1345 (There are still more of these in other files.)
1346 * main.c (defined_command): Lower-case the user's
1347 new command before entering it. Needed because
1348 command lookup is case-insensitive (and also lower-cases).
1349 (Based on Metin's earlier patch.)

1378 continuation in yet another place (between method declarations).
1380 Mon Mar 23 23:01:41 1992 Stu Grossman (grossman at cygnus.com)
1382 * mips-tdep.c: include symfile.h and objfiles.h to fix
1385 Mon Mar 23 15:49:14 1992 Per Bothner (bothner@cygnus.com)
1387 * valops.c (value_struct_elt_for_reference): Added 'offset'
1388 parameter to handle multiple inheritance.

1455 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
1457 More C++ improvements (pointers to members, qualified names).
1458 * c-exp.y: Support exp.type::name and exp->type::name
1459 syntaxes. (Unfortunately, doesn't work for static members.)
1460 * c-exp.y, eval.c: Make type::~type work better.
1461 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
1462 value_static_field by value_struct_elt_for_reference.
1463 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
1464 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
1465 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
1466 for OP_SCOPE operand; no point in it now that we use lazy
1467 reading of values, and use "reference to member" objects.
1468 * gdbtypes.h: Clarify comment.
1469 * valops.c: Change value_struct_elt_for_address to return
1470 a reference (or variable), rather than a pointer. Change
1471 the name to value_struct_elt_for_reference to reflect this.
1472 Returning a reference instead of a address provides a
1473 generalization, since we can use the routine for both
1474 class::name as well as &class::name.
1475 Also, recurse to handle multiple inheritance properly.
1476 * valprint.c: Moved code to print pointer-to-members
1477 to new function point_class_member. This allows a
1478 "reference-to-member" to be printed using the same code.

1480 "struct " for domains of class-member types.

1482 version of value_static_field (which can then be deleted).
1483 * value.h: Rename value_struct_elt_for_address to
1484 value_struct_elt_for_reference. Delete value_static_field.
1485 * values.c: Remove no longer used function value_static_field.

1492 the xxxx_sym_fns vector to a standard format and add comments.
1493 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
1494 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
1495 Pass pointer to struct objfile rather than pointer to sym_fns.
1496 Change references inside each function accordingly. Allocate any
1497 symbol file specific info in the per-objfile memory region.
1498 * dbxread.c (free_and_init_header_files): Break function into
1499 free_header_files(), called from dbx_symfile_finish(), and
1500 init_header_files(), called from dbx_new_init().
1501 * dbxread.c (dbx_new_init): Move deallocation things to new
1502 dbx_symfile_finish function.
1503 * elfread.c (elf_new_init): Call buildsym_new_init().
1504 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
1505 routine for the objfile before deallocating other stuff.
1506 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
1507 * symfile.h: Move struct sym_fns to before struct objfile def.
1508 Add sym_finish function pointer and change prototypes of other
1509 function pointers to reflect passing struct objfile pointer rather
1510 than struct sym_fns pointer.
1511 * symfile.c: Remove now obsolete symtab_fns pointer.
1512 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
1513 locates the correct sym_fns struct for the given objfile.
1514 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
1515 for better support of mapped symbol tables.
1516 * symfile.c (symbol_file_command): Remove obsolete code using
1518 * symfile.h: Remove duplicate declarations for symfile_objfile,
1519 entry_point, and object_files.
1520 * target.c (target_info): Compare symfile_objfile to NULL.
1521 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
1522 aixcoff_symfile_finish().

1534 * symtab.c: Other fixes to improve handing of operators.
1535 * valprint.c (type_print_base): Fix test for constructor.
1536 * values.c (value_static_field): Allow evaluation of
1537 CLASS::METHOD, returning a function pointer.

