Hi Im trying to add RISC V Store Instruction for an Experiment on my Target. The thing is, llvm Store Format gets Register and Pointer Type Operand. beside this, RISC-V Store Instruction takes source Register, Base Register and offset immediate type. So this takes 3 leafs. In this case, should I make new SelectionDAG Node in this case? or use BuildMI Instruction to add new Register? P.S.

...what the behavior should be and provide some tests before starting the implementation. The FileCheck-ified tests are attached to this email. They currently pass when using gcc to assemble the test. Here are the specific behaviors that are checked in the test: 1. Check that constants that fit into imm12 are converted to mov ldr r0, =0x3 2. Check that large constants are converted to ldr from constant pool ldr r0, =0x103 3. Duplicate constants should be merged to the same constant pool location ldr r0, =0x103 ... ldr r0, =0x103 4. A section defined in multiple pieces is merged a...
