        * core.c (get_src_info): Cast arg 7 of bfd_find_nearest_line
        to proper type of "unsigned int *".

Fri Jun 16 15:29:36 1995  Ken Raeburn  <[email protected]>

        * configure.in: Use changequote around use of [].

Mon Jun 12 12:14:52 1995  J.T. Conklin  <[email protected]>

        * Makefile.in (distclean, realclean): Remove config.cache and
          config.log.

Wed May 17 17:56:53 1995  J.T. Conklin  <[email protected]>

        * Makefile.in (Makefile): Added config.status to dependency list.
          (config.status): New target.
          (SHELL): New definition.

Tue Apr 25 21:11:12 1995  Ken Raeburn  <[email protected]>

        * Makefile.in (install): Depend on "all".

Thu Apr 20 17:29:07 1995  Ken Raeburn  <[email protected]>

        * Makefile.in: Change all references to MY_MACHINE to MY_TARGET,
        to match configure script.

Wed Apr 19 11:19:37 1995  J.T. Conklin  <[email protected]>

        * gen-c-prog.awk: Changed reference to "make-c-prog.awk" in
          comment emitted by this script to gen-c-prog.awk.

        * Makefile.in, configure.in: Converted to use autoconf.
        * configure: New file, generated with autoconf 2.3.
        * config/{mt-alpha, mt-dummy, mt-i386, mt-ns532, mt-sparc,
          mt-tahoe, mt-vax}: Removed.

Mon Mar 13 21:44:24 1995  Ken Raeburn  <[email protected]>

        * __bb_exit_func.c: New file, from David Mosberger-Tang.

        Thu Feb  9 16:56:07 1995  David Mosberger-Tang  <[email protected]>

        * All *.c: More cleanup towards GNU format.

        * gmon_out.h (struct gmon_hist_hdr, struct gmon_cg_arc_record): 
        replaced sizeof (bfd_vma) by size (char*) because Ken tells me
        that bfd_vma is only guaranteed to be at least as big as a pointer.

        (GMON_Record_tag): added explicit enumeration values to ensure
        compatibility across compilers.

        * gmon_io.c (get_vma, put_vma): replaced sizeof(bfd_vma) by
        sizeof(char*).

Tue Feb  7 17:24:12 1995  Ken Raeburn  <[email protected]>

        * All *.c and *.h files: Ran "indent -gnu".  Cleaned up a couple
        of constructs GNU indent couldn't handle.  Block comments not yet
        rewritten in GNU format.

        * gprof.c (VERSION): Changed to 2.6, to get in sync for next
        binutils release.

Sun Feb  5 16:19:46 1995  David Mosberger-Tang  <[email protected]>

        * symtab.c (symtab_finalize): ensure globals symbols really
        are favored over static ones---even if their name looks less
        preferable; this is important for HP-UX; for example, there
        is a static label Ltext_something that aliases the global
        symbol _start

        * hist.c (hist_print): auto-scaling is now in effect for FSF-style
        output only; also, auto-scaling is now performed based on
        per-call, rather than total execution time, which is what it was
        meant to be.

        * gprof.h (File_Format): new type.

        * gprof.c (VERSION): upped to 2.7---seems to be completely out of
        sync with Cygnus version numbers though...

        (long_options): renamed --gmon-info to --file-info, --width added,
        renamed --old-file-format to --file-format
        (main): dito; also added support to read prof files, but as
        mon_out_read() is not implemented, it's #ifdef'd out for now

        (usage): update to reflect new options.

        * gmon_io.c: replaced "old_file_format" by more general
        "file_format" option

        * gmon.h (struct raw_phdr): fixed declaration for OSF/1.

        * core.c (core_sym_class): added back check for __gnu_compiled and
        ___gnu_compiled for the benefit of systems without
        bfd_find_nearest_line() support

        (get_src_info): now the libbfd is fixed, invoke bfd_find_nearest_line()
        with section-relative addresses

        (core_create_function_syms): get_src_info() calls are currently
        enabled for OSF/1 only.  It appears to work allright for SunOS
        4.1.x as well, but on SPARCs it gets painfully slow with the
        current implementation of aout_32_find_nearest_line();
        unfortunately, this means that static functions will not have their
        filename printed in the call-graph function index; line-level
        profiling should still work, but requires some patience

        * cg_print.c (cg_print_index): sanitised printing of index when
        using FSF-style output; in particular, output width is now controlled
        via option --width and the function tries hard to keep columns
        aligned even in the presence of (occasional) long names

        * NOTES: a first shot at updating the documentation.

