Re: Assembler message: "unsupported relocation type" with MPC555 crosscompiler

[Matthias Fertig <matthias dot fertig at ais dot fraunhofer dot de>]

i ran powerpc-eabi-gcc

	powerpc-eabi-gcc -g -S -mcpu=555 -I../../mpc555/include main.c

and looked into main.s


#231:	.LM18:
#232:		 mtspr EIE, r3 
#233:	.stabn 68,0,44,.LM19-main

the "move to special purpose register" looks good, for my opinion.

i don't understand the reason of the error? what does it mean, if there
is a problem with an allocaion type?

Thanks for ideas and comments,
Matthias