1746 * infrun.c (wait_for_inferior): Compare int tmp to int 0,
1747 not NULL, which can be (void *).
1748 * tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
1749 * tm-i386v.h (SP_ARG0): Define
1750 * xm-sysv4.h: Back out of change for missing prototypes.
1751 * i386-tdep.c (get_longjmp_target): Add function.
1753 Wed Mar 4 05:46:11 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1755 * Makefile.in: install man page too.
1757 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
1759 * All GDB files that #include defs.h: Removed stdio.h.
1760 (defs.h): #include stdio.h.
1762 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
1764 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
1765 a ptype to reflect the setting of TARGET_PTR_BIT. Set the
1766 TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
1767 * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
1768 * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
1769 it before printing out the hex shape of an address.
1771 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
1773 * rs6000-xdep.c (frame_initial_stack_address): Move
1774 code to set frame->cache_fsr into new separate function
1775 frame_get_cacahe_fsr. This allows fixing a fatal error.
1776 * xcoffexec.c: Turn previously suppressed error
1777 message back on, after cleaning up BFD.
1779 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
1780 printing of blank line, since it cases printing of an
1781 extra blank line. Is this intended? It does mess up
1783 * defs.h: Put back declarations of malloc and realloc,
1784 but protected by #ifndef MALLOC_INCOMPATIBLE.
1785 * objfiles.c: Undo previous change: Use malloc/realloc
1786 for objfile malloc/realloc fields (but add a cast).
1787 * xcoffexec.c: Suppress an error message (for now).
1789 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
1791 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1792 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
1793 * buildsym.c: Use smash_to_pointer_type() to handle forward type
1795 * xcoffread.c: Modifications to C_DECL storage class handling, and
1796 introduction of an old smash_to_pointer_type() routine.
1798 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1799 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
1800 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
1801 parameters have been modified.
1803 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1804 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
1805 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
1806 and fetch_inferior_registers() always fetched all the registers
1807 resulting valid register values at hand all the time. Pushing a dummy
1808 frame did not require validating all register values first. After
1809 putting the above mechanism into action, we didn't have valid registers
1810 values always ready. Thus, all registers need to be fetched before
1811 pushing a dummy frame now.
1813 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1814 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
1815 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
1816 the starting address (actual frame address) of a frame.
1817 * rs6000-tdep.c: modifications to function_frame_info() to see if
1818 function reserves a frame pointer register (alloca register)
1819 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
1820 FRAME_LOCALS_ADDRESS has been updated to support debugging of
1821 functions with alloca() calls.
1823 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
1825 * xm-sysv4.h: Provide definitions/prototypes for host environment
1826 functions for which no definitions or prototypes are provided in
1827 any currently included gdb or host environment header files.
1828 For SVR4, this currently includes malloc and realloc, which cannot
1829 be portably prototyped in any gdb include file.
1831 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
1833 * buildsym.h: Remove obsolete variable file_stabs.
1835 * Makefile.in: Move place where configure merges in host-
1836 and target-dependent fragments later, so the latter
1837 can override (say) GNU_MALLOC.
1838 * config/mh-rs6000: Use system malloc. Otherwise, I
1839 ended up with *two* incompatible versions of malloc
1840 (functions in libc would call the malloc in libc).
1841 I assume this is a shared library problem.
1843 * remote.c: Fix (presumed) typo.
1844 * objfiles.c: Use xmalloc/xrealloc instead of
1845 malloc/realloc (since the latter are no longer declared).
1847 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1848 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
1849 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
1850 handle individual registers.
1851 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
1852 correctly in case it wasn't cached yet. (A problem showed up
1853 after fetching individual registers.)
1854 * buildsym.c: Disable type_synonym_name's type name overwriting
1855 in cases it is unnecesary. rs6000 portation doesn't use
1856 type_synonym_name, and it used to nullify type names
1857 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
1858 type's name as soon as space for that type is allocated.
1859 * xcoffread.c: ignore a section's lineno information if it is
1860 not `.text'. (In rs6000 bfd portation integration, skipping over
1861 `.pad' sections are ignored since it was in machine independent
1862 part of the code. Thus, a problem of fake sections with invalid
1863 lineno information arised.)
1865 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1866 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
1867 * rs6000-tdep.c: make function_frame_info() work whether or not
1868 reading from a core file.
1869 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
1871 * infrun.c. main.c, printcmd.c. symtab.c:
1872 More changes from IBM for rs6000.
1875 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
1877 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
1878 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
1879 Merge in changes (mostly from IBM) for RS6000.
1880 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
1881 More changes from IBM for RS6000. These are in machine-
1882 independent code, and probably could do with some cleaning
1883 up. The most questionable of these are #ifdef IBM6000.
1884 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
1885 to single_step() (for consistency with rs6000 and i860).
1886 * utils.c: Allow the 1st arg to xrealloc to be NULL
1887 (in which case do malloc). This removes the need for
1888 some tests in xcoff code (and perhaps other places?).
1889 * coffread.c: Removed variables last_source_file,
1890 type_vector, and type_vector_length as these are now
1891 defined by buildsym.[ch].
1892 * defs.h: Remove prototypes for malloc and realloc, since
1893 these should only be used to implement xmalloc and xrealloc,
1894 and they conflict with <stdlib.h> in AIX - where they
1895 return void* even when __STDC__ isn't defined. Sigh.
1896 * munch: Recognize *initialize* in data as well as text
1897 (AIX uses data). Also, incorporate a patch from Garrett
1898 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
1899 much more sensible, by only trying to match the name of
1900 the initialize_foo function, and not the junk before it.
1902 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
1904 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
1905 unless symbol table indicates that something has changed.
1907 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
1909 * remote.c: Make it work for embedded MIPS. Increase buffer
1910 size, and use throughout. Round buffer size up if too many regs.
1911 Support baud rate setting and try for an 8-bit path. If
1912 interrupted while waiting for target, send a ^C down the wire.
1913 Avoid single-byte reads.
1914 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
1916 * mips-xdep.h: Avoid the embedded regs when on Unix.
1918 * mipsread.c: Byte-swap the symbol table structures, using
1919 routines from ecoff.c, to read a symbol table written in any
1920 of the four possible byte orders.
1921 * configure.in (mips-big-* target): Same as Sony News.
1922 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
1923 * ecoff.c: New file for symbol swapping routines.
1925 Thu Feb 27 09:26:38 1992 Stu Grossman (grossman at cygnus.com)
1927 * breakpoint.c (all_breakpoints_info, breakpoint_1): Add 'info
1928 all-breakpoints' command.
1929 * (get_number): Allow users to enter negative breakpoint numbers.
1930 * (breakpoint_1): Reformat display of 'info break' to show new
1932 * (create_longjmp_breakpoint, breakpoint_re_set,
1933 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
1934 symfile.c (syms_from_objfile): Re-do
1935 insertion of longjmp breakpoints. Move all code into
1936 breakpoint_re_set, and call that instead of
1937 create_longjmp_breakpoint in symfile.c.
1939 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
1941 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.
1942 * breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
1943 * symtab.c (find_pc_symtab): Handle having no objfiles.
1944 * infcmd.c: Fix comment.
1945 * objfiles.c (free_all_objfiles): Add.
1946 * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE): Add.
1947 * symfile.c (symbol_file_command): free all objfiles when
1948 specifying a new symbol file.
1949 (reread_symbols): Stat the file name, don't fstat the descriptor.
1951 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1953 * Makefile.in, configure.in: removed traces of namesubdir,
1954 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1955 copyrights to '92, changed some from Cygnus to FSF.
1957 Tue Feb 25 19:31:19 1992 Stu Grossman (grossman at cygnus.com)
1959 * dbxread.c (end_psymtab): Delete empty psymtabs.
1960 * symfile.c (allocate_psymtab): Recycle empty psymtabs.
1961 * symfile.h (struct objfile): Add free_psymtabs.
1963 Sat Feb 22 02:00:32 1992 John Gilmore (gnu at cygnus.com)
1965 * Makefile.in (VERSION): Roll to gdb-4.4.4.
1967 * symfile.c (symbol_file_command): strcmp => !strcmp.
1968 * breakpoint.h: Move prototypes to follow enum definition they need.
1969 * breakpoint.c, infrun.c: Lint.
1970 * printcmd.c: Use `enum enable' rather than `enum
1972 * mipsread.c: First pass at making it compile with the new
1973 objfile changes. Probably seriously broken still, but it
1976 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

