Subject: s390: Undo part of r2501. The "convert to fixed" opcodes always have an m3
X-Git-Tag: svn/VALGRIND_3_9_0^2~260
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=559e709791ab61975e880888e2988f1640ab4ee0;p=thirdparty%2Fvalgrind.git

s390: Undo part of r2501. The "convert to fixed" opcodes always have an m3
field -- independent of the floating point extension facility.
So do not issue an emulation warning for those opcodes.
