retainAutoreleasedReturnValue that retains the returned value. This commit fixes a bug in ARC optimizer where it moves a release between a call and a retainAutoreleasedReturnValue, causing the returned object to be released before the retainAutoreleasedReturnValue can retain it. This commit accomplishes that by doing a lookahead and checking whether the call prevents the release from moving upwards. In the long term, we should treat the region between the retainAutoreleasedReturnValue and the call as a critical section and disallow moving anything there (possibly using operand bundles). rdar://problem/20449878 llvm-svn: 301724 |
