* Some minor cleanups. No functionalitical change.Bill Wendling2011-07-281-17/+10
| | | | llvm-svn: 136341
* Leverage some of the code that John wrote to manage the landing pads.Bill Wendling2011-07-281-32/+56
| | | | | | | The new EH is more simple in many respects. Mainly, we don't have to worry about the "llvm.eh.exception" and "llvm.eh.selector" calls being in weird places. llvm-svn: 136339

* Initial stab at getting inlining working with the EH rewrite.Bill Wendling2011-07-281-10/+98
| | | | | | | | | This takes the new 'resume' instruction and turns it into a direct jump to the caller's landing pad code. The caller's landingpad instruction is merged with the landingpad instructions of the callee. This is a bit rough and makes some assumptions in how the code works. But it passes a simple test. llvm-svn: 136313

| | | | | | | | | | For -disable-iv-rewrite, perform LFTR without generating a new "canonical" induction variable. Instead find the "best" existing induction variable for use in the loop exit test and compute the final value of that IV for use in the new loop exit test. In short, convert to a simple eq/ne exit test as long as it's cheap to do so. llvm-svn: 135420
