llvm/lib/ExecutionEngine, branch release_26

Merge 80742 from mainline.

2009-09-04T18:42:45Z

Fix PR4845: r77946 completely broke x86_64 Darwin (or any situation where the desired triplet is a sub-target, e.g. thumbv7 vs. arm host). Reverting the patch isn't quite right either since the previous behavior does not allow the triplet to be overridden with -march. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_26@81023 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a bug where the DWARF emitter in the JIT was not initializing alignment

bytes. libgcc doesn't seem to mind, but if you pass this DWARF to GDB, it doesn't like it. Also make the JIT memory manager to initialize it's memory to garbage in debug mode, so that it's easier to find bugs like these in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79674 91177308-0d34-0410-b5e6-96231b3b80d8

SjLj based exception handling unwinding support. This patch is nasty, brutish

2009-08-11T00:09:57Z

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

To catch bugs like the one fixed in

2009-08-07T19:54:29Z

http://llvm.org/viewvc/llvm-project?view=rev&revision=78127, I'm changing the ExecutionEngine's global mappings to hold AssertingVH. That way, if unregistering a mapping fails to actually unregister it, we'll get an assert. Running the jit nightly tests didn't uncover any actual instances of the problem. This also uncovered the fact that AssertingVH didn't work, so I fixed that too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78400 91177308-0d34-0410-b5e6-96231b3b80d8
