* Don't manually (and forcibly) run the verifier on the entire module fromChandler Carruth2014-07-301-4/+0
| | | | | | | | | | | | | the jump instruction table pass. First, the verifier is already built into all the tools. The test case is adapted to just run llvm-as demonstrating that we still catch the broken module. Second, the verifier is *extremely* slow. This was responsible for very significant compile time regressions. If you have deployed a Clang binary anywhere from r210280 to this commit, you really want to re-deploy. llvm-svn: 214287

* Add a new attribute called 'jumptable' that creates jump-instruction tables ↵Tom Roeder2014-06-051-0/+301
for functions marked with this attribute. It includes a pass that rewrites all indirect calls to jumptable functions to pass through these tables. This also adds backend support for generating the jump-instruction tables on ARM and X86. Note that since the jumptable attribute creates a second function pointer for a function, any function marked with jumptable must also be marked with unnamed_addr. llvm-svn: 210280
