Confirmed, most likely caused by:
2004-03-23  Roger Sayle  <roger@eyesopen.com>

        * reg-stack.c (get_true_reg): Handle FLOAT_TRUNCATE like FLOAT_EXTEND
        if flag_unsafe_math_optimizations.
        * config/i386/i386.md (truncdfsf2): If flag_unsafe_math_optimizations
        and TARGET_80387 expand using truncdfsf2_noop pattern.
        (truncxfsf2): Likewise using truncxfsf2_noop.
        (truncxfdf2): Likewise using truncxfdf2_noop.
        (truncdfsf2_noop, truncxfsf2_noop, truncxfdf2_noop): New patterns.
