    PR124316: Fix ptwrite assembler mode

    Add explicit assembler mode for cases when the argument is not
    unambigious. This avoids cases where a user specified 64bit ptwrite
    ends up being 32bit due to an ambigious argument.

            PR target/124316

    gcc/ChangeLog:

            * config/i386/i386.md (ptwrite): Add explicit mode to
            instruction.

    gcc/testsuite/ChangeLog:

            * gcc.target/i386/pr124316.c: New test.
