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

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'.

and FRAME_SAVED_L0 when setting saved_regs_addr. SPARC Lynx
stores the registers in a weird order.

symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list):
No longer demangle partial symbols.

of the exec_ops sections, reflect the freeing of the sections
in current_target.

`sizeof dummy', for constructing the call dummy code.
* config/sparc/tm-sparc.h: Add PARAMS declarations to all
function declarations.
* sparc-tdep.c (sparc_pop_frame): Cast result of
read_memory_integer to CORE_ADDR when passing it to PC_ADJUST.
* irix5-nat.c (enable_break): Set breakpoint at the entry point
of the executable, to handle the case where main resides in a
shared library.
* irix5-nat.c (solib_create_inferior_hook): Reset stop_soon_quietly
after shared library symbol reading, to get rid of a warning from
heuristic_proc_start if the startup code has no symbolic debug info.
* breakpoint.h (struct breakpoint): Add new fields language
and input_radix, to enable breakpoint resetting with the
proper language and radix.
* breakpoint.c (set_raw_breakpoint): Initialize them.
(breakpoint_re_set_one): Use them when resetting the breakpoint.
(breakpoint_re_set): Preserve current language and input_radix
across breakpoint_re_set_one calls.

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),

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.

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.

(set_endian_auto): New static function.
(show_endian): Change message based on target_byte_order_auto.

* defs.h (set_endian_from_file): Declare.
define TARGET_BYTE_ORDER as target_byte_order, and declare
target_byte_order as an extern int, and define BITS_BIG_ENDIAN as
a test of TARGET_BYTE_ORDER.

defined:

(set_endian, set_endian_big, set_endian_little): New functions.
(show_endian): New function.
(init_cmd_lists): Initialize endianlist.
(init_main): Add commands ``set endian big'', ``set endian
little'', and ``show endian''.
* a29k-pinsn.c: Rewrite uses of TARGET_BYTE_ORDER and
BITS_BIG_ENDIAN to switch at run time rather than at compile time.
* coffread.c, dwarfread.c, findvar.c, mips-tdep.c: Likewise.
* remote-os9k.c, stabsread.c, valarith.c, valprint.c: Likewise.
