[PATCH 00/12] tcg: Factor hrev{32,64}_{i32,i64,tl} out

[Philippe Mathieu-Daudé]

This series factor the "byteswap each halfword within a
32/64-bit value" code duplication as generic helpers.

Modulo the documentation added, there is a good negative
diff-stat, so I believe this is a win from a maintainance
point of view.

I used "hrev" to follow the other bswap/hswap/rev helpers
but it isn't very descriptive, so any better name suggestion
is welcomed.
(In particular because there are other patterns I'd like to
factor out and then naming is getting worse, such 'wrev').

Philippe Mathieu-Daudé (12):
  tcg/tcg-op: Factor tcg_gen_hrev32_i32() out
  target/arm: Use generic hrev32_i32() in ARM REV16 and VREV16 opcodes
  target/cris: Use generic hrev32_i32() in SWAPB opcode
  target/rx: Use generic hrev32_i32() in REVW opcode
  tcg/tcg-op: Factor tcg_gen_hrev64_i64() out
  target/mips: Use generic hrev64_i64() in DSBH opcode
  target/ppc: Use generic hrev64_i64() in BRH / BSWAP16x8 opcodes
  target/loongarch: Use generic hrev64_i64() in REVB.4H opcode
  tcg/tcg-op: Add tcg_gen_hrev32_i64() and tcg_gen_hrev_i64()
  target/arm: Use generic hrev_i64() in Aarch64 REV16 opcode
  target/loongarch: Use generic hrev64_i32() in REVB.2H opcode
  target/mips: Use generic hrev32_tl() in WSBH opcode
