Herald added a project: LLVM.

Enabling shrink wrapping requires ensuring the insertion point of the epilogue is correct for MBBs without a terminator, in which case the instruction to adjust the stack pointer is the last instruction in the block.

This is a minimal work in progress patch, there are likely cases not covered by this.
