Move multiple definitions of the nested function b64_from_24bit into a
single function __b64_from_24bit.

* sysdeps/sparc/fpu/libm-test-ulps: Update.

* sysdeps/ieee754/flt-32/e_j1f.c (__ieee754_y1f): Force computations
to occur in round to nearest mode when |x| >= 2.0

Forgotten in ca3cfa40c16ef34c74951a07a57cfcbcd58898b1
where the error branch was moved from PSEUDO_RET.

* sysdeps/x86_64/link-defines.sym (BND_SIZE): Replace __int128
with __int128_t.

The current malloc_info xml output only has information about
allocations on the heap. Display information about number of mappings
and total mmapped size to this to complete the picture.

In several cases we've had asm routines rely on syscalls not clobbering
call-clobbered registers, and that's now deemed ABI. So take advantage
of this in the INLINE_SYSCALL path as well.
Shrinks libc.so by about 1k.

One push instead of N; use stp/ldp to halve the insns.
|
|
Use cbz instead of cmp+b.eq.
|
|
Fold nocancel and error handling paths.

Delay the use of stat/fstat until stat data is required. When the
kernel returns ST_VALID, stat data is not used by __internal_statvfs.

The current code for handling concurrent resolution says that the
ABI for _dl_tlsdesc_resolve_hold is the same as that of
_dl_tlsdesc_lazy_resolver. However _dl_tlsdesc_resolve_hold is
called from the trampoline directly rather than the lazy resolver
stub so, for example, r2 has not been pushed so does not needed
to be restored.
This fixes an intermittent failure in nptl/tst-tls3 when building
glibc for arm-linux-gnueabihf with -mtls-dialect=gnu2.
ChangeLog:
2014-05-27 Will Newton <will.newton@linaro.org>
[BZ #16990]
* sysdeps/arm/dl-tlsdesc.S (_dl_tlsdesc_resolve_hold): Save
and restore r2 rather than just restoring.

The offset computation in write mode uses the fact that _IO_read_end
is kept in sync with the external file offset. This however is not
true when O_APPEND is in effect since switching to write mode ought to
send the external file offset to the end of file without making the
necessary adjustment to _IO_read_end.
Hence in append mode, offset computation when writing should only
consider the effect of unflushed writes, i.e. from _IO_write_base to
_IO_write_ptr.
The wiki has a detailed document that describes the rationale for
offsets returned by ftell in various conditions:

The nested function mi_arena was removed from malloc_info
and made into a non-nested static inline function of the same
name with the correct set of arguments passed from malloc_info.
This enables building glibc with compilers that don't support
nested functions. Future work on malloc_info should remove these
functions entirely to support JSON format output. Therefore we
do the minimum required to remove the nested function.

This patch replaces the insrdi by insrwi in powerpc32 assembly.

Add a new 'init' directive that specifies the name of the function to
call to do function-specific initialization. This is useful for
benchmarks that need to do a one-time initialization before the
functions are executed.

This fixes a variety of testsuite failures for me:
tststatic.out Error 1
tststatic2.out Error 1
tst-tls9-static.out Error 1
tst-audit8.out Error 127
tst-audit9.out Error 127
tst-audit1.out Error 127
and also has the added benefit of making LD_AUDIT/sotruss work on
AArch64.
Otherwise, we bail out early in _dl_try_allocate_static_tls as the
alignment requirement of the PT_TLS section in libc is 16.

The netgroups nss modules in the glibc tree use NSS_STATUS_UNAVAIL
(with errno as ERANGE) when the supplied buffer does not have
sufficient space for the result. This is wrong, because the canonical
way to indicate insufficient buffer is to set the errno to ERANGE and
the status to NSS_STATUS_TRYAGAIN, as is used by all other modules.
This fixes nscd behaviour when the nss_ldap module returns
NSS_STATUS_TRYAGAIN to indicate that a netgroup entry is too long to
fit into the supplied buffer.

This macro was removed by
2005-11-16 Daniel Jacobowitz <dan@codesourcery.com>
but not applied to the (still separate) eabi port so necro'd
when the eabi port superceded the old abi. It was thence
copied into the new AArch64 port.

Move the error branch from the PSEUDO_RET macro to the PSEUDO macro.
This is in line with other architectures, and will enable further improvments.

While they do something for AArch32, they're useless for AArch64.
