Mon Mar 13 21:44:24 1995 Ken Raeburn <raeburn@cujo.cygnus.com>
* __bb_exit_func.c: New file, from David Mosberger-Tang.
Thu Feb 9 16:56:07 1995 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
* 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 <raeburn@cujo.cygnus.com>
* 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 <davidm@piston.cs.arizona.edu>
* 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): sanitized 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 <davidm@piston.cs.arizona.edu>
* 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 <raeburn@cujo.cygnus.com>
* Lots of changes from David Mosberger-Tang:
Tue Oct 25 19:20:14 1994 David Mosberger-Tang <davidm@piston.cs.arizona.edu>
* 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 <raeburn@cujo.cygnus.com> 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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
raeburn@cygnus.com)
* 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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 (davidm@piston.cs.arizona.edu)
* 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 <raeburn@cujo.cygnus.com>
* printgprof.c (flatprofheader): Always set totime to 1.0 if not
greater than 0.0. Suggested by Harold Assink
<carlo@sg.tn.tudelft.nl>.

decls extern to keep native HP compiler quiet.
Tue Aug 30 11:12:13 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

__gnu_compiled, for the benefit of systems which add a leading
underscore.

* configure.in: Change i386-*-* to i[345]86-*-*.
Sun Jul 10 00:35:31 1994 Ian Dall (dall@hfrd.dsto.gov.au)

From binutils-2.4 release:
Wed May 11 22:32:00 1994 DJ Delorie (dj@ctron.com)
* 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 (ems@cygnus.com)
* 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 (raeburn@cujo.cygnus.com)
* 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 (law@snake.cs.utah.edu)
* 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 (ian@tweedledumb.cygnus.com)
* gprof.c (getsymtab): Change nosyms to long. Rename

when the -v option is used
Tue Jul 6 10:11:56 1993 Steve Chamberlain (sac@phydeaux.cygnus.com)
* Makefile.in: Install correctly.
Thu Jun 24 14:43:22 1993 David J. Mackenzie (djm@thepub.cygnus.com)
* gprof.c (main): Get whoami from argv, instead of hardcoding.
Use it in usage message. Split usage message to fit in 80 cols.

* Makefile.in (install): should not depend on install-info
Mon Apr 26 12:37:46 1993 Ian Lance Taylor (ian@cygnus.com)

Tue Apr 13 16:14:03 1993 Per Bothner (bothner@cygnus.com)
* M Makefile.in: Add -g to CFLAGS.
Ads LDFLAGS and use in place of CFLAGS where appropriate.
* configure.in: Make a sysdep.hlink in the same way other
bfd-based directories do.
* gprof.h (UNIT): Replace non-standard 'u_short' by 'unsigned
short'.

Tue Mar 23 00:03:11 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
* Makefile.in: add installcheck target
Sat Feb 27 18:17:10 1993 Per Bothner (bothner@rtl.cygnus.com)

Wed Feb 3 13:55:33 1993 Jeffrey Osier (jeffrey@fowanton.cygnus.com)
* Makefile.in: created info, install-info, dvi
Wed Jan 6 00:58:09 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
* Makefile.in: fix install rule for $(PROG)
Fri Oct 9 11:25:41 1992 Mark Eichin (eichin@cygnus.com)
* gprof.1: updated SYNOPSIS to match actual behavior.
Mon Oct 5 17:50:16 1992 Per Bothner (bothner@cygnus.com)
* 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 (bothner@rtl.cygnus.com)
* 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 (ian@cygnus.com)
* Makefile.in: always create installation directories.
Wed Aug 12 15:14:14 1992 Mark Eichin (eichin@cygnus.com)
* 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 (zoo@cygnus.com)
* Makefile.in: added dummy info and install-info targets
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.
