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

[Reid Spencer]

Changes in directory llvm:

Makefile.rules updated: 1.269 -> 1.270
---
Log message:

Add a "make spotless" rule for environments with BUILD_OBJ_ROOT not equal
to BUILD_OBJ_SRC. This will save the config.status and mklib files, then
wipe out the BUILD_OBJ_ROOT, copy back config.status and mklib, and then
run config.status to regenerate the makefiles. This target gives you a 
completely clean/fresh BUILD_OBJ_ROOT.
