# Specify -o /dev/null so the output of -S is discarded. More importantly
# It does not try to create a file with the name "null.s" on POSIX and
# "nul.s" on Windows. Because on Windows "nul" is a reserved file name.
# Beware that /dev/null is not available to mingw tools, so directly use
# "nul" instead of "/dev/null" if we're building on a mingw machine.
# Specify the path to gcc/testsuite/selftests within the srcdir
# as an argument to -fself-test.
