Subject: target/arm: Check for dp support for dp VFM, not sp
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=34bea4edb9bbe8edf4b8606276482acdff5ca58b;p=people%2Fdariof%2Fqemu-xen.git

target/arm: Check for dp support for dp VFM, not sp

In commit 1120827fa182f0e7622 we accidentally put the
"UNDEF unless FPU has double-precision support" check in
the single-precision VFM function. Put it in the dp
function where it belongs.
