This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00197.html>, makes
testsuite runs generate an overall summary of test results.
A new script merge-test-results.sh deals both with collecting results
within a directory to a file with all the results from that directory,
and collecting the results from subdirectories into a single overall
file (there's not much in common between the two modes of operation of
the script, but it seemed silly to have two separate scripts for
this). Within a directory, missing results produce UNRESOLVED lines;
at top level, missing results for a whole directory produce an ERROR
line (since toplevel can't identify what the specific missing tests
are in this case).
Note that this does not change the rules for when "make" considers
there has been an error, or terminates, so unexpected failures will
still cause make to terminate, or, with -k, mean the commands for
"tests" don't get run because of failure of a dependency.
Tested x86_64, including that the summary does in fact reflect all the
tests with .test-result files.

This patch is a revised and updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>.
In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.
Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that. Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing, and in future we would like to be able to mark
tests as UNSUPPORTED if they are disabled for a particular
configuration (rather than simply having them missing from the list of
tests as at present). Such handling of tests that were not run or did
not record results requires an explicit enumeration of tests.
For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration. Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets. This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.
Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before. We previously
discussed the question of where to include Rules; see the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.
It was necessary to avoid an indirection through the check-abi target
and get the check-abi-* targets for individual libraries into the
tests-special variable. The intl/ test $(objpfx)tst-gettext.out,
previously built only because of dependencies from other tests, was
also added to tests-special for the same reason.
The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out. If a future change causes tests to be named
consistently with a .out suffix, this can be changed to include just
the path relative to $(objpfx), without .out.
Tested x86_64, including that the same set of files is generated in
the build directory by a build and testsuite run both before and after
the patch (except for changes to the
elf/tst-null-argv.debug.out.<number> file name), and a build with
run-built-tests=no to verify there aren't any more obvious instances
of the issue Marcus Shawcroft reported with a previous version in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>.

This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00193.html>, starts
the process of generating explicit PASS or FAIL status for individual
glibc tests. It's based on Tomas Dohnalek's patch
<https://sourceware.org/ml/libc-alpha/2012-10/msg00278.html>, but is
deliberately more minimal: it doesn't try to cover any tests outside
of $(tests) / $(xtests) (that's for a later patch), nor does it put
the result together in an overall summary file (again, a later patch):
it just generates the .test-result files.
Thus, this patch keeps the overall logic for when a testsuite run
finishes completely unchanged: a test failing will terminate the run.
I think we *should* move to a more conventional approach where plain
"make check" does not terminate for an individual test failure, unless
e.g. you say "make stop-on-test-failure=y check", but that sort of
policy change is best done as a separate patch once the infrastructure
is in place to generate summary files for completed test runs (which
will entirely consist of PASS and XFAIL lines if the testsuite run
reaches the point of generating them, until such a policy change is
made).
Tested x86_64.

run-via-rtld-prefix checks whether the program to be run is a static
test and skips if it is. This is fine, except that it assumes that
the program to be run is the second $^, which is true only for tests.
This change creates an rtld-prefix, which is simply the dynamic linker
prefix with the necessary arguments and uses that in the non-test
targets.
Write output from the currently running benchmark into a temporary
file and move files around only once the current run is complete.
That way we don't lose data from the last two runs due to an
incomplete run.
This allows us to define custom functions in C code files and
benchmark scenarios rather than just functions. The main current use
of this is to separate the slow and fast path benchmarks for math
functions.
