I am getting warnings
clang: warning: argument unused during compilation: '-faddress-sanitizer'
when building with
$ clang --version
clang version 2.9 (tags/RELEASE_29/final)
Target: i386-redhat-linux-gnu
Thread model: posix
I just assumed that my clang version was too old to know this switch.
Since only the -clang-debug target was affected, I didn't care.
I would prefer -clang-debug just using the option name that is required
for the newest clang version(s), instead of having to adjust one more
config variable.
But when I change the option name in Makefile, I get
clang: warning: argument unused during compilation: '-fsanitize=address'
instead, for 2.9 and for 3.1.
This is bad. May be HAVE_CLANG_3_2 is a good enough solution right now?
How widespread is clang 3.2? Fedora 18 still uses 3.1.
