Add `// run-pass` to collection of tests. 2018-09-04 10:05:53 +00:00			`// run-pass`
Review feedback: Added test with control flow merge of two borrows "before activation" In reality the currently generated MIR has at least one of the activations in a copy that occurs before the merge. But still, good to have a test, in anticipation of that potentially changing... 2017-12-14 22:30:05 +00:00
