Hello!
We should avoid to allocate "r" in *_nointeger instructions.
Constraint modifiers apply to a following character, not to the whole
alternative.
2011-05-06 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.md (*movdf_internal_nointeger): Apply "*"
constraint modifier to "r".
Tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN and
(soon) 4.6 branch.
Uros.
