[llvm-commits] CVS: llvm/lib/Support/CommandLine.cpp

[Chris Lattner]

Changes in directory llvm/lib/Support:

CommandLine.cpp updated: 1.73 -> 1.74
---
Log message:

Add external definitions for commonly-used template specializations and add
anchor methods to others.  This eliminates the vtable/template method bloat
in .o files that defining a cl::opt used to impose (~4K per .o file for one
cp::opt<unsigned>).
