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...

Hi,   For a custom target, there is a pass to perform memory dependence analysis, where, i need to get memory pointer for "load instruction". I want to check the pointer alias behavior. I am getting this by considering the memoperands for the load instruction.   For "load instruction", Machine Instruction dumps as below:   vr12<def> = LD_Iri %vr2<kill>, 0;
