It does if you tell it to.  The "length" attribute must be managed
entirely by your backend.  Most backends with variable size branches
use the length attribute to select which branch insn to generate.  The
usual pattern is to call get_attr_length and use that to pick the
assembler instruction.  For example, jump_compact in sh.md.

Who wrote the backend that you are modifying?  Why can't you ask them?
