Subject: Make the assembler-knows-POWER-DFP test a bit stricter, since it appears
X-Git-Tag: svn/VALGRIND_3_8_0~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e176db35912ae555197d2bed833a95f3d5e771ed;p=thirdparty%2Fvalgrind.git

Make the assembler-knows-POWER-DFP test a bit stricter, since it appears
some older assemblers know 'dadd' but not 'dcffix', which also appears
in the DFP tests.
