2017-08-30Add preliminary NetBSD support in libfuzzerKamil Rytarowski
Summary: This code already works and passes some number of tests. There is need to finish remaining sanitizers to get better coverage. Many tests fail due to overly long file names of executables (>31). This is a current shortcoming of the NetBSD 8(beta) kernel, as certain functions can fail (like retrieving file name of executable).

2017-08-29Minimal runtime for UBSan.Evgeniy Stepanov
Summary: An implementation of ubsan runtime library suitable for use in production. Minimal attack surface. * No stack traces. * Definitely no C++ demangling. * No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general. * as simple as possible Minimal CPU and RAM overhead. * Source locations unnecessary in the presence of (split) debug info. * Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at. * above two items save 3% binary size. When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.

2017-08-28Reland r311842 - [cmake] Remove i686 target that is duplicate to i386Michal Gorny
Remove the explicit i686 target that is completely duplicate to the i386 target, with the latter being used more commonly. 1. The runtime built for i686 will be identical to the one built for i386. 2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion on the clang end which has to expect either of them. 3. The checks are based on wrong assumption that __i686__ is defined for all newer x86 CPUs. In fact, it is only declared when -march=i686 is explicitly used. It is not available when a more specific (or newer) -march is used. Curious enough, if CFLAGS contain -march=i686, the runtime will be built both for i386 and i686. For any other value, only i386 variant will be built.

2017-08-24Add Clang dependency to the check for Clang C++ headers.George Karpenkov
The problem is that CMake is mostly imperative and the result of processing "if (TARGET blah)" checks depends on the order of import of CMake files. In this case, "projects" folder is registered before "tools", and calling "CheckClangHeaders" [renamed to have a better name] errors out without even giving Clang a chance to be built. This, in turn, leads to libFuzzer bot failures in some circumstances on some machines (depends on whether LIT or UNIT tests are scheduled first).

CMake's add_custom_target is considered to be *always* out of date. This patch changes it to a combination of add_custom_target and add_custom_command which actually tracks dependencies' timestamps.

2017-08-15[sanitizers CMake] NFC Refactor the logic for compiling and generating testsGeorge Karpenkov
into a function. Most CMake configuration under compiler-rt/lib/*/tests have almost-the-same-but-not-quite functions of the form add_X_[unit]tests for compiling and running the tests. Much of the logic is duplicated with minor variations across different sub-folders. This can harm productivity for multiple reasons: For newcomers, resulting CMake files are very large, hard to understand, and hide the intention of the code. Changes for enabling certain architectures end up being unnecessarily large, as they get duplicated across multiple folders. Adding new sub-projects requires more effort than it should, as a developer has to again copy-n-paste the configuration, and it's not even clear from which sub-project it should be copy-n-pasted. With this change the logic of compile-and-generate-a-set-of-tests is extracted into a function, which hopefully makes writing and reading CMake much easier.
