[llvm-commits] CVS: llvm/lib/System/Unix/MappedFile.inc

[Reid Spencer]

Changes in directory llvm/lib/System/Unix:

MappedFile.inc updated: 1.18 -> 1.19
---
Log message:

Use the stat information in the Path object, if it is already obtained. This
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.
