Hello!
No need to go through all subreg processing, we already know we have
const_int here.
2016-02-09 Uros Bizjak <ubiz...@gmail.com>
* config/i386/i386.md (insv<mode>_1): Use gen_int_mode to
truncate const_int operand 1 to QImode.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32},
committed to mainline SVN.
Uros.
