Hans Wennborg 09a31f3154 Allow switch-to-lookup table for tables with holes by adding bitmask check ... This allows us to generate table lookups for code such as: unsigned test(unsigned x) { switch (x) { case 100: return 0; case 101: return 1; case 103: return 2; case 105: return 3; case 107: return 4; case 109: return 5; case 110: return 6; default: return f(x); } } Since cases 102, 104, etc. are not constants, the lookup table has holes in those positions. We therefore guard the table lookup with a bitmask check.
