At present, libm tests for each function get built into a single
executable (for each floating point type, for each of normal / inline
/ finite-math-only functions, plus vector variants) and run together,
resulting in a single PASS or FAIL (for each of those nine variants
plus vector variants). Building this executable involves reading
over 50 MB of libm-test-*.c sources.
This patch arranges for tests of each function to be run separately
from the makefiles instead. There are 121 functions being tested for
each (type, variant pair) (actually 126, but run as 121 from the
Makefile because each of the pairs (exp10, pow10), (isfinite, finite),
(lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of
test results and so is run together), so 1089 separate tests run from
the Makefile, plus 48 vector tests on x86_64 (six functions for eight
vector variants). Each test only involves a libm-test-<func>.c file
of no more than about 4 MB, rather than all such files taking about 50
MB. With tests run separately, test summaries will indicate which
functions actually have problems (of course, those problems may just
be out-of-date libm-test-ulps files if the file hasn't been updated
for the architecture in question recently).
All the .c files for the 1089+48 tests are generated automatically
from the Makefiles. Various checked-in boilerplate .c files are
removed as no longer needed. CFLAGS definitions for the different
kinds of tests are generated using makefile iterators to apply
target-specific variable settings. libm-have-vector-test.h is no
longer needed; the list of functions to test for each vector type is
now in the sysdeps Makefile.
This should reduce the amount of boilerplate needed for float128
testing support; test-float128.h will still be needed, but not various
.c files or Makefile CFLAGS definitions. The logic for creating
dependencies on libm-test-support-*.o files should also render
<https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html>
unnecessary.
Tested for x86_64 and x86.

Continuing the process of splitting up libm tests into more reasonably
sized units, this patch splits libm-test.inc into 121 separate
libm-test-<function>.inc files, one per array of test data. (There
are 126 libm *_test functions, but five of those are for functions
that are aliases for test purposes and so share arrays of test data.)
In the present patch, the 121 files get processed separately by
gen-libm-test.pl, each using only the auto-libm-test-out-<function>
file that is relevant (/dev/null for functions not using
auto-libm-test-* at all). This effectively eliminates the
serialization on running gen-libm-test.pl. However, the resulting .c
files still all get #included together, so compiling the limited
number of libm tests using libm-test.inc may still act as a
serialization point (the compilations still all have 40 MB of code to
process). libm-test.inc doesn't actually have anything in it any more
that needs gen-libm-test.pl processing, but is left as a .inc file
that gets processed to produce a .c file, rather than being renamed,
since the intent of this patch is as an intermediate step before
libm-test.inc gets removed and tests get compiled separately for each
function being tested.
Tested for x86_64.

math/auto-libm-test-out is, at over 30 MB, by far the largest file in
the glibc source tree. This patch splits it by function, so reducing
it to auto-libm-test-out-<func> files that are all under 5 MB in size.
This is preliminary to splitting up libm-test.inc as well so that each
function's tests can also be processed separately by
gen-libm-test.pl. As a preliminary patch it doesn't actually
implement that step; rather, all the separate files get concatenated
by the Makefile to produce the monolithic auto-libm-test-out file
again as an input to gen-libm-test.pl. (The concatentation is
identical to the file in the source tree before this patch.)
Even this preliminary step, however, is of use independent of
splitting up libm-test.inc: some tests for csin and csinh have not
been moved to auto-libm-test-in because they result in
auto-libm-test-out generation taking several minutes rather than a few
seconds (all released MPC versions are very slow for certain sin /
sinh inputs; there are some old improvements in MPC mainline which
should eventually become MPC 1.1, but the complex inverse trig and
hyperbolic functions are slow even in MPC mainline and have yet to be
moved to auto-libm-test-in at all), and it seems much more reasonable
to add such inputs to auto-libm-test-in when it will only slow down
regeneration for particular functions than when it will slow down
regeneration globally.
gen-auto-libm-tests still parses the whole input file, but only
generates output for the requested function. This ensures bad syntax
in the file is always detected, and parsing the whole file is quick;
it's output generation that is comparatively slow for some functions.
Tested for x86_64.

This patch reworks how input and output files are specified for
gen-libm-test.pl.
Previously, the script had names of various inputs and outputs
hardcoded, with a -o option to specify an output directory. This
patch replaces this with all inputs and outputs being specified
explicitly as the arguments of options passed to the script. Outputs
are only generated if the relevant option is passed, and only the
processing required for the indicated outputs is done. The Makefile
is made to pass options for generating libm-test-ulps.h in a separate
invocation of gen-libm-test.pl from that generating libm-test.c.
This is all in preparation for splitting up libm-test.inc and
auto-libm-test-out and running tests separately for each function,
when gen-libm-test.pl will be run separately for each function to
generate the .c file but only once to generate libm-test-ulps.h (and
those runs will be able to be in parallel).
Tested for x86_64. The generated libm-test.c and libm-test-ulps.h are
identical before and after the patch. Also tested the "make
regen-ulps" case.

As recently discussed
<https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it
doesn't seem particularly useful for libm-test-ulps files to contain
huge amounts of data on ulps for individual tests; just the global
maximum observed ulps for each function, together with the
verification of exceptions, errno and special results such as
infinities and NaNs for each test, suffices to verify that a
function's behavior on the given test inputs is within the expected
accuracy. Removing this data reduces source tree churn caused by
updates to these files when libm tests are added, and reduces the
frequency with which testsuite additions actually need libm-test-ulps
changes at all.
Accordingly, this patch removes that data, so that individual tests
get checked against the global bounds for the given function and only
generate an error if those are exceeded. Tested x86_64 (including
verifying that if an ulps value is artificially reduced, the tests do
indeed fail as they should and "make regen-ulps" generates the
expected changes).

The wiki "Regeneration" page has this to say about update ULPs.
"The libm-test-ulps files are semiautomatically updated. To
update an ulps baseline, run each of the failing tests (test-float,
test-double, etc.) with -u; this will generate a file called ULPs;
concatenate each of those files with the existing libm-test-ulps
file, after removing any entries for particularly huge numbers of
ulps that you do not want to mark as expected. Then run
gen-libm-test.pl -n -u FILE where FILE is the concatenated file
produced in the previous step. This generates a file called
NewUlps which is the new sorted version of libm-test-ulps."
The same information is listed in math/README.libm-test, and is a
lot of manual work that you often want to run over-and-over again
while working on a particular test.
The `regen-ulps' convenience target does this automatically for
developers.
We strictly assume the source tree is readonly and add a
new --output-dir option to libm-test.inc to allow for writing
out ULPs to $(objpfx).
When run the new target does the following:
* Starts with the baseline ULPs file.
* Runs each of the libm math tests with -u.
* Adds new changes seen with -u to the baseline.
* Sorts and prepares the test output with gen-libm-test.pl.
* Leaves math/NewUlps in your build tree to copy to your source
tree, cleanup, and checkin.
The math test documentation in math/README.libm-test is updated
document the new Makefile target.
