Is the "type" attribute used by the platform-agnostic part of the backend?

No.

The only attribute used in machine independent code is the length attribute, which is used in the shorten branches code in final.c. Search for HAVE_ATTR_length in final.c.

All other attributes are only used in machine dependent code. Most commonly, they are used in other definitions in the md file, define_delay, instruction scheduling patterns, etc. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
