Subject: libtool: Support "-fno-sanitize*" options.
X-Git-Tag: v2.5.0~69
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8878355f1d531933a23e705bdaafcd180d803c9b;p=thirdparty%2Flibtool.git

libtool: Support "-fno-sanitize*" options.

"-fno-sanitize*" options e.g. -fno-sanitize=alignment
or -fno-sanitize-recover=all are used to tune the behvior of
sanitizers in GCC/clang. Let libtool pass these options
to compiler similar to fsanitize=*.

* build-aux/ltmain.in: Handle -fno-sanitize*.
