* [analyzer] Re-enable using global regions as a symbolic base.Jordan Rose2013-04-151-2/+135
| | | | | | | | | | | | | | | | Now that we're invalidating global regions properly, we want to continue taking advantage of a particular optimization: if all global regions are invalidated together, we can represent the bindings of each region with a "derived region value" symbol. Essentially, this lazily links each global region with a single symbol created at invalidation time, rather than binding each region with a new symbolic value. We used to do this, but haven't been for a while; the previous commit re-enabled this code path, and this handles the fallout. <rdar://problem/13464044> llvm-svn: 179554
* [analyzer] Properly invalidate global regions on opaque function calls.Jordan Rose2013-04-151-7/+17
| | | | | | | | | | | | | | | | | | | | This fixes a regression where a call to a function we can't reason about would not actually invalidate global regions that had explicit bindings. void test_that_now_works() { globalInt = 42; clang_analyzer_eval(globalInt == 42); // expected-warning{{TRUE}} invalidateGlobals(); clang_analyzer_eval(globalInt == 42); // expected-warning{{UNKNOWN}} } This has probably been around since the initial "cluster" refactoring of RegionStore, if not longer. <rdar://problem/13464044> llvm-svn: 179553
* [analyzer] Don't invalidate globals when there's no call involved.Jordan Rose2013-03-201-2/+28
| | | | | | | | | | | | | | This fixes some mistaken condition logic in RegionStore that caused global variables to be invalidated when /any/ region was invalidated, rather than only as part of opaque function calls. This was only being used by CStringChecker, and so users will now see that strcpy() and friends do not invalidate global variables. Also, add a test case we don't handle properly: explicitly-assigned global variables aren't being invalidated by opaque calls. This is being tracked by <rdar://problem/13464044>. llvm-svn: 177572
* [analyzer] Handle reference parameters with default values.Jordan Rose2013-02-251-1/+8
| | | | | | | | | | | | r175026 added support for default values, but didn't take reference parameters into account, which expect the default argument to be an lvalue. Use createTemporaryRegionIfNeeded if we can evaluate the default expr as an rvalue but the expected result is an lvalue. Fixes the most recent report of PR12915. The original report predates default argument support, so that can't be it. llvm-svn: 176042
* [analyzer] Don't reinitialize static globals more than once along a pathAnna Zaks2013-02-071-0/+12
This patch makes sure that we do not reinitialize static globals when the function is called more than once along a path. The motivation is code with initialization patterns that rely on 2 static variables, where one of them has an initializer while the other does not. Currently, we reset the static variables with initializers on every visit to the function along a path. llvm-svn: 174676
