...d Imm:8> <-- maps to immed #8 <MCOperand Imm:14> <MCOperand Reg:0> Now, what are the two last operands (that are not actually present in disassembly)? And is it somehow possible to map the operands to OutOperandList/InOperandList found in the td definition? -- Vladimir Pouzanov http://www.farcaller.net/

Hi all. I came across a strange behaviour in the instruction printer for Thumbv2: The instruction is 0xf000b800, which is a b.w #0 LLVM returns it as b.w #-262144, which doesn't make any sense to me. Should I consider it a bug? -- Vladimir Pouzanov http://www.farcaller.net/

...e problem here, is it's ok to use llvm::MCAsmInfo objects, but as soon as I use it in the cast (e.g. to_ruby), I immediately get an undefined symbol __ZTIN4llvm9MCAsmInfoE. Similar symbols for other llvm classes are there in my library's .o file, this one does not.

Llvm typically doesn't build with RTTI enabled. Perhaps that's what you're running into?

...9; that MCInst has. The 'out' registers are always at the beginning of the list. You can also use getNumOperands().
