   I'm using a powerpc-eabi compiler which I built from
   gcc-2.92.2 and binutils-2.9.1.  The assembler chokes on
   instructions like this one:

   li r5, 0xfffe

   initads.s:194: Error: operand out of range (65534 not between -32768 and 32767)                       


   It complains that the operand is out of range, when in fact,
   if should just translate the 0xfffe t0 -2.   Does anyone know if
   this is an assembler bug, or is it a feature?

It's a feature.  You're asking the assembler to load 0xfffe into r5.
That can't be done in one li instruction.  You can load 0xfffffffe,
but you can't load 0x0000fffe.

Did gcc generate that instruction?
