Re: Call for testing: elftoolchain tools

As part of a project to update our toolchain I've started working on using some of the tools from the elftoolchain project. There is now a build knob to enable the use of the following tools: * addr2line * elfcopy (strip) * nm * size * strings The knob (in /etc/src.conf) is: WITH_ELFTOOLCHAIN_TOOLS=yes The binutils version is still used for as, ld, objcopy, objdump and readelf; future projects will handle these. The option is being tested in ports exp-runs on amd64 and i386, and has had basic sanity testing on arm64 and mips64. I'm interested in test reports across a variety of hardware architectures and use cases. If everything works as expected you should see no difference -- the tools should be drop-in replacements. -Ed ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org I was running WITH_ELFTOOLCHAIN_TOOLS for a few days on head/amd64 and clang350-import/amd64. Things build and work as before. I'm not seeing any behavior differences. - Nikolai Lifanov ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
Re: Call for testing: elftoolchain tools
FWIW, A nice testing procedure, or even a pet project if generalized, would be to test the tools with a fuzzer like security/afl. Apparently the GNU binutils and Fedora elfutils developers having doing that [1]. Regards, Pedro.
