Description

To begin with, will add support for 128-bit decimals. There are two parts :

1. llvm_generator needs to understand decimal types (value, precision, scale)
2. code decimal operations : add/subtract/multiply/divide/mod/..
   • This will be c++ code that can be pre-compiled to emit IR code
