New Revision: 107143
URL: http://llvm.org/viewvc/llvm-project?rev=107143&view=rev
Log:
Delete assert in ComputeKeyFunction. The function runs fine without it, since
there's an explicit guard on isPolymorphic, and virtual bases don't affect the
key function calculation. This allows people to call
ASTContext::getKeyFunction on arbitrary classes.
