Reflow and sort Makefile. No code changes in generated binary artifacts. No regressions on x86_64 and i686.

Remove ia64-linux-gnu

2024-01-08T20:09:36Z

Linux 6.7 removed ia64 from the official tree [1], following the general principle that a glibc port needs upstream support for the architecture in all the components it depends on (binutils, GCC, and the Linux kernel). Apart from the removal of sysdeps/ia64 and sysdeps/unix/sysv/linux/ia64, there are updates to various comments referencing ia64 for which removal of those references seemed appropriate. The configuration is removed from README and build-many-glibcs.py. The CONTRIBUTED-BY, elf/elf.h, manual/contrib.texi (the porting mention), *.po files, config.guess, and longlong.h are not changed. For Linux it allows cleanup some clone2 support on multiple files. The following bug can be closed as WONTFIX: BZ 22634 [2], BZ 14250 [3], BZ 21634 [4], BZ 10163 [5], BZ 16401 [6], and BZ 11585 [7].

crypt: Remove libcrypt support

2023-10-30T16:03:59Z

All the crypt related functions, cryptographic algorithms, and make requirements are removed, with only the exception of md5 implementation which is moved to locale folder since it is required by localedef for integrity protection (libc's locale-reading code does not check these, but localedef does generate them). Besides thec code itself, both internal documentation and the manual is also adjusted. This allows to remove both --enable-crypt and --enable-nss-crypt configure options. Checked with a build for all affected ABIs. Co-authored-by: Zack Weinberg Reviewed-by: Carlos O'Donell

wchar: Define va_list for POSIX (BZ #30035)

2023-05-25T19:43:29Z

This was uncovered by a recent clang change [1]. Different than ISO C, POSIX states that va_list should be exported by wchar.h [2]. Checked on x86_64-linux-gnu and aarch64-linux-gnu.

Update copyright dates with scripts/update-copyrights

2022-01-01T19:40:24Z

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

Use $(pie-default) with conformtest

2021-09-17T19:24:14Z

My glibc bot showed that my conformtest changes fail the build of the conformtest execution tests for x86_64-linux-gnu-static-pie, because linking the newly built object with the newly built libc and the associated options normally used for linking requires it to be built as PIE. Add $(pie-default) to the compiler command used so that PIE options are used when required. There's a case for using the whole of $(CFLAGS-.o) (which includes $(pie-default)), but that raises questions of any impact from using optimization flags from CFLAGS in these tests. So for now just use $(pie-default) as the key part of $(CFLAGS-.o) that's definitely needed. Tested with build-many-glibcs.py for x86_64-linux-gnu-static-pie.
