983 I know it's complicated.
984 Basically there are two problems:
985 - determining the gaps between the Projs
986 - determining the biggest case constant to know the proj number for
988 I see several solutions:
989 1. Introduce a ProjDefault node. Solves both problems.
990 This means to extend all optimizations executed during construction.
991 2. Give the Cond node for switch two flavors:
992 a) there are no gaps in the Projs (existing flavor)
993 b) gaps may exist, default proj is still the Proj with the largest
994 projection number. This covers also the gaps.
995 3. Fix the semantic of the Cond to that of 2b)
997 Solution 2 seems to be the best:
998 Computing the gaps in the Firm representation is not too hard, i.e.,
999 libFIRM can implement a routine that transforms between the two
1000 flavours. This is also possible for 1) but 2) does not require to
1001 change any existing optimization.
1002 Further it should be far simpler to determine the biggest constant than
1003 to compute all gaps.
1004 I don't want to choose 3) as 2a) seems to have advantages for
1005 dataflow analysis and 3) does not allow to convert the representation to
