Re: libgloss/v850/crt0.S missing copy of .data from ROM to RAM?

No, crt0 is the right place for this code.

Obviously this problem has arisen because no-one thought about the 
possibility that the data sections might be loaded at a different
address from the their runtime locations.  It should be fairly 
straightforward to extend the assembler in crt0.S to support this
requirement however.  Would you like to submit a patch ?

Presumably there may also be a need to copy the .zdata, .tdata and
.sdata sections.  I also see that there is a .data1 section, although 
I do not know if it is ever used.
