(no filenames)

Building stage1 works, the stage1 compiler can build gnatlib, gnatttools,
rebuild itself, but the stage2 compiler cannot build gnatlib (gnat 031217
miscompiles itself?).

Tried two ways: native bootstrap using gnat-3.14, and crossbuild with
crosscompiler from x86-linux.

$ stage1/xgcc -Bstage1/ -v
Reading specs from stage1/specs
Configured with: ../configure --prefix=/opt/gnu-031218 --enable-languages=c,ada
--enable-haifa --with-gnu-ld --with-gnu-as mips-sgi-irix6.5
Thread model: single
gcc version 3.4 20031217 (experimental)

Using binutils-031218, mips-sgi-irix6.5, irix-6.5.21m, IP30

What GNAT version are you starting out with, there are some known bugs for mips with older Ada 
compilers, see PR 6669 and bug 6552?
In bug 6669, there is references to binaries which should work but do not overload his machine.
Can you try them and say if they work because the report in PR 6669 is that they work.

Sorry, pressed "send" to fast...

OK, I gave it two tries:

1) bootstrap native using gnat-3.14, which was in turn built from 3.13 <-- 3.12
<-- 3.11 (which is the last public binary)
This was very tedious, and fails as detailed in the bugreport.

2) build a crosscompiler, target mips-sgi-irix6.5, host x86/debian-3.0.
This is a new possibility, now that mips-sgi-irix6.5 is a binutils target.
I'm using gcc-3.3.2 + gnat as my x86 compiler to build the gcc-3.4-031218
snapshot cross(gcc+gnat), then use this to crossbuild the native
mips-sgi-irix6.5 gcc+gnat.
Then use this to bootstrap-build a native snapshot gcc compiler on irix.
This failed in the "native bootstrap" part, in the same location
(s-soflin.ads:145:4).

I'll give this a try.

I can confirm that gcc-3.4-20031217 can be bootstrapped with the gcc binary
mentioned above. I did configure it like that one, while my original (failed)
attempt was with GNU as/ld.

So, I will repeat once more to see if that was the cause of this faillure.
Meanwhile, the bug I filed can be canceled.

Thanks,
	Jan-Jaap
