This patch converts the implementation of exp2l in math/e_exp2l.c into
a template in math/e_exp2_template.c, then adjusts Makefile to use
this template for long double (the implementations for float and
double in sysdeps have higher precedence and are not used). This
template can also be used for float128, thus reducing the amount of
duplicated code that gets added when adding support the new type.
Tested for powerpc64le and s390x.
* math/Makefile (libm-calls): Move e_exp2F to gen-libm-calls.
(gen-libm-calls): Add e_exp2F to use the template.
* math/e_exp2l.c: Rename to math/e_exp2_template.c.

The classification macros: finite, fpclassify, iseqsig, isinf, isnan,
issignaling, and signbit are defined by ISO C11 and declared in
mathcalls.h for each of the floating-point types: float, double, and
long double.
TS 18661-3 does not mention these macros for float128, however support
for them must be present when _Float128 is present. This is true,
even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is
false. Other function declarations in mathcalls.h, on the other hand,
depend on __STDC_WANT_IEC_60559_TYPES_EXT__.
This patch splits the helper functions (__finite, __fpclassify,
__iseqsig, __isinf, __isnan, __issignaling, and __signbit) from
mathcalls.h, so that these helper functions can be declared for
_Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false.
Tested for powerpc64le, s390x, and x86_64.
* include/bits/mathcalls-helper-functions.h: New file.

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.

Several wrappers for IEEE functions use _LIB_VERSION / matherr /
__kernel_standard functionality, which we want to obsolete. New

the new float128 wrappers.

This patch moves tests of catan and catanh with finite inputs (other
than the divide-by-zero cases producing an exact infinity) to using
the auto-libm-test machinery. Each of auto-libm-test-out-catan and
auto-libm-test-out-catanh takes about three seconds to generate on my
system (so in fact it wasn't necessary after all to defer the move to
auto-libm-test-* until the output files were split up by function).

Both libm-compat-calls and libm-compat-calls-auto list the functions
that must be built for the types float, double, and long double, but
not for other floating-point types that get added to libm. Besides
that, the use of libm-compat-calls-ldouble-yes to select if
w_lgamma_compatl and k_standardl should be built for long-double (in
libm-compat-calls) has the same effect of the use of type-foreach
(in libm-compat-calls-auto).
This patch merges the contents of libm-compat-calls into
libm-compat-calls-auto, then renames the latter to libm-compat-calls.
Tested for powerpc64le, s390, and x86_64.

The libm tests of inline functions undefine __NO_MATH_INLINES (from
math-CPPFLAGS) in test-math-inline.h, but __LIBC_INTERNAL_MATH_INLINES
via -U options in the makefile.
This is an odd inconsistency between the handling of the two macros.
It also depends on the ordering (in compilation commands) of the
various variables providing compiler options (which I think is why
it's using CPPFLAGS-*.c instead of CFLAGS-*.c).
This patch moves the undefine to test-math-inline.h, so improving
consistency and eliminating the dependency on the order in which
variables go in the compilation commands. The CPPFLAGS-*.c variables
are renamed to CFLAGS-*.c, matching those for the non-inline libm
function tests.
By moving the -U option to the header file, this should ensure that
ordering issues don't arise with a subsequent move of the options to
these tests to target-specific CFLAGS += ... variable settings (for
when tests for each function are build separately and so compilation
options need setting for many more makefile targets, for which
target-specific variable settings seem to be the most convenient form
to generate with iterators).
Tested for x86_64.

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.
