[llvm-commits] CVS: llvm/runtime/GC/GCInterface.h Makefile gc_exported_symbols.lst

[Reid Spencer]

Changes in directory llvm/runtime/GC:

GCInterface.h updated: 1.5 -> 1.6
Makefile updated: 1.4 -> 1.5
gc_exported_symbols.lst updated: 1.2 -> 1.3
---
Log message:

Undo removal of the runtime libraries. While this may have been a bit
premature, these libraries will be going away for the 2.0 release. Other
arrangements for profiling, gc, etc. should be made in the next few months.
