        to ISO C.  Use ATTRIBUTE_UNUSED to avoid compiler warnings.
        (dos_info): Avoid compiler warning when printing a ptrdiff_t.

        * ser-go32.c (dos_get_tty_state): Fail if the (fake) handle was
        not opened by dos_open, but let the 3 standard handles go through
        unharmed.

2000-03-14  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * eval.c (evaluate_subexp_with_coercion): Add call to

        somewhat redundant.
        (QUIT): Note that this can probably be replaced by a function.

2000-03-13  James Ingham  <jingham@leda.cygnus.com>

        Add support for a variable object that tries to evaluate itself in 
        the currently selected frame, rather than in a fixed frame.
        
        * wrapper.c,h (gdb_parse_exp_1): Added a wrapper for
        gdb_parse_exp_1.
        * varobj.h: Added USE_CURRENT_FRAME to varobj_type & changed def'n 
        of varobj_create.

        variable's type has changed (for current frame variables).
        (varobj_update): Handle the case where the variable's type has
        changed.
        (delete_variable_1): Allow for deletion of variables that have not 
        been installed yet.
        (new_root_variable): Initialize use_selected_frame variable.
        (value_of_root): This is where most of the work to handle "current 
        frame" variables was added.  Most of the complexity involves
        handling the case where the type of the variable has changed.
        (varobj_create): Add a "type" argument, to tell if the
        variable is one of these "current frame" variables.  Also protect
        call to parse_exp_1 from long jumping.
        
2000-03-13  Eli Zaretskii  <eliz@is.elta.co.il>

        * go32-nat.c (struct env387): Remove declaration.

        functions.
        (regno_mapping, sig_map, excepn_map): Add braces around inner

        (many functions): Use ATTRIBUTE_UNUSED to shut up the compiler;
        fix code which mixed signed with unsigned.
        (go32_resume): Use TARGET_SIGNAL_LAST instead of -1.
        (go32_wait): Initialize INT3_addr.
        (go32_fetch_registers): Extend all FP registers that are shorter
        than 4 bytes to 32 bits.  Support 32 standard FP registers defined

        instead of exec file name.
        (ignore): Remove unused function.
        (go32_insert_hw_breakpoint): Remove unused variables.
        (init_go32_ops): Set value of processing_gcc_compilation to 2.

Mon Mar 13 18:54:42 2000  Andrew Cagney  <cagney@b1.cygnus.com>

        From 2000-03-10 Daniel Berlin <dan@cgsoftware.com> Fix C++
        overloading, add support for seeing through references:
        * valops.c (find_overload_match): Handle STABS overloading for
        C++.
        (find_overload_match): Look in right place for function arguments
        in the debug info.
        (find_overload_match): Rather than giving up when we have >1
        perfect match, just choose one, especially since the
        recommendation GDB gives ("disambiguate it by specifying function
        signature"), is basically impossible.
        (check_field_in): STREQ->strcmp_iw
        (search_struct_field): STREQ->strcmp_iw
        (find_method_list): STREQ->strcmp_iw
        * gdbtypes.c (rank_one_type): Add ability to see through
        references.
        (rank_one_type): strcmp->strcmp_iw, because the whitespace could
        be different.
        (rank_function): Rank function properly (was doing it wrong
        before, comparing the wrong parts of the arrays)
        (rank_one_type): Change #if 0 to #ifdef DEBUG_OLOAD.
        * gdbtypes.h: Add REFERENCE_CONVERSION_BADNESS for "badness"
        associated with converting a non-reference to a reference.

        * gdbtypes.c (rank_one_type): Add comment on how to eliminate the
        #ifdef DEBUG_OLOAD.
        
2000-03-11  Mark Kettenis  <kettenis@gnu.org>

        * gnu-nat.c: Fix the formatting where indent misinterpreted `&' as
        a binary operator.
        (gnu_attach): Change error message for missing
        argument to be identical to the corresponding message in
        `inftarg.c'.  This makes the testsuite happy.

2000-03-11  Mark Kettenis  <kettenis@gnu.org>

        * i386gnu-nat.c (gnu_store_registers): Make sure the T bit in the
        %eflags isn't modified.  This fixes a bug where every call to a
        function in the program beyond the first call would fail.

