7// go run map.go -fmt=asm ../pp64.csv > asm.S
8// powerpc64le-linux-gnu-gcc -c asm.S -mcpu=power10 -mbig
9// powerpc64le-linux-gnu-objdump -d asm.o
10// to create the file decode_generated.txt used to verify the disassembler.
11//
12// Note, the golang disassembler is not expected to support every extended
13// mnemonic, but it should support those which frequently show up in object
14// files compiled by the golang toolchain.
