The logic in setjmp/__longjmp incorrectly uses "PIC" to figure out
whether the code is going into a shared library when it should be
using "SHARED". If you build glibc with a gcc version that has PIE
enabled by default, then the code will try to use symbols that are
only in the shared library.

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).

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/libc-lock.h to plain libc-lock.h and
bits/libc-lockP.h to plain libc-lockP.h to follow that convention.
Note that I don't know where libc-lockP.h comes from for Hurd (the
Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in
the glibc source tree is for NPTL) - some unmerged patch? - but I
updated the #include in the Hurd libc-lock.h anyway.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

Depends on a gcc patch that makes protected visibility data non-local:

Concluding the fixes for C90 libm functions calling C99 fe* functions,
this patch fixes the case of feupdateenv by making it a weak alias for
__feupdateenv and making the affected code call __feupdateenv.
Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch). Also tested for ARM
(soft-float) that the math.h linknamespace tests now pass.

this patch fixes the case of fesetround by making it a weak alias of
__fesetround and making the affected code call __fesetround. An
existing __fesetround function in fenv_libc.h for powerpc is renamed
to __fesetround_inline.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch). Also tested for ARM
(soft-float) that fesetround failures disappear from the linknamespace
test results (feupdateenv remains to be addressed to complete fixing
bug 17748).

Some C90 libm functions call fegetenv via libc_feholdsetround*
functions in math_private.h. This patch makes them call __fegetenv
instead, making fegetenv into a weak alias for __fegetenv as needed.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch). Also tested for ARM
(soft-float) that fegetenv failures disappear from the linknamespace
test failures (however, similar fixes will also be needed for
fegetround, feholdexcept, fesetenv, fesetround and feupdateenv before
this set of namespace issues covered by bug 17748 is fully fixed and
those linknamespace tests start passing).

Various C90 and UNIX98 libm functions call feraiseexcept, which is not
in those standards. This causes linknamespace test failures - except
on x86 / x86_64, where feraiseexcept is inline (for the relevant
constant arguments) in bits/fenv.h.
This patch fixes this by making those functions call __feraiseexcept
instead. All changes are applied to all architectures rather than
considering the possibility that some might not be needed in some
cases (e.g. x86) as it seems most maintainable to keep architectures
consistent.
Where __feraiseexcept does not exist, it is added, with feraiseexcept
made a weak alias; where it is a strong alias, it is made weak.
libm_hidden_def / libm_hidden_proto are used with __feraiseexcept
(this might in some cases improve code generation for existing calls
to __feraiseexcept in some code on some architectures). Where there
are dummy feraiseexcept macros (on architectures without
floating-point exceptions support, to avoid compile errors from
references to undefined FE_* macros), corresponding dummy
__feraiseexcept macros are added. And on x86, to ensure
__feraiseexcept calls still get inlined, the inline function in
bits/fenv.h is refactored so that most of it can be reused in an
inline __feraiseexcept in a separate include/bits/fenv.h.
Calls are changed in C90/UNIX98 functions, but generally not in
functions missing from those standards. They are also changed in
libc_fe* functions (on the basis that those might be used in any libm
function), and in feupdateenv (on the same basis - may be used, via
default libc_*, in any libm function - of course feupdateenv will need
changing to __feupdateenv in a subsequent patch to make that fully
namespace-clean).
No __feraiseexcept is added corresponding to the feraiseexcept in
powerpc bits/fenvinline.h, because that macro definition is
conditional on !defined __NO_MATH_INLINES, and glibc libm is built
with -D__NO_MATH_INLINES, so changing internal calls to use
__feraiseexcept should make no difference.
Tested for x86_64 (testsuite; the only change in disassembly of
installed shared libraries is a slight code reordering in clog10, of
no apparent significance). Also tested for MIPS, where (in the
configuration tested) it eliminates math.h linknamespace failures for
n32 and n64 (some for o32 remain because of other issues).

GCC marked OABI obsolete in 4.7 and dropped it in 4.8. So the number
of people this is catching is shrinking every day. At this point,
it's not terribly useful, so just drop it.

This sets __HAVE_64B_ATOMICS if provided. It also sets
USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the
__atomic* builtins (aarch64, mips partially) or if this has been
tested (x86_64); otherwise, this is set to false so that C11 atomics will
be based on the existing atomic operations.

Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch eliminates its use for _dl_init. Since _dl_init was already
declared with hidden visibility, creating a second hidden alias for it
was completely pointless, so this patch replaces all uses of
_dl_init_internal with plain _dl_init instead of using hidden_proto /
hidden_def (which are only needed when you want a hidden alias for a
non-hidden symbol; it's quite possible there are cases where they are
used but don't need to be because the symbol in question is not part
of the public ABI and is only used within a single library, so using
attributes_hidden instead would suffice).
Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

This is a change to the dynamic linker to add prelinker support for the
R_ARM_TLS_DESC relocation. Two cases can be considered here, the usual
one where lazy binding is in use and the less frequent one, where
immediate binding is requested via the use of the DF_BIND_NOW dynamic
flag (e.g. by using the GNU linker's "-z now" option).
This change only handles the first case. In this scenario the prelinker
does what the dynamic linker would do, that is it preinitialises
R_ARM_TLS_DESC relocations with a pointer to the lazy specialization as
provided with the DT_TLSDESC_PLT dynamic tag. A conflict is
additionally created and in the conflict resolution path the dynamic
linker complements the work by initialising the object's pointer as
indicated by the DT_TLSDESC_GOT dynamic tag to the linker's internal
lazy specialization worker function and also providing the associated
link map in the second entry of the GOT. This step is required, because
if prelinking is successful at the run time, then the dynamic linker's
elf_machine_runtime_setup() function isn't called that would normally do
so.
The second case remains unresolved, because support for that scenario
has not been implemented in the prelinker. In this case the lazy
specialization is unavailable and the DT_TLSDESC_PLT dynamic tag is not
present.
The prelinker could assume the common case of static specialization and
resolve the relocation, but that would require the exposure of dynamic
linker's specialization worker function. Furthermore the dynamic linker
would have to handle the relocation in the conflict resolution path and
see if the dynamic specialization should be used instead. This however
would require access to data structures currently not made available to
the conflict resolution path and therefore a redesign of this part of
the dynamic linker.
Alternatively the prelinker could defer all processing to the dynamic
linker's conflict resolution path, but that would require similar access
to the said data structures.
Therefore the prelinker issues an error instead and the dynamic linker
has assertions to check that DT_TLSDESC_PLT and DT_TLSDESC_GOT are in
use in its conflict resolution path.
This change resolves all TLS failures in the prelinker testsuite, as
noted in the bug report, as well as the small test case provided there.
Unfortunately we don't seem to have any hooks to factor in the prelinker
(if present on a system) to testing, so at this time this fix has to
rely on using the prelinker test suite and enabling TLS descriptors
there for coverage.
[BZ #17078]
* sysdeps/arm/dl-machine.h (elf_machine_rela)
[RESOLVE_CONFLICT_FIND_MAP]: Handle R_ARM_TLS_DESC relocation.

Various architectures have files such as sysdeps/<arch>/shlib-versions
whose contents are in fact entirely Linux-specific, relating only to
the symbol / shared library versions for the port to Linux on that
architecture, when any future port to a different OS on that
architecture would use the symbol version of the glibc release it goes
in, as standard for new ports.
This patch moves such files under sysdeps/unix/sysv/linux/, merging in
the contents of sysdeps/<arch>/nptl/shlib-versions in the process.
The only bits not moved are those relating to libgcc_s versions, which
don't appear OS-specific in the same way that glibc's symbol versions
so. It deliberately does not change the regular expressions given for
matching configurations in each file; some match only Linux although
not Linux-specific, or match other OSes although Linux-specific. It
is with a view to at least the following further cleanups:
* Move architecture-specific content from the toplevel shlib-versions
and nptl/shlib-versions into sysdeps shlib-versions files, so
eliminating another difference between ex-ports and non-ex-ports
architectures.
* Likewise, for OS-specific content in shlib-versions files.
* At that point, the first field in shlib-versions files (the regular
expression matching a configuration triplet) should be redundant, so
eliminate that field and leave shlib-versions selection working
purely on a sysdeps basis (with limited use of %ifdef in
shlib-versions files when needed) rather than having its own
separate mechanism to select what configuration information is
relevant.
* Move the build of gnu/lib-names.h to a similar mechanism to that
used for gnu/stubs.h (each library build installing a version of the
header specifically for that build), so we can eliminate the
duplication of soname information in the makefiles and get it purely
from shlib-versions files again.
There may be other cleanups possible as well (in particular, I'm not
sure that all cases where the same "Earliest symbol set" information
is repeated for many different libraries actually should need to
repeat it rather than specifying it just once for DEFAULT for the
given configuration, and separately specifying any non-default choices
of soname).
Tested x86_64 that the installed shared libraries are unchanged by
this patch.
