2017-08-29Shorten filenames of tests (-with-calls to -calls)Kamil Rytarowski
Summary: The NetBSD's 8(beta) versions of kernel functions to retrieve program name (vnode to path translator) and process memory map have internal limit of processing filenames with maximum of 31 characters. Filenames like Asan-x86_64-with-calls-Noinst-Test break this limit and affect tests. Rename "-with-calls" to "-calls". This changes fixes all issues for the Address Sanitizer test target (check-asan) on the current NetBSD support caused by long filenames.

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.

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.

2017-08-09[asan] Refactor thread creation bookkeepingVitaly Buka
Summary: This is a pure refactoring change. It paves the way for OS-specific implementations, such as Fuchsia's, that can do most of the per-thread bookkeeping work in the creator thread before the new thread actually starts. This model is simpler and cleaner, avoiding some race issues that the interceptor code for thread creation has to do for the existing OS-specific implementations.

2017-07-28[sanitizers] Sanitizer tests CMake clean up: try #2George Karpenkov
This patch addresses two issues: Most of the time, hacks with `if/else` in order to get support for multi-configuration builds are superfluous. The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it expands to `.` on all single-configuration builds, and to a configuration name otherwise. The `if/else` hacks for the library name generation should also not be done, as CMake has `TARGET_FILE` generator expression precisely for this purpose, as it expands to the exact filename of the resulting target.

This reverts commit 0ab44db2aa1cd3710355ad79b04f954ce68c0b3a. Fails on some bots, reverting until I can fix it. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@309318 91177308-0d34-0410-b5e6-96231b3b80d8
2017-07-27[sanitizers] Sanitizer tests CMake clean upGeorge Karpenkov
This patch addresses two issues: Most of the time, hacks with `if/else` in order to get support for multi-configuration builds are superfluous. The variable `CMAKE_CFG_INTDIR` was created precisely for this purpose: it expands to `.` on all single-configuration builds, and to a configuration name otherwise. The `if/else` hacks for the library name generation should also not be done, as CMake has `TARGET_FILE` generator expression precisely for this purpose, as it expands to the exact filename of the resulting target.

2017-07-26[sanitizer] Support libc++abi in addition to libstdc++Petr Hosek
This change adds sanitizer support for LLVM's libunwind and libc++abi as an alternative to libstdc++. This allows using the in tree version of libunwind and libc++abi which is useful when building a toolchain for different target.
