    PR target/77874
    * config/i386/sse.md (<mask_codefor><code><mode>3<mask_name>):
    Remove wrong assert.
    (<floatsuffix>float<sseintvecmodelower><mode>2<mask_name><round_name>:
    Use <round_constraint> as operand 1 constraint.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN, will backport to release branches.

Uros.
