[PATCH 00/11] tcg: Add revbit opcodes

Posted by Richard Henderson 1 month, 4 weeks ago

Adding these have been at the back of my mind for a while.  Most recently
tickled by the Octeon additions, and Anton's helper-to-tcg work.

I didn't add a 16-bit function or opcode because no host implements it.
The 16-bit reverse that the hexagon target does can be implemented with
a 32-bit reverse plus a shift.

  tcg: Fix opcode dump for bswap
  tcg: Add tcg_gen_revbit{32,64}
  target/arm: Use generic tcg_gen_revbit*
  target/loongarch: Use generic tcg_gen_revbit*
  target/loongarch: Expand bitswap inline
  target/mips: Expand octeon reflections inline
  tcg: Add revbit{32,64} opcodes
  tcg/optimize: Handle revbit{32,64}
  tcg/aarch64: Implement revbit{32,64}
  tcg/loongarch64: Import REVBIT insns
  tcg/loongarch64: Implement revbit{32,64}
