Status and rationale for toplevel bootstrap (was Re: Example of debugging GCC with toplevel bootstrap)

[Richard Kenner]

    It is most definitely neccessary that GCC produce the same code
    regardless of which compiler it is built with, assuming that the
    compiler it is built with is not itself buggy.

Of course, but that's not what we're talking about.

    A cross compiler and a native compiler targeting the same CPU chip,
    that's a different story.

But is the one we're talking about ...
