6706//
6707// Consider a simple memory load followed by a bitconvert then a store.
6708//   v0 = load v2i32
6709//   v1 = BITCAST v2i32 v0 to v4i16
6710//        store v4i16 v2
6711//
6712// In big endian mode every memory access has an implicit byte swap. LDR and
6713// STR do a 64-bit byte swap, whereas LD1/ST1 do a byte swap per lane - that
6714// is, they treat the vector as a sequence of elements to be byte-swapped.
6715// The two pairs of instructions are fundamentally incompatible. We've decided
6716// to use LD1/ST1 only to simplify compiler implementation.
6717//
6718// LD1/ST1 perform the equivalent of a sequence of LDR/STR + REV. This makes
6719// the original code sequence:
6720//   v0 = load v2i32
6721//   v1 = REV v2i32                  (implicit)
6722//   v2 = BITCAST v2i32 v1 to v4i16
6723//   v3 = REV v4i16 v2               (implicit)
6724//        store v4i16 v3
6725//
6726// But this is now broken - the value stored is different to the value loaded
6727// due to lane reordering. To fix this, on every BITCAST we must perform two
6728// other REVs:
6729//   v0 = load v2i32
6730//   v1 = REV v2i32                  (implicit)
6731//   v2 = REV v2i32
6732//   v3 = BITCAST v2i32 v2 to v4i16
6733//   v4 = REV v4i16
6734//   v5 = REV v4i16 v4               (implicit)
6735//        store v4i16 v5
6736//
6737// This means an extra two instructions, but actually in most cases the two REV
6738// instructions can be combined into one. For example:
6739//   (REV64_2s (REV64_4h X)) === (REV32_4h X)
6740//
6741// There is also no 128-bit REV instruction. This must be synthesized with an
6742// EXT instruction.
6743//
