* gdbarch.c, gdbarch.h: Regenerated.
* valprint.c (IEEE_FLOAT): Provide a default #definition for this.
(print_floating): Use IEEE_FLOAT as if it were an expression; use
the code specific to IEEE-format numbers whenever the value of
IEEE_FLOAT is non-zero.

IEEE_FLOAT, make sure they give it the value (1).
and P_LINK_W.
(P_PEA_FP, P_MOVL_SP_FP): New macros.
(P_MOVL, P_LEAL, P_MOVML): Macros renamed from P_MOV_L, P_LEA_L and
P_MOVM_L.
(altos_skip_prologue, isi_skip_prologue): Use P_* macros, not octal
constants.
(delta68_in_sigtramp): New function.
(delta68_frame_args_address, delta68_frame_saved_pc): Ditto.
(m68k_skip_prologue): Use P_* macros, not hex constants.

instructions, but accept them in any order; use P_* macros, not octal
or hex constants; recognize also `fmovemx to (fp + displacement)' and
`moveml to (fp + displacement)'.
* m68/tm-delta68.h (IN_SIGTRAMP): New macro.
(FRAME_SAVED_PC, FRAME_ARGS_ADDRESS): Ditto.

both m68k-tdep.c and m68klinux-nat.c contain definitions
for supply_gregset and supply_fpregset. The definitions
in m68k-tdep.c are valid is USE_PROC_FS is defined. Otherwise,
the definitions in m68klinux-nat.c will be used. This is a
bit of a hack. The supply_* routines do not belong in
*_tdep.c files. But, there are several lynx ports that currently
depend on these definitions.

(puts_debug): Change 'carriage_return' local variable to return_p
to avoid name clash.

Replace ANSI string concatenation with K&R compatible simple string.
* m68k/tm-delta68.h (EXTRACT_RETURN_VALUE): Type argument for
`REGISTER_CONVERT_TO_VIRTUAL is `TYPE', not
`REGISTER_VIRTUAL_TYPE (FP0_REGNUM)';
(STORE_RETURN_VALUE): Ditto, and offset for `write_register_bytes'
is `REGISTER_BYTE (FP0_REGNUM)', not `FP0_REGNUM'.
(FRAME_NUM_ARGS): New macro.
* m68k/tm-news.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Ditto.
* delta68-nat.c (clear_insn_cache): New function, forgotten in previous
patch.
* m68k/tm-delta68.h (CPLUS_MARKER): Macro deleted.
(EXTRACT_STRUCT_VALUE_ADDRESS): Macro defined.
(EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Macros modified
because floating-point values return via %fp0.
(CLEAR_INSN_CACHE): New macro.
* m68k/tm-m68k.h (REGISTER_CONVERT_TO_VIRTUAL): Macro fixed
to use DOUBLEST.

FRAME_SAVED_PC.
* (frame_saved_pc): Change name to hppa_frame_saved_pc.
* (hppa_pop_frame): Don't use a pid of 0 with target_write_pc.
Use write_pc instead, which uses the correct pid.
* (target_read_pc target_write_pc): Use read/write_register_pid
instead of read/write_register to preserve the pid passed in.
* inftarg.c (child_can_run): Add flag child_suppress_run to allow
hpux-threads.c to override this as a runnable target.
* config/pa/nm-hppah.h: Define target_new_objfile and
target_pid_to_str.

SIGTRAMP_END are macros that take an single argument.
mswin/libwingdb.a and remote-wiggler.o.
* breakpoint.c (breakpoint_here_p): Clean up bp enabled test.
* (breakpoint_inserted_here_p): New func, just like
breakpoint_here_p, except it's honest. Honestly.

output modes (set remotelogbase {hex|octal|ascii}. Also log
breaks, timeouts, errors, and eofs.

function so that we can log breaks. Don't export serial_logfile
or serial_logfp.

Just call serial_log_comand, and let serial.c sort it out.
* valops.c (value_of_variable): Don't attempt to establish frames
for static and global variables. This makes things work a bit
better if the stack or frame pointer is trashed.

for details about these changes. I was going to include the complete
entry in the checkin message but it was apparently so large it caused
cvs to dump core.
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/sun4os4.mh (MMALLOC_CFLAGS): Define MMCHECK_FORCE to 1.
* config/alpha/alpha-osf2.mh (MMALLOC_CFLAGS): Set to -DNO_MMCHECK.
* config/sparc/xm-sun4os4.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/i386/xm-i386v4.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/i386/xm-linux.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/m68k/xm-hp300hpux.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/m68k/xm-m68kv4.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT);
* config/m68k/xm-sun3os4.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/pa/xm-hppah.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
* config/sparc/xm-sun4sol2.h (MMAP_BASE_ADDRESS, MMAP_INCREMENT):
Remove obsolete defines.

* config/i386/i386m3.mh (MMALLOC_DISABLE):
* config/i386/i386gnu.mh (MMALLOC_DISABLE):
Use MMALLOC_CFLAGS instead.
* 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.

* config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to
xm-alphaosf.h.
* config/alpha/alpha-osf2.mh: Ditto.
* blockframe.c (find_pc_partial_function): Pass PC to
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).
* config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END
to ignore new PC argument.
* config/m68k/tm-hp300bsd.h: Ditto.
* config/vax/tm-vax.h: Ditto.
* 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>
* config.in: Regenerate with autoheader.
* configure: Regenerate with autoconf.
* inflow.c (_initialize_inflow): Only try to use _SC_JOB_CONTROL
if it is actually defined.
(gdb_setpgid): Use HAVE_SETPGID.
* ch-exp.c: Change include of <string.h> to "gdb_string.h".
* c-exp.y: Ditto.
* f-exp.y: Ditto.
* m2-exp.y: Ditto.
* c-exp.y: Include <ctype.h>.
* serial.c: Ditto.
* config/m68k/nm-news.h: Add typedef for pid_t which is
apparently missing from <sys/types.h>. Enclose entire
file in NM_NEWS_H ifndef and define when included.
* config/mips/nm-news-mips.h: Ditto.
* config/m68k/tm-m68k.h (REGISTER_CONVERT_TO_VIRTUAL,
REGISTER_CONVERT_TO_RAW): Change name of temporary variable.
