2013-03-22ubsan: Pass floating-point arguments to the runtime by value if they fit theRichard Smith
value argument. If not, be sure we don't accidentally use a dynamic alloca. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177690 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20The flag "-coverage-function-names-in-data" is actually backwards -- we doNick Lewycky
emit function names in .gcda files by default, and the flag turns that off! Rename the flag to make it match what it actually does. This keeps the default format compatible with gcc 4.2. Also add a test for this flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177475 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-19PR15383: When -fsanitize=float-cast-overflow checks a float-to-int conversion,Richard Smith
it wasn't taking into account that the float should be truncated *before* the range check happens. Thus (unsigned)-0.99 and (unsigned char)255.9 have defined behavior and should not be trapped. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177362 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-03Improve C11 atomics support:David Chisnall
- Generate atomicrmw operations in most of the cases when it's sensible to do so. - Don't crash in several common cases (and hopefully don't crash in more of them). - Add some better tests. We now generate significantly better code for things like: _Atomic(int) x; ... x++; On MIPS, this now generates a 4-instruction ll/sc loop, where previously it generated about 30 instructions in two nested loops. On x86-64, we generate a single lock incl, instead of a lock cmpxchgl loop (one instruction instead of ten). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176420 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-26Unify clang/llvm attributes for asan/tsan/msan (Clang part)Kostya Serebryany
These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176076 91177308-0d34-0410-b5e6-96231b3b80d8
