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

[Richard Kenner]

    So any bi- or multi-arch configurations are then by definition both a
    cross and a regular compiler at the same time?  

Right, depending on the command line.

    Or how do they fit in your scheme?  

You bootstrap the native one and not the cross ones.  ;-)

    I never tried to "bootstrap" on x86_64 using --host=i686 --target=i686
    to build a 32bit compiler building 32bit 

Well, that's my point.  It's not really a bootstrap.  First you use the
cross-compiler to build a native compiler and *then* you bootstrap.
