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

2019-09-07Prefer https to http for gnu.org and fsf.org URLsPaul Eggert
Also, change sources.redhat.com to sourceware.org. This patch was automatically generated by running the following shell script, which uses GNU sed, and which avoids modifying files imported from upstream: sed -ri ' s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g ' \ $(find $(git ls-files) -prune -type f \ ! -name '*.po' \ ! -name 'ChangeLog*' \ ! -path COPYING ! -path COPYING.LIB \ ! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ ! '(' -name configure \ -execdir test -f configure.ac -o -f configure.in ';' ')' \ !

2018-02-07Fix -Os gnu_dev_* linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers
Building with -Os produces linknamespace and localplt failures for, among other functions, gnu_dev_major, gnu_dev_minor and gnu_dev_makedev. The issue is that those functions are not inlined when building with -Os. While one could force them to be inlined in that case, it seems more natural to fix this issue similarly to other namespace issues. Thus, this patch makes gnu_dev_* into weak aliases for hidden symbols __gnu_dev_*; __gnu_dev_* are then defined as inlines in the internal include/sys/sysmacros.h, and uses of gnu_dev_* (often via the macros major, minor and makedev) for which there are namespace issues are changed to use __gnu_dev_*; where there are no namespace issues, use of libc_hidden_proto serves to avoid unnecessary local PLT entry use. Tested for x86_64, (a) without -Os, to verify the testsuite continues to pass without problems and that the functions called under their new names continue to be inlined as expected in that case; (b) with -Os, to verify that the linknamespace and localplt failures in question go away (but because of other such failures present, neither of the relevant bugs can yet be closed).

2016-08-03Minimize sysdeps code involved in defining major/minor/makedev.Zack Weinberg
Presently sys/sysmacros.h is entirely defined in sysdeps. This would mean that the deprecation logic coming up in the next patch would have to be written twice (in generic/ and unix/sysv/linux/). To avoid that, hoist all but the unavoidably system-dependent logic to misc/, leaving a bits/ header behind. This also promotes the Linux-specific encoding of dev_t, which accommodates 32-bit major and minor numbers in a 64-bit dev_t, to generic, as glibc's dev_t is always 64 bits wide. The former Linux implementation used inline functions to avoid evaluating arguments more than once. After this change, all platforms use inline functions, which means that three new symbols are added to the generic ABI. (These symbols are in the user namespace, which is how they have always been on Linux. They begin with "gnu_dev_", so collisions with user code are pretty unlikely.) New ports henceforth need only provide a bits/sysmacros.h defining internal macros __SYSMACROS_{DECLARE,DEFINE}_{MAJOR,MINOR,MAKEDEV}. This is only necessary if the kernel encoding is incompatible with the now-generic encoding (for instance, it would be necessary for FreeBSD). While I was at it, I added a basic round-trip test for these functions. * sysdeps/generic/sys/sysmacros.h: Delete file. * sysdeps/unix/sysv/linux/makedev.c: Delete file. * sysdeps/unix/sysv/linux/sys/sysmacros.h: Move file ... * bits/sysmacros.h: ... here; this encoding is now the generic encoding. Now defines only the following macros: __SYSMACROS_DECLARE_MAJOR, __SYSMACROS_DEFINE_MAJOR, __SYSMACROS_DECLARE_MINOR, __SYSMACROS_DEFINE_MINOR, __SYSMACROS_DECLARE_MAKEDEV, __SYSMACROS_DEFINE_MAKEDEV. * misc/sys/sysmacros.h, misc/makedev.c: New files that use bits/sysmacros.h and the above new macros to generate the public implementations of major, minor, and makedev. * misc/tst-makedev.c: New test. * include/sys/sysmacros.h: New wrapper. * misc/Makefile (headers): Add sys/sysmacros.h, bits/sysmacros.h.
