* AArch64: Reformat inline-asm in elf_machine_load_addressAndrew Pinski2014-11-211-9/+12
| | | | | | | | | | | | | | | | | This patch reformats the inline-asm in elf_machine_load_address so it is easier to change only part of the inline-asm. That is using string concatenating instead of string continuation. Also document why this inline-asm works - it depends on the 32bit relocation being resolved at link time.

Also add comment.
* AArch64: Use ELF macros rather than Elf64 throughoutWill Newton2014-11-212-5/+5
| | | | | | | | | | | | | | | | | Using the macros for ELF types is required for adding ILP32 support. In the standard AArch64 configuration this makes no difference to the types used.

* Add arch-specific configuration for C11 atomics support.Torvald Riegel2014-11-201-0/+2
| | | | | | | | 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.

* [AArch64] Add optimized strchrnul.Richard Earnshaw2014-11-051-0/+130
| | | | | | | | | | | Here is an optimized implementation of __strchrnul. The simplification that we don't have to track precisely why the loop terminates (match or end-of-string) means we have to do less work in both setup and the core inner loop. That means this should never be slower than strchr. As with strchr, the use of LD1 means we do not need different versions for big-/little-endian.
* Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers2014-11-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-171-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Remove relro configure test.Joseph Myers2014-06-271-8/+0

The use of -z relro in Makeconfig became unconditional with commit 2e6ab1df44c412bb9d30b26a4d8a679150a7e375 Author: Ulrich Drepper <drepper@redhat.com> Date: Sat Oct 28 06:44:04 2006 +0000 Remove conditional code which now is unnecessary. (commit reference from git://repo.or.cz/glibc/history), so since then the configure test has not controlled anything about how glibc is built - simply about whether configure succeeds and allows a build to be attempted. The test for whether the option did something useful (as opposed to whether it exists - which we can certainly just assume by now) was originally added in <https://sourceware.org/ml/libc-hacker/2004-09/msg00069.html> to disable the option in a case when it did nothing useful on ia64 (as a result of something deliberate in the linker on ia64). Since 2006 that disabling has been of no effect, and given that the current test does not set libc_relro_required for ia64, it does nothing whatever useful for the original motivating case. Also at around the same time in 2006 the test was made to give an error for missing or broken -z relro support on various architectures. So effectively all the test does now is verify that, on certain architectures, the linker has not been changed deliberately to make the option ineffective. I see no apparent reason why such a change should be expected, or why the build should be stopped if it were to be made (any more than we disallow build on ia64); I think we can trust binutils patch review to point out the consequences of any change to COMMONPAGESIZE setting. The only thing that might now make sense would be disabling the -z relro use on an architecture-specific basis if there were an architecture-specific reason to consider that to make sense; it would be for the ia64 maintainer to decide if that makes sense for ia64 at present, but I think that could be done through sysdeps Makefiles - no special configure tests needed. Tested for x86_64 that this patch makes no change to the installed shared libraries. Together with <https://sourceware.org/ml/libc-alpha/2014-06/msg00788.html> (pending review) this substantially eliminates architecture-specific cases from architecture-independent configure.ac files. There remains an i386 case in sysdeps/mach/hurd/configure.ac that should properly move to the i386 subdirectory. (There are also OS-specific cases outside OS-specific directories; in principle I think should should also move.) * configure.ac (libc_commonpagesize): Remove variable.

* [AARCH64] correct alignment of TLS_TCB_ALIGN (BZ #16796)Kyle McMartin2014-05-261-2/+2
| | | | | | | | | | | | | | | 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.
