Chris Lattner 731913bab3 Initial checkin of PRE on LLVM. This implementation is still lacking in ... several ways: * Load expressions are not PRE'd well. Alias Analysis should be used to get accurate information when computing anticipatibility. * The expression collection implementation does not handle PHI nodes properly, thus the implementation misses many opportunities to PRE. * This code could be sped up quite a bit Despite these flaws, the code seems to work well, and handles PR's as one would expect. llvm-svn: 5759		2003-03-31 19:55:43 +00:00
