Subject: FreeBSD regtest: add syscall 9999 to scalar
X-Git-Tag: VALGRIND_3_26_0~99
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e30bd17b037f4f402a020f8674b1ae576c5cfcc;p=thirdparty%2Fvalgrind.git

FreeBSD regtest: add syscall 9999 to scalar

This provokes an unhandled syscall message, as is done on other
platforms. Update filter since scalar runs on all FreeBSD
platforms.
