 ;; ??? Should check all DImode patterns for consistency and usefulness.
 
-;; ??? Should add support for using BSR for short function calls.
-
 ;; ??? The MAC.W and MAC.L instructions are not supported.  There is no
 ;; way to generate them.
 
-;; ??? The BSR instruction is not supported.  It might be possible to
-;; generate it by keeping track of function sizes (and hence relative
-;; addresses), and then using it only if the target is earlier in the same
-;; file, and is within range.  Better would be assembler/linker relaxing,
-;; but that is much harder.
-
 ;; ??? The cmp/str instruction is not supported.  Perhaps it can be used
 ;; for a str* inline function.

+;; BSR.  This is actually implemented in bfd/{coff,elf32}-sh.c
