Chris Lattner 6dc0ae2d18 Speed up the predicate used to decide when to inline by caching the size ... of callees between executions. On eon, in release mode, this changes the inliner from taking 11.5712s to taking 2.2066s. In debug mode, it went from taking 14.4148s to taking 7.0745s. In release mode, this is a 24.7% speedup of gccas, in debug mode, it's a total speedup of 11.7%. This also makes it slightly more aggressive. This could be because we are not judging the size of the functions quite as accurately as before. When we start looking at the performance of the generated code, this can be investigated further. llvm-svn: 8893		2003-10-06 15:52:43 +00:00
