[Qemu-devel] [PATCH v2 6/7] target/mips: Eliminate unreachable case for MSA instructions insert

[Mateja Marjanovic]

From: Mateja Marjanovic <mateja.marjano...@rt-rk.com>

The insert instruction doesn't support doublewords for
MIPS32 [2] (page 223), but MIPS64 supports doubleword [1] (page 224).

    Architecture Module

    Architecture Module
