2017-05-12[msan] Remove a failing test from MemorySanitizer.ICmpRelationalAlexander Potapenko
This is a follow-up to r302787, which broke MemorySanitizer.ICmpRelational. MSan is now reporting a false positive on the following test case: TestForNotPoisoned((poisoned(-1, 0x80000000U) >= poisoned(-1, 0U))) , which is sort of anticipated, because we're approximating the comparison with an OR of the arguments' shadow values. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@302887 91177308-0d34-0410-b5e6-96231b3b80d8

2017-05-10[msan] Fix getmntent{_r} for empty /etc/fstabAdhemerval Zanella
Some configuration (for instance default docker ubuntu images) uses a default empty and invalid /etc/fstab configuration file. It makes any call to getmntent return NULL and it leads to failures on Msan-aarch64{-with-call}-Test/MemorySanitizer.getmntent{_r}. This patch fixes it by creating a temporary file with some valid entries (although not valid for the system) to use along with setmntent/getmntent. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@302639 91177308-0d34-0410-b5e6-96231b3b80d8

2016-09-15[compiler-rt] Do not introduce __sanitizer namespace globallyAnna Zaks
The definitions in sanitizer_common may conflict with definitions from system headers because: The runtime includes the system headers after the project headers (as per LLVM coding guidelines). lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

2016-08-26[CMake] Connect Compiler-RT targets to LLVM Runtimes directoryChris Bieneman
This patch builds on LLVM r279776. In this patch I've done some cleanup and abstracted three common steps runtime components have in their CMakeLists files, and added a fourth. The three steps I abstract are: (1) Add a top-level target (i.e asan, msan, ...) (2) Set the target properties for sorting files in IDE generators (3) Make the compiler-rt target depend on the top-level target The new step is to check if a command named "runtime_register_component" is defined, and to call it with the component name. The runtime_register_component command is defined in llvm/runtimes/CMakeLists.txt, and presently just adds the component to a list of sub-components, which later gets used to generate target mappings. With this patch a new workflow for runtimes builds is supported. The new workflow when building runtimes from the LLVM runtimes directory is: > cmake [...] > ninja runtimes-configure > ninja asan The "runtimes-configure" target builds all the dependencies for configuring the runtimes projects, and runs CMake on the runtimes projects. Running the runtimes CMake generates a list of targets to bind into the top-level CMake so subsequent build invocations will have access to some of Compiler-RT's targets through the top-level build. Note: This patch does exclude some top-level targets from compiler-rt libraries because they either don't install files (sanitizer_common), or don't have a cooresponding `check` target (stats). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279863 91177308-0d34-0410-b5e6-96231b3b80d8

This patch adds 48-bits VMA support for msan on aarch64. As current mappings for aarch64, 48-bit VMA also supports PIE executable. The 48-bits segments only cover the usual PIE/default segments plus some more segments (262144GB total, 0.39% total VMA). Memory avaliability can be increase by adding multiple application segments like 39 and 42 mapping (some mappings were added on this patch as well).
