| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
* aarch64: Optimize __libc_mtag_tag_regionSzabolcs Nagy2021-03-261-18/+80
| | | | | | | | This is a target hook for memory tagging, the original was a naive implementation. The optimized version relies on "dc gva" to tag 64 bytes at a time for large allocations and optimizes small cases without adding too many branches. This was not benchmarked on real cpu, but expected to be faster than the naive implementation.

* aarch64: Add aarch64-specific files for memory tagging supportRichard Earnshaw2020-12-211-0/+51
This final patch provides the architecture-specific implementation of the memory-tagging support hooks for aarch64.
