Pull in r216571 from upstream llvm trunk (by Zachary Turner):
|
|
|
|
|
|
|
|
|
|
Fix some semantic usability issues with DynamicLibrary.
|
|
|
|
|
|
|
|
|
|
This patch allows invalid DynamicLibrary instances to be
|
|
|
|
|
constructed, and fixes the const-correctness of the isValid()
|
|
|
|
|
method.
|
|
|
|
|
|
|
|
|
|
No functional change.
|
|
|
|
|
|
|
|
|
|
This is needed for supporting the upgrade to a newer LLDB snapshot.
