Author: jbcoe Date: Tue Jan 17 14:03:54 2017 New Revision: 292247 URL: http://llvm.org/viewvc/llvm-project?rev=292247&view=rev Log: Fix Python 3 language issues and add an explicit check for Python version == 2.
Summary: Python bindings cannot support Python 3 without work being done to fix Unicode c-string conversion. This was attempted in https://reviews.llvm.org/D26082. That patch was reverted due to memory access issues on Linux. This revision fixes enough language compatibility issues for the clang module to be loaded and raise an error if the Python version is not 2.
