[llvm-commits] CVS: llvm/Makefile.rules

[Reid Spencer]

Changes in directory llvm:

Makefile.rules updated: 1.255 -> 1.256
---
Log message:

Implement the LLVM_DO_NOT_BUILD feature. If a file of  that name is
present in a directory that LLVM normally builds, it will skip building
the directory entirely. This is useful for allowing a bunch of projects to
live in the source tree but not be compiled from time to time.

Diffs of the changes:  (+12 -5)
