Re: [Sdcc-user] Internal Compiler Error

[Klaus F. <kla...@gm...>]

Hi,

it seems that the DS390/DS400 Port has a problem, when a function 
pointer is to be saved in a sloc.
In this case the operand type is set to immediate value (AOP_IMMD) 
instead of an pointer (AOP_DPTR).

I wrote a little patch that fixes this problem, but i'm not sure if i 
did it the right way.
Perhaps one of the developers could have a look at this.

Thanks,
Klaus

P.S.: Sorry for bad english
