Subject: Test multiplying two long long ints.
X-Git-Tag: V_7_4_P1~154
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a8fc0f42e1eda2fa3393d1ea5e61322d5e07a9cd;p=thirdparty%2Fopenssh-portable.git

Test multiplying two long long ints.

When using clang with -ftrapv or -sanitize=integer the tests would pass
but linking would fail with "undefined reference to __mulodi4".
Explicitly test for this before enabling -trapv.
