The recent difftime changes introduced localplt test failures on nios2
and sparc32, two configurations where some soft-fp functions are
defined in / exported from libc.so, and where the difftime changes
affected the particular set of floating-point operations used in
libc.so. This patch adds those functions to localplt.data, alongside
other such functions already there. (In the sparc32 case, and more
generally on any platform where long double is a software
floating-point type, it would probably be more efficient to avoid
using long double at all in difftime, but that's a pre-existing
issue.)
Tested with build-many-glibcs.py for its nios2 and sparcv9
configurations.
[BZ #24023]
* sysdeps/unix/sysv/linux/nios2/localplt.data: Allow __floatundidf
PLT reference in libc.so.
* sysdeps/unix/sysv/linux/sparc/sparc32/localplt.data: Allow
_Q_lltoq and _Q_qtod PLT references in libc.so.
After previous cleanups, the only code in the x86 bits/mathinline.h
that is relevant with current compilers is the inline of
__ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES
(i.e. for when libm itself is being built).
This inline is something that does belong in glibc not GCC, since
__ieee754_atan2l is a purely internal function name. This patch moves
that inline to a new sysdeps/x86/fpu/math_private.h, removing the
bits/mathinline.h header.
Note that previously the inline was only for non-SSE 32-bit x86. That
condition does not make sense, however, for a long double function; if
it's not inlined, exactly the same x87 instruction will end up getting
used by the out-of-line function, for both 32-bit and 64-bit. So that
condition is not retained in the new version.
Tested for x86_64 and x86. As expected, installed stripped shared
libraries are unchanged for 32-bit x86, but installed stripped libm.so
is changed for x86_64 because calls to __ieee754_atan2l start being
inlined where previously they were out of line calls. (The same
change to start inlining the function would presumably also apply for
32-bit built with -mfpmath=sse, but that's not a configuration I've
tested.)
* sysdeps/x86/fpu/math_private.h: New file.
* sysdeps/x86/fpu/bits/mathinline.h: Remove.
Continuing the removal of bits/mathinline.h inlines that would better
be done by the compiler, this patch removes x86 inlines for sinh, cosh
and tanh functions (inlines only previously present for fast-math,
non-SSE 32-bit x86). I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such
inlines as an optimization in GCC.
I believe the only remaining part of the x86 bits/mathinline.h that
does anything useful with current compilers after this patch is the
__LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to
remove the whole header and move that inline to a sysdeps
math_private.h header in a subsequent patch.
Tested for x86_64 and x86.
* sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline
definition.
(cosh): Likewise.
(tanh): Likewise.
Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY,
AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE,
AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when
LD_SHOW_AUXV=1.
AT_L*_CACHESIZE is printed as decimal and represent the number of
bytes of the cache.
AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size
and its associativity.
Example output from a POWER8:
AT_L1I_CACHESIZE: 32768
AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L1D_CACHESIZE: 65536
AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L2_CACHESIZE: 524288
AT_L2_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L3_CACHESIZE: 8388608
AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative
Some of the new types are longer than the previous ones, requiring to
increase the indentation in order to keep the values aligned.
* elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE,
AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY,

AT_L3_CACHEGEOMETRY. Fix indentation when printing the other
fields.
(_dl_show_auxv): Give a special treatment to
AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY
and AT_L3_CACHEGEOMETRY.
* sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function.
(_dl_procinfo): Fix indentation when printing AT_HWCAP and
AT_HWCAP2. Add support for AT_L1I_CACHEGEOMETRY,
AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.

Alpha rt_sigaction syscall uses a slight different kernel ABI than
generic one:
arch/alpha/kernel/signal.c
90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act,
91 struct sigaction __user *, oact,
92 size_t, sigsetsize, void __user *, restorer)
Similar as sparc, the syscall expects a restorer function. However
different than sparc, alpha defines the restorer as the 5th argument
(sparc defines as the 4th).
This patch removes the arch-specific alpha sigaction implementation,
adapt the Linux generic one to different restore placements (through
STUB macro), and make alpha use the Linux generic kernel_sigaction
definition.
Checked on alpha-linux-gnu and x86_64-linux-gnu (for sanity).

Commit b4a5d26d88 (linux: Consolidate sigaction implementation) added
a wrong kernel_sigaction definition for m68k, meant for __NR_sigaction
instead of __NR_rt_sigaction as used on generic Linux sigaction
implementation. This patch fixes it by using the Linux generic
definition meant for the RT kernel ABI.
Checked the signal tests on emulated m68-linux-gnu (Aranym). It fixes
the faulty signal/tst-sigaction and man works as expected.

kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment
"However, SH is lame, and still does not have a 64-bit inode field.".
The macro is, in fact, defined to 0 by Alpha as well as SH. The Alpha
case is, however, trivially useless: none of the files that test
__ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel
support for stat64 syscalls, with a 64-bit st_ino field, in Linux
2.6.4; the define to 0 for Alpha in glibc predates that).
The SH kernel gained support for a 64-bit st_ino in struct stat64 in
commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64()
syscall."), which is in Linux 2.6.22 and later. So the redefinition
of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of
the files testing it do so immediately after a stat64-family syscall
has been used, which will always have set the 64-bit st_ino correctly
(in addition to the 32-bit __st_ino), while the relevant code
__xstat32_conv executes only after such a syscall in the function
calling __xstat32_conv.
Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it.
Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv
renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases
around it identical, so that conditional is also removed.
Tested compilation with build-many-glibcs.py for its Alpha and SH
configurations; also ran the glibc testsuite for x86_64 and x86.

The ifunc macros s390_vx_libc* are no longer used and

The ifunc handling for stpncpy is adjusted in order to omit ifunc
variants if those will never be used as the minimum architecture level
already supports newer CPUs by default.
Glibc internal calls will then also use the "newer" ifunc variant.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove stpncpy variants.
* sysdeps/s390/Makefile (sysdep_routines): Add stpncpy variants.
