5327,MPS ISA issue related to ll / sc,Oliver Kowalke <oliver.kowalke@…>,Peter Dimov,"boost/smart_ptr/detail/sp_counted_base_gcc_mips.hpp uses in its inline assembler ll/sc opcode for atomic operations (increment decremet).
Both opcodes are available since MIPS II ISA - unfortunately gcc assumes MIPS ISA I as default - so the inline assembler from sp_counted_base_gcc_mips.hpp triggers an assembler error:

'opcode not supported on this processor : mips1 (ll/sc)'

The header could be patches so that it instructs the CPU to switch to ISA II for ll/sc.
