1483 Tue Apr 15 15:31:09 1997 Stan Shebs <shebs@andros.cygnus.com>
1485 * remote.c (get_offsets): Don't use scanf for interpreting
1486 response to qOffsets.
1488 Tue Apr 15 14:51:04 1997 Ian Lance Taylor <ian@cygnus.com>
1490 * gdbserver/Makefile.in (INSTALL_XFORM): Remove.
1491 (INSTALL_XFORM1): Remove.
1492 (install-only): Use $(program_transform_name) directly, rather
1493 than using $(INSTALL_XFORM) and $(INSTALL_XFORM1).

1510 Mon Apr 14 11:55:27 1997 Geoffrey Noer <noer@pizza.cygnus.com>
1512 * config/i386/cygwin32.mh: remove -lkernel32 from XM_CLIBS
1513 since gcc automatically includes it
1515 Thu Apr 10 13:20:53 1997 Geoffrey Noer <noer@cygnus.com>
1517 * procfs.c: Substantial (but incomplete) changes to support
1518 sysv4.2mp procfs as implemented in UnixWare 2.1. The procinfo
1519 struct now has substructs like struct flt_ctl instead of
1520 just a fltset_t and has a ctl_fd, status_fd, as_fd, and
1521 map_fd instead of a single fd. Non-sysv4.2mp procfs models
1522 still have the structs and multiple fds, but don't use the
1523 entire struct and the four fds all point to the same thing.
1524 We use PROCFS_USE_READ_WRITE to decide whether to talk to
1525 procfs with reads/writes or use ioctl instead. We use
1526 HAVE_MULTIPLE_PROC_FDS to determine whether procfs really has
1527 multiple fds or not. PROC_NAME_FMT is split out into
1528 CTL_PROC_NAME_FMT, AS_PROC_NAME_FMT, MAP_PROC_NAME_FMT,
1529 STATUS_PROC_NAME_FMT.
1531 (procfs_notice_signals): now a necessary wrapper around
1532 (notice_signals): which are the new guts for noticing signals
1533 (open_proc_file): gets a new flag arg used in sysv4.2mp to
1534 determine whether or not to attempt to open the ctl_fd.
1535 (procfs_read_status): new local function, reads procfs status
1536 (procfs_write_pcwstop): new local function, writes a PCWSTOP
1537 (procfs_write_pckill): new local function, writes a PCKILL
1538 (unconditionally_kill_inferior): remove signo since we now
1539 just call procfs_write_pckill().
1540 (procfs_xfer_memory): call lseek with SEEK_SET rather than 0
1541 (proc_iterate_over_mappings): the whole function is ifdefed
1542 on UNIXWARE to keep things readable.
1544 Expanded the syscall_table to include new potential sysv4.2mp
1545 members. Note that all ifdefs of UNIXWARE should be eliminated
1546 if possible or renamed to describe what's being selected for a
1547 bit better. Sysv4.2mp and IRIX both have SYS_sproc so the
1548 IRIX specific code now also checks it's not UNIXWARE.
1550 * config/i386/tm-i386v42mp.h: also define HAVE_PSTATUS_T,
1551 HAVE_NO_PRRUN_T, PROCFS_USE_READ_WRITE, and UNIXWARE
1552 * config/mips/nm-irix4.h: set CTL_PROC_NAME_FMT et al to
1553 "/debug/%d" as PROC_NAME_FMT used to be
1555 Wed Apr 9 11:36:14 1997 Jeffrey A Law (law@cygnus.com)
1557 * mn10300-tdep.c: Almost completely rewritten based on mn10200
1559 * config/mn10300/tm-mn10300.h: Likewise.
1561 Tue Apr 8 10:45:24 1997 Stu Grossman (grossman@critters.cygnus.com)
1563 * config/pa/{hppabsd.mt hppahpux.mt hppaosf.mt}: Remove
1564 remote-pa.o from TDEPFILES. Nobody uses it, and besides, it's a
1565 lousy out-of-date clone of remote.c.
1567 Fri Apr 4 08:21:21 1997 Stu Grossman (grossman@critters.cygnus.com)
1569 * remote.c: Fix problems realized while showering.
1570 * (hexnumlen): Add prototype. Use max, not min.
1571 * (remote_write_bytes remote_read_bytes): Fix max packet size
1572 calculations to properly account for packet overhead. Also handle
1573 (probably rare) case where remote_register_buf_size isn't set.
1575 * remote.c: Fix doc for `C' and `S' commands to indicate full
1577 * (remote_ops extended_remote_ops remote_desc remote_write_size):
1579 * (remote_fetch_registers remote_write_bytes remote_read_bytes):
1580 Record size of response to fetch registers command, use this to
1581 limit size of memory read and write commands.
1582 * (push_remote_target): New function to make it possible to have
1583 another target switch to the remote target.
1584 * target.h: Add prototype for push_remote_target.
1585 * sh-tdep.c (sh_frame_find_saved_regs): Fix sign extension bugs
1586 for hosts which default to unsigned chars (such as SGI's).
1587 * (_initialize_sh_tdep): Don't set remote_write_size. It's now
1588 handled automatically in remote.c.
1590 Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com>
1592 * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(),
1593 find_pc_sect_function(), find_pc_sect_partial_function(): new
1594 functions for debugging overlays; pc without section is ambiguous.
1595 * breakpoint.[ch]: add section pointer to breakpoint struct;
1596 add section argument to check_duplicates(); check section as well
1597 as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(),
1598 breakpoint_thread_match(), bpstat_stop_status()];
1599 add section argument to describe_other_breakpoints();
1600 use INIT_SAL() macro to zero-out new sal structures;
1601 make resolve_sal_pc() fix up the sal's section as well as its pc;
1602 match on section + pc in clear_command() and delete_breakpoint();
1603 account for overlay sections in insert_breakpoints(),
1604 remove_breakpoint() and breakpoint_re_set_one();
1605 all this to support overlays where a PC is not unique.
1606 * exec.c: change xfer_memory() to handle overlay sections.
1607 * findvar.c: change read_var_value() to handle overlay sections.
1608 * frame.h: declaration for block_for_pc_sect() [blockframe.c].
1609 * infcmd.c: jump_command() warns against jumping into an overlay
1610 that's not in memory. Also use INIT_SAL() to initialize sals.
1611 * infrun.c: wait_for_inferior() sets a flag to invalidate cached
1612 overlay state information; Also use INIT_SAL() to init sals.
1613 * m32r-rom.c: modify load routines to use LMA instead of VMA.
1614 * m32r-stub.c: mask exit value down to 8 bits; screen out any
1615 memory read/writes in the range 600000 to a00000, and ff680000
1616 to ff800000 (hangs because nothing is mapped there); fix strcpy().
1617 * maint.c: maintenance command "translate-address" supports overlays.
1618 * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays.
1619 * objfiles.[ch]: add ovly_mapped field to the obj_section struct;
1620 this constitutes gdb's internal overlay mapping table. Add macro
1621 ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays.
1622 Add function find_pc_sect_section().
1623 * printcmd.c: modify print_address_symbolic() with overlay smarts;
1624 modify address_info() with overlay smarts; add function sym_info()
1625 to support the INFO SYMBOL command (translate address to symbol(s));
1626 modify disassemble_command() to work on unmapped overlays.
1627 * source.c: use INIT_SAL() to initialize sals.
1628 * symfile.[ch]: change generic_load() to use section's LMA address
1629 instead of VMA address, for overlay sections.
1630 Add numerous functions for finding a PC's section / overlay,
1631 translating between VMA and LMA address ranges, determining if an
1632 overlay section is mapped, etc. Add several user commands for
1633 overlay debugging. Add support for a "generic" form of automatically
1634 reading overlay mapping info from the inferior (based on the default
1635 (simple) overlay manager which Cygnus provides as an example).
1636 * symtab.[ch]: add functions find_pc_sect_symtab(),
1637 find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line()
1638 for lookup; modify lookup_symbol and decode_line_1() to use them;
1639 modify find_function_start_sal() to account for overlay sections;
1640 add macro INIT_SAL() for initializing struct symtab_and_line.
1641 * target.c: fix a comment in the declaration of target_ops.
1643 Thu Apr 3 10:31:12 1997 Mark Alexander <marka@cygnus.com>
1645 * mips-tdep.c (mips_in_call_stub, mips_in_return_stub,

