1474 remote_debug echoing. That's handled in readchar as well.
1475 (e7000_parse_device): Remove serial_flag arg. It's not
1477 (e7000_open): Split into two pieces. Second part is
1478 e7000_start_remote, and is error protected. Now, when we connect
1479 to the target, we setup the initial frame and registers so that
1480 the user gets an immediate indication of where the target is.
1481 (gch): Remove debug output. That's handled by readchar.
1482 (e7000_read_inferior_memory): Handle errors better.
1483 (_initialize_remote_e7000): Get rid of `<xxx>' things from
1484 command names. They show up when doing completion and confuse
1486 * ser-e7kpc.c: Get rid of the DLL's since we can access the device
1487 directly from Win32s and Win95. Get rid of debugify crud.
1488 * serial.c: Remove debugify cruft.
1489 * (serial_logchar serial_log_command serial_write serial_readchar
1490 serial_send_break serial_close): Merge common functionality into
1491 serial_logchar. Clean up rest of routines.
1492 * sparclet-rom.c: Disembowel. Leave only download routine.
1493 Download routine now switches to remote target automatically.
1494 * top.c (disconnect): Only define if SIGHUP is defined. Cleans
1495 up MSVC/Win32 problem.
1496 * utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout
1498 * config/sh/tm-sh.h: Define TARGET_SH for WinGDB.

1503 * remote-sim.c (gdbsim_open): Only pass -E to sim_open if
1504 TARGET_BYTE ORDER_SELECTABLE.
1506 Fri Apr 18 16:52:41 1997 Andrew Cagney <cagney@b1.cygnus.com>

1513 sim_wait where gdb is in a position to handle a long running
1515 (gdbsim_cntrl_c): New function. Wrap the sim_resume call in a
1517 (gdb_os_poll_quit): New function. Check for a quit pending on the
1520 start-sanitize-gdbtk
1521 Wed Apr 16 12:33:06 1997 Andrew Cagney <cagney@b1.cygnus.com>
1523 * Makefile.in (install-only): Make list of gdbtcl files to install
1524 explicit - was picking up files such as ChangeLog etc.
1525 (install-only): Don't blindly create the directory.
1528 Thu Apr 17 14:30:04 1997 Per Bothner <bothner@deneb.cygnus.com>

1551 * remote.c (get_offsets): Don't use scanf for interpreting
1552 response to qOffsets.
1554 Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
1556 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1557 (INSTALL_XFORM1): Remove.
1558 (install-only): Use $(program_transform_name) directly, rather
1559 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).
1560 (uninstall): Transform name.
1562 Mon Apr 14 17:06:27 1997 Mark Alexander <marka@cygnus.com>
1564 * remote-mips.c (mips_load): Ensure that PC gets updated
1565 after a load on LSI target.
1567 Mon Apr 14 15:54:51 1997 Geoffrey Noer <noer@pizza.cygnus.com>

