Hello,
I try to locate a problem in GCSE pass and found some suspicious RTL
code as follows. Is it legitimate to have a "fallthru" succ edge but
next basic block is a different one?   Thanks. 

...
;; Succ edge 10 [91.5%] (fallthru)

;; Succ edge 9 [8.5%] 

;; Start of basic block ( 8) -> 9
...


Cheers,
Bingfeng Mei

Yes, this is valid if you are in cfglayout mode.
