= Proposed System Wide Change: Binutils 2.31 = https://fedoraproject.org/wiki/Changes/BINUTILS231 Owner(s): * Nick Clifton <nickc at redhat dot com> Rebase the binutils package from version 2.30 to version 2.31. == Detailed description == Switch the binutils package from being based on the 2.30 release of the FSF binutils to being based on the 2.31 release. This release will bring in numerous bug fixes, as well as the following new features: The linker can now put all code and read-only data sections into a separate segment with only READ and EXECUTE permissions. All writable data can be placed into a separate segment with READ and WRITE permissions. This makes programs larger, but safer. The linker's behaviour can be controlled via a command line option, and the default set by a configure option. The assembler can generate build notes for any input files which do not contain their own notes. Again this is controlled via a command line option whose default is set by a configure option. The x86 assembler supports a new -O[2|s] command-line option to enable alternate, shorter instruction encoding. It also supports a ,nop pseudo-op to simplify the insertion of NOP instruction sequences. The AArch64 assembler will now warn a combintation of an instruction and a register name are invalid. The AArch64 disassembler will now also flag inconsistent instruction encodings. The "ar" program will now accept an "O" modifier to its command line, which causes the offsets of members within the archive to be displayed alongside the other information. == Scope == * Proposal owners: Change the source parameter in the binutils.spec rpm and adjust the local patches to take account of the bugs that are now already fixed.This should be followed by a mass rebuild in order for the changes to be noticed across the system. * Other developers: No other work should be necessary. Once the rebase is in place and the buildroot contains the new binutils its use should be automatic.It is possible that the new linker feature might prove to be problematic forsome packages, although no such problems are anticipated. If this doeshappen however the package maintainers can add a command line optionto disable the new linker feature. * Release engineering: https://pagure.io/releng/issue/7573 ** List of deliverables: Just the binutils package. * Policies and guidelines: No updates needed. * Trademark approval: N/A (not needed for this Change) -- Jan Kuřík JBoss EAP Program Manager Red Hat Czech s.r.o., Purkynova 99/71, 612 45 Brno, Czech Republic _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/AOIRUAYXRAH46EHTQGXAORKQDPTGTCN3/
