* Add install dependencies for ld -> bfd and libctf -> bfdusers/nalcock/ld-ctf-install-depsNick Alcock2021-03-173-2/+23
| | | | | | | | | | | | | | | | | This stops problems parallel-installing if a relink of libctf is needed. Also adds corresponding install-strip dependencies. ChangeLog 2021-03-02 Nick Alcock <nick.alcock@oracle.com> PR libctf/27482 * Makefile.def: Add install-bfd dependencies for install-libctf and install-ld, and install-strip-bfd dependencies for install-strip-libctf and install-strip-ld; move the install-ld dependency on install-libctf to join it. * Makefile.in: Regenerated.
* PowerPC64 undefined weak visibility vs GOT optimisationAlan Modra2021-03-029-0/+115
| | | | | | | | | | | | | | | | | | | | | | Undefined weak symbols with non-default visibility are seen as local by SYMBOL_REFERENCES_LOCAL. This stops a got indirect to relative optimisation for them, so that pies and dlls don't get non-zero values when loading somewhere other than the address they are linked at (which always happens). The optimisation could be allowed for pdes, but I thought it best not to allow it there too. bfd/ * elf64-ppc.c (ppc64_elf_relocate_section): Don't optimise got indirect to pc-relative or toc-relative for undefined symbols. ld/ * testsuite/ld-powerpc/weak1.d, * testsuite/ld-powerpc/weak1.r, * testsuite/ld-powerpc/weak1.s, * testsuite/ld-powerpc/weak1so.d, * testsuite/ld-powerpc/weak1so.r: New tests. * testsuite/ld-powerpc/powerpc.exp: Run them.

* PR27441, inconsistency in weak definitionsAlan Modra2021-03-013-3/+20
| | | | | | | | | | | | | | | This makes IR objects use the same logic as normal objects with respect to what sort of ref/def makes an as-needed library needed. Testing the binding of the definition is just plain wrong. What matters is the binding of the reference.

* Use make_tempname file descriptor in smart_renameAlan Modra2021-02-266-35/+82
| | | | | | | | | | | | | | | | | | | | | | | | This patch makes use of the temp file descriptor in smart_rename rather than reopening the file. I don't believe there is a security issue in reopening the file, but this way is one less directory operation. The patch also attempts to preserve S_ISUID and S_ISGID. PR 27456 * bucomm.h (smart_rename): Update prototype. * rename.c (smart_rename): Add fromfd and preserve_dates params. Pass fromfd and target_stat to simple_copy. Call set_times when preserve_dates.

* Reinstate various pieces backed out from smart_rename changesAlan Modra2021-02-265-19/+42
| | | | | | | | | | | | | | | | | | | | In the interests of a stable release various last minute smart_rename patches were backed out of the 2.36 branch. The main reason to reinstate some of those backed out changes here is to make necessary followup fixes to commit 8e03235147a9 simple cherry-picks from mainline. A secondary reason is that ar -M support isn't fixed for pr26945 without this patch. PR 26945 * ar.c: Don't include libbfd.h. (write_archive): Replace xmalloc+strcpy with xstrdup. * arsup.c (temp_name, real_ofd): New static variables. (ar_open): Use make_tempname and bfd_fdopenw.

* binutils: Avoid renaming over existing filesSiddhesh Poyarekar2021-02-226-54/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Renaming over existing files needs additional care to restore permissions and ownership, which may not always succeed. Additionally, other properties of the file such as extended attributes may be lost, making the operation flaky. For predictable results, resort to rename() only if the file does not exist, otherwise copy the file contents into the existing file. This ensures that no additional tricks are needed to retain file properties. This also allows dropping of the redundant set_times on the tmpfile in objcopy/strip since now we no longer rename over existing files. binutils/ * ar.c (write_archive): Adjust call to SMART_RENAME. * arsup.c (ar_save): Likewise. * objcopy (strip_main): Don't set times on temporary file and adjust call to SMART_RENAME. (copy_main): Likewise. * rename.c [!S_ISLNK]: Remove definitions. (try_preserve_permissions): Remove function. (smart_rename): Replace PRESERVE_DATES argument with TARGET_STAT. Use rename system call only if TO does not exist. * bucomm.h (smart_rename): Adjust declaration. (cherry picked from commit 3685de750e6a091663a0abe42528cad29e960e35)
