to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

0x22000000 happens to be on the left of a heap allocation and the error
message is different (heap-buffer-overflow).
FreeBSD NetBSD have larger SHADOW_OFFSET (0x40000000) but let's try not
using #ifdef here.

Summary:
This patch (on top of the previous two (https://reviews.llvm.org/D40898 and
https://reviews.llvm.org/D40899) complete the compiler-rt side of the the Solaris
sanitizer port.
It contains the following sets of changes:
* For the time being, the port is for 32-bit x86 only, so reject the various tests on
x86_64.
* When compiling as C++, <setjmp.h> resp. <iso/setjmp_iso.h> only declares
_setjmp and _longjmp inside namespace std.
* MAP_FILE is a Windows feature. While e.g. Linux <sys/mman.h> provides a
no-op compat define, Solaris does not.
* test/asan/TestCases/Posix/coverage.cc was initially failing like this:
/vol/gcc/src/llvm/llvm/local/projects/compiler-rt/lib/sanitizer_common/scripts/sancov.py: 4 files merged; 2 PCs total
rm: cannot remove '/var/gcc/llvm/local/projects/compiler-rt/test/asan/I386SunOSConfig/TestCases/Posix/Output/coverage': Invalid argument
Further digging revealed that the rm was trying to remove the running test's working
directory which failed as observed. cd'ing out of the dir before let the test pass.
* Two tests needed a declaration of alloca. I've now copied the existing code from
test/asan/TestCases/alloca_constant_size.cc, but it may be more profitable and
maintainable to have a common testsuite header where such code is collected.
* Similarly, Solaris' printf %p format doesn't include the leading 0x.
* In test/asan/TestCases/malloc-no-intercept.c, I had to undef __EXTENSIONS__
(predefined by clang for no apparent reason) to avoid conflicting declarations
for memalign.
* test/ubsan/TestCases/Float/cast-overflow.cpp has different platform dependent
ways to define BYTE_ORDER and friends. Why not just use __BYTE_ORDER__ and
friends as predefined by clang and gcc?

Summary:
Include <stdarg.h> for variable argument list macros (va_list, va_start etc).
Add fallback definition of _LIBCPP_GET_C_LOCALE, this is required for
GNU libstdc++ compatibility. Define new macro SANITIZER_GET_C_LOCALE.
This value is currently required for FreeBSD and NetBSD for printf_l(3) tests.

These tests assume allocator_may_return_null=false
If allocator_may_return_null=true, gtest would not be able to switch it.
Tests needs to be re-implemented as lit tests.
llvm-svn: 308254
Summary:
Set proper errno code on alloction failures and change some
implementations to satisfy their man-specified requirements:
LSan: valloc and memalign
ASan: pvalloc, memalign and posix_memalign
Changing both allocators in one patch since LSan depends on ASan allocator in some configurations.

This test case occassionally hangs when run on powerpc. This is also a
problem on AArch64 (see https://bugs.llvm.org/show_bug.cgi?id=24389).
Reactivate this when the problem is fixed.
This could also be related to the same problem as with the tests
ThreadedOneSizeMallocStressTest, ThreadedMallocStressTest, and several
others that do not run reliably on powerpc.

Use the __SSE2__ to determine whether SSE2 is enabled in the ASAN tests
rather than relying on either of the __i686__ and __x86_64__. The former
is only set with explicit -march=i686, and therefore misses most of
the x86 CPUs that support SSE2. __SSE2__ is in turn defined if
the current settings (-march, -msse2) indicate that SSE2 is supported
which should be more reliable.

Summary:
The unittest is not working on windows. The "regexp.h" is not available and
gtest-port won't support regexp with operator '|'.
The test wasn't failing on 32-bits because of this check:
```
if (SANITIZER_WORDSIZE != 64 || ASAN_AVOID_EXPENSIVE_TESTS) return;
```
```

Since __builtin_setjmp has been fixed by rL267943, the test now works
on PowerPC. Enable it.
On the other hand, the SystemZ backend doesn't currently support
__builtin_setjmp. Disable it.

This test was in an infinite loop in AArch64. We're investigating it
on PR24389, but I'm disabling it for now, so that we continue testing
everything else.

__ANDROID__ is a define that comes from the toolchain when building
for Android targets. ANDROID has a different meaning. ANDROID is
defined for _every_ Android build, including those done for host
modules. For host modules, we want to build the regular Linux
sanitizers and builtins, not the one for Android devices. This hasn't
been a problem until now because we only just started building the
sanitizers for the host.
