This isn't necessary & with the next change to LLVM the DW_TAG_file_type entry won't be emitted at all - only the raw filename/directory pair, so match on that directly instead. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177609 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20Split ubsan runtime into three pieces (clang part):Richard Smith
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other sanitizer runtime is present. * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on a C++ ABI library, and is always linked in. * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a C++ ABI library, and is only linked in when linking a C++ binary. This change also switches us to using -whole-archive for the ubsan runtime (which is made possible by the above split), and switches us to only linking the sanitizer runtime into the main binary and not into DSOs (which is made possible by using -whole-archive). The motivation for this is to only link a single copy of sanitizer_common into any binary. This is becoming important now because we want to share more state between multiple sanitizers in the same process (for instance, we want a single shared output mutex). The Darwin ubsan runtime is unchanged; because we use a DSO there, we don't need this complexity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177605 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20[analyzer] Don't invalidate globals when there's no call involved.Jordan Rose
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>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177572 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20[analyzer] Track malloc'd memory into struct fields.Jordan Rose
Due to improper modelling of copy constructors (specifically, their const reference arguments), we were producing spurious leak warnings for allocated memory stored in structs. In order to silence this, we decided to consider storing into a struct to be the same as escaping. However, the previous commit has fixed this issue and we can now properly distinguish leaked memory that happens to be in a struct from a buffer that escapes within a struct wrapper. Originally applied in r161511, reverted in r174468. <rdar://problem/12945937> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177571 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20[analyzer] Invalidate regions indirectly accessible through const pointers.Jordan Rose
In this case, the value of 'x' may be changed after the call to indirectAccess: struct Wrapper { int *ptr; }; void indirectAccess(const Wrapper &w); void test() { int x = 42; Wrapper w = { x }; clang_analyzer_eval(x == 42); // TRUE indirectAccess(w); clang_analyzer_eval(x == 42); // UNKNOWN } This is important for modelling return-by-value objects in C++, to show that the contents of the struct are escaping in the return copy-constructor. <rdar://problem/13239826> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177570 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-20[analyzer] Remove strip of ElementRegion in CallEvent::invalidateRegions.Jordan Rose
This is a bit of old code trying to deal with the fact that functions that take pointers often use them to access an entire array via pointer arithmetic. However, RegionStore already conservatively assumes you can use pointer arithmetic to access any part of a region. Some day we may want to go back to handling this specifically for calls, but we can do that in the future. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177569 91177308-0d34-0410-b5e6-96231b3b80d8

For constructors/desctructors that return 'this', if there exists a callsite that returns 'this' and is immediately before the return instruction, make sure we are using the return value from the callsite. We don't need to keep 'this' alive through the callsite. It also enables optimizations in the backend, such as tail call optimization.
