Until we update the recommended versions of autoconf/automake, files
should be regenerated with automake-1.15.1 and autoconf-2.69. That's
not because we think those versions are golden, and newer versions are
bad. It's simply because maintainers want to be able to update
configury files without trouble, and if someone regenerates files with
automake-1.16.5 then --enable-maintainer-mode builds will hit errors:
checking that generated files are newer than configure... configure.ac:26: error: version mismatch. This is Automake 1.15.1,
configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE
configure.ac:26: comes from Automake 1.16.5. You should recreate
configure.ac:26: aclocal.m4 with aclocal and run automake again.
WARNING: 'automake-1.15' is probably too old.
Correcting this requires regenerating the files by hand.
This patch enables the first support for the "gprofng display html" command.
This command works for C/C++ applications on x86_64. Using one or more gprofng
experiment directories as input, a new directory with html files is created.
Through the index.html file in this directory, the performance results may be
viewed in a browser.

The help message from 'gprofng collect app -h', in
the section on <rate> == <interval>, had a dangling
reference to a non-existent manpage. Provide basic
info, including reasons for caution.
The HTML and PDF formats are described in the gprofng tutorial (info
topic "Other Document Formats"). In addition, describe them in the
README because: they are important; they are easily searchable; and the
README is primarily oriented to the person who is installing gprofng,
who may differ from the person who follows a user tutorial.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)
Regenerate all affected configure scripts.
* libtool.m4 (LT_PATH_NM): Handle user-specified NM with
options, including options containing paths.
