case when the lookup table doesn't have any holes. This means we can build a lookup table for switches like this: switch (x) { case 0: return 1; case 1: return 2; case 2: return 3; case 3: return 4; default: exit(1); } The default case doesn't yield a constant result here, but that doesn't matter, since a default result is only necessary for filling holes in the lookup table, and this table doesn't have any holes. This makes us transform 505 more switches in a clang bootstrap, and shaves 164 KB off the resulting clang binary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199025 91177308-0d34-0410-b5e6-96231b3b80d8 |
