I understand current status and hope binutils is successfully removed from base system before the release of 13.0. --- Yasuhiro KIMURA ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

There's no specific plan, but it is an ongoing goal. Only three binutils tools are used (for bootstrapping and in the installed system): as, ld, and objdump. BINUTILS_BOOTSTRAP is enabled on x86, 32-bit arm, and powerpc. At least both x86 archs still use GNU as for a few files; there's work in progress to migrate to Clang's IAS for all assembly files. I am not sure if bootstrap as actually gets used on arm or powerpc. objdump is also built, but not used on any arch. ld is built on powerpc and still being used there; it's not built on x86 or 32-bit arm. Making further progress depends on lld maturing (for powerpc) and addressing the assembler issue. There's no commitment to removing binutils for 13.0 but there is a reasonable probability we'll be able to do so. ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"

However, it looks like it's not used except for powerpc. I'd expect that once the issues there are resolved with clang, or that platform migrates to an external toolchain, binutils in base's days will be numbered since it is GPL and the project has a long term goal of being GPL free where possible.

Using a decade-old binutils with a contemporary compiler (either Clang or GCC) isn't likely to be a combination used by anyone else and it's not going to be a good use of our time investigating and addressing any issues that arise. ___ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
