Tue Dec 31 06:51:43 1996  Mark Alexander  <marka@cygnus.com>

        * config/i386/xm-windows.h: Undo previous change to SIGTRAP
        and SIGQUIT values; it messed up non-MIPS targets.
        * config/mips/tm-mips.h: Undefine BREAKPOINT, replace
        with separate LITTLE_BREAKPOINT and BIG_BREAKPOINT definitions;
        this fixes problem with setting breakpoints in little-endian
        programs in the simulator.

        * sparclet-rom.c: Remove includes of Unix system files.
          Add function "sparclet_supply_register" so that parse_register_dump
          will not seg-fault by calling a null function pointer.

          Remove pointer to sparclet_load (downloading SREC's doesn't work).
          Null out local register names for %g0, all %cc and all %asr regs,
          since the monitor can't report them.  Will return zero instead.
        * sparclet-stub.c: New -- remote protocol support for sparclet CPU.

        a value whose length is less than the register size.
        Write stack arguments with a single write_memory call.
        (mips_pop_frame):  Use frame_saved_regs instead of proc_desc to

        LOC_LOCAL_ARG as arguments so that GDB will know about function
        args declared this way.  Mostly affects dwarf.
        * dwarfread.c (decode_die_type):  Change default type from int to
        void.  This allows GDB to recognize void functions.

        * dbxread.c (read_dbx_symtab end_psymtab), partial-stab.h:  Don't

        * mdebugread.c xcoffread.c:  Define textlow_not_set for

Thu Jul 11 21:13:21 1996  Mark Alexander  <marka@cygnus.com>

        * monitor.c (monitor_write_memory, monitor_read_memory_single):
        Disable use of "long long" memory read/write commands; can't
        use them because we hold the values to read/write in an int
        variable, and because strtoul fails on values that exceed the
        size of a long.  This fixes breakpoint problems on MON960.

        * gdbserver/Makefile.in: Ditto.
        * utils.c (init_malloc): Replace warning() use with direct call of
        fprintf_unfiltered, since current_target has not yet been set and thus

        defined.  Other small mmalloc related cleanups.

        * NEWS:  Add Alpha Linux as a new native configuration.

        * mdebugread.c (parse_symbol): When we find a malloc() symbol with
        return type VOID, assume no debugging info is available for that
        object file and patch the return value into VOID *.  Otherwise,
        operations requiring an implicit call to malloc() will fail.

        * infrun.c (wait_for_inferior): The criterion to detect entering a
        sigtramp handler is now: (a) the current pc is inside a sigtramp
        handler, (b) the previous pc is not in a sigtramp handler, and (c)
        the current stack pointer is "inner" than the old one.  Condition
        (c) is new to avoid mistaking a return from a signal handler into
        sigtramp as a new sigtramp invocation.

        * dcache.c (struct dcache_block): Declare addr as CORE_ADDR.  An
        int may not be big enough to hold an address.
        (dcache_hit): Ditto.
        (dcache_peek_byte): Fix indentation.

        * configure.in (alpha-*-linux*): Add target.

        xm-alphaosf.h.
        * config/alpha/alpha-osf2.mh: Ditto.

        * blockframe.c (find_pc_partial_function): Pass PC to
        SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems
        that detect sigtramp code via designated code sequences (as is the
        case for Linux/Alpha, for example).
        
        * config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END
        to ignore new PC argument.
        * config/m68k/tm-hp300bsd.h: Ditto.
        * config/vax/tm-vax.h: Ditto.

        * alpha-tdep.c (alpha_linux_sigtramp_offset): New function.
        (alpha_osf_skip_sigtramp_frame): Ditto.
        (push_sigtramp_desc): Ditto.
        (alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract
        sigcontext address from frame.
        (alpha_saved_pc_after_call): When in sigtramp, use
        alpha_frame_saved_pc() instead of read-register().
        (after_prologue): When inside a dynamically generated sigtramp
        function, there is no prologue, so return address of first
        instruction.
        (alpha_in_prologue): Fix typo in comment.
        (find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine
        whether we're inside a dynamicaly generated sigtramp function.  If
        so, create and push and appropriate procedure descriptor.
        (alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain
        the frame past a sigtramp frame (if the current frame is indeed a
        sigtramp function).
        (init_extra_frame_info): Don't read next frame register off of
        stack-pointer when inside a dynamiccaly generated sigtramp.
        (alpha_pop_frame): Also unlink and destroy procedure descriptors
        created for dynamically generated sigtramp functions.