Fri Mar 10 11:44:55 2000  Andrew Cagney  <cagney@b1.cygnus.com>

        * MAINTAINERS: Devolve responsibility for domain maintenance.

        hash link fields of the new minimal symbol.
        * symtab.h (struct minimal_symbol): New fields `hash_next',
        `demangled_hash_next'.
        (msymbol_hash_iw, msymbol_hash, add_minsym_to_hash_table): Declare.
        * objfiles.h (MINIMAL_SYMBOL_HASH_SIZE): New define.
        (struct objfile): New fields `msymbol_hash',
        `msymbol_demangled_hash'.

2000-03-06  Jim Blandy  <jimb@redhat.com>

        * solib.c (first_link_map_member): Doc fix.

2000-03-06  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        From  Eli Zaretskii  <eliz@is.elta.co.il>:

        * event-loop.c (poll_timers): Don't compare delta.tv_sec with
        zero, since time_t might be unsigned.

2000-03-06  Mark Kettenis  <kettenis@gnu.org>

        * i386-linux-nat.c (supply_fpregset): Mask off the reserved bits
        in *FPREGSETP.
        (convert_to_fpregset): Don't touch the reserved bits in *FPREGSETP.

2000-03-05  Mark Kettenis  <kettenis@gnu.org>

        Allow GDB to run on Linux 2.0 again.
        * config.in: Add HAVE_PTRACE_GETREGS.
        * configure.in: Check if <sys/ptrace.h> defines PTRACE_GETREGS.

        * config/i386/nm-linux.h (CANNOT_FETCH_REGISTER,
        CANNOT_STORE_REGISTER): New defines.
        * i386-linux-nat.c (have_ptrace_getregs): New variable.
        (PTRACE_XFER_TYPE, CANNOT_FETCH_REGISTER, fetch_register,
        old_fetch_inferior_registers, CANNOT_STORE_REGISTER,
        store_register, old_store_inferior_registers): Copied over from
        `inptrace.c' as a temporary measure.
        (fetch_regs, store_regs, fetch_fpregs, store_fpregs):
        Conditionalize on HAVE_PTRACE_GETREGS.  Define stubs if
        HAVE_PTRACE_GETREGS isn't defined.
        (fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails
        with EIO.
        (fetch_inferior_registers, store_inferior_registers): Fall back on
        the method use in `infptrace.c' (by calling
        old_fetch_inferior_registers and old_store_inferior_registers) if
        `have_ptrace_getregs' isn't set.

2000-03-05  Mark Kettenis  <kettenis@gnu.org>

        * i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead
        of gregset_t and fpregset_t.  Those are the only names that are
        guaranteed to specify the right types for all supported Linux
        systems out there.
        Various doc fixes and gratitious local variable renames, all in an
        attempt to stress similarities between the code and unify the
        terminology used.  Use ISO-C all over.
        (regmap): Remove trailing comma.
        (FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR.
        (convert_to_gregset): Make static.  Remove GDB_REGS argument.  It
        is unnecessary and wasn't used anyway.  All callers changed.
        (convert_to_fpregset, convert_to_xfpregset): Likewise.
        (fetch_regs, store_regs): Remove unused variable `regno'.
        (fill_fpregs): If REGNO is not -1, only update the specified
        register.
        (fetch_core_registers): Renamed from
        i386_linux_fetch_core_registers.  There is no need for a unique
        name since the function is static anyway.
        (linux_elf_core_fns): Renamed from i386_linux_nat_core_functions
        since it is more descriptive.

Sun Mar  5 19:40:27 2000  Andrew Cagney  <cagney@b1.cygnus.com>

2000-03-04  Mark Kettenis  <kettenis@gnu.org>

        Fix support for Linux/i386 signal trampolines.  The old approach
        didn't work for Linux 2.2 and beyond, and didn't work with recent
        versions of the GNU C library.
        * i386-tdep.c (LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0,

        of the signal tranmpolines used by recent versions of the GNU C
        library, and add support for RT signals.
        (LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):  New
        defines.  Moved here from config/i386/tm-linux.h.
        (i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp):
        Reimplement in terms of i386_linux_sigcontext_addr.
        * config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Removed.
        (LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):
        Moved to i386-tdep.c.
        (IN_SIGTRAMP): Redefine to call i386_linux_in_sigtramp.

        From: Thomas Zenker <thz@Lennartz-electronic.DE>
        * rdi-share/hsys.c: to compile under 4.4BSD derived systems (FreeBSD,
        NetBSD...) sys_errlist should not be declared in hsys.c.
        NEED_SYSERRLIST is set already by configure, so we can use it.
        * rdi-share/unixcomm.c: 4.4BSD derived systems define BSD, but are
        posix compliant and we should not work with the old compatibility
        stuff.  Because of that I undef BSD in case of FBSD etc and include
        sys/ioctl to get the flags.
        * rdi-share/unixcomm.c: If the TIOCEXCL flags exists set serial line
        for exclusive use.

        found found in the shared library trampoline prior to the
        loading of the shared library.)

