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.

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.

Summary:
The build system was inconsistent in its naming conventions for
link flags. This patch changes all uses of LINKFLAGS to LINK_FLAGS,
for consistency with cmake's LINK_FLAGS property.
This patch should make it easier to search the source code for
uses of link flags, as well as providing the benefit of improved
style and consistency.

Instead of calling a sanitizer_common function, implement GetPageSize in the
test directly. MSan runtime does not export __sanitizer::* symbols, and the
current code breaks when the test and the runtime library are in the separate
link units (ex. when the test is built as a shared library).
llvm-svn: 266910
This breaks the valloc test on PowerPC, which has 64kiB pages. Since
getting page size portably is nontrivial, and there's already a function
for that in __sanitizer, just use it. Unfortunately, sanitizer_common.h
conflicts with the interface headers inclucded by msan_test.cc (and a few
of its own macros), so we have to declare it manually.

With COMPILER_RT_INCLUDE_TESTS turned ON and in a cross compiling
environment, the unit tests fail to link. This patch does the following changes
>Rename COMPILER_RT_TEST_CFLAGS to COMPILER_RT_UNITTEST_CFLAGS to reflect the
way it's used.
>Add COMPILER_RT_TEST_COMPILER_CFLAGS to COMPILER_RT_UNITTEST_CFLAGS so
that cross-compiler would be able to build/compile the unit tests
>Add COMPILER_RT_UNITTEST_LINKFLAGS to COMPILER_RT_UNITTEST_CFLAGS so
that cross-compiler would be able to link the unit tests (if needed)

This patch adds some fixes for MSAN with libc++ for aarch64:
1. Adds the libmsan_loadable name for aarch64.
2. Fixes some pthread_attr_setstacksize for aarch64, since glibc sets
the mininum stack size to be higher than the x86_64 default (16KB
vs 128KB).
3. Fixes a swprintf null char constant definition.
llvm-svn: 254015
CMake build rules listed -I flags for two different libc++ header
locations which broke when libc++ headers started using include_next.
Also change -I to -isystem to avoid compiler warning about
include_next.
llvm-svn: 249759
Summary: Currently there is a libc++ test failing under MSAN because wcrtomb is not intercepted. This patch adds an interceptor for it.

Summary:
Use CMake's cmake_parse_arguments() instead.
It's called in a slightly different way, but supports all our use cases.
It's in CMake 2.8.8, which is our minimum supported version.
CMake 3.0 doc (roughly the same. No direct link to 2.8.8 doc):
http://www.cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html?highlight=cmake_parse_arguments
Since I was already changing these calls, I changed ARCH and LIB into
ARCHS and LIBS to make it more clear that they're lists of arguments.
