Subject: Initialize s390_host_hwcaps early in LibVEX_FrontEnd.
X-Git-Tag: svn/VALGRIND_3_13_0^2~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8cb14e1dbdc7d3c9243f938608338cdc63ff970b;p=thirdparty%2Fvalgrind.git

Initialize s390_host_hwcaps early in LibVEX_FrontEnd.

VEX svn r3341 split LibVEX_Translate into LibVEX_FrontEnd and
LibVEX_BackEnd. The s390_host_hwcaps (KLUDGE) needs to be initialized
early in LibVEX_FrontEnd.
