[cfe-commits] r164464 - /cfe/trunk/bindings/python/clang/cindex.py

[Dmitri Gribenko]

Author: gribozavr

New Revision: 164464

URL: http://llvm.org/viewvc/llvm-project?rev=164464&view=rev
Log:
Fix cindex.py compatibility with older libclang.so

The issue is that we were calling clang_getCompletionBriefComment
unconditionally.  New we check if this function is available before calling it.
