--- Comment #1 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
ghostman do you have a list of the scalar instructions supported?
i believe this is it
https://git.libre-soc.org/?p=binutils-gdb.git;a=blob;f=opcodes/ppc-opc.c;h=2db4f415413ea120483e817f0a8675f3aa3e6c8c;hb=5f4e0b013934af256dff12620886355a8aa3ab3d

btw an additional flag is needed

5094 #define SVP64       PPC_OPCODE_SVP64
5095 #define DRAFTSFFS   PPC_OPCODE_DRAFT_SFFS

and then all occurrences


    5250 {"maddedu",     VXA(4,  50),    VXA_MASK,    SVP64,     PPCVLE,       
 {RT, RA, RB, RC}},

replaced with

    5250 {"maddedu",     VXA(4,  50),    VXA_MASK,    DRAFTSFFS,     PPCVLE,   
     {RT, RA, RB, RC}},

i'll go through the list and add to optable.csv we can get a clear
picture about what's needed here.
