* [PATCH 1/6] Split x86_64 out of main Linux kernel-features.h.Joseph Myers2014-07-173-9/+52
| | | | | | | | | | | | | | | | | This patch splits x86_64 out of the main Linux kernel-features.h. Tested x86_64 that there are no changes to disassembly of installed shared libraries. * sysdeps/unix/sysv/linux/x86_64/kernel-features.h: New file. * sysdeps/unix/sysv/linux/kernel-features.h [__x86_64__] (__ASSUME_ACCEPT4_SYSCALL): Do not define.

* Refactor handling of /lib64 etc. cases, move out of sysdeps/gnu/configure.ac.Joseph Myers2014-07-1718-132/+192
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues removing architecture-specific cases from non-architecture-specific files by moving the logic to use directories such as /lib64 out of sysdeps/gnu/configure.ac. A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure scripts can use to declare the library directories to be used; the logic was previously duplicated in configure fragments for aarch64, mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is used directly in sysdeps/gnu/configure.ac only to provide the /lib default (the logic saying that with --prefix=/usr shared libraries go in /lib not /usr/lib); the architecture cases formerly there are moved into various new or existing configure.ac files. The new macro is also used in the various architecture fragments that already had such logic. In the x32 there was previously a configure fragment, but it was a directly written one without a .ac file; now a .ac file is used there instead to generate configure. Tested x86_64 that the installed shared libraries, and the directory structure of the installation, are unchanged by this patch. There is an old bug report - bug 6441 - about library directories changing after reconfiguring. If this is still applicable - and I haven't attempted to confirm it or review the old patch pointed to in that bug - then this patch should reduce the number of places needing changing in any fix. * aclocal.m4 (LIBC_SLIBDIR_RTLDDIR): New macro. * sysdeps/gnu/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. Remove cases for individual architectures. * sysdeps/gnu/configure: Regenerated. * sysdeps/unix/sysv/linux/aarch64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/aarch64/configure: Regenerated. * sysdeps/unix/sysv/linux/mips/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/mips/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac: Use LIBC_SLIBDIR_RTLDDIR. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * sysdeps/unix/sysv/linux/s390/s390-64/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/s390-64/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/sparc64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/64/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/x32/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/x32/configure: Generate.
* Move architecture shlib-versions files to Linux-specific directories.Joseph Myers2014-07-1718-17/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. * sysdeps/aarch64/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/aarch64/shlib-versions: ... here. * sysdeps/alpha/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/alpha/shlib-versions: ... here. * sysdeps/arm/shlib-versions: Move to ... * sysdeps/unix/sysv/linux/arm/shlib-versions: ... here. * sysdeps/hppa/shlib-versions: Move all contents except for libgcc_s entry to ... * sysdeps/unix/sysv/linux/hppa/shlib-versions: ... here.

* iconv/loop.c: Fix -Wundef warning with !_STRING_ARCH_unalignedWill Newton2014-07-172-30/+34
| | | | | | | | | | | | | | | | | | If code is required to handle the unaligned case then loop.c includes itself and relies on the #undefs at the end of the file to avoid outputting two copies of LOOPFCT and gconv_btowc. However MAX_NEEDED_INPUT is tested with #if so this causes a warning. Reorder the code so that the function definitions are in an #else block to make the behaviour clearer and fix the warning. Verified that code is unchanged on x86_64 and arm. ChangeLog: 2014-07-17 Will Newton <will.newton@linaro.org> * iconv/loop.c: Move definition of LOOPFCT and gconv_btowc into an #else block.

We address by checking that all calls to set*id on all threads give the same result, and only abort if we see success followed by failure (or vice versa).

* Fix crash when system has no ipv6 address [BZ #17125]Siddhesh Poyarekar2014-07-103-2/+13
| | | | | | | | | | | Here's an updated patch to fix the crash in bug-ga2 when the system has no configured ipv6 address. I have taken a different approach of using libc_freeres_fn instead of the libc_freeres_ptr since the former gives better control over what is freed; we need that since cache may or may not be allocated using malloc. Verified that bug-ga2 works correctly in both cases and does not have memory leaks in either of them.

* Fix -Wundef warnings for SHAREDWill Newton2014-07-096-5/+13
| | | | | | | | | | | | | | | | | The definition of SHARED is tested with #ifdef pretty much everywhere apart from these few places. The tlsdesc.c code seems to be copy and pasted to a few architectures and there is one instance in the hppa startup code. ChangeLog: 2014-07-09 Will Newton <will.newton@linaro.org> * sysdeps/aarch64/tlsdesc.c (_dl_unmap): Test SHARED with #ifdef. * sysdeps/arm/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/i386/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/x86_64/tlsdesc.c (_dl_unmap): Likewise. * sysdeps/hppa/start.S (_start): Likewise.
* Fix -Wmaybe-uninitialized warning in xdr.cSiddhesh Poyarekar2014-07-092-1/+3
| | | | | | | | | | While we're at fixing build warnings, here's one unnecessary warning that can be fixed fairly easily. The SIZE variable is never actually use uninitialized, but the compiler cannot make that out and thinks (correctly) that there is a potential for accessing SIZE without initializing it. Make this safe by initializing SIZE to 0. Tested on x86_64.
* Fix Wundef warning for __cplusplusSiddhesh Poyarekar2014-07-092-1/+6
| | | | | All current uses of the __cplusplus macro only check if it is defined or not. Fix this #if to use $ifdef like the rest of the code.
* Check value at resplen2 if it is not NULLSiddhesh Poyarekar2014-07-082-4/+8
| | | | | | | There was a typo in the previous patch due to which resplen2 was checked for non-zero instead of the value at resplen2. Fix that and improve the condition by checking resplen2 for non-NULL (instead of answerp2) and also adding the check in a third place.

* PowerPC: Cleanup powerpc memmoveAdhemerval Zanella2014-07-086-25/+15
| | | | | | | Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code.
* PowerPC: Fix compiler warningsAdhemerval Zanella2014-07-084-3/+12
| | | | | This patch fixes some compiler due trailing data in #undef directives and due missing prototypes.

* Fix Wundef warning with SHOJI_IS_RIGHTSiddhesh Poyarekar2014-07-0818-468/+37

* PowerPC: Align power7 memcpy using VSX to quadwordAdhemerval Zanella2014-07-073-20/+10
| | | | | | This patch changes power7 memcpy to use VSX instructions only when memory is aligned to quardword. It is to avoid unaligned kernel traps on non-cacheable memory (for instance, memory-mapped I/O).
* PowerPC: optimized memmove for POWER7/PPC32Adhemerval Zanella2014-07-075-1/+109
| | | | | This patch adds a optimized memmove for power7 by using the optimized power7 memcpy for forward copying.
* PowerPC: optimized memmove for POWER7/PPC64Adhemerval Zanella2014-07-0711-2/+1037
| | | | | | | | | | | This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.
* PowerPC: memmove default implementation cleanupAdhemerval Zanella2014-07-072-97/+5
| | | | | | | | This patch removes the powerpc specific logic in memmove and instead include default implementation with MEMCPY_OK_FOR_FWD_MEMMOVE defined. This lead in a increase performance, since the constraints to use memcpy in powerpc code are too restrictive and memcpy can be used for any forward memmove.
* PowerPC: Guard CALL_ELF check for ppc64 only in link.hAdhemerval Zanella2014-07-072-2/+9
| | | | | This patch fixes powerpc32 undef compiler warnings for _CALL_ELF, since it is defined only for powerpc64.
