Summary:
The changes allows building this file on NetBSD, mostly by
disabling the unsupported functions and adding OS-specific
system includes.

Summary:
Floating point division by zero or even undef does not have undefined
behavior and may occur due to optimizations.

Summary:
Changes:
- Don't attempt to intercept GLIBC specific functions like __strtol_internal.
This is required to stop intercepting it as we leak dlerror(3) for dlsym(3)
that cannot manage to find a symbol.
- Correct interception of fstatat(2).
- Don't run a test for fgetgrent_r() that is missing on NetBSD.
- Correct link_map location (offset) in Obj_Entry on x86_64 and i386.
- Stop intercepting getpshared-like functions in pthread(3). This is feature
is not enabled by default on NetBSD as it's unfinished.
- Switch intercepting from UTMP to UTMPX functions.

The test was not passing on targets where allocator_may_return_null
defaults to true. Change the test to a lit test so that we can test both
situations.

Summary:
CheckForPvallocOverflow was introduced with D35818 to detect when pvalloc
would wrap when rounding up to the next multiple of the page size.
Add this check to MSan's pvalloc implementation.
This time I made sure I was actually running (and writing) the correct tests,
and that they are passing...

Reverting D36093 until I can figure out how to launch the correct tests :/

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.
llvm-svn: 302887
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.

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.

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
Summary: Currently there is a libc++ test failing under MSAN because wcrtomb is not intercepted. This patch adds an interceptor for it.
