It's not a setting, I'm afraid. LLVM can assemble both upper & lower<br>
case instructions (as long as you're careful), but the underlying<br>
definition has to be in lower-case. The most obvious example of this<br>
is lib/MC/MCParser/AsmParser.cpp:2182 (in function parseStatement)<br>
where the mnemonic always gets "lower" called on it before it's handed<br>
off to the target.<br>
<br>
Cheers.<br>
