtab_1):  Set symtab->primary to tell
	objfile_relocate to do relocations for our symbols.
	* (ecoff_relocate_efi):  New routine to relocate adr field of PDRs
	(which hang off of the symbol table).
	* Use prim_record_minimal_symbols_and_info instead of
	prim_record_minimal_symbols to supply section info to make minimal
	symbol relocations work.
	* minsyms.c (prim_record_minimal_symbols_and_info):  If section is
	-1, try to deduce it from ms_type.
	* objfiles.c (objfile_relocate):  Use ALL_OBJFILE_SYMTABS where
	appropriate.  Handle relocation of MIPS_EFI symbols special. Also,
	add code to relocate objfile->sections data structure.
	* remote.c (get_offsets):  Use new protocol message to acquire
	section offsets from the target.
	* (remote_wait):  Get rid of relocation stuff.  That's all handled
	by objfile_relocate now.
	* config/alpha/alpha-nw.mt (TM_FILE):  Use tm-alphanw.h.
	* config/alpha/tm-alpha.h:  Define CALL_DUMMY_ADDRESS, and
	VM_MIN_ADDRESS.
	* config/alpha/tm-alphanw.h:  DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.

d78d4d1660 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
while (0).  That defeats the whole purpose of using do . . . while (0).
	* mdebugread.c (parse_partial_symbols): Don't use ?: expression as
	list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
	using a ?: expression as an lvalue is not portable.

1037391405 * mdebugread.c (parse_type): Do not complain for types with
an `indexNil' aux index, these are simply undefined types.
	Remove indexNil check from caller of parse_type.
	* mdebugread.c (parse_partial_symbols):  Do not enter
	stGlobal, scCommon symbols into the minimal symbol table, their
	value is the size of the common, not its address.
	Handle scInit, scFini, scPData and scXData sections.
	Use minimal symbol type mst_file_* for stLabel symbols, instead of
	mst_*.
	Enter stProc symbols into the global_psymbols list once, not into
	the static_psymbols_list.
	Get rid of dummy psymtab if it is empty, to allow proper detection
	of stripped executables.
	* mdebugread.c (cross_ref):  Allow cross references to Fortran
	common blocks.

847d977530 * mdebugread.c (new_psymtab): Pass in section_offsets and set
them in the pst.
	* mdebugread.c (handle_psymbol_enumerators):  New function to enter
	the enumerators of an ecoff enum into the partial symbol table.
	* mdebugread.c (parse_partial_symbols):  Call it.
	* symfile.c (reread_symbols):  Initialize objfile->*_psymbols.next.
	* symmisc.c (dump_psymtab):  Fix typo, clean up output of section
	offsets. Cast psymtab->read_symtab to PTR before passing it to
	gdb_print_address.
	* i386-tdep.c (i386_skip_prologue):  Skip over instructions that
	set up the global offset table pointer in pic compiled code.
	* config/mips/tm-mips.h (FIX_CALL_DUMMY):  For big endian targets,
	error() on TYPE_CODE_FLT arguments whose size is greater than 8,
	swap all other TYPE_CODE_FLT arguments as mips_push_arguments
	ensures that floats are promoted to doubles before they are pushed
	on the stack.

0434c1a0c9 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
alpha and irix. The _sigtramp case has to be handled properly
	in the tdep files if we have no ecoff debugging info.
	* alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
	mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
	without PC_REGNUM kludge.
	* mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
	Clean up handling of mips sigtramp frames, improve comments.

various miscellaneous things discovered in the process:
	* printcmd.c, defs.h (print_address_numeric): New function.
	* c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
	breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
	cp-valprint.c (cplus_print_value), infcmd.c (jump_command),

	* breakpoint.c (describe_other_breakpoints),
	symmisc.c (dump_symtab, print_symbol):
	Use filtered not unfiltered I/O.

	just run gdb under a debugger for this (and it had problems with
	printing addresses, how to print b->shadow, etc.).
	* buildsym.c (make_blockvector), core.c (memory_error),
	exec.c (print_section_info), maint.c (print_section_table),
	mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
	symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
	Add comments saying code is broken.  Marked with "FIXME-32x64".
	* dbxread.c (process_one_symbol), partial-stab.h (default),
	remote-vx.c (vx_run_files_info):
	Don't cast int being passed to local_hex_string.
	* symmisc.c (print_symbol): Don't cast long being passed to %lx.
	* symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
	only being a long.
	* symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
	and LOC_LOCAL.
	* printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
	* source.c: Include <sys/types.h> regardless of USG.

a8c498978e * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
compiler generated tag names.
	* mdebugread.c (parse_type):  Handle cross references to qualified
	aggregate types.

config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
	* mdebugread.c (parse_symbol):  Handle enum sh.type produced by
	DEC c89.
	* mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.

ae5c71d6c1 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
to process_one_symbol.
	* symtab.c (find_pc_psymbol):  Search global_psymbols as well to
	avoid caching a bad endaddr in find_pc_partial_function.

504ccfd788 * mdebugread.c: Change the builtin_type_* in this file to
