* Completely rewrite 'correct' eh support. This changes how setjmp insertionChris Lattner2005-09-271-140/+301
| | | | | | | | | | | | | | | | | | is performed so it is only at most once per function that contains an invoke instead of once per invoke in the function. This patch has the following perks: 1. It fixes PR631, which complains about slowness. 2. If fixes PR240, which complains about non-volatile vars being live across setjmp/longjmps. 3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not forcing the jmpbufs to always be 8-bytes off the alignment of the structure. 4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us now about 4% faster than GCC. Further improvements are also possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23477 91177308-0d34-0410-b5e6-96231b3b80d8
