* 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.
(SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto.
(DYNAMIC_SIGTRAMP_OFFSET): Ditto.
(SIGCONTEXT_ADDR): Ditto.
(FRAME_PAST_SIGTRAMP_FRAME): Ditto.
* config/alpha/alpha-linux.mh: New file.
* config/alpha/alpha-linux.mt: Ditto.
* config/alpha/nm-linux.h: Ditto.
* config/alpha/tm-alphalinux.h: Ditto.
* config/alpha/xm-alphalinux.h: Ditto.
* config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h.
* 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>
* configure: Regenerate.
From: Robert Lipe <robertl@dgii.com>
Add support for SCO OpenServer 5 (a.k.a. 3.2v5*) This
target is an SVR3.2 with COFF, ELF, and shared libes, but
no /proc.
* config/i386/i386sco5.mh: New file.
* config/i386/nm-i386sco5.h: New file.
here from config/i386/xm-i386mach.h, fix name.
* config/i386/nm-sun386.h: Ditto, from config/i386/xm-sun386.h.

* core-regset.c (sys/procfs.h): Only include if HAVE_SYS_PROCFS_H
is defined.
(fetch_core_registers): Turn into stub unless both HAVE_GREGSET_T
and HAVE_FPREGSET_T are defined. These changes allow systems
like linux that are migrating to /proc support to use a single
configuration for both new and old versions.
* config/i386/linux.mt: Note that this is now for both a.out and
ELF systems.
* config/i386/linux.mh (NATDEPFILES): Add solib.o, core-regset.o,
i386v4-nat.o

printf_unfiltered and printf, now that arbitrary limit is gone.
Remove all conditionals and definitions for ptx.
I386_REGNO_TO_SYMMETRY moved to here from symm-tdep.c.
Fix addresses of floating point registers in REGISTER_U_ADDR.
STORE_STRUCT_RETURN now handles cc and gcc conventions.
FRAME_CHAIN, FRAMELESS_FUNCTION_INVOCATION, FRAME_SAVED_PC,
IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET defined to make backtracing through
signal trampoline code work.

Remove all conditionals and definitions for ptx.
Remove KDB definitions.
