instantiate_virtual_regs query

[Daniel Towner]

Hi all,

I am currently involved in writing a port of gcc for a new 16-bit embedded
RISC processor. I have defined a movhi instruction which takes the following
combinations (reg=reg, reg=imm, reg=mem, mem=reg). I am trying to compile
the following code fragment:

void fn(int a) {
int* p = &a;
}

The compiler generates an internal error in instantiate_virtual_regs - am I
missing a crucial instruction pattern?

Thanks,

Dan Towner.
