[llvm-commits] CVS: llvm/include/llvm/System/Path.h

[Reid Spencer]

Changes in directory llvm/include/llvm/System:

Path.h updated: 1.17 -> 1.18
---
Log message:

Fix a file overwrite bug in llvm-ar introduced by changes to 
createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.
