Subject: ppc: The functions dis_dfp_fmt_conv and dis_dfp_exponent_test
X-Git-Tag: svn/VALGRIND_3_11_0^2~3^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f2a4aca00e65849c5e2e82c89dcc066617dbe033;p=thirdparty%2Fvalgrind.git

ppc: The functions dis_dfp_fmt_conv and dis_dfp_exponent_test
should only be executed in case DFP is supported. Add missing
guards.
