Tue May 28 11:14:58 1996  Tom Tromey  <tromey@creche.cygnus.com>

        * configure: Regenerated.
        * aclocal.m4 (CY_AC_PATH_TCLH): Don't use AC_TRY_RUN.
        (CY_AC_PATH_TKH): Don't use AC_TRY_RUN.

Sun May 26 14:14:49 1996  Fred Fish  <fnf@cygnus.com>

        Changes from: David Mosberger-Tang  <davidm@azstarnet.com>

        * 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.
        * configure: Rebuild

        * config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro.
        (SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto.
        (DYNAMIC_SIGTRAMP_OFFSET): Ditto.
        (SIGCONTEXT_ADDR): Ditto.
        (FRAME_PAST_SIGTRAMP_FRAME): Ditto.

        * config/alpha/alpha-linux.mh: New file.
        * config/alpha/alpha-linux.mt: Ditto.
        * config/alpha/nm-linux.h: Ditto.
        * config/alpha/tm-alphalinux.h: Ditto.
        * config/alpha/xm-alphalinux.h: Ditto.
        * config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h.
        * config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to
        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>

        when in H8/300H mode.  Get the return pointer's address correctly
        for the H8/300H.  Handle H8/300H prolouge code sequences.

        * symfile.c (generic_load): Print the starting address
        of the file just loaded.

Thu May 23 12:09:52 1996  Stan Shebs  <shebs@andros.cygnus.com>

        handling zero's, denorms or NaNs.

        FLOATFORMAT_TO/FROM_DOUBLEST macros.
        * config/i960/tm-nindy960.h:  Undefine
        REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW, and

        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.

        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

        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.

        * objfiles.c (add_to_objfile_sections): Cast second arg of obstack_grow
        call to correct type (char *).

        * somsolib.c (som_solib_create_inferior_hook): Add a declaration
        for external find_unwind_entry function (from hppa-tdep.c).
        * remote-pa.c (remote_write_bytes, remote_read_bytes): Change
        type of second arg to "char *" to be type compatible with
        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

        ADD_PSYMBOL_ADDR_TO_LIST): Remove.  Real world tests show no
        performance improvements by inlining via complicated macros and
