abd383584b Add narrowing square root functions 
This patch adds the narrowing square root functions from TS 18661-1 /
TS 18661-3 / C2X to glibc's libm: fsqrt, fsqrtl, dsqrtl, f32sqrtf64,
f32sqrtf32x, f32xsqrtf64 for all configurations; f32sqrtf64x,
f32sqrtf128, f64sqrtf64x, f64sqrtf128, f32xsqrtf64x, f32xsqrtf128,
f64xsqrtf128 for configurations with _Float64x and _Float128;
__f32sqrtieee128 and __f64sqrtieee128 aliases in the powerpc64le case
(for calls to fsqrtl and dsqrtl when long double is IEEE binary128).
Corresponding tgmath.h macro support is also added.

The changes are mostly similar to those for the other narrowing
functions previously added, so the description of those generally
applies to this patch as well.  However, the not-actually-narrowing
cases (where the two types involved in the function have the same
floating-point format) are aliased to sqrt, sqrtl or sqrtf128 rather
than needing a separately built not-actually-narrowing function such
as was needed for add / sub / mul / div.  Thus, there is no
__nldbl_dsqrtl name for ldbl-opt because no such name was needed
(whereas the other functions needed such a name since the only other
name for that entry point was e.g. f32xaddf64, not reserved by TS
18661-1); the headers are made to arrange for sqrt to be called in
that case instead.

The DIAG_* calls in sysdeps/ieee754/soft-fp/s_dsqrtl.c are because
they were observed to be needed in GCC 7 testing of
riscv32-linux-gnu-rv32imac-ilp32.  The other sysdeps/ieee754/soft-fp/
files added didn't need such DIAG_* in any configuration I tested with
build-many-glibcs.py, but if they do turn out to be needed in more
files with some other configuration / GCC version, they can always be
added there.

I reused the same test inputs in auto-libm-test-in as for
non-narrowing sqrt rather than adding extra or separate inputs for
narrowing sqrt.  The tests in libm-test-narrow-sqrt.inc also follow
those for non-narrowing sqrt.

Tested as followed: natively with the full glibc testsuite for x86_64
(GCC 11, 7, 6) and x86 (GCC 11); with build-many-glibcs.py with GCC
11, 7 and 6; cross testing of math/ tests for powerpc64le, powerpc32
hard float, mips64 (all three ABIs, both hard and soft float).  The
different GCC versions are to cover the different cases in tgmath.h
and tgmath.h tests properly (GCC 6 has _Float* only as typedefs in
glibc headers, GCC 7 has proper _Float* support, GCC 8 adds
__builtin_tgmath).

8cc1e39a36 Drop nan-pseudo-number.h usage from tests 
Make the tests use TEST_COND_intel96 to decide on whether to build the
unnormal tests instead of the macro in nan-pseudo-number.h and then
drop the header inclusion.  This unbreaks test runs on all
architectures that do not have ldbl-96.

Also drop the HANDLE_PSEUDO_NUMBERS macro since it is not used
anywhere.

2b778ceb40 Update copyright dates with scripts/update-copyrights 
I used these shell commands:

../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")

and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...

1c15464ca0 math: Remove inline math tests 
With mathinline removal there is no need to keep building and testing
inline math tests.

The gen-libm-tests.py support to generate ULP_I_* is removed and all
libm-test-ulps files are updated to longer have the
i{float,double,ldouble} entries.  The support for no-test-inline is
also removed from both gen-auto-libm-tests and the
auto-libm-test-out-* were regenerated.

Checked on x86_64-linux-gnu and i686-linux-gnu.

42760d7646 Make totalorder and totalordermag functions take pointer arguments. 
The resolution of C floating-point Clarification Request 25
<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is
that the totalorder and totalordermag functions should take pointer
arguments, and this has been adopted in C2X (with const added; note
that the integration of this change into C2X is present in the C
standard git repository but postdates the most recent public PDF
draft).