Wed Feb  1 19:07:44 1995  David Mosberger-Tang  <[email protected]>

        * core.c (core_create_function_syms): fixed computation of min_vma
        and max_vma.

        * *.c: removed rcsid.

Tue Jan 31 16:18:18 1995  Ken Raeburn  <[email protected]>

        * Lots of changes from David Mosberger-Tang:

        Tue Oct 25 19:20:14 1994  David Mosberger-Tang  <[email protected]>

        * gprof.c (main): put parentheses around & within &&.

        * basic_blocks.c (bb_read_rec): print warning message (once) when
        ignoring basic-block execution counts.

        * source.c (source_file_lookup_name): corrected second argument to
        strcmp().

        * hist.c (print_header): merged Fri Oct 21 18:58:02 1994 change by
        Ken Raeburn <[email protected]> from binutils-2.5.1.

        * gmon_io.c (gmon_out_read): the output stule STYLE_GMON_INFO is now
        supported both for old and new (versioned) gmon.out files.  Old
        files are identified as version 0.

        * gmon.h (struct raw_arc): count field is now sizeof(long) bytes
        long (instead of 4) because that is what OSF/1 v3.0 uses.

        * core.c: minor fixes and debugging info changes.

        Sun Sep 11 18:47:47 1994  David Mosberger-Tang  ([email protected])

        * core.c (core_init): if .text cannot be found, try $CODE$ (the
        name of the text-section under HP-UX).

        * hist.c (hist_assign_samples): fixed off-by-one bug: highpc
        points one past the last sampling bin, so hist_scale should be
        computed as "hist_scale /= hist_num_bins", not "hist_scale /=
        hist_num_bins - 1".

        * gmon_io.c, hist.c, hist.h: renamed hist_num_samples to
        hist_num_bins.

        * configure.in: added alpha-*-*) for per-target config.

        * alpha.c, alpha.h: created.

        * gprof.c (default_excluded_list): <locore>, <hicore> added.

        * core.c (core_create_function_syms, core_create_line_syms):
        explicitly keep two sentinels "<locore>" and "<hicore>" that catch
        all addresses outside the text-space.  Thus, sym_lookup(&symtab,
        addr) continues to guarantee not to return 0 on any address.  It
        also avoids incorrectly crediting the first/last symbol in the
        text-space.

        * core.c (core_create_line_syms): always create function symbols
        first, then merge in line symbols; this is so that if parts of the
        program were compiled without -g, function-level symbols are
        available still.

        * utils.c (print_name_only): support for print_path added.

        * symtab.c (cmp_addr): also use is_func flag in comparison.
        (symtab_finalize): return immediately when table empty; now
        more careful about getting rid of the right duplicate symbol.

        * sparc.c (find_call): many fixes---this function was rather
        botched in binutils-2.4 already; it should work again.

        * source.c (source_file_lookup_path): PATH is now strdup'ed (it is
        not good to rely on get_src_info() to return distinct string
        pointers).

        * search_list.c (search_list_append): added cast for xmalloc().

        * hist.c: added explicit initialization to some of the global
        variables; fixed SItab (scales were off by a factor of 10).

        * hist.h: include of bfd.h added.

        * gprof.c, gprof.h (print_path): added.

        * gprof.h (MAX): fixed.

        * gmon_out.h: renamed gmon_time_hist_hdr to gmon_hist_hdr.

        * gmon_io.c: added some casts to (long) so we can always print as %lx

        * core.c (core_get_text_space): fixed to make it work.

        * cg_print.c (cg_print_index): added support for print_path option.

        * cg_dfn.h (cg_dfn): wrap prototype in PARAMS().

        * call_graph.c, gmon_io.c, hist.c: avoid taking address of array
        as some compilers complain (e.g., DEC's OSF/1 compiler)

        * basic_blocks.c, gmon_io.c, hist.c, source.c, sym_ids.c,
        symtab.c: calls to memset() had 2nd and 3rd args reversed.

        Sat Sep 10 21:53:13 1994  David Mosberger-Tang  ([email protected])

        * gprof.c: added "_mcount" to default_excluded_list.
        (main): if output_style==0 and there is either a histogram or a
        call-graph, always generate flat and call-graph, no matter what
        line_granularity is set to.

        * source.c (source_file_lookup_name): if searching for sf->name
        fails, try again with filename obtained after stripping off any
        partial path from sf->name.

        * gprof.h (SRCDEBUG): added.

        * search_list.c (search_list_append): directories were added in wrong
        order.

