988 I know it's complicated.
989 Basically there are two problems:
990 - determining the gaps between the Projs
991 - determining the biggest case constant to know the proj number for
993 I see several solutions:
994 1. Introduce a ProjDefault node. Solves both problems.
995 This means to extend all optimizations executed during construction.
996 2. Give the Cond node for switch two flavors:
997 a) there are no gaps in the Projs (existing flavor)
998 b) gaps may exist, default proj is still the Proj with the largest
999 projection number. This covers also the gaps.
1000 3. Fix the semantic of the Cond to that of 2b)
1002 Solution 2 seems to be the best:
1003 Computing the gaps in the Firm representation is not too hard, i.e.,
1004 libFIRM can implement a routine that transforms between the two
1005 flavours. This is also possible for 1) but 2) does not require to
1006 change any existing optimization.
1007 Further it should be far simpler to determine the biggest constant than
1008 to compute all gaps.
1009 I don't want to choose 3) as 2a) seems to have advantages for
1010 dataflow analysis and 3) does not allow to convert the representation to
