Changes to account for name change from cygwin32 to cygwin and
clean up Win32-related ifdefs.

as new threads.
* procfs.c (wait_fd): Note if LWP has exited.
(procfs_wait): use GETPID to get process ID.
NOTE: I didn't commit Kean's changes to configure.host/configure.tgt
yet because they are kind of bogus and I'm punting back to him to let
him figure out what he's trying to do. So configuring for UnixWare
may not work just yet.
To configure.in: make PRINTF_HAS_LONG_LONG check more pedantic; check
that SCANF_HAS_LONG_DOUBLE instead of assuming PRINTF_HAS_LONG_DOUBLE
implies it; document.
* config/i386/cygwin32.mh: because cygwin.dll calls malloc/realloc
to allocate memory for environ space, gdb cannot use memory
checks -- set -DNO_MMCHECK
* ocd.c (ocd_insert_breakpoint, ocd_remove_breakpoint): macro
BDM_BREAKPOINT already has braces around it, remove erroneous ones.
* ser-ocd.c (ocd_write): conditionalize on _WIN32 instead of
__CYGWIN32__
* config/powerpc/tm-ppc-eabi.h: remove BDM_NUM_REGS, BDM_REGMAP
* ppc-bdm.c: move BDM_NUM_REGS, BDM_REGMAP here from tm.h file,
fill in doc fields of bdm_ppc_ops.
(bdm_ppc_fetch_registers): don't ask for invalid registers such
as the MQ or floating point regs not present on ppc 8xx boards
(bdm_ppc_store_registers): don't write those same invalid registers
* config/i386/cygwin32.mh: stop including ocd.o ser-ocd.o
* config/powerpc/ppc-eabi.mt:
* config/powerpc/ppcle-eabi.mt:
* config/powerpc/ppc-sim.mt:
* config/powerpc/ppcle-sim.mt: include ser-ocd.o

(ocd_write): Use dll_do_command rather than do_command.
* config/i386/cygwin32.mh (XDEPFILES): Remove libwigglers.a.
(BDM_DLLNAME, BDM_LIBNAME, BDM_DEFFILE): Don't define.
($(BDM_LIBNAME)): Remove target.
* wigglers.def: Remove.