        * reimplemented selection mechanism from ground up; it is now possible
        to accurately control what gets included/excluded in each of the
        output styles;  a "symbol-specification" (spec) is the basic means
        to select a set of symbols; a spec has the syntax:

          spec == (FILENAME:(FUNCNAME|LINE_NUM) | NAME).
          arc == spec/spec.

        any of the terminal symbols can be empty, in which case they
        match anything (wildcards).  NAME is interpreted as a FILENAME
        if it contains a dot (e.g., foo.c), as LINE_NUM if it starts
        with a digit, and as FUNCNAME otherwise.

        For example, to get a call-graph display that ignores arcs
        from foo() to bar(), you'd say "--no-graph=foo/bar"; to
        show only arcs into bar() (no matter what the caller),
        you'd say "--graph=/bar"; and to get a call-graph without
        any arc info, you'd say "--graph=/";  similarly, to
        get a flat profile without mcount, you'd say "--no-flat=mcount"
        and to get a flat profile that shows includes all functions
        you'd say "--flat=""" (i.e., an empty spec)

        * hist.c (hist_print): top_time wasn't initialized to 0.0.

        Fri Sep  9 01:10:21 1994  David Mosberger-Tang  ([email protected])

        * gmon_out.h: all headers now declared in terms of characters
          to avoid getting into trouble with different compilers introducing
          different amount of padding; the code already accessed the fields
          through bfd functions, so that didn't have to change.

        * hist.c (hist_read_rec, hist_write_rec): added support for
          collection pc histograms measuring quantities other than time;
          the histogram header now includes a field that specifies the
          dimension of the quantity measured by the histogram bins
          (normally, this is "seconds", but other meaningful dimensions
           include such things as "I-cache misses", "instruction issue stalls"
           etc.); there is also a field to specify a one-character
          abbreviation for the dimension; in the case of time, this would
          be 's'; in most other cases it probably would be '1' (not a physical
          dimension).

        Thu Sep  8 16:05:08 1994  David Mosberger-Tang  ([email protected])

        * gprof.c, gmon_io.[ch]: BSD_COMPATIBLE is gone and new_file_version
          has become old_file_version; gmon_io.c now always supports old-style
          gmon.out files; it first tries to read gmon.out as a new version
          file, if that fails, it tries to read it in the old format;
          although not very likely, it is possible for gprof to mistake an
          old-style file as a new one (the first 4 bytes would have to
          be "gmon"---including the trailing '\0'); in that case, it is
          necessary to specify --old-file-version

        * gprof.h: removed dependency on SYSV; the code now always uses
          strrchr(), memset(), and memcpy() and does not include either
          of string.h or strings.h; this should make gprof compile on
          any (Unix) system without configuration (per suggestion of
          [email protected])

        * gprof.c (usage): fixed location of --new-file-format option.

        * cg_arcs.c (propagate_flags): fixed typo in declaration.

        * flat_bl.m: removed formfeed at end of file; the form-feed
          is now printed cg_print.c only when necessary.

        * major rewrite of gprof---too many changes to mention all of
          them.  new features:

        + -l now requests profiling at the line level (as opposed
          to function level); in this mode, gprof creates a "symbol"
          (aka name-list entry) for each line of source code, instead
           of one per function)

        + support for a new gmon.out file format; the new format 
          consists of a header with a magic and a version number,
          followed by a sequence of profile data; profile data
          can any of: (a) PC histogram, (b) call-graph arcs, or
          (c) basic-block execution counts; the version number makes
          it possible to extend gmon.out in a backwards compatible
          fashion

        + support for tcov style annotated output: if the gmon.out file
          contains basic-block execution counts, the user can request
          the generation of annotated source files, much like Sun's
          tcov used to do

        + long options

        + new scheme to suppress symbols that aren't function names
          (e.g., avoids mistaking a goto label as a function)

        + reorganized source code to make it more managable; as a
          side effect, gprof now compiles cleanly with "gcc -Wall"

        Thu Sep  1 15:46:49 1994  David Mosberger-Tang  ([email protected])

        * gprof.c (funcsymbol): bfd_find_nearest_line() is now used as a
        final cross-check to determine whether a static symbol should be
        considered as a function-name.

        Fri Aug  5 19:32:36 1994  David Mosberger-Tang  ([email protected])

        * gmon_io.c (gmon_out_read): recognize "-" as the filename for
        stdin; this is useful if you wanna keep gmon.out files compressed;
        this way you can "gzcat" the compressed file into gprof.

        * gprof.c: flag_min_count now initialized with 1 instead of 0.

