is there a standard format in which we provide architecture specific information to a software

Hi All,
Our project requires us to specify architecture specific information to gcc(not .md files in gcc). We need to specify number of cycles taken per instruction for 686 architecture - as information to gcc.

Question: Is there a standard format in which we define the architecture specific information to softwares requiring these? Do we have the architecture specific information for Pentium Dual Core architecture in a format, that can be read by any software requiring it?

Target Architecture: 686 processor
Working on: Intel Pentium Dual Core processor

Thanking You,
Dhiraj.
