* LSR should avoid redundant edge splitting.Andrew Trick2011-10-044-6/+55
| | | | | | | | This handles the case in which LSR rewrites an IV user that is a phi and splits critical edges originating from a switch. Fixes <rdar://problem/6453893> LSR is not splitting edges "nicely" llvm-svn: 141059

* Check-pointing the new SjLj EH lowering.Bill Wendling2011-10-032-0/+77
| | | | | | | | | | | This code will replace the version in ARMAsmPrinter.cpp. It creates a new machine basic block, which is the dispatch for the return from a longjmp call. It then shoves the address of that machine basic block into the correct place in the function context so that the EH runtime will jump to it directly instead of having to go through a compare-and-jump-to-the-dispatch bit. This should be more efficient in the common case. llvm-svn: 141031
