* S390: Fp comparison are now raising FE_INVALID with gcc 10.Stefan Liebler2019-11-061-5/+7
| | | | | | | The s390 gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77918 "S390: Floating point comparisons don't raise invalid for unordered operands." is fixed with gcc 10. Thus we conditionally set FIX_COMPARE_INVALID to 0 or 1.
* S390: Add new s390 platform z15.Stefan Liebler2019-10-182-3/+3
| | | | | The new IBM z15 is added to platform string array. The macro _DL_PLATFORMS_COUNT is incremented.
* Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis2019-10-012-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With only two exceptions (sys/types.h and sys/param.h, both of which historically might have defined BYTE_ORDER) the public headers that include <endian.h> only want to be able to test __BYTE_ORDER against __*_ENDIAN. This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I *removed* copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER. Condition byteswapping macros only on !__ASSEMBLER__. Move the definitions of __BIG_ENDIAN, __LITTLE_ENDIAN, __PDP_ENDIAN, __FLOAT_WORD_ORDER, and __LONG_LONG_PAIR to... * string/bits/endian.h: ...this new file, which includes the renamed header bits/endianness.h for the definition of __BYTE_ORDER and possibly __FLOAT_WORD_ORDER. * string/Makefile: Install bits/endianness.h. * include/bits/endian.h: New wrapper. * bits/endian.h: Rename to bits/endianness.h.

* Declare most TS 18661-1 interfaces for C2X.Joseph Myers2019-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2X adds the interfaces from TS 18661-1, and all except a handful in Annex F are unconditionally visible in C2X rather than only visible when __STDC_WANT_IEC_60559_BFP_EXT__ is defined. This patch updates glibc headers accordingly: most uses of __GLIBC_USE (IEC_60559_BFP_EXT) are changed to a new __GLIBC_USE (IEC_60559_BFP_EXT_C2X).

* S390: Add arch13 memmem ifunc variant.Stefan Liebler2019-03-226-6/+201
| | | | | | | | | | | | | | | | | | | | This patch introduces the new arch13 ifunc variant for memmem. For needles longer than 9 bytes it is relying on the common-code implementation. For shorter needles it is using the new vstrs instruction which is able to search a substring within a vector register.

* S390: Add arch13 memmove ifunc variant.Stefan Liebler2019-03-225-5/+99
| | | | | | | | | | | | | | | | | | | | | This patch introduces the new arch13 ifunc variant for memmove. For the forward or non-overlapping case it is just using memcpy. For the backward case it relies on the new instruction mvcrl. The instruction copies up to 256 bytes at once. In case of an overlap, it copies the bytes like copying them one by one starting from right to left. ChangeLog: * sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_ARCH13, MEMMOVE_ARCH13 HAVE_MEMMOVE_IFUNC_AND_ARCH13_SUPPORT): New defines. * sysdeps/s390/memcpy-z900.S: Add arch13 memmove implementation. * sysdeps/s390/memmove.c (memmove): Add arch13 variant in ifunc selector. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variant for arch13 memmove. * sysdeps/s390/multiarch/ifunc-resolve.h (S390_STFLE_BITS_ARCH13_MIE3, S390_IS_ARCH13_MIE3): New defines.
* S390: Add configure check to detect support for arch13.Stefan Liebler2019-03-222-0/+120
| | | | | | | | | | | | | Add two configure checks which detect if arch13 is supported by the assembler at all - by explicitely setting the machine - and if it is supported with default settings.

| | | | | | | | | | | | | | | | | | | | | | The new hwcap values indicate support for: -"Vector-Enhancements Facility 2" (tag "vxe2", hwcap 2^15) -"Vector-Packed-Decimal-Enhancement Facility" (tag "vxp", hwcap 2^16) -"Enhanced-Sort Facility" (tag "sort", hwcap 2^17) -"Deflate-Conversion Facility" (tag "dflt", hwcap 2^18) The vxe2 hwcap is also marked as important hwcap. ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add vxe2, vxp, dflt, sort flags. * sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT capabilities. (HWCAP_IMPORTANT): Add HWCAP_S390_VXRS_EXT2. * sysdeps/unix/sysv/linux/s390/bits/hwcap.h (HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT): Define.
* S390: Mark vx and vxe as important hwcap.Stefan Liebler2019-03-211-1/+2
| | | | | | | | | | | This patch adds vx and vxe as important hwcaps which allows one to provide shared libraries tuned for platforms with non-vx/-vxe, vx or vxe. ChangeLog: * sysdeps/s390/dl-procinfo.h (HWCAP_IMPORTANT): Add HWCAP_S390_VX and HWCAP_S390_VXE.
* Remove obsolete, never-implemented XSI STREAMS declarationsFlorian Weimer2019-03-141-33/+0
| | | | | | | | | | | | | | | | | | | The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

* S390: Fix introduction of __wmemcmp and weak wmemcmp symbols.Stefan Liebler2019-02-061-1/+2
| | | | | | | | | | | | The recent commit 65f7767a914144ae303f7b9ae81865061793dcb9 has introduced __wmemcmp and the weak alias wmemcmp. This patch also introduces those symbols if glibc is build with CFLAGS="-march=z13" where the ifunc is omitted. ChangeLog: * sysdeps/s390/wmemcmp-vx.S: Add strong alias to __wmemcmp and weak alias to wmemcmp.
* Fix handling of collating elements in fnmatch (bug 17396, bug 16976)Andreas Schwab2019-02-041-3/+4
| | | | | | This fixes the same bug in fnmatch that was fixed by commit 7e2f0d2d77 for regexp matching. As a side effect it also removes the use of an unbound VLA.
