Hi all
We are building GCC 4.1.2 cross toolchain for our custom processor in 64 bit
OS environment. Our custom processor is 32 bit. We faced with the following
ICE. This error did not come in 32 bit OS environment and toolchain build

Is there any changes needs to be done in backend w.r.t. 64 bit environment,
say, data structure layout etc?

Any hints will be very very appreciated.
Thanks all.
