Make Sparc a Multi-Arch target.  Discard PARAMS macro (require ANSI).
	* sparc-tdep.c: include arch-utils.h.
	(SPARC_HAS_FPU, FP_REGISTER_BYTES, FP_MAX_REG NUM, SPARC_INTREG_SIZE,
	DUMMY_REG_SAVE_OFFSET): provide multi-arch-compatible definitions.
	(GDB_TARGET_IS_SPARC64): make into a runtime test.
	(struct frame_extra_info): Define, use instead of the macro.
	(Many places): Use alloca instead of statically allocated buffers
	that depend on a multi-arch variable such as MAX_REGISTER_RAW_SIZE.
	(sparc_extract_struct_value_address): Accept a pointer arg instead
	of an array sized by REGISTER_BYTES.
	(examine_prologue): Accept a pointer to an array of CORE_ADDR,
	instead of the defunct struct frame_saved_regs.  Recognize new
	Sparc64 store instructions as part of the prologue.  Ignore the
	destination of a frame store when parsing the prologue (so long
	as it's on the stack).
	(sparc_push_dummy_frame): Fix incorrect buffer offset for PSTATE.
	(sparc_frame_find_saved_regs): Accept a ptr to an array of CORE_ADDR
	instead of the defunct struct frame_saved_regs.
	(supply_gregset): Discard unnecessary 'zerobuf': just send NULL to
	supply_register.  Provide 4-byte offset to compensate for diff
	between size of the prgreg_t elements on a 64-bit host and size
	of the registers for a 32-bit target.  Fill all inaccessible regs
	with zero so they won't keep being requested again and again.
	(fill_gregset): Handle 32/64 size difference between registers
	and prgreg_t.  Handle as many new 64-bit regs as possible.
	(supply_fpregset, fill_fpregset): Attempt to handle 64-bit world.
	(sparc_push_arguments): Rename to sparc32_push_arguments.
	Copy arguments into registers as well as onto stack, so that the
	CALL_DUMMY (code pushed onto the target stack) is not required.
	(sparc_extract_return_value): Rename to sparc32_extract_return_value.
	(sparc_store_return_value): Use memset instead of bzero.
	Use write_register_gen instead of write_register_bytes.
	(sparclet_store_return_value): New function.
	(_initialize_sparc_tdep): Call register_gdbarch_init to activate
	the gdbarch multi-architecture system.
	(sp64_push_arguments): Rename to sparc64_push_arguments.
	Extend to store arguments in general registers as well as on stack.
	(sparc64_extract_return_value): Rename to sp64_extract_return_value.
	Use as a private function, to be called by the new external function
	sparc64_extract_return_value.
	(sparclet_extract_return_value): New function.
	(sparc32_stack_align, sparc64_stack_align, sparc32_register_name,
	sparc64_register_name, sparc_print_extra_frame_info,
	sparclite_register_name, sparclet_register_name,

	sparc_y_regnum, sparc_reg_struct_has_addr, sparc_intreg_size,
	sparc_return_value_on_stack): New functions supporting multi-arch.
	(sparc_gdbarch_init): New function; initialize multi-arch.
	(struct gdbarch_tdep): Define, use for private multi-arch data.
	* config/sparc/tm-sparc.h: Move definitions around, enclose with
	#ifdef GDB_MULTI_ARCH tests, provide some multi-arch alternate
	definitions.  Add enums for register names, to help debugging gdb.
	This header file must work for non-multi-arch and for multi-arch.
	* config/sparc/tm-sp64.h: Add GDB_MULTI_ARCH configuration.  Also add
	AT_ENTRY_POINT definitions for CALL_DUMMY, for non-multi-arch case.
	Define GDB_MULTI_ARCH.
	* config/sparc/tm-sparclet.h: Add GDB_MULTI_ARCH configuration.
	Do not define GDB_MULTI_ARCH (bfd does not correctly identify target).
	* config/sparc/tm-sparclite.h: Ditto.
	* config/sparc/tm-sun4sol2.h: Define GDB_MULTI_ARCH.
	* sparclet-rom.c (sparclet_regnames): Initialize explicitly, to
	avoid using deprecated REGISTER_NAMES macro.
	* Makefile.in: Let sparc-tdep.c depend on arch-utils.h.