sub makes, change clean rule to also remove *.a to remove
libwigglers.a, in dependencies: add ppc-bdm.o ocd.o ser-ocd.o and
remove remote-wiggler.o
* configure.in: add DLLTOOL support
* configure: regenerate
* wigglers.def: new file for imports for wigglers.dll
* ser-ocd.c: new file which is layer between ocd.c and either the
wigglers.dll or the target box, only stub so far
* config/powerpc/ppc-eabi.mt: add ppc-bdm.o to TDEPFILES
* config/powerpc/ppc-sim.mt: add ppc-bdm.o to TDEPFILES
* config/i386/cygwin32.mh: add ocd.o ser-ocd.o libwigglers.a
to XDEPFILES, add rules to build libwigglers.a
checking in changes of Stu Grossman <grossman@cygnus.com>:
* remote-wiggler.c: delete
* ocd.c: new, was remote-wiggler.c
always include sys/types.h, include ocd.h, move WIGGLER
commands and many wiggler prototypes to ocd.h, make wiggler_desc
static, stop making local wiggler functions static,
define write_mem_command for wiggler_write_bytes
(wiggler_start_remote): stop hardcoding the target type,
instead set and use a target_type variable.
(wiggler_open): add new target_type and ops args
(wiggler_wait): now no longer takes pid and target_status as args,
stop trying to set target_status struct, remove BGND insn
checks
(read_bdm_registers): renamed to wiggler_read_bdm_registers
(wiggler_read_bdm_registers): numregs arg changed to reglen arg,
remove pktlen check, set reglen instead of numregs
(dump_all_bdm_regs): delete
(wiggler_fetch_registers): delete
(wiggler_prepare_to_store): now just an empty function
(wiggler_store_registers): delete
(wiggler_read_bdm_register): new
(wiggler_write_bdm_registers): new
(wiggler_write_bdm_register): new
(wiggler_write_bytes): use write_mem_command variable instead of
WIGGLER_WRITE_MEM
(get_packet): renamed to wiggler_get_packet, change refs throughout
(put_packet): renamed to wiggler_put_packet, change refs throughout
(wiggler_get_packet): add break to default case of switch,
change length of WIGGLER_GET_VERSION len to 10 from 4 to match
specs
(wiggler_mourn): unpush_target with current_ops, not &wiggler_ops
(flash_xfer_memory): delete
(noop_store_registers): new placeholder replacement for
target_store_registers() which prevents generic_load from trying to
set up the PC.
(bdm_update_flash_command): add store_registers_tmp variable,
make handling of wiggler_ops more generic -- define wiggler_ops
in a target-specific file instead (such as ppc-bdm.c in the case
of the ppc), use current_target to deal with registers again
making this file less target-specific.
(bdm_read_register_command): new
(_initialize_remote_wiggler): stop doing add_target (&wiggler_ops),
comment out add_cmd ("read-register", ...)
* ocd.h: new, contains common wiggler prototypes, command definitions
* ppc-bdm.c: file for ppc-specific OCD code, including target_ops
structure for ppc bdm
(bdm_ppc_open): new
(bdm_ppc_wait): new
(bdm_ppc_fetch_registers): new
(bdm_ppc_store_registers_: new
(_initialize_bdm_ppc): new
* config/powerpc/tm-ppc-eabi.h: add necessary CPU32 BDM defines
whether CRLF_SOURCE_FILES is defined.
(open_source_file): Use OPEN_MODE with open and openp.
(print_source_lines): Use FDOPEN_MODE with fdopen. If
CRLF_SOURCE_FILES is defined, ignore \r characters.
(forward_search_command): Use FDOPEN_MODE with fdopen.
(reverse_search_command): Likewise.
* config/i386/xm-cygwin32.h (CRLF_SOURCE_FILES): Define.
(LSEEK_NOT_LINEAR): Don't define.
* procfs.c: Substantial (but incomplete) changes to support
sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
struct now has substructs like struct flt_ctl instead of
just a fltset_t and has a ctl_fd, status_fd, as_fd, and
map_fd instead of a single fd. Non-sysv4.2mp procfs models
still have the structs and multiple fds, but don't use the
entire struct and the four fds all point to the same thing.
We use PROCFS_USE_READ_WRITE to decide whether to talk to
procfs with reads/writes or use ioctl instead. We use
HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
multiple fds or not. PROC_NAME_FMT is split out into
CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
STATUS_PROC_NAME_FMT.
(procfs_notice_signals): now a necessary wrapper around
(notice_signals): which are the new guts for noticing signals
(open_proc_file): gets a new flag arg used in sysv4.2mp to
determine whether or not to attempt to open the ctl_fd.
(procfs_read_status): new local function, reads procfs status
(procfs_write_pcwstop): new local function, writes a PCWSTOP
(procfs_write_pckill): new local function, writes a PCKILL
(unconditionally_kill_inferior): remove signo since we now
just call procfs_write_pckill().
(procfs_xfer_memory): call lseek with SEEK_SET rather than 0
(proc_iterate_over_mappings): the whole function is ifdefed
on UNIXWARE to keep things readable.
Expanded the syscall_table to include new potential sysv4.2mp
members. Note that all ifdefs of UNIXWARE should be eliminated
if possible or renamed to describe what's being selected for a
bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
IRIX specific code now also checks it's not UNIXWARE.
* config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
* config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
"/debug/%d" as PROC_NAME_FMT used to be
New UnixWare 2.1 configuration
* config/i386/i386v42mp.mt: new
* config/i386/i386v42mp.mh: new
* config/i386/tm-i386v42mp.h: new
* config/i386/nm-i386v42mp.h: new
* configure.tgt: added new entries
* configure.host: added new entries
of 64-bit values on Windows.
* config/i386/xm-windows.h: Leave CC_HAS_LONG_LONG defined,
undefine PRINTF_HAS_LONG_LONG, so that 64-bit values will
be printed without loss of upper bits.
external forms may have different sizes. Don't assume that an
internal_nlist has the same layout as an external_nlist. Create
symbol for n_strx element so to hide specifics of nlist from
partial-stab.h.
* partial-stab.h: Don't reference dbxread symbols directly. Use
CUR_SYMBOL_STRX instead.
* config/i386/xm-windows.h: Define SIGQUIT and SIGTRAP.
* config/v850/tm-v850.h: Define PS_REGNUM and TARGET_V850 for
MSVC builds.
* mswin/gdbwin.c (reg_order): Define register order for V850.
* mswin/gui.cpp (CGuiApp::InitInstance): Define target name for
V850.
* mswin/regdoc.h: Define MAXREGS for V850.
SIGTRAMP_END.
* config/i386/tm-i386os9k.h (SIGTRAMP_START, SIGTRAMP_END):
Define with dummy pc arg.
* config/m68k/tm-nbsd.h: Ditto.
* doc/gdbint.texinfo: Document that SIGTRAMP_START and
SIGTRAMP_END are macros that take an single argument.

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/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.
(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.
