Subject: Remove the LLVMBuildUnwind C API function.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=16005253850679a34b09a70bca32a6c0233380d6;p=oota-llvm.git

Remove the LLVMBuildUnwind C API function.

The 'unwind' function is going away with the new EH rewrite. This is step 0 in
keeping front-ends from using it.
