        * expr.c (emit_move_resolve_push): Handle PRE_MODIFY
        and POST_MODIFY with CONST_INT adjustment equal to PUSH_ROUNDING.
        Fix POST_INC/POST_DEC handling if PUSH_ROUNDING is not identity.
        * config/i386/i386.md (pushhi2, pushqi2): Use pushl instead of pushw.
        Set mode to SI, adjust constraints.
        (pushhi2_rex64, pushqi2_rex64): Set mode to DI.
        * config/i386/i386.h (PUSH_ROUNDING): Round up to 4 instead of 2 for
        32-bit code.

        * gcc.target/i386/pr25293.c: New test.
