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be out-of-date libm-test-ulps files if the file hasn't been updated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.

libmvec tests involve calling INIT_ARCH_EXT during initialization then
CHECK_ARCH_EXT before testing each function to see if the processor
being used for testing supports the required instruction set
extensions.
After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT
call is in libm-test-support.c, built only once per floating-point
type. Now, in fact all definitions of this macro are empty, but given
that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are
conditional on REQUIRE_* macros defined in particular vector tests, it
seems more correct for the INIT_ARCH_EXT call to go instead in
libm-test-driver.c which gets built separately with those REQUIRE_*
macros properly defined. This patch moves the call there.
Tested for x86_64 and x86.

libm-test-driver.c contains various functions used in the course of
libm testing, which are built as part of each test using this
machinery.
Currently, these functions get built for three tests for each type
(e.g. test-float, test-ifloat, test-float-finite), plus the vector
function tests. All these tests are huge and thus slow to build; the
output of gen-libm-test.pl totals around 40 MB across all functions.
To make the individual tests built from the Makefile smaller, it makes
sense to split these tests up so the tests for each function are built
separately (thus, three tests for each (function, type) pair, plus
vector tests built only for functions that actually have vector
versions). This improves parallelism and means that if tests fail,
the summary of failed tests makes it more obvious where the problem
might be without needing to look in the .out files to see which
functions' tests failed (though architecture maintainers still need to
keep libm-test-ulps up to date to avoid spurious failures of little
interest).
Simply including libm-test-driver.c as-is in such individual-function
tests does not work because of unused static check_* functions (those
functions only being used for the types of the outputs of the function
under test). It also means the common code gets built over 1000 times
instead of nine (plus vector tests). To avoid that issue, this patch
splits out the bulk of the libm-test-driver.c code into a separate
file libm-test-support.c (with a few functions made non-static). That
separate file is built only once for each floating-point type (so at
present three times, or twice on architectures with long double =
double). Definitions needed in both libm-test-support.c and
libm-test-driver.c go in libm-test-support.h (it's possible some of
those are in fact only needed in one of the two files).
libm-test-driver.c keeps definitions of a limited number of variables
used to configure how libm-test-support.c behaves, various macros and
structures needed by individual-function tests, and the main function.
This move is also consistent in spirit with the move away from
test-skeleton.c having all the test support code, to a small
support/test-driver.c included in individual tests with most of the
code built separately.

Splitting libm tests by function will mean about a thousand such tests
built separately instead of the present nine (plus vector variants).
When this is done, it's desirable to avoid needing to build all the
test infrastructure so many times. Also, simply including
libm-test-driver.c as-is into per-function tests doesn't actually
work, because the various check_* functions are not used by all tests
and so generate errors for unused static functions.
Although some pieces of infrastructure depend on the type being tested
while others don't, building once per type seems the simplest
approach. This patch makes changes to libm-test-driver.c in
preparation for that. Various cases where functions directly use
macros such as TEST_ERRNO (that may vary depending on things other
than the type under test) are changed to use variables initialized
using those macros, while most of the code in main is moved out to
functions libm_test_init and libm_test_fini.
The idea is that all the functions in libm-test-driver.c will be moved
out in a subsequent patch to be built once per type (and be no longer
static when they are used from per-function tests), while
libm-test-driver.c remains containing definitions of various variables
(no longer static, of course, because they'll be used in the per-type
code) and the main function. Declarations / macros relevant to both
the once-per-type code and the per-function tests will go in a shared
header.
Tested for x86_64.

Various files using the libm-test infrastructure define a TEST_MSG
macro with an informal description of the tests being run.
This patch moves this macro to libm-test-driver.c (the definition
depending on other macros already defined), so files specific to
(type, choice of whether to test inline functions or finite-math-only
functions, vector length) no longer need to define it. This is in
preparation for replacing files such as test-float.c with per-function
test-float-<func>.c etc. automatically generated in the build
directory when tests are run.
Tested for x86_64.

libm-test.inc contains both test infrastructure and tests of
individual functions.
This patch moves the infrastructure to a separate file
libm-test-driver.c. This is in preparation for splitting the tests of
individual functions into separate source files, which will be
processed individually by gen-libm-test.pl (so e.g. libm-test-acos.inc
and auto-libm-test-out-acos will be processed by gen-libm-test.pl to
produce libm-test-acos.c, and files such as test-double-acos.c will be
generated by the Makefile to include appropriate headers,
libm-test-driver.c and libm-test-acos.c so tests of each function get
run separately).
It is no doubt possible to split things up further, so that functions
not depending on the type being tested only get compiled once and most
of those depending on the type being tested get compiled once per type
(rather than separately for variants such as inline / no-inline, and
separately for each function being tested after that split), but this
rearrangement as-is seems a useful incremental step towards splitting
these tests by function.
