Hello! While looking in this area, I've noticed that there are constraints that allow wide immediate operands that result in unsupported immediate->memory moves on 64bit targets. Since these immediates have to be limited to 32bits, we have to use C constraint that allows only all-bits-zero 0.0 FP value. 2017-03-03 Uros Bizjak <ubizjak@gmail.com> * config/i386/i386.md (*pushtf): Change *roF constraint to *roC. (*pushxf): Limit oF constraint to 32bit targets and add oC constraint for 64bit targets. (pushxf splitter): Use PUSH_ROUNDING to calculate stack adjustment. (*pushdf): Change rmF constraint to rmC. Bootstrapped and regression tested on x86_64-linux-gnu {,-m32} and committed. Uros.
