platforms. Attempt #3.
The main problem here is that `-*-version_min=` was not being passed to
the compiler when building test cases. This can cause problems when
testing on devices running older OSs because Clang would previously
assume the minimum deployment target is the the latest OS in the SDK
which could be much newer than what the device is running.
Previously the generated value looked like this:
`-arch arm64 -isysroot
<path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk`
With this change it now looks like:
`-arch arm64 -stdlib=libc++ -miphoneos-version-min=8.0 -isysroot
<path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk`
This mirrors the setting of config.target_cflags on macOS.
This change is made for ASan, LibFuzzer, TSan, and UBSan.
To implement this a new `get_test_cflags_for_apple_platform()` function
has been added that when given an Apple platform name and architecture
returns a string containing the C compiler flags to use when building
tests. This also calls a new helper function `is_valid_apple_platform()`
that validates Apple platform names.
This is the third attempt at landing the patch.
The first attempt (r359305) had to be reverted (r359327) due to a buildbot
failure. The problem was that calling `get_test_cflags_for_apple_platform()`
can trigger a CMake error if the provided architecture is not supported by the
current CMake configuration. Previously, this could be triggered by passing
`-DCOMPILER_RT_ENABLE_IOS=OFF` to CMake. The root cause is that we were
generating test configurations for a list of architectures without checking if
the relevant Sanitizer actually supported that architecture. We now intersect
the list of architectures for an Apple platform with
`<SANITIZER>_SUPPORTED_ARCH` (where `<SANITIZER>` is a Sanitizer name) to
iterate through the correct list of architectures.
The second attempt (r363633) had to be reverted (r363779) due to a build
failure. The failed build was using a modified Apple toolchain where the iOS
simulator SDK was missing. This exposed a bug in the existing UBSan test
generation code where it was assumed that `COMPILER_RT_ENABLE_IOS` implied that
the toolchain supported both iOS and the iOS simulator. This is not true. This
has been fixed by using the list `SANITIZER_COMMON_SUPPORTED_OS` for the list
of supported Apple platforms for UBSan. For consistency with the other
Sanitizers we also now intersect the list of architectures with
UBSAN_SUPPORTED_ARCH.

This patch enables compiler-rt on SPARC targets. Most of the changes are straightforward:
- Add 32 and 64-bit sparc to compiler-rt
- lib/builtins/fp_lib.h needed to check if the int128_t and uint128_t types exist (which they don't on sparc)
There's one issue of note: many asan tests fail to compile on Solaris/SPARC:
fatal error: error in backend: Function "_ZN7testing8internal16BoolFromGTestEnvEPKcb": over-aligned dynamic alloca not supported.
Therefore, while asan is still built, both asan and ubsan-with-asan testing is disabled. The
goal is to check if asan keeps compiling on Solaris/SPARC. This serves asan in gcc,
which doesn't have the problem above and works just fine.
With this patch, sparcv9-sun-solaris2.11 test results are pretty good:
Failing Tests (9):
Builtins-sparc-sunos :: divtc3_test.c
Builtins-sparcv9-sunos :: compiler_rt_logbl_test.c

The builtin failures are due to Bugs 42493 and 42496. The tree contained a few additonal
patches either currently in review or about to be submitted.

Unlike asan, which isn't supported yet on 64-bit Solaris/x86, there's no reason to disable
ubsan. This patch does that, but keeps the 64-bit ubsan-with-asan tests disabled.

These lit configuration files are really Python source code. Using the
.py file extension helps editors and tools use the correct language
mode. LLVM and Clang already use this convention for lit configuration,
this change simply applies it to all of compiler-rt.

In particular, don't call get_target_flags_for_arch() since that
will cause an error in some situations:
If DARWIN_iossim_ARCHS=i386;x86_64, DARWIN_osx_ARCHS=x86_64, and
DARWIN_iossym_SYSROOT isn't set (due to the simulator sysroot not being
available), then config-ix.cmake won't add i386 to COMPILER_RT_SUPPORTED_ARCH
but ubsan's test/CMakeLists.txt would call get_target_flags_for_arch()
with i386, which would then run into the error in
get_target_flags_for_arch().
Having these conditions isn't ideal. The background here is that we
configure our mac-hosted trunk bots all the same (so they all have the
same DARWIN_*_archs, and we don't easily know if a mac host bot is
targeting mac or ios at the place where we call cmake), but only the
ios-targeting bots have ios sysroots available.
This will hopefully unbreak that use case without impacting anything
else -- and it makes ubsan and asan test setup more alike.

