* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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
* Properly check stack alignment [BZ #27901]H.J. Lu2021-05-241-0/+28
1. Replace if ((((uintptr_t) &_d) & (__alignof (double) - 1)) != 0) which may be optimized out by compiler, with int __attribute__ ((weak, noclone, noinline)) is_aligned (void *p, int align) { return (((uintptr_t) p) & (align - 1)) != 0; } 2. Add TEST_STACK_ALIGN_INIT to TEST_STACK_ALIGN. 3. Add a common TEST_STACK_ALIGN_INIT to check 16-byte stack alignment for both i386 and x86-64. 4. Update powerpc to use TEST_STACK_ALIGN_INIT.
