[PATCH] D27680: [CodeGen] Move lifetime.start of a variable when goto jumps back past its declaration

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

Wouldn't it be simpler to just record an insertion point for the beginning of the current lexical scope and insert the lifetime.begin there instead of at the current IP?



================
Comment at: lib/CodeGen/CodeGenFunction.h:351
     llvm::Value *Size;
+    llvm::CallInst *LifetimeStart;
 
----------------
Addr and Size are recoverable from this.
