Shoaib Meenai f481256bfe [builtins] Build for arm64e for Darwin
https://github.com/apple/swift/pull/30112/ makes the Swift standard
library for iOS build for arm64e. If you're building Swift against your
own LLVM, this in turn requires having the builtins built for arm64e,
otherwise you won't be able to use the builtins (which will in turn lead
to an undefined symbol for `__isOSVersionAtLeast`). Make the builtins
build for arm64e to fix this.

Dan Liew 9d9b470e69 [CMake] Refactor iOS simulator/device test configuration generation code for LibFuzzer.
Summary:
In order to do this `FUZZER_SUPPORTED_OS` had to be pulled out of
`lib/fuzzer/CMakeLists.txt` and into the main config so we can use it
from the `test/fuzzer/CMakeList.txt`. `FUZZER_SUPPORTED_OS` currently
has the same value of `SANITIZER_COMMON_SUPPORTED_OS` which preserves
the existing behaviour but this allows us in the future to adjust the
supported platforms independent of `SANITIZER_COMMON_SUPPORTED_OS`. This
mirrors the other sanitizers.

For non-Apple platforms `FUZZER_SUPPORTED_OS` is not defined and
surprisingly this was the behaviour before this patch because
`SANITIZER_COMMON_SUPPORTED_OS` was actually empty. This appears to
not matter right now because the functions that take an `OS` as an
argument seem to ignore it on non-Apple platforms.

While this change tries to be NFC it is technically not because we
now generate an iossim config whereas previously we didn't. This seems
like the right thing to do because the build system was configured to
compile LibFuzzer for iossim but previously we weren't generating a lit
test config for it. The device/simulator testing configs don't run by
default anyway so this shouldn't break testing.

This change relies on the get_capitalized_apple_platform() function
added in a previous commit.

Dan Liew 8a5bfbe6db [CMake] Disable building all Darwin libraries (except builtins) for macOS i386 when the SDK is >= 10.15.
Summary:
In the macOS 10.15 SDK the ability to link i386 binaries was removed and
in the corresponding OS it is not possible to run macOS i386 binaries.

The consequence of these changes meant that targets like `check-asan`
would fail because:

* Unit tests could not be linked for i386
* Lit tests for i386 would fail due to not being able to execute
  compiled binaries.

The simplest fix to this is to simply disable building for i386 for
macOS when using the 10.15 SDK (or newer). This disables building the
i386 slice for most compiler-rt libraries and consequently disables the
unit and lit tests for macOS i386.

Note that because the `DARWIN_osx_ARCHS` CMake variable is a cache
variable this patch will have no affect on existing builds unless
the existing cache variable is deleted. The simplest way to deal with
this is delete existing builds and just do a fresh configure.

Note this should not affect the builtins which are managed with
the `DARWIN_osx_BUILTIN_ARCHS` CMake cache variable.

For those who wish to force using a particular set of architectures when
using newer SDKs passing `-DDARWIN_osx_ARCHS=i386;x86_64;x86_64h` to
CMake should provide a usable (but completely unsupported) workaround.

Dan Liew bbde056b88 [CMake] Fix the value of `config.target_cflags` for non-macOS Apple 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.

Hans Wennborg ec841cf36c [cmake] Strip quotes in try_compile_only
After r372209, the compile command can end up including an argument with
quotes in it, e.g.

  -fprofile-instr-use="/foo/bar.profdata"

when invoking the compiler with execute_process, the compiler ends up
getting that argument with quotes and all, and fails to open the file.

This all seems horribly broken, but one way of working around it is to
simply strip the quotes from the string here. If they were there to
protect a path that's got spaces in it, that wasn't going to work
anyway because the string is later split by spaces.

Dan Liew 713da8db39 Fix bug in `darwin_test_archs()` when the cache variable is set but empty.
Summary:
If the cache variable named in `${valid_archs}` (e.g. `DARWIN_osx_BUILTIN_ARCHS`)
is set in the cache but is empty then the cache check
`if(${valid_archs})` will be false so the function will probe the
compiler but the `set(...)` command at the end of the function to update
the cache variable will be a no-op. This is because `set(...)` will not
update an existing cache variable unless the `FORCE` argument is
provided.

To fix this this patch adds `FORCE` so the cache is always updated.

Dan Liew ef163f5a20 [CMake] Separate the detection Darwin platforms architectures for the
built-ins from the rest of compiler-rt.

The detection of supported platform (os) architectures for Darwin relies
on the `darwin_test_archs()` CMake function. This is used both for
building the builtins (`builtin-config-ix.cmake`) and for the rest of
the compiler-rt (`config-ix.cmake`).