012be3cec3 * configure,configure.in: Add target sparclet.
* monitor.h,monitor.c:
    Added monitor flags MO_NO_ECHO_ON_SETMEM (don't expect echo on
    setmem command), MO_RUN_FIRST_TIME (if command to start process
    running on target is different from one to continue execution),
    MO_HEX_PREFIX (if addresses from monitor have a "0x" prefix).
    * monitor.c,parse.c,sparc-tdep.c:
    Don't require strings in the registers array.  This is to allow
    NULLs to be place holders in the tm-*.h file so that only minor
    changes are needed when a new processor is introduced (eg, one
    without floating point).
    * sparc-tdep.c: Conditionally remove dependancies on floating point.

16726dd15b The point of these changes is to avoid reading the frame pointer
and stack pointer during stepping, to speed things up.
	A.  Changes to not select a frame until we need a selected frame:
	    * blockframe.c (flush_cached_frames): Call select_frame (NULL, -1).
	    * infrun.c (wait_for_inferior): Move call to select_frame back to
	    normal_stop.  This reverts a change of 13 Apr 94 (it says Jeff
	    Law, but the change was my idea); the only reason for that change
	    was so we could save and restore the selected frame in
	    wait_for_inferior, and now that flush_cached frames clears the
	    selected frame, that should work OK now.
	B.  Changes to not create a current_frame until we need one:
	    * blockframe.c (get_current_frame): If current_frame is NULL, try
	    to create an innermost frame.
	    * sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy),
	    infrun.c (wait_for_inferior), thread.c (thread_switch),
	    convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame),

	    (POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't
	    call create_new_frame.
	    * corelow.c (core_open), altos-xdep.c (core_file_command),
	    arm-xdep.c (core_file_command), gould-xdep.c (core_file_command),
	    m3-nat.c (select_thread), sun386-nat.c (core_file_command),
	    umax-xdep.c (core_file_command): Don't call create_new_frame; do
	    call flush_cached_frames.
	    * blockframe.c (reinit_frame_cache): Don't call create_new_frame
	    or select_frame.
	C.  Changes to get rid of stop_frame_address and instead only
	fetch the frame pointer when we need it.
	    * breakpoint.c (bpstat_stop_status): Remove argument
	    frame_address; use FRAME_FP (get_current_frame ()).
	    * infrun.c (wait_for_inferior): Don't pass frame pointer to
	    bpstat_stop_status.
	    * infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame
	    ()) instead of stop_frame_address.
	    * infrun.c (save_inferior_status, restore_inferior_status),
	    inferior.h (struct inferior_status): Don't save and restore
	    stop_frame_address.
	    * inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c
	    (select_thread): Remove stop_frame_address and uses thereof.
	D.  Same thing for the stack pointer.
	    * infrun.c (wait_for_inferior): Remove stop_sp and replace
	    uses thereof with read_sp ().
	E.  Change to eliminate one nasty little spot where we were
	wanting to know the frame pointer from before the current step
	(idea from GDB 3.5, which saved my ass, because my other ideas of
	how to fix it were very baroque).
	    * infrun.c: Remove prev_frame_address.
	    * infrun.c (wait_for_inferior, step_over_function): Use
	    step_frame_address instead of prev_frame_address.
	F.  Same basic idea for the stack pointer.
	    * inferior.h, infcmd.c: New variable step_sp.
	    * infcmd.c (step_1, until_next_command): Set it.
	    * infrun.c: Remove prev_sp and replace uses by step_sp.
	    * infrun.c (wait_for_inferior): If we get out of the step
	    range, then set step_sp to the current stack pointer before we
	    start going again.

Jim Kingdon
94d4b71373 * Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE.  This is faster
	and means that these filenames no longer need be unique across all
	the config/* directories.
	* configure.in: Put the config/*/ into TM_FILE, etc.

	* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
	and trapv exceptions.

	* target.h (struct section_table), objfiles.h (struct obj_section):
	Change name of field sec_ptr to the_bfd_section.  More mnemonic
	and avoids the (sort of, for the ptx compiler) name clash with
	the name of the typedef.
	* exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
	solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.

	* utils.c: Include readline.h.
	* Makefile.in (utils.o): Add dependency.

	* remote.c (getpkt): Add support for run-length encoding.

	* sparc-tdep.c: Remove now-obsolete ieee-float.h stuff
	* findvar.c: Update comment regarding ieee-float.h.

