We've been pretending that segments are i8imm since the initial support (r68645), predating the addition of the SEGMENT_REG class (r81895). That happens to works, but is wrong, and inconsistent with how we print (e.g., X86ATTInstPrinter::printMemReference) and parse them (e.g., X86Operand::addMemOperands). This change shouldn't affect any tool users, but is visible to library users or out-of-tree tablegen backends: this causes MCOperandInfo for the segment op to have an RC instead of "unknown", and TII::getRegClass to actually return something. As the registers are reserved and no vregs of the class ever created, that shouldn't change anything. No test change; no suspicious getRegClass() in X86 and CodeGen. llvm-svn: 271559 |