`darwin_test_archs()`  implements a cache, presumably to speed up CMake
re-configures.  Unfortunately this caching is buggy because it depends
on external global state (i.e. the `TEST_COMPILE_ONLY` variable) and
this is not taken into account. For `config-ix.cmake`
`TEST_COMPILE_ONLY` is not set and for `builtin-config-ix.cmake`
`TEST_COMPILE_ONLY` is set to `On`.  This makes the
`darwin_test_archs()` function racey in the sense that a call from one
calling context will poison the cache for the other calling context.

This is actually an issue George Karpenkov discovered a while back
and had an incomplete patch for (https://reviews.llvm.org/D45337)
but this was never merged.

To workaround this, this patch switches to using a different set of
variables for the platform architecture builtins, i.e.
`DARWIN_<OS>_ARCHS` -> `DARWIN_<OS>_BUILTIN_ARCHS`. This avoids the
cache poisoning problem because the cached variable names are different.
This also has the advantage that the the configured architectures for
builtins and the rest of the compiler-rt are now independent and
can be set differently if necessary.

Note in `darwin_test_archs()` we also now pass `-w` to the compiler
because `try_compile_only()` treats compiler warnings as errors.  This
was extremely fragile because compiler warnings (can easily appear due
to a buggy compiler or SDK headers) would cause compiler-rt to think an
architecture on Darwin wasn't supported.

When cross-compiling compiler-rt as part of LLVM e. g. for Linux on
a Windows host and using the just-built clang as cross-compiler, we set
the -DBUILTINS_CMAKE_ARGS="-DCMAKE_SYSTEM_NAME=Linux" flag in top-level
cmake invocation, which causes CMAKE_EXECUTABLE_SUFFIX to be an empty
string in the nested cmake invocation for building builtins.

But the compiler for compiling test cases is meant to be run on host,
therefore it may have the '.exe' suffix.

Handle this by asking cmake about the host system.

Jonas Devlieghere 4d474e078a [CMake] Check for C++14 instead of C++11
Now that LLVM moved to C++14, `COMPILER_RT_HAS_STD_CXX11_FLAG` should
become `COMPILER_RT_HAS_STD_CXX14_FLAG`.

I ran into this issue when replacing llvm::make_unique with
std::make_unique in an X-ray unit test. We are correctly passing
`-std=c++14`, but this got overwritten further down the invocation by
the compiler-rt flags. Given that this unit test is using LLVM headers,
this is bound to break sooner than later, regardless of my change.

Alexander Richardson 51bfb84852 [compiler-rt] Fix running tests on macOS when XCode is not installed
Summary:
If XCode is not installed, `xcodebuild -version -sdk macosx Path` will give
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
In this case the variable OSX_SYSROOT will be empty and
OSX_SYSROOT_FLAG is set to "-isysroot" (without a path).
This then causes the CompilerRTUnitTestCheckCxx target failed to for me
because "${COMPILER_RT_TEST_COMPILER} ${OSX_SYSROOT_FLAG} -E" expanded to
"clang -isysroot -E". This results in a warning "sysroot -E does not exist"
and the target fails to run because the C++ headers cannot be found.

Rainer Orth 4a9a772f44 Enable compiler-rt on SPARC
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
    Builtins-sparcv9-sunos :: divtc3_test.c
[...]
    UBSan-Standalone-sparc :: TestCases/TypeCheck/misaligned.cpp
    UBSan-Standalone-sparcv9 :: TestCases/TypeCheck/misaligned.cpp

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.

Tested on sparcv9-sun-solaris2.11.

Kamil Rytarowski 983d7ddd0b Add NetBSD LSan support
Summary:
Combine few relatively small changes into one:

 - implement internal_ptrace() and internal_clone() for NetBSD
 - add support for stoptheworld based on the ptrace(2) API
 - define COMPILER_RT_HAS_LSAN for NetBSD
 - enable tests for NetBSD/amd64

Inspired by the original implementation by Christos Zoulas in netbsd/src for GCC.

The implementation is in theory CPU independent through well defined macros
across all NetBSD ports, however only the x86_64 version was tested.

Stefan Granitz f2ffa7320e Specify log level for CMake messages (less stderr)
Summary:
Specify message levels in CMake. Prefer STATUS (stdout).

As the default message mode (i.e. level) is NOTICE in CMake, more then necessary messages get printed to stderr. Some tools,  noticably ccmake treat this as an error and require additional confirmation and re-running CMake's configuration step.

This commit specifies a mode (either STATUS or WARNING or FATAL_ERROR)  instead of the default.

* I used `csearch -f 'llvm-project/.+(CMakeLists\.txt|cmake)' -l 'message\("'` to find all locations.
* Reviewers were chosen by the most common authors of specific files. If there are more suitable reviewers for these CMake changes, please let me know.