        From 2000-01-26 Rodney Brown <RodneyBrown@pmsc.com>:
        * procfs.c: Define MERGEPID if not defined. For osf4.0e.

2000-02-15  Jason Molenda  (jsm@bugshack.cygnus.com)

        * Makefile.in (diststuff): Run 'diststuff' in doc/ subdir, not
        'do-doc'.

2000-02-15  Kevin Buettner  <kevinb@redhat.com>

        Changes for AIX 4.3:
        * rs6000-tdep.c (rs6000_fix_call_dummy): Set TOC register
        to correct value for generic dummy frames.  When using
        generic dummy frames, don't attempt to write TOC value or
        function to call into the call dummy.
        (rs6000_push_arguments): Adapt USE_GENERIC_DUMMY_FRAMES
        code to also handle the PowerOpen ABI.
        (ppc_push_return_address): Enable for all ports.
        * config/powerpc/tm-ppc-aix.h (USE_GENERIC_DUMMY_FRAMES,
        PUSH_DUMMY_FRAME, PUSH_RETURN_ADDRESS, GET_SAVED_REGISTER, 
        CALL_DUMMY_BREAKPOINT_OFFSET, CALL_DUMMY_LOCATION,
        CALL_DUMMY_ADDRESS, CALL_DUMMY_START_OFFSET): Override defaults
        provided by generic RS6000 definitions so that call dummies
        are implemented using generic dummy frames instead.

        * rs6000-nat.c (store_inferior_registers): Call exec_one_dummy_insn()
        prior to changing the stack pointer via ptrace().  Also, ignore
        attempts to store to undefined registers that are less than
        NUM_REGS.

        * rs6000-tdep.c (DUMMY_FRAME_SIZE): Change size of the dummy
        frame from 436 to 448 to account for alignment padding.
        (rs6000_push_arguments): Obtain actual register size instead
        of assuming the register is 4 bytes long.  [There's still
        more work to be done to totally remove the 4 byte assumption,
        however.]  Make sure the stack is 16 byte aligned as required
        by the PowerOpen ABI.  Also, make sure that small structures
        passed in registers are properly aligned within the register.

2000-02-15  Jesper Skov  <jskov@cygnus.co.uk>

        Patch applied by Kevin Buettner <kevinb@redhat.com>

        registers to local variable registers.

2000-02-14  Jim Kingdon  <kingdon@redhat.com>

        * elfread.c (elf_symtab_read): Revert changes by Amit S. Kale.  A

2000-02-10  Mark Kettenis  <kettenis@gnu.org>

        * gnu-nat.c: Remove hackery to include <bits/waitflags.h>.  It is
        no longer necessary now we have gdb_wait.h.

2000-02-09  Mark Kettenis  <kettenis@gnu.org>

        * gnu-nat.c (proc_string): Make global.

        the proc server itself.

2000-02-10  Jim Kingdon  <kingdon@redhat.com>

        * defs.h (MERGEPID): Added.  Patch submitted by Andrew Hobson and

        * configure.in: Remove the addition of sol-thread.c to the
        CONFIG_INITS list. This caused problems with init.c, because
        sol-thread.c would be grepped twice for _initialize_* functions.
        * configure: Ditto.
        * Makefile.in: Add FIXME for init.c.

2000-02-07  Jim Kingdon  <kingdon@redhat.com>

        form.

2000-02-01  Elena Zannoni  <ezannoni@kwikemart.cygnus.com>

        * remote.c (getpkt_sane): New function. It is the old getpkt(),
        which now returns a timeout indication.
        (getpkt): New function. Wrapper for getpkt_sane(), so that return
        value can still be ignored.

Tue Feb  1 18:47:31 2000  Andrew Cagney  <cagney@b1.cygnus.com>

        * top.c (print_gdb_version): Print ``UI_OUT'' when configured with

        quotes or parenthesis terminate the line spec.  Don't use pp when
        removing the final double quote of a double-quoted string.  Don't

        this change is correct; probably we've just moved this function
        from one buggy place to another buggy place, and never came within
        an outhouse whiff of correctness.
        (find_toplevel_char): New function.

2000-01-27  Fernando Nasser  <fnasser@totem.to.cygnus.com>
