[PATCH v4 0/5] target/sparc: Use explicit big-endian LD/ST API

Posted by Philippe Mathieu-Daudé 3 days, 5 hours ago

v4:
- Centralize sign-extension (clearly out of my comfort zone)
- Remove bswap in LD_code()

SPARC is big-endian. Use the explicit 'big'
endianness instead of the 'native' one.
Forbid further uses of legacy APIs.

Philippe Mathieu-Daudé (5):
  qemu/int128: Add int128_signextend()
  accel/tcg: Have cpu_ld*_mmu() methods consider the MO_SIGN flag
  target/sparc: Remove dubious swapping in LD_code() helper
  target/sparc: Replace MO_TE -> MO_BE
  configs/targets: Forbid SPARC to use legacy native endianness APIs
