2018-02-06Unify and simplify bits/byteswap.h, bits/byteswap-16.h headers (bug 14508, ↵Joseph Myers
bug 15512, bug 17082, bug 20530). We have a general principle of preferring optimizations for library facilities to use compiler built-in functions rather than being located in library headers, where the compiler can reasonably optimize code without needing to know glibc implementation details. This patch applies this principle to bits/byteswap.h, eliminating all the architecture-specific variants and bits/byteswap-16.h. The __bswap_16, __bswap_32 and __bswap_64 interfaces all become inline functions, never macros, using the GCC built-in functions where available and otherwise a single architecture-independent definition using shifts and masking (which compilers may well be able to detect and optimize; GCC has detection of various byte-swapping idioms). The __bswap_constant_32 macro needs to stay around because of uses in static initializers within glibc and its tests, and so for consistency all __bswap_constant_* are kept rather than just being inlined into the old-GCC-or-non-GCC parts of the __bswap_* inline function definitions. Various open bugs are addressed by this cleanup, with caveats about exactly what is covered by those bugs and when the bugs applied at all. Bug 14508 reports -Wformat warnings building glibc because __bswap_* sometimes returned the wrong types. Obviously we already don't have such warnings any more or the build would be failing, given -Werror, and I suspect that bug was originally for wrong types for x86_64, as fixed by commit d394eb742a3565d7fe7a4b02710a60b5f219ee64 (glibc 2.17). The only case I saw removed by this patch where the types would still have been wrong was the non-__GNUC__ case of __bswap_64 in the s390 header (using unsigned long long int, but uint64_t would be unsigned long int for 64-bit). In any case, the single header consistently uses __uintN_t types after this patch, thereby eliminating all such bugs. The existing string/test-endian-types.c test already suffices to verify that the types are correct with the compiler used to build glibc and its tests. Bug 15512 reports an error from __bswap_constant_16 with -Werror -Wsign-conversion. I am unable to reproduce this with any GCC version supporting -Wsign-conversion - all seem to be able to avoid warning for ((x) >> 8) & 0xffu, where x is uint16_t, which while it formally does involve an implicit conversion from int to unsigned int, is also a case where it should be easy for the compiler to see that the value converted is never negative. But in this patch __bswap_constant_16 is changed to use signed 0xff so that no such implicit conversion occurs at all, and a test with -Werror -Wsign-conversion is added. Bug 17082 objects to the use of ({}) statement expressions in these macros preventing use at file scope (in C, that's in sizeof etc.; in C++, more generally in static initializers). The particular case of these interfaces is fixed by this patch as it changes them to inline functions, eliminating all uses of ({}) in bits/byteswap.h, and a corresponding testcase is added. The bug tries to raise a more general policy question about use of ({}) in macros in installed headers, referring to "many other libc functions" (unspecified which functions are being considered). Since such policy questions belong on libc-alpha, and since there *are* macros in installed headers which can't really avoid using ({}) (where they are type-generic, so can't use an inline function, but need a temporary variable, and a few where the interface involves returning memory from alloca so can't use an inline function either), I propose to consider that bug fixed with this change. That is without prejudice to any other new bugs anyone wishes to file *for precisely defined sets of macros* requesting moving away from ({}) *where it is clearly possible for those interfaces*. Where ({}) can be avoided, typically by use of an inline function, I think that's a good idea - that inline functions are typically to be preferred to ({}) for header interfaces where such optimizations are useful but the interface is suited to being defined using an inline function. Bug 20530 requests use of __builtin_bswap16 when available (GCC 4.8 and later), which this patch implements. Tested for x86_64, and with build-many-glibcs.py. Also did an x86_64 test with the __GNUC_PREREQ conditionals changed to "#if 0" to verify the old-GCC/non-GCC case in the headers.

2017-06-20Remove 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.

2016-12-14Refactor long double information into bits/long-double.h.Joseph Myers
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86. Also did compilation-only testing with build-many-glibcs.py. * bits/long-double.h: New file. * sysdeps/ieee754/ldbl-128/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-96/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-opt/bits/long-double.h: Likewise. * sysdeps/mips/bits/long-double.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/long-double.h: Likewise. * math/Makefile (headers): Add bits/long-double.h. * misc/sys/cdefs.h: Include <bits/long-double.h>. * stdlib/strtold.c: Include <bits/long-double.h> instead of <bits/wordsize.h>. * bits/mathdef.h [!_COMPLEX_H]: Do not allow inclusion.

2016-12-01Refactor FP_ILOGB* out of bits/mathdef.h.Joseph Myers
Continuing the refactoring of bits/mathdef.h, this patch stops it defining FP_ILOGB0 and FP_ILOGBNAN, moving the required information to a new header bits/fp-logb.h. There are only two possible values of each of those macros permitted by ISO C. TS 18661-1 adds corresponding macros for llogb, and their values are required to correspond to those of the ilogb macros in the obvious way. Thus two boolean values - for which the same choices are correct for most architectures - suffice to determine the value of all these macros, and by defining macros for those boolean values in bits/fp-logb.h we can then define the public FP_* macros in math.h and avoid the present duplication of the associated feature test macro logic. This patch duly moves to bits/fp-logb.h defining __FP_LOGB0_IS_MIN and __FP_LOGBNAN_IS_MIN. Default definitions of those to 0 are correct for both architectures, while ia64, m68k and x86 get their own versions of bits/fp-logb.h to reflect their use of values different from the defaults. The patch renders many copies of bits/mathdef.h trivial (needed only to avoid the default __NO_LONG_DOUBLE_MATH). I'll revise <https://sourceware.org/ml/libc-alpha/2016-11/msg00865.html> accordingly so that it removes all bits/mathdef.h headers except the default one and the alpha one, and arranges for the header to be included only by complex.h as the only remaining use at that point will be for the alpha ABI issues there. Tested for x86_64 and x86.

