New Revision: 47222

URL: http://llvm.org/viewvc/llvm-project?rev=47222&view=rev
Log:
Remove some code originally inspired by
expand_assignment in expr.c.  I don't think
this is needed, and I suspect it's not needed
in expand_assignment either and is just ancient
code that no-one bothered or dared to remove.
