When I first took a look ALPHA instruction description in
arm/isa/decoder.isa file, there are several different "format" for
different type of instructions.
While for ARM ISA, there is only one "format" named DataOp in the deocder
file, even worse I don't know where to find definition
like ArmMultAndMultAcc::armMultAndMultAcc() in the decoder file.
I must have missed something here. Any hint? Thanks
decode COND_CODE {
0xF: ArmUnconditional::armUnconditional();
default: decode ENCODING {
format DataOp {
0x0: decode SEVEN_AND_FOUR {
1: decode MISC_OPCODE {
0x9: decode PREPOST {
0: ArmMultAndMultAcc::armMultAndMultAcc();
