That's what it actually means, and with 16-bit support it's going to be a little more relevant since in a few corner cases we may actually want to distinguish between 16-bit and 32-bit mode (for example the bare 'push' aliases to pushw/pushl etc.) Patch by David Woodhouse git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197768 91177308-0d34-0410-b5e6-96231b3b80d8
