Temporarily revert r257105 "[Verifier] Check that debug values have proper size" Looks like there's a case where clang generates debug info that triggers the new verifier check. Reverting while investigating. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@257107 91177308-0d34-0410-b5e6-96231b3b80d8 Keno Fischer 3 years ago
