25 ;; ??? Should prepend a * to all pattern names which are not used.
26 ;; This will make the compiler smaller, and rebuilds after changes faster.
28 ;; ??? Should be enhanced to include support for many more GNU superoptimizer
29 ;; sequences. Especially the sequences for arithmetic right shifts.
31 ;; ??? Should check all DImode patterns for consistency and usefulness.
33 ;; ??? The MAC.W and MAC.L instructions are not supported. There is no
34 ;; way to generate them.
36 ;; ??? The cmp/str instruction is not supported. Perhaps it can be used
37 ;; for a str* inline function.
39 ;; BSR is not generated by the compiler proper, but when relaxing, it
40 ;; generates .uses pseudo-ops that allow linker relaxation to create
41 ;; BSR. This is actually implemented in bfd/{coff,elf32}-sh.c
