Fri Apr 30 16:50:38 1993  K. Richard Pixley  ([email protected])

        * 29k-share/udip2soc.c (UDIConnect): replace union wait with int.

          required target ports which use sockets (like a29k-udi).

        * remote-udi.c (udi_wait): Use SIGURG, as Solaris doesn't have SIGLOST.

Fri Apr 30 11:05:42 1993  Jim Kingdon  ([email protected])

        CC_HAS_LONG_LONG.
        * printcmd.c (print_scalar_formatted):  Call print_longest

        config subdirectory name.  Similarly, handle gdb_target_cpu.
        Modify configure.in as appropriate to make use of gdb_host_cpu
        and gdb_target_cpu to find makefile fragments and make links.

          this algorithm from first hit to tightest fit.

        * mips-tdep.c (heuristic_proc_start): if we walk the pc into the
          fence post without finding the enclosing function, then print a
          warning.

Thu Mar 11 09:33:01 1993  Fred Fish  ([email protected])

        * utils.c (fputs_demangled, fprint_symbol):  Remove.
        * utils.c (fprintf_symbol_filtered):  New function which combines
        the functionality of fputs_demangled and fprint_symbol.  Uses a
        caller provided language parameter to select the appropriate 
        demangler, and caller provided args to pass to the demangler.
        * defs.h (enum language):  Move further up in file so enum can
        be used in prototypes.
        * defs.h (fputs_demangled, fprint_symbol):  Remove prototypes.
        * defs.h (fprintf_symbol_filtered):  Add prototype.

        * Makefile.in (VERSION):  Bump version to 4.8.2.

        * main.c (source_command):  Require an explicit pathname of file

        was troublesome and undocumented.
        * printcmd.c (disassemble_command):  Add missing '{}' pair to
        else with two statements.  Bug reported by Stephane Tsacas
        <[email protected]>.
        * symtab.c (find_pc_line):  Don't complain about zero length or
        negative length line numbers for the moment, since we may not own
        the terminal when called, such as when single stepping.  (FIXME)
        * language.h (CAST_IS_CONVERSION):  True if current language is
        C++ as well as C.  Fix from Peter Schauer.
        * environ.c (get_in_environ, set_in_environ, unset_in_environ):
        Use STREQN macro rather than bare '!strncmp()'.
        * environ.c (unset_in_environ):  Avoid use of memcpy on

        <[email protected]>.
        * c-exp.y (%union struct):  Remove unused ulval as suggested
        by Paul Eggert <[email protected]>.

Sun Mar  7 21:58:53 1993  Ian Lance Taylor  ([email protected])

        * Makefile.in (MAKEOVERRIDES): Define to be empty for GNU Make

Fri Mar  5 17:16:26 1993  K. Richard Pixley  ([email protected])

        * tm-irix3.h (ZERO_REGNUM): copy this macro from tm-mips.h so that
          irix4 will again compile.

        * tm-mips.h (GDB_TARGET_IS_MIPS): no longer used, now removed.

        * configure.in: accept mips-sgi-irix4* for irix4.

        * z8k-tdep.c (print_register_hook): Lint.

Thu Mar  4 17:42:03 1993  John Gilmore  ([email protected])

        Lint fixes from Paul Eggert ([email protected]):

        * command.c (do_setshow_command):  var_uintegers are unsigned.
        * sparc-tdep.c (save_insn_opcodes, restore_insn_opcodes): 
        unsigned, since they use hex values with the high bit set.

Thu Mar  4 08:22:55 1993  Fred Fish  ([email protected])

        Fixes submitted by Karl Berry ([email protected]):
        * m88k-pinsn.c (sprint_address):  Use SYMBOL_NAME macro to
        access symbol name.  
        * m88k-nat-c (SXIP_OFFSET, SNIP_OFFSET, SFIP_OFFSET):  Enclose
        macro definitions in parenthesis.

        * dbxread.c (dbx_symfile_init):  Catch the case where there is
        no string table, but the only way we find out is by reading zero
        bytes from EOF.

Wed Mar  3 15:51:28 1993  Fred Fish  ([email protected])

        * dbxread.c (dbx_symfile_init):  Make size of the string table
        size field a define (DBX_STRINGTAB_SIZE_SIZE).  Ensure that the
        offset to the string table is nonzero and handle the nonexistant
        string table case, should it occur.  Ensure that the string table
        size read from the file is reasonable, with a minimum lower bound
        of DBX_STRINGTAB_SIZE_SIZE instead of zero.

Wed Mar  3 07:23:03 1993  Ian Lance Taylor  ([email protected])

        * Makefile.in: Changes to build testsuite correctly.
        (FLAGS_TO_PASS): Added CXX and CXXFLAGS.
        (CC_FOR_TARGET, CXX, CXX_FOR_TARGET): New variables.
        (TARGET_FLAGS_TO_PASS): New variable.
        (SUBDIRS): Added testsuite.
        (all): Build testsuite using TARGET_FLAGS_TO_PASS, so that
        testsuite is compiled with CC_FOR_TARGET rather than CC.

