Hans Wennborg 4744ac1733 Switch-to-lookup tables: set threshold to 3 cases ... There has been an old FIXME to find the right cut-off for when it's worth analyzing and potentially transforming a switch to a lookup table. The switches always have two or more cases. I could not measure any speed-up by transforming a switch with two cases. A switch with three cases gets a nice speed-up, and I couldn't measure any compile-time regression, so I think this is the right threshold. In a Clang self-host, this causes 480 new switches to be transformed, and reduces the final binary size with 8 KB. llvm-svn: 199294		2014-01-15 05:00:27 +00:00
