0c09737883 Add SPARC --disable-multi-arch builds to build-many-glibcs.py.
While working on SPARC changes to use libm_alias_* I noticed that the
non-multi-arch sparc32/sparcv9/fpu/s_fabs.S was missing compat symbol
support for fabsl.  This clearly shows inadequate test coverage, so
this patch adds SPARC --disable-multi-arch builds to
build-many-glibcs.py (the 32-bit one fails testing until that bug is
fixed, the 64-bit one passes testing).

	* scripts/build-many-glibcs.py (Context.add_all_configs): Add
	SPARC --disable-multi-arch glibc variants.

34bb10aabf Use libm_alias_float for x86_64.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes x86_64 libm function implementations use
libm_alias_float to define function aliases, or libm_alias_float_other
where the main name is defined with versioned_symbol.

Tested with the glibc testsuite for x86_64, and tested with
build-many-glibcs.py for all its x86_64 configurations that installed
stripped shared libraries are unchanged by the patch.

aa1142c593 Use libm_alias_float for ia64.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes ia64 libm function implementations use
libm_alias_float to define function aliases.  The same approach is
followed as with the corresponding long double and double patches: the
ia64-specific macros are left unchanged, with calls to
libm_alias_float_other being added in most cases and libm_alias_float
itself being used in only a few places.

Tested with build-many-glibcs.py for ia64-linux-gnu that installed
stripped shared libraries are unchanged by the patch.

8da25eec0a Collation fix: make forward accent sorting the default [BZ #17750]
[BZ #17750]
	* Makefile: add fr_CA.UTF-8 to test-input and LOCALES.
	* localedata/fr_CA.UTF-8.in: New file with test data for backward
	accents sorting.
	* localedata/fr_FR.UTF-8.in: Fix test data for forward accents

	* localedata/locales/iso14651_t1_common: Use “ifdef DIACRIT_FORWARD”
	instead of “ifdef DIACRIT_BACKWARD”.

The only locale which currently needs backward accents sorting is fr_CA.
Therefore, forward accents sorting should be the default.

Before this patch, backwards accent sorting was the default and all
locales except fr_CA had to use

    define DIACRIT_FORWARD

before

    copy "iso14651_t1"

Most locales didn’t do that and thus got the inappropriate backwards accents sorting
by accident. Now only the fr_CA locale needs to use

    define DIACRIT_BACKWARD

before

    copy "iso14651_t1"

a55430cb0e sparc: Assume VIS3 support
This patch assumes VIS3 support by binutils, which is supported since
version 2.22.  This leads to some code simplification, mostly on
multiarch build where there is only one variant instead of previously
two (whether binutils supports VIS3 instructions or not).

For multiarch files where HAVE_AS_VIS3_SUPPORT was checked and
the default implementation was built with a different name, a new
file with (implementation with -generic appended) is added.

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

Continuing the preparation for additional _FloatN / _FloatNx function

libm_alias_double to define function aliases.  The same approach is
followed as with the corresponding long double patch: the
ia64-specific macros are left unchanged, with calls to
libm_alias_double_other being added in most cases and
libm_alias_double itself being used in only a few places.

8d81ce0c6d Properly compute offsets of note descriptor and next note [BZ #22370]
A note header has 3 4-bytes fields, followed by note name and note
descriptor.  According to gABI, in a note entry, the note name field,
not note name size, is padded for the note descriptor.  And the note
descriptor field, not note descriptor size, is padded for the next
note entry.  Notes are aligned to 4 bytes in 32-bit objects and 8 bytes
in 64-bit objects.

For all GNU notes, the name is "GNU" which is 4 bytes.  They have the
same format in the first 16 bytes in both 32-bit and 64-bit objects.
They differ by note descriptor size and note type.  So far, .note.ABI-tag
and .note.gnu.build-id notes are always aligned to 4 bytes.  The exsting
codes compute the note size by aligning the note name size and note
descriptor size to 4 bytes.  It happens to produce the same value as
the actual note size by luck since the name size is 4 and offset of the
note descriptor is 16.  But it will produce the wrong size when note
alignment is 8 bytes in 64-bit objects.

This patch defines ELF_NOTE_DESC_OFFSET and ELF_NOTE_NEXT_OFFSET to
properly compute offsets of note descriptor and next note.  It uses
alignment of PT_NOTE segment to support both 4-byte and 8-byte note
alignments in 64-bit objects.  To handle PT_NOTE segments with
incorrect alignment, which may lead to an infinite loop, if segment
alignment is less than 4, we treate alignment as 4 bytes since some
note segments have 0 or 1 byte alignment.

When executing bench-math the benchmark output is invalid with this

    the regexes: '^[_a-zA-Z0-9]*$¹ or Invalid benchmark output: Additional

The error was seen when running the test:
workload-spec2006.wrf, 'stack=1024,guard=1' and 'stack=1024,guard=2'.
The problem is that the current regex's do not accept the hyphen, dot, equal

b4c645c2f5 posix: Make tst-getaddrinfo[45] xtests due to DNS dependency [BZ #20826]
These tests need a working Internet connection with DNS.

