 Modified Files:
 	src/external/gpl3/gcc/dist/gcc/config/vax: builtins.md predicates.md
 
 Log Message:
 Add new predicate volatile_mem_operand and use it for jbbssi<mode>
 
 Fixes PR port-vax/53039: GCC/VAX hits ICE building libstdc++
 
 GCC wants to change the label and then doesn't recognise the
 new insn, it believes it doesn't satisfy the memory_operand
 predicate.
 
 It appears the memory_operand predicate doesn't accept volatile
 memory accesses during the RTL generation phase.
 
 The predicate is from rs6000 code.
