[llvm-commits] CVS: llvm/lib/Bytecode/Reader/Reader.cpp

[Anton Korobeynikov]

Changes in directory llvm/lib/Bytecode/Reader:

Reader.cpp updated: 1.197 -> 1.198
---
Log message:

Adding dllimport, dllexport and external weak linkage types.
DLL* linkages got full (I hope) codegeneration support in C & both x86 
assembler backends.
External weak linkage added for future use, we don't provide any 
codegeneration, etc. support for it.
