New Revision: 222993
URL: http://llvm.org/viewvc/llvm-project?rev=222993&view=rev
Log:
Remove threshold for lifetime marker insertion of named temporaries
Now that TailRecursionElimination has been fixed with r222354, the
threshold on size for lifetime marker insertion can be removed. This
only affects named temporary though, as the patch for unnamed temporaries
is still in progress.