2016-11-24Refactor float_t, double_t information into bits/flt-eval-method.h.Joseph Myers
At present, definitions of float_t and double_t are split among many bits/mathdef.h headers. For all but three architectures, these types are float and double. Furthermore, if you assume __FLT_EVAL_METHOD__ to be defined, that provides a more generic way of determining the correct values of these typedefs. Defining these typedefs more generally based on __FLT_EVAL_METHOD__ was previously proposed by Paul Eggert in <https://sourceware.org/ml/libc-alpha/2012-02/msg00002.html>. This patch refactors things in the way I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>. A new header bits/flt-eval-method.h defines a single macro, __GLIBC_FLT_EVAL_METHOD, which is then used by math.h to define float_t and double_t. The default is based on __FLT_EVAL_METHOD__ (although actually a default to 0 would have the same effect for current ports, because ports where values other than 0 or 16 are possible all have their own headers). To avoid changing the existing semantics in any case, including for compilers not defining __FLT_EVAL_METHOD__, architecture-specific files are then added for m68k, s390, x86 which replicate the existing semantics. At least with __FLT_EVAL_METHOD__ values possible with GCC, there should be no change to the choices of float_t and double_t for any supported configuration. Architecture maintainer notes: * m68k: sysdeps/m68k/m680x0/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 2 to replicate the existing logic. But actually GCC defines __FLT_EVAL_METHOD__ to 0 if TARGET_68040. It might make sense to make the header prefer to base things on __FLT_EVAL_METHOD__ if defined, like the x86 version, and so make the choices of these types more accurate (with a NEWS entry as for the other changes to these types on particular architectures). * s390: sysdeps/s390/bits/flt-eval-method.h always defines __GLIBC_FLT_EVAL_METHOD to 1 to replicate the existing logic. As previously discussed, it might make sense in coordination with GCC to eliminate the historic mistake, avoid excess precision in the -fexcess-precision=standard case and make the typedefs match (with a NEWS entry, again). Tested for x86-64 and x86. Also did compilation-only testing with build-many-glibcs.py. * bits/flt-eval-method.h: New file. * sysdeps/m68k/m680x0/bits/flt-eval-method.h: Likewise. * sysdeps/s390/bits/flt-eval-method.h: Likewise. * sysdeps/x86/bits/flt-eval-method.h: Likewise. * math/Makefile (headers): Add bits/flt-eval-method.h. * math/math.h: Include <bits/flt-eval-method.h>.

2016-03-31S390: Extend structs La_s390_regs / La_s390_retval with vector-registers.Stefan Liebler
Starting with z13, vector registers can also occur as argument registers. Thus the passed input/output register structs for la_s390_[32|64]_gnu_plt[enter|exit] functions should reflect those new registers. This patch extends these structs La_s390_regs and La_s390_retval and adjusts _dl_runtime_profile() to handle those fields in case of running on a z13 machine. ChangeLog: * sysdeps/s390/bits/link.h: (La_s390_vr) New typedef. (La_s390_32_regs): Append vector register lr_v24-lr_v31. (La_s390_64_regs): Likewise.

2016-02-18Add _STRING_INLINE_unaligned and string_private.hH.J. Lu
As discussed in https://sourceware.org/ml/libc-alpha/2015-10/msg00403.html the setting of _STRING_ARCH_unaligned currently controls the external GLIBC ABI as well as selecting the use of unaligned accesses withing GLIBC. Since _STRING_ARCH_unaligned was recently changed for AArch64, this would potentially break the ABI in GLIBC 2.23, so split the uses and add _STRING_INLINE_unaligned to select the string ABI. This setting must be fixed for each target, while _STRING_ARCH_unaligned may be changed from release to release. _STRING_ARCH_unaligned is used unconditionally in glibc. But <bits/string.h>, which defines _STRING_ARCH_unaligned, isn't included with -Os. Since _STRING_ARCH_unaligned is internal to glibc and may change between glibc releases, it should be made private to glibc. _STRING_ARCH_unaligned should defined in the new string_private.h heade file which is included unconditionally from internal <string.h> for glibc build.

2015-09-11Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/atomic.h to atomic-machine.h to follow that convention. This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2015-08-26S390: Optimize strcmp and wcscmp.Stefan Liebler
This patch provides optimized versions of strcmp and wcscmp with the z13 vector instructions. The architecture specific string.h had a typo, which leads to ommiting the inline version in this file if __USE_STRING_INLINES is defined. Tested this inline version by tweaking test-strcmp.c.

2014-11-20Add arch-specific configuration for C11 atomics support.Torvald Riegel
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.
