2066 The MODE argument is the machine mode for the MEM expression
2067 that wants to use this address.
2069 On the RS/6000, there are four valid address: a SYMBOL_REF that
2070 refers to a constant pool entry of an address (or the sum of it
2071 plus a constant), a short (16-bit signed) constant plus a register,
2072 the sum of two registers, or a register indirect, possibly with an
2073 auto-increment. For DFmode and DImode with a constant plus register,
2074 we must ensure that both words are addressable or PowerPC64 with offset
2077 For modes spanning multiple registers (DFmode in 32-bit GPRs,
2078 32-bit DImode, TImode), indexed addressing cannot be used because
2079 adjacent memory cells are accessed by adding word-sized offsets
2080 during assembly output. */
