* [WebAssembly] Don't abort on code with UB.Dan Gohman2017-01-071-6/+17
| | | | | | | | Gracefully leave code that performs function-pointer bitcasts implying non-trivial pointer conversions alone, rather than aborting, since it's just undefined behavior. llvm-svn: 291326
* [WebAssembly] Move a SmallVector to a more specific scope. NFC.Dan Gohman2017-01-071-2/+2

* [WebAssembly] Add a pass to create wrappers for function bitcasts.Dan Gohman2017-01-071-0/+148
WebAssembly requires caller and callee signatures to match exactly. In LLVM, there are a variety of circumstances where signatures may be mismatched in practice, and one can bitcast a function address to another type to call it as that type. This patch adds a pass which replaces bitcasted function addresses with wrappers to replace the bitcasts. This doesn't catch everything, but it does match many common cases. llvm-svn: 291315
