and MMALLOC_CHECK macros, and add comment indicating how host dependent
makefile fragment should modify MMALLOC_CFLAGS to not use mmalloc, or
to use it but to not do heap corruption checking.
* gdbserver/Makefile.in: Ditto.
* utils.c (init_malloc): Replace warning() use with direct call of
fprintf_unfiltered, since current_target has not yet been set and thus
we cannot use warning(). If we try to use mmcheck and it fails,
suggest that this configuration needs NO_MMCHECK or MMCHECK_FORCE
defined. Other small mmalloc related cleanups.

config/sparc/tm-sparclite.h: Initialize tm_print_insn from
TM_PRINT_INSN, which comes from the tm file.
* Makefile.in (INTERNAL_LDFLAGS): Add in flags from configure.
* configure configure.in: Only make sol-thread.o for native.
Also, switch to dlopened libthread_db.so.1.
* sol-thread.c: Switch to using dlopen to get the thread_db
library.
* configure, configure.in: Change test for libthread_db to only
work for configs where build/host/target are the same.
* 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.
* sparclet-rom.c,config/sparc/sparclet.mt,config/sparc/tm-sparclet.h:
New files for target sparclet.
* symfile.c: Add option for 2nd parameter on load command : a load
offset added to the vma of each section.

target.
* configure: Rebuild.
* config/mips/vr4300el.mt (SIM_OBS): Include simulator in
little-endian builds.
* NEWS: Add Alpha Linux as a new native configuration.
* mdebugread.c (parse_symbol): When we find a malloc() symbol with
return type VOID, assume no debugging info is available for that
object file and patch the return value into VOID *. Otherwise,
operations requiring an implicit call to malloc() will fail.
* infrun.c (wait_for_inferior): The criterion to detect entering a
sigtramp handler is now: (a) the current pc is inside a sigtramp
handler, (b) the previous pc is not in a sigtramp handler, and (c)
the current stack pointer is "inner" than the old one. Condition
(c) is new to avoid mistaking a return from a signal handler into
sigtramp as a new sigtramp invocation.
* dcache.c (struct dcache_block): Declare addr as CORE_ADDR. An
int may not be big enough to hold an address.
(dcache_hit): Ditto.
(dcache_peek_byte): Fix indentation.
* configure.in (alpha-*-linux*): Add target.
* configure: Rebuild
* config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro.

SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems
that detect sigtramp code via designated code sequences (as is the
case for Linux/Alpha, for example).

* alpha-tdep.c (alpha_linux_sigtramp_offset): New function.
(alpha_osf_skip_sigtramp_frame): Ditto.
(push_sigtramp_desc): Ditto.
(alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract
sigcontext address from frame.
(alpha_saved_pc_after_call): When in sigtramp, use
alpha_frame_saved_pc() instead of read-register().
(after_prologue): When inside a dynamically generated sigtramp
function, there is no prologue, so return address of first
instruction.
(alpha_in_prologue): Fix typo in comment.
(find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine
whether we're inside a dynamicaly generated sigtramp function. If
so, create and push and appropriate procedure descriptor.
(alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain
the frame past a sigtramp frame (if the current frame is indeed a
sigtramp function).
(init_extra_frame_info): Don't read next frame register off of
stack-pointer when inside a dynamiccaly generated sigtramp.
(alpha_pop_frame): Also unlink and destroy procedure descriptors
created for dynamically generated sigtramp functions.
* alpha-nat.c: When compiling under Linux, include <asm/reg.h> and
<alpha/ptrace.h> instead of <machine/reg.h>
C_STAT symbols.
* h8300-tdep.c (h8300_pop_frame): Reset $sp and $pc correctly.
Flush cached frames just before exiting.
* remote-sim.c (gdbsim_resume): Complain if the program isn't
being run.
* config/h8300/tm-h8300.h (BELIEVE_PCC_PROMOTION): Define.
Fix some bugs exposed by the testsuite. HMSE.
* (procfs_pid_to_str): New routine to print out thread id's in an
intelligible manner.
* sol-thread.c (sol_thread_fetch_registers): Re-order manner in
which supply_register is called to fix bug with writing writing
individual regs.
* config/sparc/tm-sun4sol2.h: Define default for
target_pid_to_str in case host lacks libthread_db.
config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh
config/sparc/tm-sun4sol2.h: Use autoconf to config Solaris thread
and pthread support, since pre-2.5 systems don't come with
libthread_db.so.1.
* procfs.c (info_proc): Use int instead of id_t. Old versions of
Irix don't see to define this.

