[LLVMdev] Writing a backend basic information
...ot
sure where/how best to cope with the immediate value printing and immediate
value limiting to 17bits in instruction selection/code generation.
I had thought of using a multiclass definition for each instruction that
has an immediate present/omitted. Would I need to define a new 17bit type
Imm17 in CodeGen/ValueTypes.td/h, or can I cope with the 17 bit immediate
elsewhere by perhaps using an i32? OR, can I handle this elsewhere in
codegen/instruction selection more elegantly? Apologies for the naivety of
my question.
