Thanks for the quick response.
You're right, since the if-conversion cleans the BB before deleting it
( "Remove labels and make stmts member of loop->header.").
Any way, does anyone see this problem in other passes, besides tree-if-conv?
Might be it's the only pass to expose this problem?
And also, why do we need to (pretty-)print empty BB?
I guess we can solve this problem either by changing this dump in pretty-print
(or in the tree-cfg dumps) or have another similar function of remove_bb (like
remove_empty_bb).
