[LLVMdev] Placeholders in the target data layout

so is the native linker, presumably.  What are you trying to do exactly?

You can simply not provide a target layout initially, and add it when you are
about to do something target specific (see setDataLayout and setTargetTriple
in Module.h).

Ciao, Duncan.
