Other Activity This Week
- Optimized version of powf()
Paul Clarke: Most significant changes are code simplification and use of doubles for intermediate values. - powerpc: fix sysconf support for cache geometries
Paul Clarke: Commit cdfbe5037f2f67bf5f560b73732b69d0fabe2314 added sysconf support for cache geometries on powerpc, but mishandled errno. - powerpc: Add optimized version of [l]lroundf
Rajalakshmi Srinivasaraghavan: This patch makes use of optimized double version of llround for single precision as both the versions return [long] long type. - Support _Float128 in ldbl-96 bits/iscanonical.h
Joseph Myers: This patch adds _Float128 support to the ldbl-96 bits/iscanonical.h, as needed for x86_64 / x86 / ia64 support of _Float128. - Support _Float128 in math-tests.h
Joseph Myers: This patch makes math-tests.h, as used to describe support of given floating-point types for sNaNs, rounding modes and exceptions, handle distinguishing _Float128 from long double. - Make errno-setting libm templates include errno.h
Joseph Myers: Various type-generic libm wrapper templates, as used for float128, set errno but do not include errno.h. - Add ChangeLog entries for the last 3 commits
Siddhesh Poyarekar: I forgot to add ChangeLog entries for my last three commits. - Bug 21533: Update to Unicode 10.0.0
Mike FABIAN: - Unicode 10. - Implement allocation buffers for internal use
Florian Weimer: This commit adds fixed-size allocation buffers. - x86-64: Implement strcmp family IFUNC selectors in C
H.J. Lu: Implement strcmp family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. - [AArch64] Add more cfi annotations to tlsdesc entry points
Szabolcs Nagy: Backtrace through _dl_tlsdesc_resolve_rela was broken because the offset of x30 from cfa was not in the debug info. - Factor out shared definitions from bits/signum.h
Zack Weinberg: Many of the things defined by bits/signum.h are invariant across all supported operating systems. - Add powf trace
Wilco Dijkstra: Add a workload for powf. - tunables: Add IFUNC selection and cache sizes
H.J. Lu: The current IFUNC selection is based on microbenchmarks in glibc. - Improve math benchmark infrastructure
Wilco Dijkstra: Improve support for math function benchmarking. - Remove bits/string.h
Zack Weinberg: These machine-dependent inline string functions have never been on by default, and even if they were a good idea at the time they were introduced, they haven't really been touched in ten to fifteen years and probably aren't a good idea on current-gen processors.
glibc Release Tags
- Update for 2.25 release
Siddhesh Poyarekar - Update version.h and include/features.h for 2.22 release
Carlos O'Donell - Restore _POSIX2_C_VERSION definition (bug 438).
Joseph Myers: My review of conformtest expectations for POSIX showed up that the _POSIX2_C_VERSION macro, required by POSIX and XPG standards before 2001, was missing in unistd.h, having been removed on 2003-04-03 despite those standards still being supported. - Bump required version of texinfo to 4.7
Will Newton: It seems we require texinfo 4.7 for the --plaintext option, so document that and check for the correct version in configure. ChangeLog: 2014-12-15 Will Newton - manual/install.texi: Bump required version of texinfo to 4.7 from 4.5. - INSTALL: Regenerated. - configure.ac: Check for makeinfo version 4.7 and above. - configure: Regenerated. - Rework compiler version check in configure
Roland McGrath - Update version.h and include/features.h for 2.19 release
Allan McRae - Accept make versions 4.0 and greater
Marc-Antoine Perennou - Update version.h and include/features.h for 2.18 release
David S. Miller - Make _LIB_VERSION a weak symbol
Siddhesh Poyarekar: That way it can live alongside _LIB_VERSION in libieee.a for statically compiled programs.
Most Popular In The Past Month
- Enable tunables by default
Siddhesh Poyarekar: All of the major architectures are adopting tunables as a way to add tuning to the library, from hwcap_mask for aarch64 to HLE for s390 and ifunc and cache geometry for x86. - Add internal facility for dynamic array handling
Florian Weimer: This is intended as a type-safe alternative to obstacks and hand-written realloc constructs. - posix: Implement preadv2 and pwritev2
Adhemerval Zanella: This patch adds support of preadv2 and pwritev2 which are similar to preadv/pwritev but with an extra flag argument. - x86-64: Implement strcpy family IFUNC selectors in C
H.J. Lu: Implement strcpy family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. - Add a way to bypass the PLT when calling getauxval
Tulio Magno Quites Machado Filho: - include/sys/auxv.h (__getauxval): Add a prototype and its libc_hidden_proto. - ld.so: Consolidate 2 strtouls into _dl_strtoul [BZ #21528]
H.J. Lu: There are 2 minimal strtoul implementations in ld.so: 1. - powerpc: add sysconf support for cache geometries
Paul Clarke: There is currently no "cross-platform" (x86 and POWER) support for determining the cacheline size. This patch adds support to sysconf() to correctly report cacheline sizes based on the information in the auxilliary vector. Thus, using sysconf() is a cross-platform (x86 and POWER) solution for determining cacheline sizes. Support is added (on powerpc) for: _SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE _SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE _SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE _SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE - sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file. - x86-64: Optimize memrchr with AVX2
H.J. Lu: Optimize memrchr with AVX2 to search 32 bytes with a single vector compare instruction. - PowerPC64 ENTRY_TOCLESS
Alan Modra: A number of functions in the sysdeps/powerpc/powerpc64/ tree don't use or change r2, yet declare a global entry that sets up r2. - x86-64: Implement memset family IFUNC selectors in C
H.J. Lu: Implement memset family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register.
