Chandler Carruth 029cea90fa Revert r330742: Let TableGen write output only if it changed, instead of doing so in cmake. This change causes us to re-run tablegen for every single target on every single build. This is much, much worse than the problem being fixed AFAICT. On my system, it makes a clean rebuild of `llc` with nothing changed go from .5s to over 8s. On systems with less parallelism, slower file systems, or high process startup overhead this will be even more extreme. The only way I see this could be a win is in clean builds where we churn the filesystem. But I think incremental rebuild is more important, and so if we want to re-instate this, it needs to be done in a way that doesn't trigger constant re-runs of tablegen. llvm-svn: 331702		2018-05-07 23:41:48 +00:00