1980 mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
1981 stepping (and nexting) through longjmp(). Also, cleanup
1982 breakpoint handling quite a bit by creating explicit breakpoint
1983 types instead of using magic breakpoint numbers.
1984 Makefile.in: Update version to 4.4.3
1986 Sat Feb 22 00:08:50 1992 John Gilmore (gnu at cygnus.com)
1988 * buildsym.c, dwarfread.c, gdbtypes.c, inflow.c, main.c,
1989 minsyms.c, printcmd.c, remote.c, saber.suppress: Saberlint.
1990 * symmisc.c, xcoffread.c: Move debug functions to symmisc.c.
1992 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
1994 * minsyms.c (install_minimal_symbols): Add bunches to any
1995 existing minsyms in the objfile. Avoid extra mallocation
1996 by working directly in the obstack. Remove ignored `mainline' parm.
1997 * coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
1998 xcoffread.c: Change all callers.

2000 symbol readers now, with a small bit of work.
2002 * valops.c, value.h: Lint.
2003 * remote-vx.c: Add missing break; statement. Bugfix by
2004 Michael Sclafani, <sclafani@src.dec.com>.

2369 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
2370 Remove to_call_function and target_call_function, since it
2371 always calls the same thing (call_function_by_hand).
2372 * core.c, exec.c, solib.c: Rename target_ops sections =>
2374 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
2375 target.h: target_kill takes no args.
2376 * language.c (language_info): Scaffolding to allow briefer
2377 messages when the current language changes. FIXME.

