+ ///
+ /// The format of the textual pass pipeline description looks something like:
+ ///
+ /// module(function(instcombine,sroa),dce,cgscc(inliner,function(...)),...)
+ ///
+ /// Pass managers have ()s describing the nest structure of passes. All passes
+ /// are comma separated. As a special shortcut, if the very first pass is not
+ /// a module pass (as a module pass manager is), this will automatically form
+ /// the shortest stack of pass managers that allow inserting that first pass.
+ /// So, assuming function passes 'fpassN', CGSCC passes 'cgpassN', and loop passes
+ /// 'lpassN', all of these are valid:
+ ///
+ /// fpass1,fpass2,fpass3
+ /// cgpass1,cgpass2,cgpass3
+ /// lpass1,lpass2,lpass3
+ ///
+ /// And they are equivalent to the following (resp.):
+ ///
+ /// module(function(fpass1,fpass2,fpass3))
+ /// module(cgscc(cgpass1,cgpass2,cgpass3))
+ /// module(function(loop(lpass1,lpass2,lpass3)))
+ ///
+ /// This shortcut is especially useful for debugging and testing small pass
+ /// combinations. Note that these shortcuts don't introduce any other magic. If
+ /// the sequence of passes aren't all the exact same kind of pass, it will be
+ /// an error. You cannot mix different levels implicitly, you must explicitly
+ /// form a pass manager in which to nest passes.
