Commentary wording now refers to tasks (i.e., threads) rather than processes. This makes it somewhat easier to justify adding two kinds of counters together. After researching what "load average" has meant over time, we have what seems like a reasonable implementation, modulo Windows differences to Linux. The best resource I found is: https://www.brendangregg.com/blog/2017-08-08/linux-load-averages.html At end of load_init(), obtain and discard the first measure of the counters to deal with the first call always returning error, no data. Follow this with a specific short delay so the next measure actually has data to report. At least one older version of Windows, i.e. Win10 Pro 21H1, has a different name/location for the '% Processor Time' counter and is missing the 'Processor Queue Length' counter entirely. Code is changed to support both possible locations of the former and treat the missing latter as always reporting 0.0. A release note is added for 3.5.6.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