This reverts commit 1bcdbd68616dc7f8debe126caafef7a7242a0e6b.
It's been reported that some bots are failing with this change with CMake
error like:
```
CMake Error at /b/s/w/ir/k/llvm-project/compiler-rt/cmake/config-ix.cmake:177 (message):

```
I'm reverting the patch now to unbreak builds. I will investigate properly when time permits.

This is a follow up to r341306.
The typo meant that if an architecture was a prefix to another
architecture in the list (e.g. `armv7` is a prefix of `armv7k`) then
this would trigger a match which is not the intended behaviour.

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:
As discussed in https://github.com/google/oss-fuzz/issues/933,
it would be really awesome to be able to use ThinLTO for fuzzing.
However, as @kcc has pointed out, it is currently undefined (untested)
whether the sanitizers actually function properly with LLD and/or LTO.
This patch is inspired by the cfi test, which already do test with LTO
(and/or LLD), since LTO is required for CFI to function.
I started with UBSan, because it's cmakelists / lit.* files appeared
to be the cleanest. This patch adds the infrastructure to easily add
LLD and/or LTO sub-variants of the existing lit test configurations.
Also, this patch adds the LLD flavor, that explicitly does use LLD to link.
The check-ubsan does pass on my machine. And to minimize the [initial]
potential buildbot breakage i have put some restrictions on this flavour.
Please review carefully, i have not worked with lit/sanitizer tests before.
The original attempt, r319525 was reverted in r319526 due
to the failures in compiler-rt standalone builds.

different construct. I missed this case in r315144.

As a follow-up to r315142, this makes it possible to use ubsan with a
static runtime on Darwin. I've also added a new StandaloneStatic testing
configuration so the new setup can be tested.

Summary:
Enable check-cfi and check-ubsan on Android.
Check-ubsan includes standalone and ubsan+asan, but not tsan or msan.
Cross-dso cfi tests are disabled for now.

in lit tests
The Clang driver on macOS decides the deployment target based on various things, like your host OS version, the SDK version and some environment variables, which makes lit tests pass or fail based on your environment. Let's make sure we run all lit tests with `-mmacosx-version-min=${SANITIZER_MIN_OSX_VERSION}` (10.9 unless overriden).

Summary:
This patch is a refactoring of the way cmake 'targets' are grouped.
It won't affect non-UI cmake-generators.
Clang/LLVM are using a structured way to group targets which ease
navigation through Visual Studio UI. The Compiler-RT projects
differ from the way Clang/LLVM are grouping targets.
This patch doesn't contain behavior changes.

It's fixing compilation errors. The runtime is not yet working.
Missing features:
OverrideFunction for x64
an equiv function for inline asm (atomic_compare_exchange_strong)
shadow memory offset needs to be adjusted
RoundUpToInstrBoundary for x64
They will be implemented by subsequent patches.

Summary:
Rather than having to add new "experimental" options each time someone wants to work on bringing a sanitizer to a new platform, this patch makes options for all of them.
The default values for the options are set by the platform checks that would have enabled them, but they can be overridden on or off.

Without the --target flag, clang uses the mips64 triple which selects the n64 abi. We need to add --target=mips-linux-gnu, so that clang can select the correct abi for mips32r2.

This commit broke the Windows build, where CMAKE_C_COMPILER can
compile and link with -march=armv7-a but the just-built-clang
cannot.

You can expect the sanitizers to be built under any of the following conditions:
1) CMAKE_C_COMPILER is GCC built to cross-compile to ARM
2) CMAKE_C_COMPILER is Clang built to cross-compile to ARM (ARM is default target)
3) CMAKE_C_COMPILER is Clang and CMAKE_C_FLAGS contains -target and --sysroot
