Machine Description Template?

2009-06-05 Thread Graham Reitz
Is there a machine description template in the gcc file source tree? If there is also template for the 'C header file of macro definitions' that would be good to know too. I did a file search for '.md' and there are tons of examples. Although, I was curious if there was a generic template

The trick past there is to compare the significant features of your machine with existing machines. For example, GCC prefers a 68000 style machine with a set of condition codes, however many machines only have one condition flag that changes meaning based on what you are doing. -- Michael 2009/
