Hi, Is there a way to specify the Integer type to be of 2Byte for a Target? LLVM IR produces 4Bytes(i32) for Integer type. Clang can be tweaked to make the integer to be of 2Byte(i16), but is there a way to specify in the LLVM CodeGen? -- Thanks and Regards, Shashidhar

Hi, In the Table Gen format of defining Instructions for X86 architecture, some of the instruction patterns has both the dag expression "(implicit EFLAGS)" as well as the definition "Defs = [EFLAGS]". What is the difference between these two? Cant the Instruction Selector consider the Defs list when doing pattern match. I am confused when to use (implicit EFLAGS)

Hi, We have an architecture where the indirect move instruction implicitly increments the pointer value after the move. We have Instruction format and pattern for this type of instructions. How to encode the information that the pointer is incremented? Thanks and regards, Shashidhar

Hi Hal, Our Architecture has indirect move instruction which increments the pointer implicitly and the target only has i8 type values. So the load of i16 will be converted to two i8 target loads wherein after the first load instruction, the pointer to the first i8 address will automatically increment to point to the next i8 value. So the post increment nature is in the Target. A normal
