|

// In big endian mode every memory access has an implicit byte swap. LDR and
|
|
// STR do a 64-bit byte swap, whereas LD1/ST1 do a byte swap per lane - that
|
|
// is, they treat the vector as a sequence of elements to be byte-swapped.

// The two pairs of instructions are fundamentally incompatible. We've decided

// to use LD1/ST1 only to simplify compiler implementation.
|
|
//
|

// LD1/ST1 perform the equivalent of a sequence of LDR/STR + REV. This makes

// v0 = load v2i32

// v3 = REV v4i16 v2 (implicit)
|

// store v4i16 v3
|
|
//
|
|
// But this is now broken - the value stored is different to the value loaded
|
|
// due to lane reordering. To fix this, on every BITCAST we must perform two
|
|
// other REVs:
|
|
// v0 = load v2i32
|
|
// v1 = REV v2i32 (implicit)
|
|
// v2 = REV v2i32
|

// v4 = REV v4i16
|
|
// v5 = REV v4i16 v4 (implicit)
|
|
// store v4i16 v5
|
|
//
|
|
// This means an extra two instructions, but actually in most cases the two REV
|
|
// instructions can be combined into one. For example:
|
|
// (REV64_2s (REV64_4h X)) === (REV32_4h X)
|
|
//
|
|
// There is also no 128-bit REV instruction. This must be synthesized with an
|
|
// EXT instruction.
|
|
//
|
|
// Most bitconverts require some sort of conversion. The only exceptions are:
|
|
// a) Identity conversions - vNfX <-> vNiX
|
|
// b) Single-lane-to-scalar - v1fX <-> fX or v1iX <-> iX
