* SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach2009-08-111-1/+38
| | | | | | | | | | | | | | and short. Well, it's kinda short. Definitely nasty and brutish. The front-end generates the register/unregister calls into the SjLj runtime, call-site indices and landing pad dispatch. The back end fills in the LSDA with the call-site information provided by the front end. Catch blocks are not yet implemented. Built on Darwin and verified no llvm-core "make check" regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78625 91177308-0d34-0410-b5e6-96231b3b80d8

* Add TargetRegistry::lookupTarget.Daniel Dunbar2009-07-261-0/+3
| | | | | | | | | | | | | | | - This is a simplified mechanism which just looks up a target based on the target triple, with a few additional flags. - Remove getClosestStaticTargetForModule, the moral equivalent is now: lookupTarget(Mod->getTargetTriple, true, false, ...); - This no longer does the fuzzy matching with target data (based on endianness and pointer width) that getClosestStaticTargetForModule was doing, but this was deemed unnecessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77111 91177308-0d34-0410-b5e6-96231b3b80d8
