llvm dev - Sep 2009 - [LLVMdev] stackrestore

Hi,

is there a convenient way to get all allocations popped from the stack 
by llvm.stackrestore? Is this even decidable at compile time?

Thanks
Marc

Nope, you can (theoretically) have arbitrary control flow between the  
save and restore.  In practice, VLAs are very structured, so this only  
happens if the code has allocas mixed in with VLAs.