1656 the above functions.
1657 (INIT_FRAME_PC_FIRST): Change to invoke mips_init_frame_pc.
1658 (mips_init_frame_pc): Declare.
1659 * infrun.c (wait_for_inferior): Use new IGNORE_HELPER_CALL macro
1660 to decide if certain library function calls should be ignored.

1790 strings that may precede functions in the text section. Remove
1791 now-useless lowest_pdr_addr from argument list and all calls.
1793 Fri Mar 21 15:36:25 1997 Michael Meissner <meissner@cygnus.com>

2407 * mn10300-tdep.c: made a lot more generic, ripping out code
2408 from copied target (no more mn10300_scan_prologue,
2409 init_extra_frame_info, and mn10300_fix_call_dummy calls)
2410 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
2411 and INIT_FRAME_PC macros

2415 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
2416 FP_REGISTER_BYTES to compute offsets into the saved frame,
2417 since it fails for SPARC targets configured without any
2418 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.

2428 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS
2430 * configure configure.in: Clean up test cases around thread support.
2431 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if
2433 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c

2438 * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section
2439 instead of read_memory. It takes a bfd_section arg.
2440 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
2441 unnecessary cast for assignment of struct dbx_symfile_info.
2442 Struct objfile now uses a real pointer instead of PTR for this
2444 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
2445 text, data and bss into dbx_symfile_info.

2456 * (print_formatted x_command): Record current section along with
2457 current address for repeated commands.
2458 * sparc-nat.c (fetch_inferior_registers): Change
2459 target_xfer_memory to target_{read write}_memory to allow changes

2465 * symtab.h (struct general_symbol_info): Add bfd section to
2467 * target.c target.h (target_xfer_memory): Add bfd section to
2469 * (target_read_memory_section): New routine to read data from a
2471 * (target_memory_bfd_section): New global variable to pass bfd
2472 section in to targets.
2473 * valarith.c (value_add value_addr value_array): Preserve bfd
2474 section when computing new value.
2475 * value.h (struct value): Add bfd section to values.
2476 * values.c (allocate_value value_copy): Initialize/preserve bfd

2488 * mn10300-tdep.c (mn10300_push_arguments): rewrote,
2489 also removed code elsewhere that made use of RP_REGNUM.
2490 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
2491 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
2492 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
2493 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
