| // Conversions within AdvSIMD types in the same register size are free. |
| // But because we need a consistent lane ordering, in big endian many |
| // conversions require one or more REV instructions. |
| // |
| // Consider a simple memory load followed by a bitconvert then a store. |
| // v0 = load v2i32 |
| // v1 = BITCAST v2i32 v0 to v4i16 |
| // store v4i16 v2 |
| // |
| // 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 |
| // the original code sequence: |
| // v0 = load v2i32 |
| // v1 = REV v2i32 (implicit) |
| // v2 = BITCAST v2i32 v1 to v4i16 |
| // 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 |
| // v3 = BITCAST v2i32 v2 to v4i16 |
| // 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 |
