Re: GCC Status Report (2004-03-09)


    I've been suggesting things, and you've been implementing them, and then 
    not liking them for a couple of weeks now.

    Somehow, we've got to get a fix into the compiler.

    What do you suggest?

I have a suggestion, one that I think I made before:

There are two separate cases.

For the not-all-field-specified case, we *have* to do the clearing, but it's
relatively uncommon.  So if TARGET is /u, make a new temporary, do the store
into it in the usual manner, and copy it into the /u TARGET.

In the other cases (mostly_zero), the clearing is an *optimization*.  So
suppress it for the /u TARGET.
