[llvm-commits] CVS: llvm/lib/System/SunOS/Path.cpp

[Reid Spencer]

Changes in directory llvm/lib/System/SunOS:

Path.cpp added (r1.1)
---
Log message:

Revise the design of the Path concept per peer review. Too many changes to
note individually but these essence of it is to not derive from 
std::string, clarify the interface, and provide better documentation.
There is now also (untested) implementations for AIX, Darwin, and SunOS.
