Stu Grossman aa220473ba * Add native support for long double data type.
* c-exp.y (%union):  Change dval to typed_val_float.  Use DOUBLEST
	to store actual data.  Change types of INT and FLOAT tokens to
	typed_val_int and typed_val_float respectively.  Create new token
	DOUBLE_KEYWORD to specify the string `double'.  Make production
	for FLOAT use type determined by parse_number.  Add production for
	"long double" data type.
	* (parse_number):  Use sscanf to parse numbers as float, double or
	long double depending upon the type of typed_val_float.dval.  Also
	allow user to specify `f' or `l' suffix to explicitly specify
	float or long double constants.  Change typed_val to
	typed_val_int.
	* (yylex):  Change typed_val to typed_val_int.  Also, scan for
	"double" keyword.
	* coffread.c (decode_base_type):  Add support for T_LNGDBL basic
	type.
	* configure, configure.in:  Add check for long double support in
	the host compiler.
	* defs.h:  Define DOUBLEST appropriatly depending on whether
	HAVE_LONG_DOUBLE (from autoconf) is defined.  Also, fix prototypes
	for functions that handle this type.
	* expression.h (union exp_element):  doubleconst is now type
	DOUBLEST.
	* m2-exp.y f-exp.y (%union):  dval becomes type DOUBLEST.
	* findvar.c (extract_floating):  Make return value be DOUBLEST.
	Also, add support for numbers with size of long double.
	* (store_floating):  Arg `val' is now type DOUBLEST.  Handle all
	floating types.
	* parser-defs.h parse.c (write_exp_elt_dblcst):  Arg expelt is now
	DOUBLEST.
	* valarith.c (value_binop):  Change temp variables v1, v2 and v to
	type DOUBLEST.  Coerce type of result to long double if either op
	was of that type.
	* valops.c (value_arg_coerce):  If argument type is bigger than
	double, coerce to long double.
	* (call_function_by_hand):  If REG_STRUCT_HAS_ADDR is defined, and
	arg type is float and > 8 bytes, then use pointer-to-object
	calling conventions.
	* valprint.c (print_floating):  Arg doub is now type DOUBLEST.
	Use appropriate format and precision to print out floating point
	values.
	* value.h:  Fixup prototypes for value_as_double,
	value_from_double, and unpack_double to use DOUBLEST.
	* values.c (record_latest_value):  Remove check for invalid
	floats.  Allow history to store them so that people may examine
	them in hex if they want.
	* (value_as_double unpack_double):  Change return value to DOUBLEST.
	* (value_from_double):  Arg `num' is now DOUBLEST.
	* (using_struct_return):  Use RETURN_VALUE_ON_STACK macro (target
	specific) to expect certain types to always be returned on the stack.

Jim Kingdon 79971d11cc * valops.c (value_assign): Call reinit_frame_cache when assigning
to a register.
1993-10-26 15:49:39 +00:00
Jim Kingdon 443abae18c * findvar.c, value.h (symbol_read_needs_frame): New function.
* c-exp.y, m2-exp.y: Call it instead of having our own switch on
	the symbol's class.
	* valops.c (value_of_variable): Use symbol_read_needs_frame to
	decide whether we care about finding a frame.
1993-10-08 20:33:22 +00:00
Peter Schauer cef4c2e7a5 Changes to support alpha OSF/1 in native mode.
* alpha-nat.c, alpha-tdep.c, config/alpha/alpha-osf1.mt,
	  config/alpha/nm-alpha.h, config/alpha/tm-alpha.h, osfsolib.c:
	New files.
	* Makefile.in:  Add new files and dependencies.
	* configure.in:  Add alpha target.
	* config/alpha/alpha-osf1.mh (NATDEPFILES):  Add osfsolib.o
	* config/alpha/alpha-osf1.mh (MH_CFLAGS):  Remove, we can handle
	shared libraries now.
	* config/alpha/xm-alpha.h:  Cleanup, get MAKEVA_* defines right.

