Many m68k libm functions use their own system to share code between
different types and functions, involving defining macros before
including code for another function (for example, s_atan.c also acts
as a template that can define other functions).
Thes files serving as templates generate function aliases directly
with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c. To be
prepared to generate _Float32, _Float64 and _Float32x function
aliases, this needs changing so that the libm_alias_* macros get used
instead. As the macro to use varies depending on the type, that would
mean additional macros to define in several different places to get
the appropriate alias-generation macro used in each case.
Rather than adding to the m68k-specific mechanisms, this patch
converts the functions in question to use something closer to the
math/ type-generic template mechanism. After this patch, these
functions have m68k-specific templates such as s_atan_template.c, but
those templates use all the same macros as in the math/ templates,
such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias. There is no
automatic generation of the files such as s_atan.c that include the
appropriate math-type-macros-*.h header and the template file (the
existing automatic generation logic is only applicable for the fixed
set of templates listed in math/ - and sysdeps sources always override
files generated that way), so those files are still checked in, but
they are all the obvious two-line files (with one additional
definition in the case of the expm1 implementations), rather than
making e.g. s_atan.c special.
Functions are only converted where they should have aliases for
_FloatN / _FloatNx types. Those m68k functions that do not generate
public names (those that only generate __ieee754_*, with wrappers
generating the public names, and classification functions that only
exist once per format not once per type so don't get aliases) are
unchanged. However, log1p (public names generated by wrapper) and
significand (not provided for new types so no new aliases needed)
needed changing because they previously included the atan
implementations. Now, s_significand.c is the main implementation for
functions with that prototype and using the old implementation
approach, while log1p includes it in place of atan.
Any further cleanups in this area (which preserve the proper set of
functions getting aliases defined by libm_alias_float and
libm_alias_double) are of course welcome, just not needed for the
goals of this patch.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

Since this file is no longer checked in, update-copyrights no longer

* scripts/update-copyrights: Do not handle intl/plural.c

There is a subtle non-determinism when building glibc.
This depends on whether the glibc is built using the distibuted
file intl/plural.c or built using the generated file intl/plural.c.
These two files (intl/plural.c generated vs. distributed) are slightly
different, hence we may end up with slightly different libraries.
Originally, having "bison" installed was optional. So if "bison" was
not present, we always built libraries with the distributed plural.c.
If bison was installed, we *** may have *** replaced the distributed
file plural.c with a new plural.c generated from plural.y. if the
timestamps triggered this rule:
plural.c plural.y
$(BISON) $(BISONFLAGS) $@ $^
Given that timestamps are not preserved in GIT repositories, the above
rule is not reliable without explicitly touching plural.c or plural.y.
In other words, the rule may or may not have fired.
In summary: there are two distinct sources of non-determinism:
1. Having "bison" installed or not
2. Having "bison" installed but timestamps poorly defined.
This patch fixes this by requiring "bison" being installed
and by always generating intl/plural.c from intl/plural.y.
(This is achieved by simply removing checked-in intl/plural.c)

Most m68k libm functions share code via sources for one function
including those for another function or type, in a way that will
require significant changes to create function aliases in a way
friendly to adding _FloatN / _FloatNx aliases.
The llrint function implementations, however, use a conventional
separate implementation for each floating-point type. Thus preparing
them for _FloatN / _FloatNx aliases is just a matter of changing them
to include the appropriate headers and use the appropriate macros,
which this patch does. The llrintl changes aren't strictly required,
since m68k long double does not meet the criteria for a _FloatN /
_FloatNx type, but are included anyway to keep consistency between the
implementations for the three types.

Some m68k libm functions have their own templates replacing the

These currently define function aliases directly using weak_alias. In
preparation for additional _FloatN / _FloatNx function aliases, this
patch changes them to use declare_mgen_alias for creating aliases
instead.

To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement
Technology (CET) in setjmp/longjmp, we need to save shadow stack
pointer in jmp_buf. The __saved_mask field in jmp_buf has type
of __sigset_t. On Linux, __sigset_t is defined as
#define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int)))
typedef struct
{
unsigned long int __val[_SIGSET_NWORDS];
} __sigset_t;
which is much bigger than expected by the __sigprocmask system call,
which has
typedef struct {
unsigned long sig[_NSIG_WORDS];
} sigset_t;
For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf
to add paddings for shadow stack pointer. As long as the new __sigset_t
is not smaller than sigset_t expected by the __sigprocmask system call,
it should work correctly.
This patch adds an internal header file, <setjmpP.h>, to define
__jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a
space to store shadow stack pointer. It verifies __jmp_buf_sigset_t has
the suitable size for the __sigprocmask system call. A run-time test,
tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t
is sufficient. If its size is too small, the test fails with
rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc
0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address)
rt_sigprocmask(SIG_SETMASK, strace: umoven: short read (4 < 8) @0x7fa8aa28effc
0x7fa8aa28effc, NULL, 8) = -1 EFAULT (Bad address)
rt_sigprocmask(SIG_SETMASK, NULL, 0x7fa8aa28effc, 8) = -1 EFAULT (Bad address)

When the per-thread cache is enabled, __libc_malloc uses request2size (which
does not perform an overflow check) to calculate the chunk size from the
requested allocation size. This leads to an integer overflow causing malloc
to incorrectly return the last successfully allocated block when called with
a very large size argument (close to SIZE_MAX).
This commit uses checked_request2size instead, removing the overflow.
The sparc32/sparcv9/fpu/multiarch implementations of llrint / llrintf
have aliases lllrint / lllrintf. No such function is exported from or
used in libm and these aliases should not be there; I expect they
arose accidentally in the course of converting a 64-bit implementation
(where lrint and llrint can be aliases) to a 32-bit llrint
implementation. This patch removes those spurious aliases.
Tested (compilation only) with build-many-glibcs.py for

The --disable-multi-arch case of sparcv9 libm is missing a fabsl
compat symbol for when long double had the same ABI as double. This
patch adds the missing compat symbol to this implementation. As my
fix for other instances of this missing compat symbol postdates the
last release, I'm considering this as being part of bug 22229 that was
missing from my previous fix rather than as a separate issue, and so
as not needing a new bug report in Bugzilla.
Tested (compilation only) with build-many-glibcs.py for
sparcv9-linux-gnu --disable-multi-arch.

* sysdeps/sparc/sparc32/sparcv9/fpu/s_fabs.S: Include
<math_ldbl_opt.h>.
(fabsl): Define as compat symbol at version GLIBC_2_0 for libm.
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

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"

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.

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.
