DEF_RTL_EXPR(ASM_OPERANDS, "asm_operands", "ssiEEsi", 'x')
/* A machine-specific operation.
1st operand is a vector of operands being used by the operation so that
any needed reloads can be done.
2nd operand is a unique value saying which of a number of machine-specific
operations is to be performed.
(Note that the vector must be the first operand because of the way that
genrecog.c record positions within an insn.)
This can occur all by itself in a PATTERN, as a component of a PARALLEL,
or inside an expression. */
