Dear all, I'm working on my a gcc compiler for my own written processor with the help of SimpleScalar. I want to remove "srav/slav" (immediate arithmetic shift) from the instruction set. I explore ss.md file but I didn't see any define_ins for the mentioned instructions, but they are used in other instruction definitions. It is also exist for addi/addui. Where I can find the definitions of these instructions? I want to force gcc to just use register shift and register add.
