internat compiler error

[Erik Meusel]

Hi,

compiling the new 2.4.11 kernel with gcc 3.0 resulted in an internal
compiler error. here is the minimal syntax causing the error:

gcc -D__KERNEL__ -I /home/scratch/linux-2.4.11/include/ -O2 -fomit-frame-pointer -c 8139too.c 

-O2 and -fomit-frame-pointer are important, without or with another
-O-Option, it doesn't happen.

the error is:
8139too.c: In function `netdev_ethtool_ioctl':
8139too.c:2419: Unrecognizable insn:

my gcc version is:

gcc -v
Reading specs from /opt/gcc/lib/gcc-lib/i686-pc-linux-gnu/3.0/specs
Configured with: ./configure --prefix=/opt/gcc
Thread model: single
gcc version 3.0

I will attach the sourcecode and the preprocessed file. (in gzip format,
I'm sorry about this, but my mail wouldn't be accepted being larger than
400kB)
