Use it.
* mips-tdep.c (init_extra_frame_info): Do not check for
mips_in_lenient_prologue if it is a dummy frame.
Use read_memory_nobpt.

to register which is generated by gcc-2.4.
the necessary bits.

which caused problems with assignment of doubles to register variables
on some targets.
* mipsread.c: Remove TM_FILE_OVERRIDE, include tm.h and provide the
missing mips definitions if necessary.

conversion of type held in multiple registers to host format.

Convert to function calls.
* config/mips/tm-mips.h (FIX_CALL_DUMMY): New code for big endian
mips targets.
* mips-tdep.c (mips_print_register): Raw buffer now needs just
MAX_REGISTER_RAW_SIZE bytes.
* mips-tdep.c (mips_print_register): Use REGISTER_CONVERT_TO_TYPE
(if defined) for doubles.
* mips-tdep.c: (mips_extract_return_value, mips_store_return_value):
New functions, take care of REGISTER_CONVERT_TO/FROM_TYPE.
* valops.c (value_assign): Use REGISTER_CONVERT_TO_TYPE if
defined.
* findvar.c (value_from_register): Use REGISTER_CONVERT_TO_TYPE if
defined.
(heuristic_proc_start): use heuristic_fence_post, print better
warnings, but only if not stop_soon_quietly.
(_initialize_mips_tdep): add_set_cmd for heuristic-fence-post.
* breakpoint.c (enable_breakpoint): Don't enable watchpoint if it
went out of scope.
* exec.c (exec_close): Fix storage leak.
* exec.c (exec_file_command): Make sure that bfd doesn't realign the
output sections when patching an executable.
* mips-nat.c (store_inferior_registers): Use REGISTER_PTRACE_ADDR
when writing all registers.
* mips-tdep.c (mips_push_dummy_frame): Save floating point registers
at the right offset in the dummy frame.
* mipsread.c (psymtab_to_symtab_1): Do not complain for stProc,
stStaticProc and stEnd symbols as they are generated by gcc-2.x.
* mipsread.c (mipscoff_new_init): Initialize stabsread and buildsym.
protocol.
* config/idt.mt: New file; uses remote-mips.c
* configure.in (mips-idt-ecoff): New target; uses idt.mt.
* mips-tdep.c (mips_fpu): New variable; controls use of MIPS
floating point coprocessor.
(mips_push_dummy_frame): If not mips_fpu, don't save floating
point registers.
(mips_pop_frame): If not mips_fpu, don't restore floating point
registers.
(_initialize_mips_tdep): New function; let the user reset mips_fpu
variable.
* tm-mips.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): If not
mips_fpu, don't use fp0 as floating point return register.
(FIX_CALL_DUMMY): If not mips_fpu, don't save floating point
registers.
Also added remote-mips.c to .Sanitize file.
* doc/gdbint.texinfo: Update GET_LONGJMP_TARGET, L_SET doc.
* irix4-nat.c, mips-nat.c (JB_ELEMENT_SIZE, get_longjmp_target):
Move from mips-tdep.c and tm-{irix3,mips}.h.
* mips-nat.c: Remove a bunch of code that was ifdef'd out of
native MIPS ports.
* nm-irix3.h, nm-mips.h (GET_LONGJMP_TARGET): Move from tm-irix3.h
and tm-mips.h.
* ultra3-nat.c (register_addr): Move from ultra3-xdep.c.
(fetch_core_registers): Fix bfd_seek arguments.
symbol. #define MIPS_EFI_SYMBOL_NAME instead. Use different
value so that demangler won't be invoked. This greatly speeds up
stepping.
* mips-tdep.c (mips_pop_frame): Rewrite handling of
linked_proc_info so that it properly deallocates the appropriate
item after it is done with it instead of before.
* Don't pass bogus frame pointer to create_new_frame(). Just
leave it as zero so that lower level code will figure out the
correct value.
Fix from Jim Williams.
* stack.c (return_command): Evaluate expression *before* popping
off the stack frames! Fix inspired by Jim Williams.
(up_silently_command, down_silently_command): No sel frame is error.
* defs.h (memcpy, memset): Conditionalize decls on
#ifndef MEM_FNS_DECLARED, since DECstation differs.
(alloca): Break out the STDC and non-STDC alloca cases, to make
it work on old preprocessors as well as "picky ANSI" ones.
* xm-mips.h (memcpy, memset): Declare, and set MEM_FNS_DECLARED.
* mips-tdep.c (heuristic_proc_start): Zero arg produces zero.
* utils.c (fputs_demangled): Rename SLOP since DECstation system
header files define it!
basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
* blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
returns 0, there is no previous frame.
* breakpoint.c (commands_command): If !from_tty, don't call
input_from_terminal_p().
* dbxread.c (record_misc_function): Speed up slightly.
(compare_psymbols): Ditto.
* infcmd.c (do_registers_info): Take a second argument to
determine whether to print float registers. "info registers"
does not do so anymore. "info all-registers" does, now.
* mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
arg and ignore it.
* tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
* inflow.c (initialize_inflow): Set tflags_ours correctly.
