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

[Reid Spencer]

Changes in directory llvm/include/llvm/System:

DynamicLibrary.h updated: 1.2 -> 1.3
---
Log message:

Add in some methods for use by the JIT. LoadLibraryPermanently brings the
library into the address space permanently. SearchForAddressOfSymbol looks
in all previously permanently loaded libraries and any currently open 
libraries for a symbol, instead of just one library like GetAddressOfSymbol
