[Qemu-devel] [PATCH v2 0/7] target/mips: Add support for MSA instructions on a big endian host

[Mateja Marjanovic]

From: Mateja Marjanovic <address@hidden>

While working on adding support for big endian hosts on QEMU for the
MSA instructions copy_u, copy_s and insert, I noticed there was some
unreachable code (copy_u.d doesn't exist), and some unnecessary code
(for instance, insert supports doublewords only on MIPS64)

v2:
 - Eliminate unreachable code in copy_u
 - Add preprocessing conditionals (if host is MIPS64, check that case)
   in copy_u, insert, fill. 

Mateja Marjanovic (7):
  target/mips: Fix <ld|st>.<b|h|w|d> MSA instructions for MIPS big
    endian host
  target/mips: Fix copy_s.<b|h|w> for MIPS big endian host
  target/mips: Fix copy_u.<b|h|w> for MIPS big endian host
  target/mips: Fix insert.<b|h|w> for MIPS big endian host
  target/mips: Eliminate unreachable case for MSA instructions copy_u
  target/mips: Eliminate unreachable case for MSA instructions insert
  target/mips: Eliminate unreachable case for MSA instructions fill