This patch updates glibc accordingly.  As a defect resolution, the API
is changed unconditionally rather than supporting any sort of TS
18661-1 mode for compilation with the old version of the API.  There
are compat symbols for existing binaries that pass floating-point
arguments directly.  As a consequence of changing to pointer
arguments, there are no longer type-generic macros in tgmath.h for
these functions.

Because of the fairly complicated logic for creating libm function
aliases and determining the set of aliases to create in a given glibc
configuration, rather than duplicating all that in individual source
files to create the versioned and compat symbols, the source files for
the various versions of totalorder functions are set up to redefine
weak_alias before using libm_alias_* macros to create the symbols
required.  In turn, this requires creating a separate alias for each
symbol version pointing to the same implementation (see binutils bug
<https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is
done automatically using __COUNTER__.  (As I noted in
<https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might
well make sense for glibc's symbol versioning macros to do that alias
creation with __COUNTER__ themselves, which would somewhat simplify
the logic in the totalorder source files.)

It is of course desirable to test the compat symbols.  I did this with
the generic libm-test machinery, but didn't wish to duplicate the
actual tables of test inputs and outputs, and thought it risky to
attempt to have a single object file refer to both default and compat
versions of the same function in order to test them together.  Thus, I
created libm-test-compat_totalorder.inc and
libm-test-compat_totalordermag.inc which include the generated .c
files (with the processed version of those tables of inputs) from the
non-compat tests, and added appropriate dependencies.  I think this
provides sufficient test coverage for the compat symbols without also
needing to make the special ldbl-96 and ldbl-128ibm tests (of
peculiarities relating to the representations of those formats that
can't be covered in the generic tests) run for the compat symbols.

Tests of compat symbols need to be internal tests, meaning _ISOMAC is
not defined.  Making some libm-test tests into internal tests showed
up two other issues.  GCC diagnoses duplicate macro definitions of
__STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added
an appropriate conditional and filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue.
On ia64, include/setjmp.h ends up getting included indirectly from
libm-symbols.h, resulting in conflicting definitions of the STR macro
(also defined in libm-test-driver.c); I renamed the macros in
include/setjmp.h.  (It's arguable that we should have common internal
headers used everywhere for stringizing and concatenation macros.)

2813e41e90 Replace gen-libm-test.pl with gen-libm-test.py. 
Following the recent discussion of using Python instead of Perl and
Awk for glibc build / test, this patch replaces gen-libm-test.pl with
a new gen-libm-test.py script.  This script should work with all
Python versions supported by glibc (tested by hand with Python 2.7,
tested in the build system with Python 3.5; configure prefers Python 3
if available).

This script is designed to give identical output to gen-libm-test.pl
for ease of verification of the change, except for generated comments
referring to .py instead of .pl.  (That is, identical for actual
inputs passed to the script, not necessarily for all possible input;
for example, this version more precisely follows the C standard syntax
for floating-point constants when deciding when to add LIT macro
calls.)  In one place a comment notes that the generation of
NON_FINITE flags is replicating a bug in the Perl script to assist in
such comparisons (with the expectation that this bug can then be
separately fixed in the Python script later).

Tested for x86_64, including comparison of generated files (and hand
testing of the case of generating a sorted libm-test-ulps file, which
isn't covered by normal "make check").

I'd expect to follow this up by extending the new script to produce
the ulps tables for the manual as well (replacing
manual/libm-err-tab.pl, so that then we just have one ulps file
parser) - at which point the manual build would depend on both Perl
and Python (eliminating the Perl dependency would require someone to
rewrite summary.pl in Python, and that would only eliminate the
*direct* Perl dependency; current makeinfo is written in Perl so there
would still be an indirect dependency).

I think install.texi is more or less equally out-of-date regarding
Perl and Python uses before and after this patch, so I don't think
this patch depends on my patch
<https://sourceware.org/ml/libc-alpha/2018-08/msg00133.html> to update
install.texi regarding such uses (pending review).

