Subject: Fix turn off optimization in case of configure --enable-gcov
X-Git-Tag: v7.6.0~133
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=45896dc;p=libatomic_ops

Fix turn off optimization in case of configure --enable-gcov
(fix commit 0d0a16d)

* configure.ac [enable_gcov] (CFLAGS): Change sed regular expression
to avoid [] (as they are not properly handled during autogen), and to
also filter out -Os and -Ofast (-O0 is ignored).
