manual/libm-err-tab.pl hardcodes a list of names for particular
platforms (mapping from sysdeps directory name to friendly name for
the manual). This goes against the principle of keeping information
about individual platforms in their corresponding sysdeps directory,
and the list is also very out-of-date regarding supported platforms
and their corresponding sysdeps directories.
This patch fixes this by adding a libm-test-ulps-name file alongside
each libm-test-ulps file. The script then gets the friendly name from
that file, which is required to exist, so it no longer needs to allow
for the mapping being missing.
Tested for x86_64.

This patch makes sysdeps/tile/preconfigure handle tilegx* machine
names instead of just plain tilegx. That matches GCC, and in
particular allows a big-endian toolchain to use the tilegxbe-linux-gnu
name when configuring both GCC and glibc.
Tested with compilation for tilegxbe-linux-gnu, both 32-bit and 64-bit
(building a subsequent GCC against that glibc still falls over because
of both 32-bit and 64-bit libraries going in the lib directory, as
noted at
<https://sourceware.org/ml/libc-alpha/2016-11/msg00129.html>).
* sysdeps/tile/preconfigure: Accept tilegx* instead of tilegx.

TS 18661-1 defines a type femode_t to represent the set of dynamic
floating-point control modes (such as the rounding mode and trap
enablement modes), and functions fegetmode and fesetmode to manipulate
those modes (without affecting other state such as the raised
exception flags) and a corresponding macro FE_DFL_MODE.
This patch series implements those interfaces for glibc. This first
patch adds the architecture-independent pieces, the x86 and x86_64
implementations, and the <bits/fenv.h> and ABI baseline updates for
all architectures so glibc keeps building and passing the ABI tests on
all architectures. Subsequent patches add the fegetmode and fesetmode
implementations for other architectures.
femode_t is generally an integer type - the same type as fenv_t, or as
the single element of fenv_t where fenv_t is a structure containing a
single integer (or the single relevant element, where it has elements
for both status and control registers) - except where architecture
properties or consistency with the fenv_t implementation indicate
otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic
pointer value (-1 cast to const femode_t *), a value that can be
distinguished from valid pointers by its high bits but otherwise
contains a representation of the desired register contents, or a
pointer to a constant variable (the powerpc case; __fe_dfl_mode is
added as an exported constant object, an alias to __fe_dfl_env).
Note that where architectures (that share a register between control
and status bits) gain definitions of new floating-point control or
status bits in future, the implementations of fesetmode for those
architectures may need updating (depending on whether the new bits are
control or status bits and what the implementation does with
previously unknown bits), just like existing implementations of
<fenv.h> functions that take care not to touch reserved bits may need
updating when the set of reserved bits changes. (As any new bits are
outside the scope of ISO C, that's just a quality-of-implementation
issue for supporting them, not a conformance issue.)
As with fenv_t, femode_t should properly include any software DFP
rounding mode (and for both fenv_t and femode_t I'd consider that
fragment of DFP support appropriate for inclusion in glibc even in the
absence of the rest of libdfp; hardware DFP rounding modes should
already be included if the definitions of which bits are status /
control bits are correct).
Tested for x86_64, x86, mips64 (hard float, and soft float to test the
fallback version), arm (hard float) and powerpc (hard float, soft
float and e500). Other architecture versions are untested.

Identical definitions of dtv_t and TLS_DTV_UNALLOCATED were
repeated for all architectures using DTVs.

This avoids build failures in the tests, and matches what is in
bits/mathdef.h.
Update the libc and libm abilist files to include __finitel,
__isinfl, and __isnanl.

Various math_private.h headers are guarded by "#ifndef
_MATH_PRIVATE_H", but never define the macro. Nothing else defines
the macro either (the generic math_private.h that they include defines
a different macro, _MATH_PRIVATE_H_), so those guards are ineffective.
With the recent inclusion of s_sin.c in s_sincos.c, this breaks the
build for MIPS, since the build of s_sincos.c ends up including
<math_private.h> twice and the MIPS version defines inline functions
such as libc_feholdexcept_mips, without a separate fenv_private.h
header with its own guards such as some architectures have.
This patch fixes all the problem headers to use architecture-specific
guard macro names, and to define those macros in the headers they
guard, just as some architectures already do.
Tested for x86 (testsuite, and that installed shared libraries are
unchanged by the patch), and for mips64 (that it fixes the build).

This mostly automatically-generated patch converts 231 sysdeps
function definitions in glibc from old-style K&R to prototype-style.
For __aio_sigqueue and __gai_sigqueue I had to add internal_function
to the definitions as noted by Florian in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00595.html> to keep
the functions compiling on x86 after conversion to prototype
definitions. Otherwise, the patch is automatically generated with all
the same exclusions and caveats as in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> except
that it's a patch for sysdeps files.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch). Also tested for arm,
mips64 and powerpc32 that installed stripped shared libraries are
unchanged by the patch.

The implementation of lround in dbl-64/wordsize-64 as an alias or
wrapper for llround is always incorrect when long is not 64-bit,
because it misses required exceptions in overflow cases, as shown by
my recently added tests. This patch removes that alias / wrapper in
the non-LP64 case, together with the REGISTER_CAST_INT32_TO_INT64
macro, restoring the previous version of lround for dbl-64/wordsize-64
(newly conditioned on !_LP64).
Tested for x86_64, and for mips64 with use of dbl-64/wordsize-64
enabled.

It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/atomic.h to atomic-machine.h to follow that
convention.
This is the only change in this series that needs to change the
filename rather than simply removing a directory level (because both
atomic.h and bits/atomic.h exist at present).
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).
