2018-07-10[compiler-rt] Get rid of "%T" expansionsFilipe Cabecinhas
Summary: Original patch by Kuba Mracek The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in compiler-rt.

2018-06-20[sanitizer] Unify and generalize Apple platforms in CMake and lit test configsKuba Mracek
There's more platforms than just "ios" and "iossim" that we should support, and adding more lit config variables for each platform isn't great. Let's generalize and have a single value that determines what the platform under test is.

2018-06-18[TSan] Report proper error on allocator failures instead of CHECK(0)-ingAlex Shlyapnikov
Summary: Following up on and complementing D44404 and other sanitizer allocators. Currently many allocator specific errors (OOM, for example) are reported as a text message and CHECK(0) termination, no stack, no details, not too helpful nor informative. To improve the situation, detailed and structured common errors were defined and reported under the appropriate conditions. Common tests were generalized a bit to cover a slightly different TSan stack reporting format, extended to verify errno value and returned pointer value check is now explicit to facilitate debugging.

2018-02-24Correct ctype(3) functions with NLS on NetBSDKamil Rytarowski
Summary: The setlocale(3) function reloads the ctype(3) arrays from external files. This happens behind the scenes in the internals of libc (citrus library, runes functions etc). ctype(3) functions like isspace(3) can be provided with two variations on NetBSD: inlined or via a global symbol in libc: ``` #if defined(_NETBSD_SOURCE) && !defined(_CTYPE_NOINLINE) && \ !defined(__cplusplus) #include <sys/ctype_inline.h> #else #include <sys/ctype_bits.h> #endif ``` The in-lined versions are de-facto array lookup operations. ``` #define isspace(c) ((int)((_ctype_tab_ + 1)[(c)] & _CTYPE_S)) ``` After setting setlocale(3) the ctype(3) arrays (_ctype_tab_, _toupper_tab_, _tolower_tab_) are reload behind the scenes and they are required to be marked as initialized. Set them initialized inside the common setlocale(3) interceptor. The arrays are of size of 257 elements: 0..255 + 1 (EOF). This corrects errors on NetBSD/amd64 in applications prebuilt with MSan.
