Ezgi Çiçek c80b80d0d7 [preanalysis] Handle closure substitution in conditionals ... Summary: Specialized closure substitution was broken for conditionals: ``` void foo(dispatch_block_t block1){ if (x){ block1(); // not replaced with specialized implementation } } ``` The problem was that when substituting function calls, it only used memory state at the exit node, rather than at each program point. We could solve this by - reverting the domain change in D24418560 (c47911359a), i.e. collecting all possible mappings conservatively (e.g. switch the domain back to `Map`) - pass the `invariant_map` for substitutions at each program point. We go with the second option here. The closure substitution is still somewhat broken as exemplified by the following example: ``` void foo(dispatch_block_t block1){ dispatch_block_t local_block = block1; local_block(); // we don't substitute the call here } ``` Reviewed By: skcho Differential Revision: D24993962 fbshipit-source-id: ebadddb58		4 years ago