        * alpha-nat.c: When compiling under Linux, include <asm/reg.h> and
        <alpha/ptrace.h> instead of <machine/reg.h>

Tue Jul  2 13:58:10 1996  Miles Bader  <miles@gnu.ai.mit.edu>

        of the file just loaded.

        * configure: Regenerate with autoconf.
        * config.in: Regenerate with autoheader.
        * main.c (main): Only use sbrk() when HAVE_SBRK is defined.

Fri Apr 12 09:45:29 1996  Stu Grossman  (grossman@critters.cygnus.com)

        * defs.h:  Define TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT
        defaults for bi-endian targets.  Replace function pointers for
        floatformat routines with macros.  No need for these to be runtime
        selectable.
        * findvar.c:  Get rid of floatformat function pointers.  Use
        macros in extract_floating and store_floating.
        * remote-nindy.c (nindy_fetch_registers nindy_store_registers):
        Use floatformat macros.

Thu Apr 11 21:28:02 1996  Fred Fish  <fnf@cygnus.com>

        From: Miles Bader  <miles@gnu.ai.mit.edu>
        * configure.in (AC_CHECK_HEADERS): check for endian.h.
        Use AC_CHECK_TOOL to find AR & RANLIB.  Add AC_PROG_AWK.
        Add host & target cases for i[345]86-*-gnu*.
        * config.in: Regenerate with autoheader.
        * configure: Regenerate with autoconf.
        * Makefile.in (AR, AWK): Set from corresponding autoconf substs.
        (init.c): Don't scan mig-generated files.
        * defs.h (endian.h): Include if HAVE_ENDIAN_H defined.
        * config/nm-m3.h (ATTACH_NO_WAIT): Define.
        * infcmd.c (attach_command): Use "#ifndef ATTACH_NO_WAIT"

        * (dcache_peek dcache_fetch dcache_poke):  Make dcache_fetch and
        dcache_poke call dcache_xfer_memory directly in order to fix
        problems with turning off dcache.  dcache_peek is now unnecessary,
        so it goes away.

        * defs.h:  Define new macros HOST_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT 
        and TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT to specify a pointer
        to a struct floatformat.  This allows for better handling of
        targets whose floating point formats differ from the host by more
        than just byte order.
        * (floatformat_to_long_double floatformat_from_long_double):
        Prototypes for new functions in utils.c.
        * (floatformat_to_doublest floatformat_from_doublest):  Prototypes
        for pointers to floating point conversion functions.  The actual
        function uses either double or long double if the host supports it.
        * findvar.c (floatformat_to_doublest floatformat_from_doublest):
        Initialize to point at correct function depending on HAVE_LONG_DOUBLE.
        * (extract_floating store_floating):  Rewrite.  Now, if host fp
        format is the same as the target, we just do a copy.  Otherwise,
        we call floatformat_{to from}_doublest.
        * remote-nindy.c (nindy_xfer_inferior_memory):  Change param
        `write' to `should_write'.
        * utils.c (floatformat_to_long_double
        floatformat_from_long_double):  New routines that implement long
        double versions of functions in libiberty/floatformat.c.
        * config/i960/tm-i960.h (TARGET_LONG_DOUBLE_FORMAT):  Define this for
        i960 extended real (80 bit) numbers.

        dcache.
        (remote_wait): Cast second arg to strtol to correct type.
        * hppa-tdep.c (compare_unwind_entries): Change argument types to
        "const void *" to be type compatible with qsort, and then

        and/or ADD_PSYMBOL_ADDR_TO_LIST macro(s) with call to

        user-defined command sometimes leaves instream NULL and causes a
        segfault in command_loop.
