2005-09-27Avoid spilling stack slots... to stack slots.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23478 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-27Completely rewrite 'correct' eh support. This changes how setjmp insertionChris Lattner
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
