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.
