[Capstone-users] new ARM instructions

[Mahesh M. <ma...@am...>]

Hi!

I pulled down the latest version of cstool (4.0.2) and tried to decode some new instructions, and ran into trouble:

./cstool arm64be d69f0bff,4e5c0c78,4e5b0c55,f820303f,b8e0003e,88fe7e62
ERROR: invalid assembly code

I tried arm64 and armv8 as the arch+mode but that didn’t help.

Here is how a recent version of GNU objdump disassembles these bytes.

d69f0bff    eretaa
4e5c0c78    fmla    v24.8h, v3.8h, v28.8h
4e5b0c55    fmla    v21.8h, v2.8h, v27.8h
f820303f    stset   x0, [x1]
b8e0003e    ldaddal w0, w30, [x1]
88fe7e62    casa    w30, w2, [x19]

Am I doing something wrong in my cstool incantations? If not, what is the best way to request the newer ARM ISAs for capstone? I would very much appreciate  the additions. Thank you kindly for your time.

Thanks so much,
Mahesh
