7aefdaa6ef Update the copyright notice in files ending in '.in' because the 
script change-copyright-year did not handle them.
Update the script as well.

244ccd72d3 Have perf/vg_perf handling EXTRA_REGTEST_OPTS 
Similarly to tests/vg_regtest, allow to run all perf tests with extra options.
(note: it was preferred to use the same env var name).

2bd926a725 outer/inner setup: new perf/vg_perf options to run perf tests + support translation chaining in inner. 
* perf/vg_perf:
Similarly to tests/vg_regtest, perf/vg_perf now accepts the 3 
optional arguments:
    --outer-valgrind
    --outer-tool
    --outer-args

This allows easy analysis or comparison of performance between
different Valgrind versions (e.g. using callgrind, or cachegrind/cg_diff).

* See README_DEVELOPERS for more details.

* vg_regtest modified so as to use the 'in-place' build of inner, rather
  than the installed version.

* added option --smc-check=all-non-file to vg_perf and vg_regtest 
  outer default arguments (needed when evaluating a Valgrind which does
  translation chaining).

00f539d573 Remove the --all option from vg_perf. It's useless now that there are 
tool-specific tests in massif/perf/ and memcheck/perf/.

eef723fbcc An extension of the previous commit: the vg_perf --tools option is so useful 
that I got rid of the "tools:" line in the .vg_perf files.

7a2f3512f4 Add a useful --tools option to vg_perf, which lets you override the "tools" 
line in the .vgperf files from the command line.

931e8921fd Just use the first two letters of the toolname as the abbreviation. 
Saves having to maintain a table of toolnames and abbreviations.

abc80f65ad Print native time to two places. Perhaps it would be better to adjust 
the workloads to make some of the native runs take longer.

d38a28567e Improvments to vg_perf:

  Valgrind
- don't accept --reps < 0

to time, and presents their timings in an easy-to-compare way.

49db1b68a8 First attempt at some performance tracking tools. Includes a script vg_perf 
(use "make perf" to run) that executes test programs and times their
slowdowns under various tools.  It works a lot like the vg_regtest script.
It's a bit rough around the edges -- eg. you can't currently directly
compare two different versions of Valgrind, which would be useful -- but it
is a good start.

There are currently two test programs in perf/.  More will be added as time
goes on.  This stuff will be built on so that performance changes can be
tracked over time.
