Hi,

I am doing a port in GCC 4.5.1.
The target supports storing immediate values into memory location
represented by a symbolic address. So in the move pattern i have given
constraints to represent this.

Presumably the target does not support storing an immediate value into other MEMs? ie, the only store-immediate is to a symbolic memory operand, right?

I think this is a case where you're going to need a secondary reload to force the immediate into a register if the destination is a non-symbolic MEM or a pseudo without a hard reg and its equivalent address is non-symbolic.
