Hi all, I have a question about the types of MachineOperand. There are 12 different types of MachineOperand such as MO_Register, MO_Immediate and so on. Some of the names are self-explanatory such as MO_Register and MO_Immediate. Some of them are a little confusing such as MO_FrameIndex, MO_ConstantPoolIndex and so on. For example, what is the different between MO_ExternalSymbol and MO_GlobalAddress? Are these two types orthogona...

Hi,    I would like to get the type of immediate value (integer) from MachineOperand Class. Currently the immediate value is being represented as int64_t. int64_t ImmVal; // For MO_Immediate.   Is it possible to find out whether the immediate value is int8, 16, 32 etc?   Note: My target has a virtual Instruction set.   Thanks in advance, -Sanjay -------------- next part -------------- An HTML attachment was scrubbed...

...to do this is to handle this in the AsmPrinter, 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. Dan On May 5, 2009, at 10:23 PM, Manjunath Kudlur wrote: > Hello, > > I...

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
