* 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.

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).

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>

for the H8/300H. Handle H8/300H prolouge code sequences.
Avoiding major breakage on the H8/300H, and on the eval board. Jeez, did
anyone even try to debug H8/300H code with gdb in the past?!?
