In short, you can't. Word-addressable memory is not currently
supported in LLVM (or Clang, for that

[LLVMdev] backend question
Hi All,
I am writing a backend for an architecture that has only 16-bit word addressing (No byte addresses ever. All data are always 16-bit).
How can I specify this in the backend?
As an example, consider the following instruction:
%arrayidx = getelementptr [129 x i16]* @flags, i16 0, i16 %i.043
When I generate assembler code, this now results in %i.043 being multiplied by 2 in the address