Stu Grossman
8bf94f44bc * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
	tm-sparc.h so they can be overridden if necessary.
1994-01-22 08:42:14 +00:00
Peter Schauer
f1de67d323 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
in case execution was stopped in the called function.
	* stack.c (print_frame_info, frame_info):  If backtracing through
	a call dummy, handle the starting source line number on a line
	boundary like backtracing through sigtramp.
	* sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
	for call dummy frame right.  Remove old test for dummy frame,
	it has been unused at least since gdb-3.5.
	* sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
	of the dummy frame.

34df79fc9d * findvar.c, defs.h
({extract,store}_{signed_integer,unsigned_integer,address}):
	New routines to replace SWAP_TARGET_AND_HOST.
	All over: All uses of SWAP_TARGET_AND_HOST on integers replaced.
1993-07-10 01:35:53 +00:00
Jim Kingdon
dd99f8e4b2 * sparc-tdep.c (sparc_push_dummy_frame): Skip all the do_save_insn
stuff, just write the sp and fp.
	(sparc_pop_frame): Skip the do_restore_insn; we already restore
	the sp with the other out registers.
1993-07-09 03:53:46 +00:00
David Edelsohn
6ac063909f (sparc_frame_chain): Handle sizeof (CORE_ADDR) != sizeof (REGISTER_TYPE).

	Don't use obj_section hack.
	* xcoffexec (vmap_symtab): Relocate obj_sections.
	* printcmd.c (containing_function_bounds): Use find_pc_section.

b38f304c4f * putenv.c: index -> strchr.
* regex.c:  Always rename bcopy to memcpy, etc.
FIXME:  Eventually do the renames rather than use #define's.

Fix bcopy->memcpy.
* sparc-xdep.c:  Move deferred_stores to target dependent.

	utils.c, valarith.c, valops.c, valprint.c, values.c:
	Replace bcopy() use with memcpy(), which is more standard and can
	take advantage of gcc's builtin functions for increased performance.
	* breakpoint.c, buildsym.c, coffread.c, dbxread.c, i386-tdep.c,
	ieee-float.c, infcmd.c, sparc-tdep.c, stack.c, symtab.c, symtab.h,

John Gilmore
8f86a4e465 * remote.c (getpkt): Error if input exceeds buffer size.
(_initialize_remote):  `set remotedebug' enables packet trace.

* dbxread.c (process_one_symbol:N_FUN):  GCC now produces relative
N_SLINE's, etc, just like Sun cc on Solaris2.

* am29k-tdep.c (read_register_stack, write_register_stack):
Change RSTACK_HIGH_ADDR to rstack_high_address, a user-settable
variable.  Add `set' and `show' commands for it.
* doc/gdb.texinfo:  Document it.

* eval.c:  Avoid residue-by-zero when evaluating without side effects.
(Bug and fix found by Pierre Willard.)

* sparc-tdep.c:  Clean up slightly for Solaris2.

f9e3b3ccc2 * target.c (nomemory): Now that higher levels examine errno, give EIO.
* tm-sparc.h:  Don't #include <sun4/reg.h>.
* sparc-tdep.c (sparc_frame_chain, frame_saved_pc):  Remove
dependency on <sun4/reg.h>.  Start to handle cross-byte-order.
* language.h:  Avoid forward enum declaration.
* configure.in, tm-sun4os5.h, xm-sun4os5.h, config/sun4os5.mh,
config/sun4os5.mt:  New host and target.
* defs.h (errno): #include <errno.h> rather than assuming int.
From Pierre Willard.
1992-03-29 23:14:34 +00:00
John Gilmore
5e5215eba7 * mcheck.c: Avoid warning about undeclared abort fn.
* tm-sparc.h (PC_ADJUST):  Avoid calling error() from this;
it causes recursive calls to error() when used in cleanups.
To do so requires that we make it a function, so we do.
* sparc-tdep.c (sparc_pc_adjust):  New implem of PC_ADJUST.
* utils.c (do_cleanups):  Remove the current cleanup from the
chain *before* calling it, in case error() is called from it.
The result won't be pretty, but won't be an infinite loop either.

John Gilmore
5259796be2 * blockframe.c (frameless_look_for_prologue): Speed up by
calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
        * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
        Define two variants, one faster.
        * sparc-tdep.c (sparc_frame_chain):  Use target_read_memory
        and return zero, rather than giving an error.
        (setup_arbitrary_frame):  Initialize the PC in the new frame.
        (skip_prologue):  Add a second arg saying whether we're just
        checking for a frameless function or not.