	* defs.h (CORE_ADDR):  Make its type overridable via CORE_ADDR_TYPE,
	provide `unsigned int' default.
	* 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.

	domain is an undefined cross reference.
	* valops.c (call_function_by_hand):  Set real_pc to correct
1993-09-17 11:46:50 +00:00
Jim Kingdon 860a1754fd * infcmd.c, inferior.h (run_stack_dummy): If we stop somewhere

	Let caller print the error message.  Remove name argument.
	* valops.c (call_function_by_hand): Deal with changes to calling
	sequence of run_stack_dummy.  Discard restore_inferior_status cleanup
	if run_stack_dummy returns 1.

1993-07-08 03:32:00 +00:00
Stu Grossman b5728692b4 * Fix two bugs found by deja-gnu. One is the incorrect reporting
of the PC being in a stack dummy when looking at a core file
	without symbols.  The other is the incorrect passing of char
	arguments during expression evaluation (ie: p foo('a','b') would
	mess up the passing of it's args because it wasn't coercing the
	char's to ints).
	* hppah-tdep.c:  Rename global functions to have consistent hppa_
	prefix.  Make more functions static.  Drop hp_ prefix from static
	functions.  (hppa_push_arguments):  Call value_arg_coerce to cast
	char to int args if necessary.  (hppa_fix_call_dummy):  Create
	this routine from FIX_CALL_DUMMY macro in tm-hppa.h.

	valid (ie: != 0) before doing comparison against PC.
	* valops.c (call_function_by_hand):  Adjust call to FIX_CALL_DUMMY
	to reflect new arguments.
	* config/pa/tm-hppa.h (POP_FRAME, PUSH_ARGUMENTS):  Use new hppa_
	prefix for func	name.  (FIX_CALL_DUMMY):  Move code into
	hppah-tdep.c.

	* testsuite/gdb.t16/gdbme.c, testsuite/gdb.t17/gdbme.c:  Add calls
	to malloc() so that we can test GDB eval of dynamically created
	arrays (like char strings in `print "foo"').
1993-04-23 18:01:02 +00:00

	cleanups, use new code from Utah.
	* (store_inferior_registers):  Update to new code from Utah.
	* (initialize_kernel_u_addr):  Re-enable decl of struct user u.
	* (fetch_register):  Clear out priv level when reading PCs.
	* hppah-tdep.c:  Get rid of gobs of KERNELDEBUG stuff.
	* Remove decl of errno, #include wait.h and target.h.
	* (frame_saved_pc):  Check `flags' pseudo-register to see if we
	were inside of a kernel call.  If so, then PC is in a different
	register.  Also, mask out bottom two bits of all PCs so as not to
	confuse higher level code.
	* (push_dummy_frame):  Create from #define in tm-hppa.h.
	* (find_dummy_frame_regs):  Update from Utah.

	* i860-tdep.c:  Remove decl of attach_flag.
	* infrun.c (wait_for_inferior):  Add new macro
	INSTRUCTION_NULLIFIED, which can tell if the instruction pointed

	so as to avoid confusing the user.
	* (just before step_over_function:):  Use stop_func_start, not
	stop_pc when checking for the existance of line number info.
	stop_func_start will reflect the proper address of the target
	routine, not of the stub that we may be traversing to get there.
	* tm-hppa.h:  define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE
	to deal with the stubs that PA compilers sometimes stick between
	callers and callees.  Also, define FLAGS_REGNUM for access to the
	`flags' pseudo-reg.
	* (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW):  Use
	memcpy, not bcopy.

	* Define struct unwind_table_entry.
	* valops.c (call_function_by_hand):  Add another arg to
	FIX_CALL_DUMMY (under #ifdef GDB_TARGET_IS_HPPA).  Why is this
	necessary?
1992-12-22 03:18:46 +00:00
Fred Fish bac89d6ca8 * c-exp.y (yylex): Add tempbuf, tempbufindex, and tempbufsize,
which together maintain a dynamically expandable static buffer

	form (other future uses possible).  Fix parsing of C style strings
	to do the normal C style input conversions of escaped character
	sequences.
	* valops.c (value_string):  Remove translation of escaped
	character sequences, now done in C expression parser.
1992-11-24 03:02:10 +00:00

	ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,
