// CHECK: landingpad { i8*, i32 }
Throw the switch to convert clang to the new exception handling model! This model uses the 'landingpad' instruction, which is pinned to the top of the landing pad. (A landing pad is defined as the destination of the unwind branch of an invoke instruction.) All of the information needed to generate the correct exception handling metadata during code generation is encoded into the landingpad instruction. The new 'resume' instruction takes the place of the llvm.eh.resume intrinsic call. It's lowered in much the same way as the intrinsic is. llvm-svn: 140049

Rewrite calls to bitcast unprototyped functions when emitting a definition. My variadics patch, r169588, changed these calls to typically be bitcasts rather than calls to a supposedly variadic function. This totally subverted a hack where we intentionally dropped excess arguments from such calls in order to appease the inliner and a "warning" from the optimizer. This patch extends the hack to also work with bitcasts, as well as teaching it to rewrite invokes. llvm-svn: 170034
