From 2a8ec611ac2feef30716066e031a32004e5664d0 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Mon, 21 Nov 2022 11:25:38 +0800 Subject: tools/memory-model: Use "grep -E" instead of "egrep" The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/memory-model` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang Reviewed-by: Akira Yokosawa Signed-off-by: Paul E.
