Subject: Remove the language parameter and variable from the compile unit. We
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=7b87895a6c7307a0ee809659abdaefe4a48b6bc6;p=oota-llvm.git

Remove the language parameter and variable from the compile unit. We
can get it via the MDNode that's passed in. Save that instead.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189291 91177308-0d34-0410-b5e6-96231b3b80d8
