- Update to glibc 2.27
  * Optimized x86-64 asin, atan2, exp, expf, log, pow, atan, sin, cosf,
    sinf, sincosf and tan with FMA
  * Optimized x86-64 trunc and truncf for processors with SSE4.1
  * Optimized generic expf, exp2f, logf, log2f, powf, sinf, cosf and
    sincosf
  * In order to support faster and safer process termination the malloc API
    family of functions will no longer print a failure address and stack
    backtrace after detecting heap corruption
  * The abort function terminates the process immediately, without flushing
    stdio streams
  * On platforms where long double has the IEEE binary128 format (aarch64,
    alpha, mips64, riscv, s390 and sparc), the math library now implements
    _Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015
    These are the same interfaces added in version 2.26 for some platforms where
    this format is supported but is not the format of long double
  * On platforms with support for _Float64x (aarch64, alpha, i386, ia64,
    mips64, powerpc64le, riscv, s390, sparc and x86_64), the math library now
    implements interfaces for that type, as defined by ISO/IEC TS
    18661-3:2015
  * The math library now implements interfaces for the _Float32, _Float64 and
    _Float32x types, as defined by ISO/IEC TS 18661-3:2015
  * glibc now implements the memfd_create and mlock2 functions on Linux
  * Support for memory protection keys was added
  * The copy_file_range function was added
  * The ldconfig utility now processes `include' directives using the C/POSIX
    collation ordering
  * Support for two grammatical forms of month names has been added
  * Support for the RISC-V ISA running on Linux has been added
  * Statically compiled applications attempting to load locales compiled for the

+
+ 1. Small copies of up to 32 bytes
+ 2. Medium copies of 33..128 bytes which are fully unrolled

+
+ Large copies align the sourceto a quad word and use an unrolled loop
+ processing 64 bytes per iteration.
+
+ FALKOR-SPECIFIC DESIGN:
+
+ The smallest copies (32 bytes or less) focus on optimal pipeline usage,
+ which is why the redundant copies of 0-3 bytes have been replaced with
+ conditionals, since the former would unnecessarily break across multiple
+ issue groups. The medium copy group has been enlarged to 128 bytes since
+ bumping up the small copies up to 32 bytes allows us to do that without
+ cost and also allows us to reduce the size of the prep code before loop64.
+
+ All copies are done only via two registers r6 and r7. This is to ensure
+ that all loads hit a single hardware prefetcher which can get correctly
+ trained to prefetch a single stream.
+
+ The non-temporal stores help optimize cache utilization. */

Mon Feb 5 08:49:13 UTC 2018 - schwab@suse.de
- Update to glibc 2.27
* Optimized x86-64 asin, atan2, exp, expf, log, pow, atan, sin, cosf,
sinf, sincosf and tan with FMA
* Optimized x86-64 trunc and truncf for processors with SSE4.1
* Optimized generic expf, exp2f, logf, log2f, powf, sinf, cosf and
sincosf
* In order to support faster and safer process termination the malloc API
family of functions will no longer print a failure address and stack
backtrace after detecting heap corruption
* The abort function terminates the process immediately, without flushing
stdio streams
* On platforms where long double has the IEEE binary128 format (aarch64,
alpha, mips64, riscv, s390 and sparc), the math library now implements
_Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015
These are the same interfaces added in version 2.26 for some platforms where
this format is supported but is not the format of long double
* On platforms with support for _Float64x (aarch64, alpha, i386, ia64,
mips64, powerpc64le, riscv, s390, sparc and x86_64), the math library now
implements interfaces for that type, as defined by ISO/IEC TS
18661-3:2015
* The math library now implements interfaces for the _Float32, _Float64 and
_Float32x types, as defined by ISO/IEC TS 18661-3:2015
* glibc now implements the memfd_create and mlock2 functions on Linux
* Support for memory protection keys was added
* The copy_file_range function was added
* The ldconfig utility now processes `include' directives using the C/POSIX
collation ordering
* Support for two grammatical forms of month names has been added
* Support for the RISC-V ISA running on Linux has been added
* Statically compiled applications attempting to load locales compiled for the
GNU C Library version 2.27 will fail and fall back to the builtin C/POSIX
locale
* Support for statically linked applications which call dlopen is deprecated
and will be removed in a future version of glibc
* Support for old programs which use internal stdio data structures and
functions is deprecated
* On GNU/Linux, the obsolete Linux constant PTRACE_SEIZE_DEVEL is no longer
defined by <sys/ptrace.h>
* libm no longer supports SVID error handling (calling a user-provided
matherr function on error) or the _LIB_VERSION variable to control error
handling
* The libm functions pow10, pow10f and pow10l are no longer supported for
new programs
* The mcontext_t type is no longer the same as struct sigcontext
* The add-ons mechanism for building additional packages at the same time as
glibc has been removed
* The res_hnok, res_dnok, res_mailok and res_ownok functions now check that
the specified string can be parsed as a domain name
* In the malloc_info output, the <heap> element may contain another <aspace>
element, "subheaps", which contains the number of sub-heaps
* In the malloc_info output, the <heap> element may contain another <aspace>
element, "subheaps", which contains the number of sub-heaps
* The nonstandard header files <libio.h> and <_G_config.h> are deprecated
and will be removed in a future release
* CVE-2018-6485: The posix_memalign and memalign functions, when called with
an object size near the value of SIZE_MAX, would return a pointer to a
buffer which is too small, instead of NULL (bsc#1079036)
- Support for Sun RPC is no longer available, use libtirpc instead

* math/math.h: Let signbit use the builtin in C++ mode with gcc

[BZ #22235]
* sysdeps/ieee754/ldbl-96/bits/iscanonical.h (iscanonical):
Provide a C++ implementation based on function overloading,
rather than using __MATH_TG, which uses C-only builtins.

Likewise.

math/math.h: Let fpclassify use the builtin in C++ mode, even
when optimazing for size.
2017-08-28 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
[BZ #21930]
* math/math.h [defined __cplusplus && defined __SUPPORT_SNAN__]
(iszero): New C++ implementation that does not use
fpclassify/__MATH_TG/__builtin_types_compatible_p, when
signaling nans are enabled, since __builtin_types_compatible_p
is a C-only feature.
2017-08-24 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
* math/math.h [defined __cplusplus] (issignaling): In the long
double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH
is not defined. Call __issignaling, otherwise.
2017-08-22 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
* math/math.h [defined __cplusplus] (issignaling): Provide a C++
definition for issignaling that does not rely on __MATH_TG,
since __MATH_TG uses __builtin_types_compatible_p, which is only
available in C mode.
2017-08-18 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
[BZ #21930]
* math/math.h (isinf): Check if in C or C++ mode before using
__builtin_types_compatible_p, since this is a C mode feature.
2017-08-18 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
* misc/sys/cdefs.h (__HAVE_GENERIC_SELECTION): Define to 0, if
