Hi,
Since I want to compile GNAT on a new platform, for which I need
to use the native assembler (no cross-binutils), I want to do that
by creating the .s files for the Ada sources using a cross-compiler
and then do the rest of the bootstrap on the target platform.
This used to be simple, just configure and wait for an error due
to the missing compiler. Then copy the .s files and that's it.
But with the recent change to configure, it is not so easy anymore
to have configure do its job for the ada directory as well.
Are there any workarounds for this?

Which recent change, and what do you expect the configure to do?

Err, I'd expect it to be the same now, since the configure test
is for the *host* ada compiler, not the target ada compiler.

Yes, that is the issue. My host does not have an Ada compiler yet.
In order to get one, I want to configure GCC, including the ada
subdirectory, and then drop in the assembly files so no ada compiler
needs to be called. I can create the .s files, that's not the problem.

Oh. I wouldn't have done it that way, but I guess that works.
How about
ADAC=/bin/true GNATBIND=/bin/true ../src/configure --target=...

Set up a target as (if you choose the right name, it will just work),
and have it be a shell script that rcps (remote copies) the file to
the other machine, and then calls /bin/as (or whatever), and then
copies the results back, and then stores them in the right place.
I did this eons ago. Method should be sound and still work.
Otherwise -save-temps, and AS_FOR_TARGET=true!
If you get something that works for you, consider docing it in the
manual.

Then I'd also need to do a similar thing for ld,ar and ranlib probably.
If I can get this working, I'll add some docs...

Err, I'd expect it to be the same now, since the configure test

No, it's the target. The mechanism is this:
(1) Build a cross-compiler to the target.
(2) On the host, do "make stage1" and "make gnat-cross".
(3) On the target, bootstrap and install for just C.
(4) On the target, configure to build Ada and run "make" until it
fails.
(5) Copy .s files make in step (2) to the target and redo "make".
However, my suggestion is just to symlink a gnatgcc to be, e.g., /bin/true.
