Jim Kingdon
a81ce07da8 * xcoffread.c (process_xcoff_symbol): Use new variables 
func_symbol_type and var_symbol_type as type of functions and
	variables which don't have any stabs associated with them.
	Reindent most of function.
	(_initialize_xcoffread): Initialize *_symbol_type.

	* xcoffread.c (read_xcoff_symtab): Reindent most of function.
	Put C_HIDEXT symbols in the minimal symbols, rather than ignoring
	them (this part commented out as I didn't quite get it to work).
	(cs_to_section, find_targ_sec): New functions, to support above code.
	* xcoffread.c (RECORD_MINIMAL_SYMBOL): Only skip '.' if it is
	actually present.

07aa9fdc6b * eval.c (evaluate_subexp): Make fnptr a LONGEST instead 
of using longest_to_int.

	* infcmd.c (run_stack_dummy):  Reinstate set_current_frame call,
	mips and alpha targets need the real breakpoint pc for
	creating the breakpoint frame.

	* stack.c (return_command):  Cast return value to the return
	type of the function from which we return.
	* values.c (set_return_value):  Pass VALUE_CONTENTS unmodified
	to STORE_RETURN_VALUE.

	* symtab.c (lookup_symbol):  Remove search for `static mangled
	symbols', the search for `static symbols' already looks for
	mangled and demangled symbols via lookup_block_symbol.

	* valarith.c (value_binop):  Use ANSI C arithmetic conversions
	when performing integral evaluations, implement BINOP_EQUAL and
	BINOP_LESS.
	(value_equal, value_less):  Use value_binop to perform the
	comparison if both operands have TYPE_CODE_INT.

	* rs6000-tdep.c (pop_frame):  Make sure all registers are valid,
	as they are written back later. Handle sp restore for frameless
	functions. Use fdata.nosavedpc instead of fdata.frameless to
	determine if the pc has been saved.
	(function_frame_info):  Handle `mr r31,r1', which is generated by
	gcc-2.6, as a synonym for `oril r31,r1,0'.
	(skip_trampoline_code):  Handle shared library trampolines.
	* xcoffread.c (read_xcoff_symtabs):  Record XMC_GL symbols with
	their real name. Enables setting of breakpoints in shared libraries
	before the executable is run.

f69ecb9c9a * xcoffread.c (read_xcoff_symtab): Fix obsolete comment about 
mst_solib_trampoline.

	* f-valprint.c (f_val_print): Change cast of valaddr from
	CORE_ADDR * to char **, since that is how it is used.

	* dbxread.c (read_dbx_dynamic_symtab): Save copy of symbol names
	using obsavestring, and pass that to prim_record_minimal_symbol.
	Having the objfile point to bfd_asymbol_name directly doesn't work
	if we save and restore a mapped symbol file.

7f4c859520 * objfiles.c (allocate_objfile): Add the newly-created objfile to 
the end of the list of objfiles, instead of at the beginning.

	* xcoffread.c (allocate_include_entry): New function, abstracted
	from code in record_include_begin.
	(record_include_begin, record_include_end): Call it.

	* blockframe.c (reinit_frame_cache): Test inferior_pid instead of
	target_has_stack to decide whether to create a real stack frame
	for the cache.

	* coffread.c (process_coff_symbol) [CXUX_TARGET]: Ignore vendor
	section.
	* config/m88k/tm-cxux.h (CXUX_TARGET): Define.

	* h8300-tdep.c: Include "dis-asm.h" instead of <dis-asm.h>.

70e375c356 Mon Apr 11 19:21:27 1994 Stu Grossman (grossman at cygnus.com) 
* xcoffread.c (read_xcoff_symtab):  Ignore symbols of class C_EXT,
	smtyp XTY_LD, sclass XMC_DS (external data segment label).  They
	often have the same names as debug symbols for functions, and
	confuse lookup_symbol().

199b2450f6 Change the stream argument to _filtered to GDB_FILE *. 
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.
