New Revision: 214209
URL: http://llvm.org/viewvc/llvm-project?rev=214209&view=rev
Log:
Move the bitcode error enum to the include directory.
This will let users in other libraries know which error occurred. In particular,
it will be possible to check if the parsing failed or if the file is not
bitcode.
