 That does not help me, I'm afraid, I can't trigger the issue with this 
piece of code alone.  It may be caused by a particular combination of GAS
command line options and `.set' directives.

 Since you can reproduce it, can you please send me the offending .s file 
(`make arch/mips/mm/sc-ip22.s') and the GAS invocation line used?  GCC 
will print the latter along all kinds of diagnostic stuff if -v is passed 
to an invocation involving assembly (e.g. `make V=1 CFLAGS_sc-ip22.o=-v 
arch/mips/mm/sc-ip22.o').  You can send me the whole diagnostics, I'll 
filter what I need.

 I think it'll be the most efficient way to move forward; otherwise I may 
keep missing the issue.

 Thanks,

  Maciej
