2018-02-24[ubsan-minimal] Fix the ubsan_minimal debug build (COMPILER_RT_DEBUG=1) on ↵Dan Liew
macOS. `ubsan_minimal` makes use of the `_sanitizer::atomic_load` function. This function uses the `DCHECK` macro which in debug builds will use the `_sanitizer::CheckFailed` function. This function is part of `sanitizer_common` but `ubsan_minimal` doesn't use this so the implementation is missing which leads to link failures on macOS when trying to link `libclang_rt.ubsan_minimal_osx_dynamic.dylib`. This is in contrast to the BFD linker on Linux which doesn't seem to care about the missing symbol. A basic implementation of `_sanitizer::CheckFailed` has been added to the `ubsan_minimal` debug build to avoid the link error. The implementation could definitely be improved but I don't know which functions can be used in this context so I decided to restrict myself to functions only being used in `ubsan_minimal` already. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@326032 91177308-0d34-0410-b5e6-96231b3b80d8

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.

2018-02-24[Sanitizers] Increase allocated chunk limit for LargeMmapAllocatorAlex Shlyapnikov
Summary: There are applications out there which allocate more than 1 << 18 large chunks of memory (those handled by LargeMmapAllocator, aka secondary allocator). For 64 bits, secondary allocator stores allocated chunks in a growing on demand region of memory, growing in blocks of 128K, up to 1 << 20 chunks total. Sanitizer internal allocator's secondary uses fixed size array storing up to 1 << 15 chunks (down to 256K from 2Mb of memory used for that array). Nothing is changed for 32 bits, chunks are still stored in the fixed size array (up to 1 << 15 chunks).

Summary: - Reland rL324263, this time allowing for a compile-time decision as to whether or not use the 32-bit division. A single test is using a class map covering a maximum size greater than 4GB, this can be checked via the template parameters, and allows SizeClassAllocator64PopulateFreeListOOM to pass; - `MaxCachedHint` is always called on a class id for which we have already computed the size, but we still recompute `Size(class_id)`. Change the prototype of the function to work on sizes instead of class ids. This also allows us to get rid of the `kBatchClassID` special case. Update the callers accordingly; - `InitCache` and `Drain` will start iterating at index 1: index 0 contents are unused and can safely be left to be 0. Plus we do not pay the cost of going through an `UNLIKELY` in `MaxCachedHint`, and touching memory that is otherwise not used; - `const` some variables in the areas modified; - Remove an spurious extra line at the end of a file.

2018-02-11[compiler-rt] Replace forkpty with posix_spawnKuba Mracek
On Darwin, we currently use forkpty to communicate with the "atos" symbolizer. There are several problems that fork or forkpty has, e.g. that after fork, interceptors are still active and this sometimes causes crashes or hangs. This is especially problematic for TSan, which uses interceptors for OS-provided locks and mutexes, and even Libc functions use those. This patch replaces forkpty with posix_spawn. Since posix_spawn doesn't fork (at least on Darwin), the interceptors are not a problem. Additionally, this also fixes a latent threading problem with ptsname (it's unsafe to use this function in multithreaded programs). Yet another benefit is that we'll handle post-fork failures (e.g. sandbox disallows "exec") gracefully now.

2018-02-08[builtins] Workaround for infinite recursion in c?zdi2Jonas Devlieghere
gcc resolves `__builtin_c?z` to `__c?zdi2` which leads to infinite recursion. This problem has been observed for sparc64, mips64 and riscv. Presumably this happens whenever an arch without dedicated bit counting instructions is targeted. This patch provides a workaround.

2018-02-08Update test counter_promo_nest.c to meet llvm changeSerguei Katkov
The test expects to see the pattern "load add store" twice in a row. However the test contains actually several instances of this pattern. Currently the first pattern appears in the output twice. But after LLVM change https://reviews.llvm.org/D42691 some addtional modification is done and one of another pattern has been hoisted in function entry block. As a result we have another order of meeting this pattern. The test is updated to meet this change. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@324571 91177308-0d34-0410-b5e6-96231b3b80d8
