[PATCH v2 8/8] target/ppc: Move logical fixed-point instructions to deco


From: Chinmay Rath
Subject: [PATCH v2 8/8] target/ppc: Move logical fixed-point instructions to decodetree.
Date: Tue, 23 Apr 2024 12:02:34 +0530

Moving the below instructions to decodetree specification :

        andi[s]., {ori, xori}[s]                        : D-form

        {and, andc, nand, or, orc, nor, xor, eqv}[.],
        exts{b, h, w}[.],  cnt{l, t}z{w, d}[.],
        popcnt{b, w, d},  prty{w, d}, cmp, bpermd       : X-form

With this patch, all the fixed-point logical instructions have been
moved to decodetree.
The changes were verified by validating that the tcg ops generated by those
instructions remain the same, which were captured with the '-d in_asm,op' flag.