        * basic_blocks.c (bb_annotate_source): added support for creating
        .tcov files when option flag_annotate_make_files is TRUE.
        (annotate_with_count): all counts less than the minimum count
        specified by -m are now annotated with hash-marks.

        * gprof.c (main): -A is now followed by a string of option chars.

        * basic_blocks.c (annotate_with_count): replaced b->count with
        cnt.

        * source.c: flag_annotate_source replaced by source_lock_map.

        * source.h: source_lock_map added.

        * gprof.c (main): new command-line syntax: -S simply specifies
        which source-files user is interested in; -A requests annotated
        source files and -AA requests that all lines in a source file
        are annotated.

        Thu Aug  4 23:27:03 1994  David Mosberger-Tang  ([email protected])

        * basic_blocks.c (PATH_MAX): if undefined, define as 1024.

        * sparc.c, i386.c, tahoe.c, vax.c: added include of "time_hist.h"
        so s_lowpc etc. get declared.

        * arcs.h (doarcs): created.

        * arcs.c: reordered static functions such that they get defined
        before use.

        * gprof.c (main): added options:
           -A: request annotation of all source lines (with -S)
           -m: minimum execution count (with default basic-block display)
           -N: force new file format (only if BSD_COMPATIBLE is defined)
           -S: annotate source file
           -t: set table length (with -S)

        * Makefile (OBJS): added basic_blocks.o call_graph.o gmon_io.o
        source.o time_hist.o

        Fri Jul  1 15:23:50 1994  David Mosberger-Tang  ([email protected])

        * gprof.c (asgnsamples): computation of "pcl" and "pch" depended
        on the fact being able to store a long in a double without loss of
        precision; this does not hold on machines with 64 bit longs and 64
        bit doubles.

Fri Oct 21 18:58:02 1994  Ken Raeburn  <[email protected]>

        * printgprof.c (flatprofheader): Always set totime to 1.0 if not
        greater than 0.0.  Suggested by Harold Assink
        <[email protected]>.

Fri Sep 23 15:06:45 1994  Ken Raeburn  <[email protected]>

        * printgprof.c (printprof): Use free, not cfree.
        (printgprof, printindex): Ditto.

Thu Sep  1 10:40:45 1994  Jeff Law  ([email protected])

        * gprof.h (kfromlist, ktolist, flist, Flist, elist, Elist): Make
        decls extern to keep native HP compiler quiet.

Tue Aug 30 11:12:13 1994  Ian Lance Taylor  ([email protected])

        * gprof.c (funcsymbol): Ignore ___gnu_compiled as well as
        __gnu_compiled, for the benefit of systems which add a leading
        underscore.

Wed Aug 24 12:49:13 1994  Ian Lance Taylor  ([email protected])

        * configure.in: Change i386-*-* to i[345]86-*-*.

Sun Jul 10 00:35:31 1994  Ian Dall  ([email protected])

        * ns532.c, ns532.h: New Files. ns532 support.

        * config/mt-ns532: New File. ns532 support.

        * gprof.c: user register int i instead of defaulting the int.
        Allows compilation with -Dregister= for debugging.

        * configure.in: Add ns532 support.

Thu Jun 23 11:22:41 1994  Jeff Law  ([email protected])

        * Makefile.in (gprof): Depend on $(LIBS).

Fri May 27 12:24:57 1994  Ken Raeburn  ([email protected])

        From binutils-2.4 release:

        Wed May 11 22:32:00 1994  DJ Delorie ([email protected])

        * configure.bat: [new] build makefile from makefile.in (dos)
        * hertz.c: allow static HERTZ (msdos needs it)
        * gprof.c: allow target to select "r" or "rb" for fopen
        * gprof.c: ignore __gnu_compiled symbols
        * i386.h: dfine FOPEN_RB to "rb" for dos.

Tue May 17 15:30:22 1994  E. Michael Smith ([email protected])

        * Makefile.in (.m.c:):  Added .SUFFIXES : .m 
        so flat_bl.c would make from flat_bl.m file.

Thu May  5 19:23:24 1994  Ken Raeburn  ([email protected])

        * Makefile.in (install-info): Check for gprof.info in build dir,
        fall back to srcdir.  Depend on it.

        * gprof.h (TRUE, FALSE): Always use undef before defining them.

Mon Apr  4 23:47:30 1994  Jeffrey A. Law  ([email protected])

        * Makefile.in (MY_MACHINE): Renamed from MACHINE to avoid losing
        makes (osf1) in which the value of MACHINE can not be changed.
        * config/*.mt: Changed appropriately.