We have additional coverage of getaddrinfo through the resolv tests, so
the loss of default test coverage seems acceptable.

f433d0b3bb Use libm_alias_float for alpha.
Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes alpha libm function implementations use
libm_alias_float macros to define function aliases.  In the case of
the ABI compatibility for complex functions, libm_alias_float_other is
used, with the cfloat_versions macro adjusted to take a function name
argument without the trailing 'f' to facilitate this, and
cfloat_versions dealing with calling libm_alias_float_other (except
for clog10f, which doesn't use that macro because of the complexity
associated with __clog10f also being exported).

Tested with build-many-glibcs.py for alpha-linux-gnu that installed
stripped shared libraries are unchanged by the patch.

a23aa5b727 Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x
function aliases on platforms with _Float64x support.  (It so happens
the set of such platforms is exactly the same as the set of platforms
with _Float128 support, although on x86_64, x86 and ia32 the _Float64x
format is Intel extended rather than binary128.)  The API provided
corresponds exactly to that provided for _Float128, mostly coming from
TS 18661-3.  As these functions always alias those for another type
(long double, _Float128 or both), __* function names are not provided,
as in other cases of alias types.

Given the preparation done in previous patches, this one just enables
the feature via Makeconfig and bits/floatn.h, adds symbol versions,
and updates documentation and ABI baselines.  The symbol versions are
present unconditionally as GLIBC_2.27 in the relevant Versions files,
as it's OK for those to specify versions for functions that may not be
present in some configurations; no additional complexity is needed
unless in future some configuration gains support for this type that
didn't have such support in 2.27.  The Makeconfig additions for ia64
and x86 aren't strictly needed, as those configurations also get
float64x-alias-fcts definitions from
sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given
that _Float64x is not _Float128 for those configurations.

A libm-test-ulps update for x86 is included.  This is because
bits/mathinline.h does not have _Float64x support added and for two
functions the use of out-of-line functions results in increased ulps
(ifloat64x shares ulps with ildouble / ifloat128 as appropriate).
Given that we'd like generally to eliminate bits/mathinline.h
optimizations, preferring to have such optimizations in GCC instead,
it seems reasonable not to add such support there for new types.  GCC
support for _FloatN / _FloatNx built-in functions is limited, but has
been improved in GCC 8, and at some point I hope the full set of libm
built-in functions in GCC, and other optimizations with
per-floating-type aspects, will be enabled for all _FloatN / _FloatNx
types.

Tested for x86_64 and x86, and with build-many-glibcs.py, with both
GCC 6 and GCC 7.

6e70d156c7 Support _Float64x in libm_alias macros.
This patch adds support for libm_alias_ldouble and libm_alias_float128
to create *f64x function aliases when appropriate.

Making such aliases work for functions defined in assembly sources
requires adding some semicolons after weak_alias calls in alias macro
definitions.  For C, semicolons are already present in the macros
called when required, but a GNU C extension allows excess semicolons
at file scope in a source file (and glibc already uses this), so it is
OK to have extra semicolons present in the macro definitions.  For
assembly sources, making multiple alias macro calls from a single
macro expansion means there are no newlines between the calls, so an
explicit separator is needed.  If hppa were to have .S sources in
libm, a more complicated approach would be needed that used
ASM_LINE_SEP when building assembly sources but not for C, but right
now there are no such sources so just using a semicolon (as already
present unconditionally in some such macro expansions) suffices.

9596fc69b1 Make min_of_type_ macros function-like.
math_private.h uses __MATH_TG in defining the min_of_type macro used
within libm, with min_of_type_<suffix> macros for each type.  This
runs into problems with __MATH_TG expansions used with additional
_FloatN and _FloatNx type support, because those can end up
macro-expanding the FUNC argument to __MATH_TG before it gets
concatenated with a suffix - meaning that min_of_type_ can't
simultaneously be the macro name for double, and a prefix to other
macro names, since the latter case requires such premature macro
expansion not to occur.  (This is not a problem for the uses of
__MATH_TG in installed headers because FUNC there is a function name
in the implementation namespace, and the suffixes themselves don't get
macro-expanded.)

This patch fixes the problem by making min_of_type_<suffix> macros
function-like, so no macro expansion occurs when min_of_type_ is
expanded on its own as a macro argument, only later when followed by
() after expansion.

Tested for x86_64, including in conjunction with _Float64x support
patches.

01e659e711 Fix gen-tgmath-tests.py for _Float64, _Float64x testing.
math/gen-tgmath-tests.py was missing a create_type argument when
creating the internal types for combinations of long double with
_Float64 and _Float64x, so resulting in output that did not compile
when glibc support for those types was enabled.  This patch adds the
missing argument so that the tests properly compile in that case.

c45d78aac4 posix: Fix generic p{read,write}v buffer allocation (BZ#22457)
As described in BZ#22457 an interpose malloc can free an invalid
