Hello!

2011-06-05  Uros Bizjak  <ubiz...@gmail.com>

        * config/i386/i386.md (*movdf_internal_rex64) <case 8,9,10>:
        Remove MODE_TI handling.  Remove SSE1 handling in attribute "mode"
        calculation.
        (*movdf_internal_rex64) <case 6,7,8>: Remove MODE_TI handling.
        Simplify MODE_V1DF and MODE_V2SF handling.
        (*movsf_internal): Remove x constraint from operand 1 alternative 7.
        Simplify MODE_SF handling.

Patch was bootstrapped and regression tested on x86_64-pc-linux-gnuj
{,-m32} AVX target. Committed to mainline SVN.

Uros.