Wed Mar 30 16:12:40 1994  Ian Lance Taylor  ([email protected])

        * gprof.c (getsymtab): Change nosyms to long.  Rename
        get_symtab_upper_bound to bfd_get_symtab_upper_bound.  Check for
        errors from bfd_get_symtab_upper_bound and
        bfd_canonicalize_symtab.

Tue Mar 22 10:50:52 1994  Jeffrey A. Law  ([email protected])

        * gprof.c (funcsymbol): Use bfd_get_symbol_info instead of
        bfd_decode_symclass.

Sun Mar 20 15:40:21 1994  Jeffrey A. Law  ([email protected])

Fri Oct  9 11:25:41 1992  Mark Eichin  ([email protected])

        * gprof.1: updated SYNOPSIS to match actual behavior.

Mon Oct  5 17:50:16 1992  Per Bothner  ([email protected])

        * gen-c-prog.awk:  New awk script, lightly changed from
        previously deleted make-c-prog.awk.  Converts a text file
        to a c function that prints that text.
        * flat_bl.m, fsf_callg_bl.m, bsd_callg_bl.m:  New files.
        Inputs to gen-c-prog.awk, containing text describing
        gprof output.
        * blurbs.c:  Removed.  Use *_bl.c instead.
        * Makefile.in: Use gen-cprog.awk to generate *_bl.c files
        from *_bl.m files.  Also, improve *clean rules.
        * printgprof.c (printgprof):  Usw new function names from *_bl.c.
        

Sun Aug 30 19:54:53 1992  Per Bothner  ([email protected])

        * gprof.h, gprof.c, printfgprof.c:  Add support for two
        output styles:  The default is similar to the old FSF gprof,
        while -T sets the variable bsd_style_output, which causes
        output matching Berkeley's gprof.  The biggest differences
        are that with the FSF style output, the flat profile comes
        before the call graph; numbers come before explanations;
        and there is less gratuitous white space.
        * gprof.h, gprof.c, printfgprof.c:  New discard_underscores
        variable causes discarding of initial underscores when
        printing symbol names.  It is set unless there is a "main"
        symbol (without an underscore).
        * printfgprof.c:  New function printnameonly(), called
        by printname().  It handles stripping of initial '_',
        as well as C++ name-demangling.
        * gprof.callg, gprof.flat, make-c-prog.awk:  Removed.
        It is just as convenient to edit blurbs.c directly.
        * Makefile.in:  Removed rule for making blurbs.c.
        * blurbs.c:  This is now a true source file (as opposed
        to being generated from gprof.callg and gprof.flat).
        Change style to use one long string literal, instead of
        one literal per output line.  Add FSF-style blurb for call graph.

Wed Aug 19 14:36:39 1992  Ian Lance Taylor  ([email protected])

        * Makefile.in: always create installation directories.

Wed Aug 12 15:14:14 1992  Mark Eichin  ([email protected])

        * Makefile.in: change ${MACHINE} to $(MACHINE).

Sun Jul 19 17:34:01 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

        * Makefile.in:  removed installation of the now useless
        call.{flag,callg} files.  

        * gprof.1: now uses the standard man macros instead of the new BSD
        mandoc macros. 

Sun Jul 12 19:06:00 1992  John Gilmore  (gnu at cygnus.com)

        * configure.in:  Remove host section, expand target section.
        * config/mt-{tahoe,vax}:  Add, to match existing support files.
        * config/tmake-*:  Remove leftover crud.

        * blurbs.c:  New file, created from gprof.flat and gprof.callg by
        * make-c-prog.awk:  which processes text files into C programs.
        * printgprof.c (flatprofheader, gprofheader):  Call new functions
        to print blurbs.
        (printblurb):  Remove.
        * Makefile.in:  Infrastructure to build blurbs.
        * pathnames.h:  has been removed.  Gprof now has no filename
        dependencies in it.
        * gprof.c:  Lint.

Sat Jul 11 18:07:21 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

        * Makefile.in: define man1dir and install the man page

Fri Jul 10 21:14:08 1992  david d `zoo' zuhn ([email protected])

Thu Jun  4 11:34:02 1992  Mark Eichin  (eichin at cygnus.com)

        * lookup.c: fixed fencepost in nllookup and added dbg_nllookup for
        help in debugging the problem (with -DDEBUG)
        * gprof.c: symbol values are now real values, don't add the vma
        anymore. (done for solaris; should verify this on other platforms)
        * ChangeLog: created.
