Oh, right. When I think "cross compiler" I assume "for an embedded
target". Yes, two compilers with different $host but same $target
*should* (but currently don't) produce the same objects.
Two compilers with the same $host but different $target won't, even if
the two $targets are very similar.

No it isn't. The results should still be the same.
The question what is "native" here remains
I define "native" as meaning "the target and host configurations are
the same". So a biarch compiler can be either native or cross depending on
whether or not the target is the same as that used to build itself.
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.

The point of --disable-bootstrap is to disable bootstrapping. Th
BTW, did you capture the fact that BOOT_ADAFLAGS are no longer
passed with the new configure; make bootstrap ? FWIW, I can't really do
more testing or give more feedback on the new approach until this is
fixed.
I just verified that it works with --disable-bootstrap; make bootstrap.
As for bootstr

Then I'm confused: I thought the whole point of --disable-bootstrap is
to keep the old mechanism instead of getting the new one.
You will always have a bootstrap sequence and a non-bootstrap
sequence, but you'll need to reconfigure to switch between the two.

For the record,
So please, propose your usage case. Don't tell us which commands you expect
to be working, tell us of your workflow and why you think it's broken by the
new system. Probably it's just a misunderstanding, since there are no real
features that are being lost with the new system (while many bugs an

BTW, I assume someone is working on fixing the fact that currently
there is no simple way to know at which stage the bootstrap is,
while it was obvious with the previous approach:
stage1/xgcc -Bstage1/
That'd be great.

So the stage1 compiler is built as a 32-bit object, from the second
stage on they're built as 64-bit objects.
Very bad idea! I don't think we should support that.
The whole point of bootstrapping is that all of the stageN compilers should
behave identically and GCC simply doesn't do tha

To me, "bootstrap" means that all three compilers are identical in
configuration, so I don't follow your example.
I *suppose* you could include other parts of the toolchain in the "bootstrap",
but I think the advantages of doing so are pretty small.
What about libraries used by GCC? From the user point of view it is a
bad bug that you cannot bootstrap a 64-bit compiler starting from a
32-bit one (beca
Bootstrap, to me talks about the whole toolchain and all the library
that it uses.
I suppose it *can*, but that's not what term usually means.
Wouldn't you bootstrap an assembler written in assembly language?
Of course. But that's not relevant to this since we don't write the

I see it as "impossible with the old bootstrapping mechanism" as being
for a good reason: it's not part of the compiler! I still fail to understand
what it means to "bootstrap" anything other than a compiler: that word, to
me, talks only about compilers.