2406 * coffread.c (decode_base_type): Pass long, not union.

2441 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
2443 * mipsread.c (parse_partial_symbols): Handle dependencies
2444 between partial symbol tables (when not doing stabs-in-ecoff).
2445 (This used to be handled by parse_fdr, but parse_fdr was
2446 incompatible with handling stabs-in-ecoff, so the code
2447 was re-written to not use parse_fdr. Unfortunately,
2448 the logic to handle dependencies was overlooked.)
2450 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2452 * coffread.c (read_enum_type): Use the size of a target int when
2454 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
2456 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
2457 * symtab.c (lookup_reference_type, lookup_ptr_type): use
2458 TARGET_PTR_BIT to determine size of a pointer
2459 * values.c (unpack_long): when unpacking a REF or a PTR don't
2460 assume the size of the type.
2462 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
2464 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
2465 looking at its members. Improve guess between struct and union,
2466 only assuming union if multiple members have offsets of zero.
2468 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
2470 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
2471 (This is just for clarity - and one day permitting us to
2472 change FP0_REGNUM from 38 to 32, which would make more sense.)
2473 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
2474 register numbers in stabs-in-ecoff get handled correctly.
2476 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
2478 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
2479 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
2480 into BSD and Ultrix.
2482 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
2484 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
2486 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
2488 * Makefile.in: Increment version to 4.4.1.
2489 * main.c (print_gdb_version): Update copyright notice.
2491 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
2493 * mipsread.c: Prepend "struct " to the names of structure
2494 types, and similarly for enums and unions. (This used
2495 to be done, but got lost in the re-write to "guess" the
2496 difference between enum/struct/union.)
2497 Also, guess that a tag is an enum if the first member
2500 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
2502 * xm-vax.h: #ifndef ultrix around #include of endian.h and
2505 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
2507 * Projects: Patching executables is done.
2508 * Makefile.in (VERSION): Roll to gdb-4.4.
2509 * README, WHATS.NEW: Update for gdb-4.4.
2511 * symfile.c (reread_symbols): Whenever we reread one object
2512 file's symbols, we must restart the scan, because the object_files
2513 chain has been permuted.
2515 * exec.c (exec_files_info): Split out into print_section_info.
2516 Print BFD filename of each section if it's not the default one.
2517 * core.c (core_files_info): Call print_section_info.
2519 * xm-vax.h: Include a few system header files whose definitions
2520 must precede defs.h.
2521 * language.c, language.h: Make some things const.
2522 * expression.h, main.c: const spreads like ooze.
2524 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
2525 since BREAKPOINT values can be >0x80.
2527 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
2529 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
2531 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
2533 * sparc-pinsn.c: Remove kludge for preferring architectures.
2534 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
2535 and forever. Add `add' instruction to the set that get checked
2536 for a preceding `sethi' in order to print an absolute address.
2537 Corresponding changes in ../include/opcode/sparc.h needed
2538 to eliminate garbage instructions.
2540 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
2542 * mipsread.c (parse_partial_symbols): Make sure partial
2543 symbols are created for external symbols (as used to be
2544 the case). This is a bit of a pain with the mips-coff.
2545 It uses a table which points to all of the external
2546 symbols belonging to a particular FDR or psymtab.
2547 Once we've generated this table, we might as well save
2548 it, and then use it in psymtab_to_symtab_1 to find
2549 the symbols to pass to parse_external().
2550 * symfile.c, symfile.c: New function start_psymtab_common
2551 to share the common parts of allocating a new psymtab
2552 for dbxread, mipsread (and later dwarfread). Its code
2553 was pulled out from start_psymtab in dbxread.c.
2554 * dbxread.c (start_psymtab): Use start_psymtab_common().
2556 * valprint.c (val_print): If there is an error when trying
2557 to print a string, check to see if there really is a problem
2558 by reading just one character. If that works, assume

2575 Handle debug symbols in dynamically loaded (relocated) code:
2577 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
2578 offset to process_one_symbol.
2579 (process_one_symbol): Take new offset parameter. Add it into
2580 appropriate symbol types to relocate symbols to loaded addresses.

2582 we don't expect to see.
2583 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
2584 process_one_symbol (FIXME, should pass real offset).

2675 New files for stratus. Not complete enough to actually build
2676 on the Stratus machine; that awaits copyright assignment for
2679 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
2680 for getting custom flags into CFLAGS when doing makes.
2682 * configure.in: Add config information for stratus.

2709 nexting over recursive function calls.
2711 * target.c (target_read_string): Create this routine to read null
2712 terminated strings from the target. It deals with running off the
