llvm dev - Oct 2010 - [LLVMdev] mapping virtual registers

Hello,

How can I map llvm variables (virtual registers) to their runtime locations 
(register/stack location)?

Thank you.

Regards,
Abbey.

Hello Abbey,

The SSA "registers" in LLVM don't map directly to a runtime
location.  The
easiest way to know where they go or come from is to use metadata to mark their 
locations at compile time.  Compiling with Clang using the debugger information 
intact should go a long way toward giving you what you need.

Hi Abbey,

in general you can't.  Perhaps you are really asking about debug info, in
which case see http://llvm.org/docs/SourceLevelDebugging.html
