[LLVMdev] Debug info for variables when optimizing

[Chris Lattner]

Hi All,

Right now, mem2reg and SRoA strip all debug information off allocas  
they promote.  This means that we lose almost all debug information  
for local variables when the optimizer is turned on.  Here is a  
proposal to improve the situation:

Thoughts welcome,
