egrep and fgrep have been deprecated for a long time, and the next grep release will emit a warning if egrep or fgrep is invoked:
https://git.savannah.gnu.org/cgit/grep.git/commit/?id=a951562 To prevent us from a lot of these warnings in the future, we should stop using egrep and fgrep. These patches will remove most of the use of egrep or fgrep from GCC building system. The remaining: * The configure scripts generated by autoconf-2.69 will still refer to "egrep", but they will try "grep -E" first and only try egrep when "grep -E" is not available. * libgo: Left for Ian because I'm not familiar with it. * maintainer-scripts/update_web_docs_libstdcxx_git: Left for Jonathan because I don't think other people will invoke it. * libffi: Already submitted https://github.com/libffi/libffi/pull/720. * contrib/gen_autofdo_event.py and gcc/config/i386/gcc-auto-profile: I'll make a patch later (now download.01.org seems down so I can't test or regenerate gcc-auto-profile) porting gen_autofdo_event.py to Python 3.
