1.5i, 2.1i Map - A .mfp constraint for LOC'd FF is incorrecty overridden by "-pr b"

Product Line: FPGA Implementation
Product Part: map
Product Version: 1.5i
Problem Title:
1.5i, 2.1i Map - A .mfp constraint for LOC'd FF is incorrecty overridden by "-pr b"
Problem Description:
A FF that has been LOC'd via the floorplanner (.mfp) to a CLB site is
unexpectedly pulled into IOB site if -pr b option is used.
Solution 1:
This problem will be fixed in the first major release (as yet unnamed) after version 2.1i.
Meanwhile, IOB packing of registers can be controled by using IOB=TRUE/FALSE
attributes on the registers rather than using the map switch "-pr".
