Subject: Moved Vex's arch/subarch detection out of main() into VG_(translate)()'s
X-Git-Tag: svn/VALGRIND_3_0_0~651
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=96329ab01548241329c342a545f5ed87fb161a05;p=thirdparty%2Fvalgrind.git

Moved Vex's arch/subarch detection out of main() into VG_(translate)()'s
init routine.  This meant that VG_(vex_arch) and VG_(vex_subarch) could be
made local to VG_(translate)().