1576 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1578 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1579 since gcc automatically includes it
1581 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1583 * procfs.c: Substantial (but incomplete) changes to support
1584 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1585 struct now has substructs like struct flt_ctl instead of
1586 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1587 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1588 still have the structs and multiple fds, but don't use the
1589 entire struct and the four fds all point to the same thing.
1590 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1591 procfs with reads/writes or use ioctl instead. We use
1592 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1593 multiple fds or not. PROC_NAME_FMT is split out into
1594 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1595 STATUS_PROC_NAME_FMT.
1597 (procfs_notice_signals): now a necessary wrapper around
1598 (notice_signals): which are the new guts for noticing signals
1599 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1600 determine whether or not to attempt to open the ctl_fd.
1601 (procfs_read_status): new local function, reads procfs status
1602 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1603 (procfs_write_pckill): new local function, writes a PCKILL
1604 (unconditionally_kill_inferior): remove signo since we now
1605 just call procfs_write_pckill().
1606 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1607 (proc_iterate_over_mappings): the whole function is ifdefed
1608 on UNIXWARE to keep things readable.
1610 Expanded the syscall_table to include new potential sysv4.2mp
1611 members. Note that all ifdefs of UNIXWARE should be eliminated
1612 if possible or renamed to describe what's being selected for a
1613 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1614 IRIX specific code now also checks it's not UNIXWARE.
1616 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1617 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1618 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1619 "/debug/%d" as PROC_NAME_FMT used to be
1621 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1623 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1625 * config/mn10300/tm-mn10300.h: Likewise.
1627 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1629 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1630 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1631 lousy out-of-date clone of remote.c.
1633 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1635 * remote.c: Fix problems realized while showering.
1636 * (hexnumlen): Add prototype. Use max, not min.
1637 * (remote_write_bytes remote_read_bytes): Fix max packet size
1638 calculations to properly account for packet overhead. Also handle
1639 (probably rare) case where remote_register_buf_size isn't set.
1641 * remote.c: Fix doc for `C' and `S' commands to indicate full
1643 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1645 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1646 Record size of response to fetch registers command, use this to
1647 limit size of memory read and write commands.
1648 * (push_remote_target): New function to make it possible to have
1649 another target switch to the remote target.
1650 * target.h: Add prototype for push_remote_target.
1651 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1652 for hosts which default to unsigned chars (such as SGI's).
1653 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1654 handled automatically in remote.c.
1656 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1658 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1659 find_pc_sect_function(), find_pc_sect_partial_function(): new
1660 functions for debugging overlays; pc without section is ambiguous.
1661 * breakpoint.[ch]: add section pointer to breakpoint struct;
1662 add section argument to check_duplicates(); check section as well
1663 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1664 breakpoint_thread_match(), bpstat_stop_status()];
1665 add section argument to describe_other_breakpoints();
1666 use INIT_SAL() macro to zero-out new sal structures;
1667 make resolve_sal_pc() fix up the sal's section as well as its pc;
1668 match on section + pc in clear_command() and delete_breakpoint();
1669 account for overlay sections in insert_breakpoints(),
1670 remove_breakpoint() and breakpoint_re_set_one();
1671 all this to support overlays where a PC is not unique.
1672 * exec.c: change xfer_memory() to handle overlay sections.
1673 * findvar.c: change read_var_value() to handle overlay sections.
1674 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1675 * infcmd.c: jump_command() warns against jumping into an overlay
1676 that's not in memory. Also use INIT_SAL() to initialize sals.
1677 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1678 overlay state information; Also use INIT_SAL() to init sals.
1679 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1680 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1681 memory read/writes in the range 600000 to a00000, and ff680000
1682 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1683 * maint.c: maintenance command "translate-address" supports overlays.
1684 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1685 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1686 this constitutes gdb's internal overlay mapping table. Add macro
1687 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1688 Add function find_pc_sect_section().
1689 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1690 modify address_info() with overlay smarts; add function sym_info()
1691 to support the INFO SYMBOL command (translate address to symbol(s));
1692 modify disassemble_command() to work on unmapped overlays.
1693 * source.c: use INIT_SAL() to initialize sals.
1694 * symfile.[ch]: change generic_load() to use section's LMA address
1695 instead of VMA address, for overlay sections.
1696 Add numerous functions for finding a PC's section / overlay,
1697 translating between VMA and LMA address ranges, determining if an
1698 overlay section is mapped, etc. Add several user commands for
1699 overlay debugging. Add support for a "generic" form of automatically
1700 reading overlay mapping info from the inferior (based on the default
1701 (simple) overlay manager which Cygnus provides as an example).
1702 * symtab.[ch]: add functions find_pc_sect_symtab(),
1703 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1704 for lookup; modify lookup_symbol and decode_line_1() to use them;
1705 modify find_function_start_sal() to account for overlay sections;
1706 add macro INIT_SAL() for initializing struct symtab_and_line.
1707 * target.c: fix a comment in the declaration of target_ops.
1709 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1711 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1721 SKIP_TRAMPOLINE_CODE, IGNORE_HELPER_CALL): New macros that invoke
1722 the above functions.
1723 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1724 (mips_init_frame_pc): Declare.
1725 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1726 to decide if certain library function calls should be ignored.

1849 (mips_print_register): Print double registers correctly on
1850 little-endian hosts.
1851 (mips_extract_return_value): Return double values correctly
1852 on little-endian hosts.
1854 * mdebugread.c (parse_procedure): Adjust address of procedure relative
1855 to address in file descriptor record; this accounts for constant
1856 strings that may precede functions in the text section. Remove
1857 now-useless lowest_pdr_addr from argument list and all calls.
1859 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>
