From 79df8d2b3cbd67ac378aedc9414f1ddb0c3d96ef Mon Sep 17 00:00:00 2001 From: Dulma Rodriguez Date: Thu, 24 Sep 2015 16:17:04 -0100 Subject: [PATCH] [clang] Fix tests so that they pass with xcode 7 Summary: In the new clang the parameters to these functions have notnull annotations, because of that infer tests fail. More concretely, the tests say there would be a memory leak. In the symbolic execution of those functions though, an inconsistency is created, because the parameter was nil, and the constraint argument should not be nil was also there, which leads to an error in the execution and no object is created, hence, no memory leak. --- .../MemoryLeakExample.dot | 38 +++++++++---------- .../MemoryLeakExample.m | 8 ++-- infer/tests/endtoend/objc/MemoryLeakTest.java | 4 +- infer/tests/frontend/objc/BlockTest.java | 3 +- infer/tests/frontend/objc/NSAssertTest.java | 3 +- 5 files changed, 29 insertions(+), 27 deletions(-) diff --git a/infer/tests/codetoanalyze/objc/errors/memory_leaks_benchmark/MemoryLeakExample.dot b/infer/tests/codetoanalyze/objc/errors/memory_leaks_benchmark/MemoryLeakExample.dot index e0a01004f..0a548f735 100644 --- a/infer/tests/codetoanalyze/objc/errors/memory_leaks_benchmark/MemoryLeakExample.dot +++ b/infer/tests/codetoanalyze/objc/errors/memory_leaks_benchmark/MemoryLeakExample.dot @@ -1,9 +1,9 @@ digraph iCFG { -48 [label="48: DeclStmt \n n$34=_fun_FBColorCreateWithGray(0.000000:double ,0.300000:double ) [line 95]\n *&borderColor:struct CGColor *=n$34 [line 95]\n REMOVE_TEMPS(n$34);
