[Bug bootstrap/30136] New: bootstrap fail for 4.3-20061209

[dcb314 at hotmail dot com]

I just tried to bootstrap gcc-4.3-20061209.

The compiler said

../../src/gcc-4.3-20061209/gcc/config/i386/sync.md:94: unknown mode
`<DCASHMODE>'
../../src/gcc-4.3-20061209/gcc/config/i386/sync.md:94: following context is `3
"register_operand" "b")'
make[3]: *** [s-mddeps] Error 1

This is on a x86_64 machine.

I have a memory that 4.3-20061202 also failed to bootstrap.

I know 4.3-20061225 was ok, so my best guess is that the problem
arrived between 20061225 and 20061202

Does this work now on the mainline?

The only access to mainline I have is
by the weekly snapshots.

I expect to try out 4.3-20061216.

Thus, answer expected Monday 18 Dec 2006.

I tried it out and it is still broken.

Is that three snapshots in a row
that fail on x86_64 ?

I have more detail.

I finally managed to get a working compiler
by removing all of the following flags from the
configure line

--disable-multilib
--with-cpu=opteron
--with-mpfr=/home/dcb/somewhere_else

I am not certain which one causes the problem,
but since the original crash occurs in the machine
description, I suspect that the --with-cpu=opteron
is causing the problem.

I can confirm this problem on recent snapshots as well (20070105 and 20070112).
I'm also on x86_64. Bootstrap fails with that same message.

Configuring GCC with:           
        --prefix=/usr           
        --bindir=/usr/x86_64-pc-linux-gnu/gcc-bin/4.3.98-alpha20070112

Agreed.

Snapshot 20010112 goes wrong and it's definately the flag
--with-cpu=opteron that causes the trouble.

Looks like a broken machine description to me, but I could
be wrong.

I got same result with --with-cpu=athlon64 on gcc-4.3-20070112 snapshot.