Tue Mar  2 17:57:56 1993  Fred Fish  ([email protected])

        * dbxread.c (dbx_symfile_init):  Fix for nonexistant string table,

        * config/vaxult2.mh:  New file.
        * xm-vaxult2.h:  New file.

        * c-exp.y (parse_number):  Change high_bit to unsigned.
        * demangle.c:  Change all references to cfront to ARM, since the
        actual algorithm is the one specified in the Annotated Reference
        Manual.  This was confusing users into thinking that full cfront
        support was implemented.
        * dwarfread.c (CFRONT_PRODUCER):  Remove, was never really used.
        * eval.c (evaluate_subexp):  For STRUCTOP_PTR pass the arg type
        directly to lookup_struct_elt_type, which will do the
        dereferencing itself.
        * gdbtypes.c (lookup_struct_elt_type):  Expand comments.  Fix
        NULL dereferencing bug for unnamed structs, comment out
        questionable code.
        
Mon Mar  1 17:54:41 1993  John Gilmore  ([email protected])

        * coffread.c (process_coff_symbol):  Change PCC argument correction
        so that it only happens on big-endian targets; so that it only
        happens if the short or char argument is aligned on an int
        boundary; and so that it changes the location, rather than the
        type, of the argument.  These changes tend to parallel similar
        (old) changes in stabsread.c.

        * coffread.c (coff_read_enum_type):  Use the specified size for
        enums, don't assume that they are int-sized.

        * c-valprint.c (c_val_print):  Don't assume enums are the same as
        ints.

        * coredep.c:  Handle NO_PTRACE_H in coredep.c.  Fix by Michael
        Rendell, <[email protected]>.

Wed Feb 24 07:41:15 1993  Fred Fish  ([email protected])

        * symtab.h (SYMBOL_INIT_DEMANGLED_NAME):  Initialize contents
        of demangled name fields to NULL if no demangling exists for
        a symbol.  SYMBOL_INIT_LANGUAGE_SPECIFIC does this for new
        symbols if their language is known at the time they are created,

        pointer correctly in case value_struct_elt moves it around.

        * tm-sun4sol2.h (CPLUS_MARKER):  Remove, now set in tm-sysv4.h.
        * tm-sysv4.h (CPLUS_MARKER):  By default, g++ uses '.' as the
        CPLUS_MARKER for all SVR4 systems, so follow suit.
        * defs.h (strdup_demangled):  Remove prototype.
        * dwarfread.c (enum_type, synthesize_typedef):  Use new macro
        SYMBOL_INIT_LANGUAGE_SPECIFIC.
        * dwarfread.c (new_symbol):  Use SYMBOL_INIT_DEMANGLED_NAME.
        * minsyms.c (install_minimal_symbols, prim_record_minimal_symbol,
        prim_record_minimal_symbol_and_info):  Use new macro
        SYMBOL_INIT_LANGUAGE_SPECIFIC.
        * minsyms.c (install_minimal_symbols):  Use new macro
        SYMBOL_INIT_DEMANGLED_NAME.
        * stabsread.c (define_symbol):  Use new macro
        SYMBOL_INIT_DEMANGLED_NAME.
        * symfile.c (add_psymbol_to_list, add_psymbol_addr_to_list):
        Use new macro SYMBOL_INIT_DEMANGLED_NAME.
        * symfile.h (ADD_PSYMBOL_VT_TO_LIST):  Use new macro
        SYMBOL_INIT_DEMANGLED_NAME.
        * symmisc.c (dump_msymbols, dump_symtab, print_partial_symbol):
        SYMBOL_DEMANGLED_NAME now tests language itself.
        * symtab.c (COMPLETION_LIST_ADD_SYMBOL):  SYMBOL_DEMANGLED_NAME
        now tests language itself.
        * symtab.h (SYMBOL_CPLUS_DEMANGLED_NAME):  New macro that does
        what SYMBOL_DEMANGLED_NAME used to do, directly access the C++
        mangled name member in the language dependent portion of a symbol.
        * symtab.h (SYMBOL_DEMANGLED_NAME):  New macro that returns the
        mangled name member appropriate for a symbol's language.
        * symtab.h (SYMBOL_SOURCE_NAME, SYMBOL_LINKAGE_NAME,
        SYMBOL_MATCHES_NAME, SYMBOL_MATCHES_REGEXP):
        SYMBOL_DEMANGLED_NAME now tests language itself.
        * symtab.h (SYMBOL_INIT_LANGUAGE_SPECIFIC):  New macro that
        initializes language dependent portion of symbol.
        * symtab.h (SYMBOL_INIT_DEMANGLED_NAME):  New macro that
        demangles and caches the demangled form of symbol names.
        * utils.c (fputs_demangled, fprint_symbol):  Use current language
        to select an appropriate demangling algorithm.
        * utils.c (strdup_demangled):  Remove, no longer used.
        * symtab.h (SYMBOL_CHILL_DEMANGLED_NAME):  New macro that directly
        access the Chill mangled name member in the language dependent
        portion of a symbol.
        * ch-lang.c (chill_demangle):  New function, simple demangler.
        * defs.h (chill_demangle):  Add prototype.
        * symtab.h (language_dependent_info):  Add struct for Chill.
