<div dir="ltr"><div>Hello,<br></div><div><br></div><div>I'm just starting to work on a backend for a custom cpu. For some instructions this cpu has two flavors: first performs an operation, and the second performs an operation and updates condition codes (carry, zero, overflow, negative etc) based on the outcome. For example: add rd,rs instruction adds the contents of register rs to register rd and places the result in rd; add.cc rd, rs does the same and updates the condition codes. Can anybody point out an example of how such instructions should be defined in a corresponding xxInstrInfo.td file please?<br>
