* [OPENMP 4.1] Add 'threads' clause for '#pragma omp ordered'.Alexey Bataev2015-09-2510-23/+107
| | | | | | | | OpenMP 4.1 extends format of '#pragma omp ordered'. It adds 3 additional clauses: 'threads', 'simd' and 'depend'. If no clause is specified, the ordered construct behaves as if the threads clause had been specified. If the threads clause is specified, the threads in the team executing the loop region execute ordered regions sequentially in the order of the loop iterations. The loop region to which an ordered region without any clause or with a threads clause binds must have an ordered clause without the parameter specified on the corresponding loop directive. llvm-svn: 248569

* Recommit r248154: [ARM] Handle DSP feature as an ArchExtKindArtyom Skrobov2015-09-241-10/+8
| | | | | | | | | | | | | | | | Currently, the availability of DSP instructions (ACLE 6.4.7) is handled in a hand-rolled tricky condition block in lib/Basic/Targets.cpp, with a FIXME: attached. http://reviews.llvm.org/D12937 moved the handling of the DSP feature over to ARMTargetParser.def in LLVM, to be in line with other architecture extensions. This is the corresponding patch to clang, to clear the FIXME: and update the tests. Differential Revision: http://reviews.llvm.org/D12938 llvm-svn: 248521

* [analyzer] When memcpy'ing into a fixed-size array, do not invalidate entire ↵Devin Coughlin2015-09-242-9/+176
| | | | | | | | | | | | | | | | | | | | region. Change the analyzer's modeling of memcpy to be more precise when copying into fixed-size array fields. With this change, instead of invalidating the entire containing region the analyzer now invalidates only offsets for the array itself when it can show that the memcpy stays within the bounds of the array. This addresses false positive memory leak warnings of the kind reported by krzysztof in https://llvm.org/bugs/show_bug.cgi?id=22954 (This is the second attempt, now with assertion failures resolved.)

* [analyzer] Discard malloc-overflow bug-report when a known size is malloc'ed.Devin Coughlin2015-09-231-33/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch ignores malloc-overflow bug in two cases: Case1: x = a/b; where n < b malloc (x*n); Then x*n will not overflow. Case2: x = a; // when 'a' is a known value. malloc (x*n); Also replaced isa with dyn_cast. Reject multiplication by zero cases in MallocOverflowSecurityChecker Currently MallocOverflowSecurityChecker does not catch cases like: malloc(n * 0 * sizeof(int)); This patch rejects such cases. Two test cases added. malloc-overflow2.c has an example inspired from a code in linux kernel where the current checker flags a warning while it should not. A patch by Aditya Kumar!

* [darwin] [builtins] Stop generating cc_kext_ios5 and move iOS architectures ↵Chris Bieneman2015-09-231-5/+3
| | | | | | | | | | | | | | | | | out of cc_kext into cc_kext_ios Summary: This corresponds to a patch to compiler-rt (D13112). Xcode 7 doesn't support targeting iOS5 and earlier. Instead of just dropping cc_kext_ios5, I've repurposed it to cc_kext_ios, and I'm pulling the iOS architectures out of cc_kext. Putting OS X and iOS slices inside the same archive was just odd.

| | | | | | | | | | | | | | silently ignore them on arguments when they're provided indirectly (.e.g behind a template argument or typedef). This is mostly just good language design --- specifying that a generic argument is __weak doesn't actually do anything --- but it also prevents assertions when trying to apply a different ownership qualifier. rdar://21612439 llvm-svn: 248436

| | | | | | | | | | | when building a module. Clang already records the module signature when building a skeleton CU to reference a clang module.

* [analyzer] Make realloc(ptr, 0) handling equivalent to malloc(0).Devin Coughlin2015-09-221-13/+25
| | | | | | | | | | | | | | | | | | Currently realloc(ptr, 0) is treated as free() which seems to be not correct. C standard (N1570) establishes equivalent behavior for malloc(0) and realloc(ptr, 0): "7.22.3 Memory management functions calloc, malloc, realloc: If the size of the space requested is zero, the behavior is implementation-defined: either a null pointer is returned, or the behavior is as if the size were some nonzero value, except that the returned pointer shall not be used to access an object." The patch equalizes the processing of malloc(0) and realloc(ptr,0). The patch also enables unix.Malloc checker to detect references to zero-allocated memory returned by realloc(ptr,0) ("Use of zero-allocated memory" warning). A patch by Антон Ярцев!

| | | | | | | | | | | | | | | | | | | | Summary: `TypeTraitExpr`s are not supported by the ExprEngine today. Analyzer creates a sink, and aborts the block. Therefore, certain bugs that involve type traits intrinsics cannot be detected (see PR24710). This patch creates boolean `SVal`s for `TypeTraitExpr`s, which are evaluated by the compiler.