3195833899 Handle narrowing function sNaN test disabling based on argument format. 
Testing narrowing functions for x86_64 with GCC 6 showed up a further
testsuite fix needed: there is no _Float128 sNaN support before GCC 7
on x86_64 / x86, and the existing tests of SNAN_TESTS only checked it
for the return type, not for the argument type.  This patch fixes the
code to check SNAN_TESTS (ARG_FLOAT) as well (in a variable set in
libm-test-driver.c, since libm-test-support.c is compiled only once
for each choice of FLOAT).

Tested for x86_64 and x86 with GCC 6 in conjunction with the main
patch adding narrowing add functions.

	* math/libm-test-support.h (snan_tests_arg): New declaration.

8e554659ad Add test infrastructure for narrowing libm functions. 
This patch continues preparations for adding TS 18661-1 narrowing libm
functions by adding the required testsuite infrastructure to test such
functions through the libm-test infrastructure.

That infrastructure is based around testing for a single type, FLOAT.
For the narrowing functions, FLOAT, the "main" type for testing, is
the function return type; the argument type is ARG_FLOAT.  This is
consistent with how the code built once for each type,
libm-test-support.c, depends on FLOAT for such things as calculating
ulps errors in results but can already handle different argument types
(pointers, integers, long double for nexttoward).

Makefile machinery is added to handle building tests for all pairs of
types for which there are narrowing functions (as with non-narrowing
functions, aliases are tested just the same as the functions they
alias).  gen-auto-libm-tests gains a --narrow option for building
outputs for narrowing functions (so narrowing sqrt and fma will share
the same inputs as non-narrowing, but gen-auto-libm-tests will be run
with and without that option to generate different output files).  In
the narrowing case, the auto-libm-test-out-narrow-* files include
annotations for each test about what properties ARG_FLOAT must have to
be able to represent all the inputs for that test; those annotations
result in calls to the TEST_COND_arg_fmt macro.

gen-libm-test.pl has some minor updates to handle narrowing tests (for
example, arguments in such tests must be surrounded by ARG_LIT calls
instead of LIT calls).  Various new macros are added to the C test
support code (for example, sNaN initializers need to be properly
typed, so arg_snan_value is added; other such arg_* macros are added
as it seems cleanest to do so, though some are not strictly required).
Special-casing of the ibm128 format to allow for its limitations is
adjusted to handle it as the argument format as well as as the result
format; thus, the tests of the new functions allow nonzero ulps only
in the case where ibm128 is the argument format, as otherwise the
functions correspond to fully-defined IEEE operations.  The ulps in
question appear as e.g. 'Function: "add_ldouble"' in libm-test-ulps
(with 1ulp errors then listed for double and float for that function
in powerpc); no support is added to generate corresponding faddl /
daddl ulps listings in the ulps table in the manual.

For the previous patch, I noted the need to avoid spurious macro
expansions of identifiers such as "add".  A test test-narrow-macros.c
is added to verify such macro expansions are successfully avoided, and
there is also a -mlong-double-64 version of that test for ldbl-opt.
This test is set up to cover the full set of relevant identifiers from
the start rather than adding functions one at a time as each function
group is added.

Tested for x86_64 (this patch in isolation, as well as testing for
various configurations in conjunction with the actual addition of
"add" functions).

92061bb033 Run libm tests separately for each function. 
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.

b4e4172da6 Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver. 
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.

	* math/libm-test-support.h: Do not include <math-tests-arch.h>
	here.

3b2f60328e Build most libm-test support code once per type. 
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.

dcd4cd5756 Refactor some code in libm-test-driver.c. 
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.

a622c2db55 Move libm-test TEST_MSG definitions to libm-test-driver.c. 
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.

5a68e857bf Move non-function-specific parts of libm-test.inc to separate file. 
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.
