New Revision: 219314
URL: http://llvm.org/viewvc/llvm-project?rev=219314&view=rev
Log:
Remove bogus std::error_code returns form SectionRef.
There are two methods in SectionRef that can fail:
* getName: The index into the string table can be invalid.
* getContents: The section might point to invalid contents.
Every other method will always succeed and returning and std::error_code just
complicates the code. For example, a section can have an invalid alignment,
but if we are able to get to the section structure at all and create a
SectionRef, we will always be able to read that invalid alignment.
