According to the SPEC, The 5kc MIPS64 processor has a limited dual issue pipeline. However, the file comment header of 5k.md file in gcc/config/mips folder : ;; 5Kc - Single issue with no floating point unit. ;; 5kf - Separate floating point pipe which can dual-issue with the ;; integer pipe. So the 5kc is being implemented as a single issue pipeline and not a limited dual issue ? The generated code also seems to be for a single-issue pipeline. Is this true that the 5k implementation is a single-issue pipeline indeed ? Thanks
