Craig Topper ef35532c13 [X86] Ignore bits 2:0 of the modrm byte when disassembling lfence, mfence, and sfence. ... These are documented as using modrm byte of 0xe8, 0xf0, and 0xf8 respectively. But hardware ignore bits 2:0. So 0xe9-0xef is treated the same as 0xe8. Similar for the other two. Fixing this required adding 8 new formats to the X86 instructions to convey this information. Could have gotten away with 3, but adding all 8 made for a more logical conversion from format to modrm encoding. I renumbered the format encodings to keep the register modrm formats grouped together.		2020-06-19 22:24:24 -07:00