* inftarg.c (ptrace_him): Now returns pid;
* m3-nat.c (m3_trace_him): Now returns pid;
* infcmd.c (run_command): Minor cleanup.

near where we read the pc to avoid erroneously setting
random_signal for multi-threaded support.
* procfs.c: Add support for Solaris LWPs. Remove def of
LOSING_POLL. Many cleanups... Several workarounds for Solaris
lossage. System call entry and exit are now handled by
dynamically registered handlers.
* (syscallname): Don't barf when handed an unknown syscall
number.
* (info_proc_syscalls): Ditto.
* sol-thread.c: New file. Implements Solaris thread support.
* symfile.c (symbol_file_add): Add call to target_new_objfile to
notify target-dependent code about new symbol tables.
* (clear_symtab_users): Call target_new_objfile to notify it of
the removal of all symbol tables.
* target.c (push_target): Make sure that to_close is non-zero
before calling it.
* target.h (target_new_objfile): Provide default.
* config/alpha/nm-osf2.h: Define LOSING_POLL because this version
of OSF can't hack using poll with /proc.
* config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be
sol-thread-new-objfile.
* config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and
add libthread_db.so.1 to NAT_CLIBS.
* config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and
target_pid_to_str.
before de-referencing it. Prevents deref of NULL pointer if core
file lacks .reg section.
* defs.h: Rename floatformat_{to from}_long_double to
floatformat_{to from}_doublest. Get rid of FLOATFORMAT_{TO
FROM}... macros.
* findvar.c (extract_floating store_floating): Change all refs to
FLOATFORMAT_{FROM TO}... to floatformat_{from to}_doublest.
* utils.c: Change floatformat_{to from}_long_double to
floatformat_{to from}_doublest cuz the new routines will use
whatever size (double or long double) is appropriate.
* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
REGISTER_CONVERT_TO_RAW): Change FLOATFORMAT... macros to
floatformat... routine calls.
user can attach to a previously running program.
* (nindy_fetch_registers nindy_store_registers): Get rid of fp
conversion code. That's all handled in {extract store}_floating
now.

handling zero's, denorms or NaNs.
* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
REGISTER_CONVERT_TO_RAW): Change to using DOUBLST and
FLOATFORMAT_TO/FROM_DOUBLEST macros.
* config/i960/tm-nindy960.h: Undefine
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW, and
REGISTER_CONVERTIBLE. These are no longer necessary now that all
the magic happens in extract/store_floating.
* (dcache_peek dcache_fetch dcache_poke): Make dcache_fetch and
dcache_poke call dcache_xfer_memory directly in order to fix
problems with turning off dcache. dcache_peek is now unnecessary,
so it goes away.
* defs.h: Define new macros HOST_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT
and TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT to specify a pointer
to a struct floatformat. This allows for better handling of
targets whose floating point formats differ from the host by more
than just byte order.
* (floatformat_to_long_double floatformat_from_long_double):
Prototypes for new functions in utils.c.
* (floatformat_to_doublest floatformat_from_doublest): Prototypes
for pointers to floating point conversion functions. The actual
function uses either double or long double if the host supports it.
* findvar.c (floatformat_to_doublest floatformat_from_doublest):
Initialize to point at correct function depending on HAVE_LONG_DOUBLE.
* (extract_floating store_floating): Rewrite. Now, if host fp
format is the same as the target, we just do a copy. Otherwise,
we call floatformat_{to from}_doublest.
* remote-nindy.c (nindy_xfer_inferior_memory): Change param
`write' to `should_write'.
* utils.c (floatformat_to_long_double
floatformat_from_long_double): New routines that implement long
double versions of functions in libiberty/floatformat.c.
* config/i960/tm-i960.h (TARGET_LONG_DOUBLE_FORMAT): Define this for
i960 extended real (80 bit) numbers.
* nindy-share/nindy.c (ninMemGet ninMemPut): Return number of bytes
actually read or written.
* configure: Regenerate.
