* S390: Influence hwcaps/stfle via GLIBC_TUNABLES.Stefan Liebler2023-02-0712-64/+423
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables the option to influence hwcaps and stfle bits used by the s390 specific ifunc-resolvers. The currently x86-specific tunable glibc.cpu.hwcaps is also used on s390x to achieve the task. In addition the user can also set a CPU arch-level like z13 instead of single HWCAP and STFLE features. Note that the tunable only handles the features which are really used in the IFUNC-resolvers. All others are ignored as the values are only used inside glibc. Thus we can influence: - HWCAP_S390_VXRS (z13) - HWCAP_S390_VXRS_EXT (z14) - HWCAP_S390_VXRS_EXT2 (z15) - STFLE_MIE3 (z15) The influenced hwcap/stfle-bits are stored in the s390-specific cpu_features struct which also contains reserved fields for future usage. The ifunc-resolvers and users of stfle bits are adjusted to use the information from cpu_features struct. On 31bit, the ELF_MACHINE_IRELATIVE macro is now also defined. Otherwise the new ifunc-resolvers segfaults as they depend on the not yet processed_rtld_global_ro@GLIBC_PRIVATE relocation.

* Add string vectorized find and detection functionsAdhemerval Zanella2023-02-066-0/+402
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds generic string find and detection meant to be used in generic vectorized string implementation. The idea is to decompose the basic string operation so each architecture can reimplement if it provides any specialized hardware instruction. The 'string-misc.h' provides miscellaneous functions: - extractbyte: extracts the byte from an specific index. - repeat_bytes: setup an word by replicate the argument on each byte. The 'string-fza.h' provides zero byte detection functions: - find_zero_low, find_zero_all, find_eq_low, find_eq_all, find_zero_eq_low, find_zero_eq_all, and find_zero_ne_all The 'string-fzb.h' provides boolean zero byte detection functions: - has_zero: determine if any byte within a word is zero. - has_eq: determine byte equality between two words. - has_zero_eq: determine if any byte within a word is zero along with byte equality between two words. The 'string-fzi.h' provides positions for string-fza.h results: - index_first: return index of first zero byte within a word. - index_last: return index of first byte different between two words. The 'string-fzc.h' provides a combined version of fza and fzi: - index_first_zero_eq: return index of first zero byte within a word or first byte different between two words. - index_first_zero_ne: return index of first zero byte within a word or first byte equal between two words. - index_last_zero: return index of last zero byte within a word. - index_last_eq: return index of last byte different between two words. The 'string-shift.h' provides a way to mask off parts of a work based on some alignmnet (to handle unaligned arguments): - shift_find, shift_find_last.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a flag that causes open () to create a new, unnamed file in the same filesystem as the given directory. The file descriptor can be simply used in the creating process as a temporary file, or shared with children processes via fork (), or sent over a Unix socket. The file can be left anonymous, in which case it will be deleted from the backing file system once all copies of the file descriptor are closed, or given a permanent name with a linkat () call, such as the following: int fd = open ("/tmp", O_TMPFILE | O_RDWR, 0700); /* Do something with the file... */ linkat (fd, "", AT_FDCWD, "/tmp/filename", AT_EMPTY_PATH); In between creating the file and linking it to the file system, it is possible to set the file content, mode, ownership, author, and other attributes, so that the file visibly appears in the file system (perhaps replacing another file) atomically, with all of its attributes already set up. The Hurd support for O_TMPFILE directly exposes the dir_mkfile RPC to user programs. Previously, dir_mkfile was used by glibc internally, in particular for implementing tmpfile (), but not exposed to user programs through a Unix-level API. O_TMPFILE was initially introduced by Linux. This implementation is intended to be compatible with the Linux implementation, except that the O_EXCL flag is not given the special meaning when used together with O_TMPFILE, unlike on Linux.
