2018-12-18S390: Refactor wcsncpy ifunc handling.Stefan Liebler
The ifunc handling for wcsncpy is adjusted in order to omit ifunc if the minimum architecture level already supports newer CPUs by default. Unfortunately the c ifunc variant can't be omitted at all as it is used by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned. ChangeLog: * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove wcsncpy variants. * sysdeps/s390/Makefile (sysdep_routines): Add wcsncpy variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for wcsncpy. * sysdeps/s390/multiarch/wcsncpy-c.c: Move to ... * sysdeps/s390/wcsncpy-c.c: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsncpy-vx.S: Move to ... * sysdeps/s390/wcsncpy-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/wcsncpy.c: Move to ... * sysdeps/s390/wcsncpy.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-wcsncpy.h: New file.

2018-12-18S390: Add z13 memmove ifunc variant.Stefan Liebler
This patch introduces a z13 specific ifunc variant for memmove. As the common code implementation, it checks if we can copy from the beginning to the end - with z196 memcpy implementation - or if we have to copy from the end to the beginning. The latter case is done by using vector load/store instructions. If vector instructions are not available, the common-code is used as fallback. Therefore it is implemented in memmove-c with a different name. Furthermore the ifunc logic decides if we need the common-code implementation at all. If vector instructions are supported due to the minimum architecture level set we can skip the common-code ifunc variant. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmove-c. * sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC, HAVE_MEMMOVE_IFUNC_AND_VX_SUPPORT, MEMMOVE_DEFAULT, HAVE_MEMMOVE_C, MEMMOVE_C, HAVE_MEMMOVE_Z13, MEMMOVE_Z13): New defines. * sysdeps/s390/memcpy-z900.S: Add z13 memmove implementation. * sysdeps/s390/memmove-c.c: New file. * sysdeps/s390/memmove.c: Likewise. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for memmove.

2018-12-18S390: Use memcpy for forward cases in memmove.Stefan Liebler

2018-12-18S390: Remove s390 specific implementation of bcopy.Stefan Liebler
Nowadays gcc is automatically replacing a call to bcopy with a call to memmove. Thus only old binaries will call the s390 specific bcopy implementation. The s390 specific implementation is using an own implementation for memcpy in the forward case and is relying on memmove in the backward case. After removing the s390 specific bcopy, the common code bcopy is used. It just performs a tail call to memmove. ChangeLog: * sysdeps/s390/s390-32/bcopy.S: Remove. * sysdeps/s390/s390-64/bcopy.S: Likewise.
2018-12-18S390: Refactor memcpy/mempcpy ifunc handling.Stefan Liebler
This patch moves all ifunc variants for memcpy/mempcpy to sysdeps/s390/memcpy-z900.S. The configure-check/preprocessor logic in sysdeps/s390/ifunc-memcpy.h decides if ifunc is needed at all and which ifunc variants should be available. E.g. if the compiler/assembler already supports z196 by default, the older ifunc variants are not included. If we only need the newest ifunc variant, then we can skip ifunc at all. Therefore the ifunc-resolvers and __libc_ifunc_impl_list are adjusted in order to handle only the available ifunc variants. ChangeLog: * sysdeps/s390/ifunc-memcpy.h: New File. * sysdeps/s390/memcpy.S: Move to ... * sysdeps/s390/memcpy-z900.S ... here.

The implementation of memcpy/mempcpy for s390-32 (31bit) and s390-64 (64bit) is nearly the same. This patch unifies it for maintability reasons. __mem[p]cpy_z10 and __mem[p]cpy_z196 differs between 31 and 64bit: -31bit needs .machinemode "zarch_nohighgprs" and llgfr %r4,%r4 -lr vs lgr; lgr can be also used on 31bit as this ifunc variant is only called if we are on a zarch machine. __mem[p]cpy_default differs between 31 and 64bit: -Some 31bit vs 64bit instructions (e.g. ltr vs ltgr.

2018-12-18S390: Use hwcap instead of dl_hwcap in ifunc-resolvers.Stefan Liebler
The renaming of hwcap arguments in ifunc-resolvers is needed in order to prepare for further commits which refactors ifunc handling for memset, memcmp, and memcpy.

2018-12-17Add test that MAP_* constants agree with kernel.Joseph Myers
Continuing the process of building up and using Python infrastructure for extracting and using values in headers, this patch adds a test that MAP_* constants from sys/mman.h agree with those in the Linux kernel headers. (Other sys/mman.h constants could be added to the test separately.) This set of constants has grown over time, so the generic code is enhanced to allow saying extra constants are OK on either side of the comparison (where the caller sets those parameters based on the Linux kernel headers version, compared with the version the headers were last updated from). Although the test is a custom Python file, my intention is to move in future to a single Python script for such tests and text files it takes as inputs, once there are enough examples to provide a guide to the common cases in such tests (I'd like to end up with most or all such sets of constants copied from kernel headers having such tests, and likewise for structure layouts from the kernel). The Makefile code is essentially the same as for tst-signal-numbers, but I didn't try to find an object file to depend on to represent the dependency on the headers used by the test (the conform/ tests don't try to represent such header dependencies at all, for example). Tested with build-many-glibcs.py, and also for x86_64 with older kernel headers. * scripts/glibcextract.py (compare_macro_consts): Take parameters to allow extra macros from first or second sources. * sysdeps/unix/sysv/linux/tst-mman-consts.py: New file. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (tests-special): Add $(objpfx)tst-mman-consts.out.
