I didn't worry about pipe asymmetries because the K6 integer pipes are
more similar than the Pentium pipes. For Pentium you may need to use
the MD_SCHED macros. See the discussions in the egcs list archive in
response to my request for comments on the original K6 patch. The
SPARC machine description has sample code.
