* Faster memcpy on x64.Ondrej Bilka2013-05-204-8/+185
| | | | | | | | | We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2

* MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki2013-05-162-0/+2
| | | | | | | | [BZ #15442] This adds support for the inverse interpretation of the quiet bit of IEEE 754 floating-point NaN data that some processors use. This includes in particular MIPS architecture processors; the payload used for the canonical qNaN encoding is updated accordingly so as not to interfere with the quiet bit.
* Add #include <stdint.h> for uint[32|64]_t usage (except installed headers).Ryan S. Arnold2013-05-1631-5/+33

* Use movq for 64-bit operationsPeter Collingbourne2013-05-151-2/+4
| | | | | | | | | | | The EXTRACT_WORDS64 and INSERT_WORDS64 macros use movd for a 64-bit operation. Somehow gcc manages to turn this into movq, but LLVM won't. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/math_private.h (MOVQ): New macro. (EXTRACT_WORDS64) Use where appropriate. (INSERT_WORDS64) Likewise.
* Use x constraints for operands to vfmaddss and vfmaddsdPeter Collingbourne2013-05-152-2/+2
| | | | | | | | | | | | | | | While these instructions accept memory operands, only one operand may be a memory operand. Giving two operands xm constraints gives the compiler the option of using memory for both operands, which would result in invalid assembly code. Using x for all operands is more appropriate, as most x86_64 calling conventions will pass the arguments in registers anyway. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/multiarch/s_fma.c (__fma_fma4): Replace xm constraints with x constraints. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c (__fmaf_fma4): Likewise.

| | | | | | | | | | 2013-05-15 Edjunior Machado <emachado@linux.vnet.ibm.com> * sysdeps/unix/sysv/linux/s390/bits/siginfo.h (siginfo_t): Remove si_trapno and add si_addr_lsb to _sifields.sigfault. (si_trapno): Remove macro. (si_addr_lsb): Define new macro. (BUS_MCEERR_AR, BUS_MCEERR_AO): Define new values.

* Make _LIB_VERSION a weak symbolSiddhesh Poyarekar2013-05-131-4/+5
| | | | | | | That way it can live alongside _LIB_VERSION in libieee.a for statically compiled programs. Resolves #14582.

* PowerPC: Add time vDSO supportAdhemerval Zanella2013-05-034-3/+70
| | | | | | | | PowerPC kernel now provides a vDSO implementation for time syscall (commit fcb41a2030abe0eb716ef0798035ef9562097f42). This patch changes time syscall wrapper to use the vDSO when available. It also changes the default non vDSO time on PowerPC to use sysdeps/posix/time.c (since gettimeofday is a vDSO call).
* Sync with Linux 3.9Andreas Jaeger2013-05-032-1/+4
| | | | | | | | * sysdeps/gnu/netinet/tcp.h (TCP_TIMESTAMP): New value, from Linux 3.9. * sysdeps/unix/sysv/linux/bits/socket.h (PF_VSOCK, AF_VSOCK): Add. (PF_MAX): Adjust for VSOCK change.

| | | | | | | This patch fix the 3c0265394d9ffedff2b0de508602dc52e077ce5c commits by correctly setting minimum architecture for modf PPC optimization to power5+ instead of power5 (since only on power5+ round/ceil will be inline to inline assembly).

* S/390: Change struct statfs[64] member types to unsigned valuesHeiko Carstens2013-04-231-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kay Sievers reported that coreutils' stat tool has a problem with s390's statfs[64] definition: > The definition of struct statfs::f_type needs a fix. s390 is the only > architecture in the kernel that uses an int and expects magic > constants lager than INT_MAX to fit into. > > A fix is needed to make Fedora boot on s390, it currently fails to do > so. Userspace does not want to add code to paper-over this issue. [...] > Even coreutils cannot handle it: > #define RAMFS_MAGIC 0x858458f6 > # stat -f -c%t / > ffffffff858458f6 > > #define BTRFS_SUPER_MAGIC 0x9123683E > # stat -f -c%t /mnt > ffffffff9123683e The bug is caused by an implicit sign extension within the stat tool: out_uint_x (pformat, prefix_len, statfsbuf->f_type); where the format finally will be "%lx". A similar problem can be found in the 'tail' tool. s390 is the only architecture which has an int type f_type member in struct statfs[64]. Other architectures have either unsigned ints or long values, so that the problem doesn't occur there. Therefore change the type of the f_type member to unsigned int, so that we get zero extension instead sign extension when assignment to a long value happens.
