MIPS HI16 relocation problem with split addresses

[Mark Rustad]

Folks,

I have found a MIPS HI16 relocation problem with binutils-2.13.1. The 
problem shows up when combining objects as follows:

address@hidden 553$ mips-ld -r -o xxx.o fails.o
mips-ld: final link failed: Bad value

I tracked this down to a function that ends with an lui instruction, 
thereby having a R_MIPS_HI16 relocation. It appears that code in 
bfd/elfxx-mips.c expects that there must be a matching LO16 relocation 
following the HI16, but in this case, the matching LO16 comes before 
the HI16.

I have attached a somewhat stripped-down assembly source that 
demonstrates the problem. For now, I can work around this issue by 
passing -mno-split-addresses to GCC to avoid generating sequences like 
this.
