...a hard time figuring out the relationship between my XXXAsmPrinter and MCAsmStreamer. Can someone explain what each is responsible for? Looking at the existing targets, the XXXAsmPrinter implementations seem to implement both the legacy "create a .s file" behavior, using printInstruction/printOperand/etc as well as the newer "lower to MCInst" behavior (EmitInstruction). Is this just a remnant of the v2.x -> v3.x transition? AFAICT, the MCAsmStreamer should be the interface to create the .s file going forward. Is that true? If true, how does it fit into registering the asmprinter a...

...ter, with operand modifiers. For example, on x86 there are instructions with ${dst:call} in their asm string. The "call" part is interpreted as an operand modifier. The assembly printer looks for the "call" modifier on MachineOperand::MO_Immediate operands (in X86ATTAsmPrinter::printOperand), which lets it perform custom printing for that type of operand. You could use a modifier which tells the AsmPrinter to print an immediate as the appropriate letter.

Hello, I am trying to create a machine instruction for "extractelement". I want to translate r <- extractelement v, 0 to mov r, v.x I was looking at the dag I can use and I found vector_extract. The inputs for this SDnode are a register and a iPtr constant. With that, I need to create 4 separate def's to extract element 0, 1, 2, and 3 and translate to v.x, v.y, v.z, and v.w. I

Dear all, I am looking to output assembly comments in my emitPrologue() function, just for my own readability. Searching for a way to do this found me this thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/043722.html, which says that the best way to output comments from somewhere like emitPrologue() is to: 1. Create an MDString for the comment. 2. Attach it to an LLVM
